Ethical risks from the use of technology.

ABSTRACT

The pervasive use of modern technology has resulted in law firms increasingly creating and maintaining files, litigation materials, confidential client information and other data in digital form. This form of data is easy to update, transfer and search. Hence, it can save time and increase efficiency while minimizing errors. Nevertheless, certain risks accompany use of digital data. For example, client data must be maintained in confidence. It must be preserved so that it can be recovered in the future if it is needed. Also, it must be preserved such that it can be produced with reasonable assurance it is in its original unmodified form. These risks create the potential for an attorney to run afoul of rules of professional conduct. To avoid this, an attorney today must be both cognizant of these risks and take reasonable steps to minimize such risks. This article will identify these risks, identify the applicable rules of professional conduct and suggest reasonable actions an attorney must take to avoid violating these rules.

CONCLUSION

INTRODUCTION

Many aspects of the practice of law have changed over the last two decades. The use of technology has dramatically increased. (1) Attorneys typically do not rely on support staff to take notes in shorthand. Dictating devices, carbon paper and IBM Selectric typewriters are no longer ubiquitous items in a law office. Today, computers appear almost universally in law offices on the desks of both support staff and attorneys. (2) Documents are created both by support staff and attorneys on computers using popular word processing software such as WORD or WORDPERFECT. Drafts may be electronically transmitted from an attorney's desktop computer to a support staff member via an internal network since connecting office computers together via a network is relatively easy and inexpensive and consequently quite common today. The widespread and inexpensively priced availability of both dialup and high speed Internet connections has resulted in office computers being connected both to internal networks and to the external Internet, Internet connections allow broad access to information and resources used by attorneys. The Internet enables mundane uses such as e-mail or instant-messaging. (3) Additionally, searching case law and other types of research are increasingly being conducted via the Internet. Large commercial databases such as LEXIS-NEXIS (4) and WESTLAW (5) provide instantaneous access to virtually all U.S. law and many other resources. (6) Many courts now provide information, including in some cases complete opinions, via websites on the Internet. (7) Non-profit services such as the Cornell Legal Information Institute at Cornell Law School provide free automatic e-mails alerting subscribers to recent Supreme Court decisions. (8) It is also quite common for law firms to maintain extensive web sites available to anyone with Internet access. (9) Finally, electronic communications with clients is increasingly common. It can include simply exchanging e-mails or sending documents as e-mail attachments. (10) More advanced uses can involve communal editing of documents by individuals at different locations via electronic connections over the Internet. (11)

The widespread use of computer technology in the practice of law is here and will continue to grow as business and commercial enterprises continue an ever increasing reliance on such technology in the interests of efficiency and profit maximization. (12) Consequently, attorneys will continue to use such technology since it will be demanded by clients. Such reliance on computers can raise ethical risks for attorneys. (13) This article addresses the general ethical issues which are a concern. It then provides a primer on technology issues that can trigger ethical concerns. Finally, it offers recommendations on minimizing running afoul of these ethical concerns in the practice of law.

I. ETHICAL CONCERNS THAT ARISE FROM THE USE OF COMPUTER TECHNOLOGY IN THE PRACTICE OF LAW

A. Maintaining confidential nature of client information

In the course of representing clients, lawyers receive confidential information. Such information may relate to the client personally or to a business enterprise she is involved in. Maintaining the confidentiality of such information is a basic premise of the U.S. legal system. (14) It enables a client to freely speak with an attorney in the course of a client-attorney relationship. (15) Absent this ability, a client would may be unwilling to freely communicate with his or her lawyer thereby making it difficult for the attorney to represent the client to the best of his or her ability. (16) Consequently, attorneys are required to maintain the confidentiality of most client information.

The ABA Model Rules of Professional Conduct provide, in part:

RULE 1.6: Confidentiality of Information

   (a) A lawyer shall not reveal information relating to the
   representation of a client unless the client gives informed
   consent, the disclosure is impliedly authorized in order to carry
   out the representation or the disclosure is permitted * * * by
   [certain limited and specific situations]. (17)

Official comments to Rule 1.6 state, in part:

   A lawyer must act competently to safeguard information
   relating to the representation of a client against inadvertent or
   unauthorized disclosure by the lawyer * * *. (18)

When transmitting a communication that includes information relating to the representation of a client, the lawyer must take reasonable precautions to prevent the information from coming into the hands of unintended recipients. This duty, however, does not require that the lawyer use special security measures if the method of communication affords a reasonable expectation of privacy. Special circumstances, however, may warrant special precautions. "Factors to be considered in determining the reasonableness of the lawyer's expectation of confidentiality include the sensitivity of the information ... A client ... may give informed consent to the use of a means of communication that would otherwise be prohibited by this rule." (19) "The duty of confidentiality continues after the client-lawyer relationship has terminated." (20)

Representation of a client often requires an attorney to utilize non-attorneys which may include support personnel, paralegals, accountants, investigators, law student interns and experts. (21) Ethical rules binding attorneys do not bind non-attorneys. (22) However, an attorney may be responsible for insuring that such personnel comply with the ethical obligations binding the attorney. (23) Hence, an attorney must take appropriate steps to insure that all personnel, including technology staff, safeguard confidential client information. (24)

The ABA Model Rules of Professional Conduct provide, in part:

RULE 5.3: Responsibility Regarding Nonlawyer Assistants

With respect to a nonlawyer employed or retained by or associated with a lawyer:

(a) a partner, a lawyer who individually or together with other lawyers possesses comparable managerial authority in a law firm, and the law firm shall make reasonable efforts to ensure that the firm has in effect measures giving reasonable assurance that the person's conduct is compatible with the professional obligations of the lawyer;

(b) a lawyer having direct supervisory authority over the nonlawyer shall make reasonable efforts to ensure that the person's conduct is compatible with the professional obligations of the lawyer; and

(c) a lawyer shall be responsible for conduct of such a person that would be a violation of the Rules of Professional Conduct if engaged in by a lawyer if:

(1) the lawyer orders or, with the knowledge of the specific conduct, ratifies the conduct involved; or

(2) the lawyer is a partner or has comparable managerial authority in the law firm in which the person is employed, or has direct supervisory authority over the person, and knows of the conduct at a time when its consequences can be avoided or mitigated but fails to take reasonable remedial action. (25)

Official comments to Rule 5.3 state, in part:

   Lawyers generally employ assistants in their practice,
   including secretaries, investigators, law student interns, and
   paraprofessionals. Such assistants, whether employees or
   independent contractors, act for the lawyer in rendition of
   the lawyer's professional services. A lawyer must give
   such assistants appropriate instruction and supervision
   concerning the ethical aspects of their employment,
   particularly regarding the obligation not to disclose
   information relating to representation of the client, and
   should be responsible for their work product. The
   measures employed in supervising nonlawyers should take
   account of the fact that they do not have legal training and
   are not subject to professional discipline. (26)

   [The Rule] * * * requires lawyers with managerial
   authority within a law firm, and the firm itself, to make
   reasonable efforts to establish internal policies and
   procedures designed to provide reasonable assurance that
   nonlawyers in the firm will act in a way compatible with
   the Rules of Professional Conduct. (27)

B. Meeting the reasonableness standard

The above ethical rules and official comments generally require attorneys to take reasonable steps (28) to insure client confidentiality is maintained both by the attorney and other employees and agents who have access to client information in the normal representation of a client. (29) Reasonableness, which is a basic standard used in negligence law, (30) is a variable standard. (31) The existing state of technology, the general customs in a particular profession, a cost-benefit ratio, potential risks and consequences, and the typical knowledge of persons in the particular profession all relate to determining reasonableness. (32) Additionally, an obligation to inquire or ascertain relevant information may be applicable to whether reasonable conduct has been engaged in. (33)

In light of this, it is important to fully understand the potential risks of reliance on technology as a prerequisite to evaluating the reasonableness of conduct. (34) Knowledge of such risks and the corresponding consequences provide a baseline for knowing what actions must be taken to maintain confidential client information. Additionally, it also facilitates determining what actions, such as employee training, may be necessary to meet the reasonableness standard.

The next section examines the technological risks that can potentially compromise confidential client information in today's computerized law firm environment. It also discusses methods and techniques for minimizing such risks.

II. DATA SECURITY ISSUES ARISING FROM THE USE OF DIGITAL DATA

A. Introduction

Movement from paper documents to digital documents has many advantages. It is easier to manage documents because they can be more easily stored, located, indexed, reproduced, modified and searched. (35) However, these same advantages increase opportunities for inadvertent disclosure of confidential data and unauthorized acquisition of such documents. (36) If attorneys and other law firm personnel are not adequately informed or trained, numerous opportunities exist for the inadvertent release of confidential client data. (37) Additionally, reliance on digital data makes unauthorized deliberate diversion or acquisition of documents by both employees and third parties easier to achieve as compared to an environment utilizing paper documents. Reliance on digital data combined with networking of computers, both internally and externally, makes it easier for unauthorized diversion of documents to go undetected. Finally, inadequate precautions can result in unintended loss of digital documents (38) as well as the risk that documents can be the subject of unauthorized alteration. (39)

B. Low-tech access--physical security measures

The ease with which digital data can be accessed, searched and copied makes controlling access to digital data critical. The most basic risk to digital data is an unattended computer. During the work day, employees and vendors installing software, and technical personnel may have access to computers. Additionally, after hours both maintenance staff and cleaning contractors routinely have access to office space which gives them access to any unattended computer. (40)

Computers are ubiquitous tools scattered about the majority of workplaces today. They handle the many tasks--both mundane and complex--that are necessary to operate a law firm or other enterprise. Nevertheless, each computer is like a file cabinet containing both firm and client data. Additionally, a networked computer is like a door into a room containing all of the firm's and clients' data. In light of this, physical security measures are critical. If a firm would not leave all its data and files openly available on an unrestricted basis to all personnel, then it should not do the same thing with office computers.

Thus, the location of computers should be evaluated in light of who needs access to particular machines. Also, it should be determined if all machines need to be networked. Disks, CDs, backup tapes and any other portable data media should not be left in easily accessible locations. At a minimum, such media should be kept in a locked desk drawer or file cabinet.

C. Passwords

Passwords, a commonly used security device, are employed by many devices and systems, such as ATMs. At a minimum, all computers should have a password installed that must be entered before anyone will be able to use the computer. Typically, this means the computer should have a password that is required to access computer data when it is turned on. Additionally, in many workplaces, computers are left on all the time. Such machines should lock out users by requiring a password. The ability to add such passwords is already built into most computers. It merely requires a few steps to be activated.

The use of passwords will only be effective if an appropriate password policy is utilized. This means that employee passwords should not be names, phone numbers, birth dates or other things which can be easily guessed. (41) Preferably, passwords should include numbers, letters and other characters. Additionally, they should be case sensitive so that capital and small letters can be mixed together. (42) The computer network can be programmed so that it only accepts proper passwords. If an employee attempts to create an improper or weak password, the system can be setup so that it rejects it and provides a pop-up window explaining what was wrong with the password. Finally, passwords should be periodically changed. (43)

The proliferation of passwords needed by employees often undermines the above policies. Today, an attorney might have a power-on password (44) on her computer, a network log-on password, an e-mail password, a WESTLAW password and a LEXIS-NEXIS password. Additionally, she may have an ATM password, a phone card password and other passwords for a variety of things. The average person will have difficulty remembering so many different passwords. Hence, users tend to pick easy to remember passwords such as names, phone numbers, etc. If the above password policy is put in place so that such weak passwords cannot be used, another common problem often occurs. The user will write down the passwords in a convenient place such as on a Post-It note stuck to the side of the monitor or inside a desk drawer. (45) Obviously, such conduct defeats the purpose of any password policy.

One solution is to create a single password system. Employees often dislike having to use several strong, arbitrary passwords. (46) Periodically changing passwords is universally disliked. Consequently, a good compromise is to enable users to have only a single password for everything. Such a system can store passwords for a variety of systems or services that will automatically be sent, as appropriate, when the single password is entered.

D. Protecting data integrity

As documents and related data are increasingly being kept only in digital form, (47) it is important to maintain the integrity of the data so that it can be retrieved and used, as needed, in the future. Insuring such integrity requires attention to a number of technological issues and concerns.

1. Data backups

First, all digital data should be backed up on a regular basis. (48) A variety of storage devices exist today for such backups. (49) Additionally, simple software exists which enables a computer to automatically back itself up on a regular basis with only minimal human intervention.

It is common for networks to backup data onto a second hard drive or magnetic tape or both. In a networked office environment, individual desktop computers can store all data files on a network server which can then be backed up on a regular schedule. If data files are stored on individual desktop computers, back ups can be automatically made over the network. Additionally, inexpensive external hard drives can be connected to desktop computers for backing up data locally. (50) Such hard drives can be set up to automatically backup all files as they are changed in real time by the computer user.

Critical data can be backed up to off-site locations. Companies exist today that provide secure off-site data backups for a monthly fee. (51)

2. Virus protection

It is a fact of life that malevolent individuals will create and disseminate software code whose sole purpose is to interfere with the use of computers. Such code, commonly called a virus, (52) may have only minimal effects on a computer or computer network. (53) In contrast, some viruses can destroy data and completely cripple a computer or network. Avoiding viruses is impossible. Nevertheless, some simple precautions can substantially eliminate the risk associated with viruses.

The first level of defense is installing virus protection software on all computers. This software is commonly available at a relatively low cost. (54) Virus protection software must be updated on a regular basis or it rapidly becomes useless. Most of these programs can be setup to automatically download new virus definitions over the Internet on a regular basis. Weekly updates are a necessity if this software is to be an effective tool. (55)

If computers are networked in an office environment, virus updates can be sent to all desktop computers automatically via the network. This is often a better alternative than relying on individual computer users to update the software.

Virus creators often exploit known flaws in operating system software. (56) Microsoft Windows, the operating system used on most computers, is a favorite target of virus creators. (57) To thwart these individuals, Microsoft makes available software updates or patches to fix such flaws. These updates are available from Microsoft for free via the Internet. (58) Windows can even be configured to automatically notify the user or automatically download and install these updates or both. In many cases, regularly installing these updates will immunize your computer from new and disruptive viruses. (59)

E-mail has become a source of unwanted mail (commonly called SPAM). (60) Such e-mail is clearly an annoyance. However, it can also provide a gateway for viruses to infect a computer or a computer network. Traditionally, most such viruses were contained in e-mail attachments. (61) Enterprising virus creators have expanded their attacks so that viruses can be obtained even from e-mail without attachments. (62) Nevertheless, a few simple actions can greatly minimize the likelihood of viruses affecting a computer. (63) First, most antivirus programs can be set up to scan e-mail for viruses. (64) Second, e-mail systems can be configured to reject all e-mail attachments. Although blocking all attachments is very effective, it may compromise usability of e-mail such that it is counterproductive. (65) A middle ground is to only block certain types of e-mail attachments such as types most likely to contain viruses. (66) These are generally not the types of files routinely sent as file attachments, so in most cases this only has minimal effect on system usability. Finally, file attachments, which are unexpected (67) or from unknown users, should never be opened.

3. Spyware protection

In addition to viruses, both legitimate enterprises and malevolent individuals have created and disseminated programs that illicitly collect and transmit data from a computer. Typically, these programs, called spyware, (68) are unintentionally downloaded to a computer from the Internet. (69) Often they are included, without any notice or warning, in things that are downloaded from the Internet. (70) For example, downloading a free software program from the Internet may result in unwanted software being downloaded without your knowledge. (71) Such software may come from a commercial enterprise which collects data on the web sites you visit on the computer, or it may be a program that collects critical data, such as usernames and passwords for later use in illegally penetrating the computer from a remote location. (72)

Relatively inexpensive software is available both to block such software from downloading and to remove any such software that is on a computer. (73) Like antivirus programs, this software should be updated frequently and run on a periodic basis. (74)

4. Computer use policy

A clearly thought out computer use policy is critical to protecting data integrity. (75) Such a policy should be reduced to an understandable written form that is disseminated to everyone. (76) The policy should be tailored to the particular enterprise since that will dictate the type of computer restrictions which are reasonable and those that are unreasonable and hence interfere with day-to-day work. (77)

For example, employee access to the Internet may be difficult to limit if such access is needed on an on-going basis by employees. In contrast, limiting such access may be both reasonable and desirable if it is not necessary for the day-to-day activities of employees.

In today's business world, unlimited e-mail access is a necessity in most work environments, including law firms. However, reliance on SPAM filters, clear rules about dealing with attachments and blocking certain types of e-mail attachments can significantly reduce any problems related to e-mail usage. Additionally, both attorneys and employees need to be educated about what should and what should not be written in an e-mail message in light of the relative permanence of such writings. (78)

A rigid rule should exist, in most cases, barring the installation of any software without permission. Installation of unauthorized software can inadvertently infect a computer and the network it is connected to with viruses and/or other unwanted software. (79) Additionally, disks, CDs or other media from home should not be used in office computers. Again, this can inadvertently introduce viruses and/or unwanted software into the system. (80)

5. Firewall software

Any computer connected to the Internet is a potential target for third parties trying to gain unauthorized access to the computer. Hackers seeking to damage or steal data and other unauthorized users constantly probe systems looking for easy entry. Firewall software blocks a large amount of unauthorized entry. (81) Hence, it should be installed on all computers that are connected to the Internet. This software, once installed, runs in the background. The newest version of the Windows operating system, Windows XP, contains a built in firewall which merely has to be turned on for it to be made operational. More robust firewall software is also available and is relatively inexpensive. (82)

6. Attorney and employee education

It is critical that attorneys and employees are educated about the risks of using computers and relying on digital data. (83) Only day-today adherence to appropriate practices can insure data integrity. However, adherence to such practices will only occur if computer users understand the need for such practices. Education in the form of periodic meetings and written computer use policies can emphasize the importance of such practices. (84)

7. Modems and wireless access points

If desktop computers in an office environment are connected to the Internet via an internal network, any dial-up modems (85) on individual computers should be removed or disconnected. Additionally, employee-installed wireless access points, (86) which are easily installed in an office to allow use of a wireless-enabled laptop, should be removed. Both of these devices allow easy unauthorized third party access to the network. (87) A dial-up modem connected to a phone line (88) and an unencrypted wireless access point may effectively allow a third party to bypass all security measures utilized to protect the network and computers connected to the network. (89)

8. Automating data integrity protections

The above recommendations may seem daunting to anyone other than a computer programmer. However, backup programs, antivirus programs and antispyware programs can be setup to run automatically. (90) For example, computers can be left on at night and the above programs can be setup to run automatically at 2 AM on a nightly basis. This provides significant protection with minimal human intervention. (91)

9. Storage media longevity

It is unknown how long various data storage media, such as disks, tapes, CDs or DVDs, will last. Storage media which rely on magnetic technology, such as disks and tapes, are prone to failure over time. (92) CDs and DVDs, when introduced, were generally believed to have a very long lifespan since they did not rely on magnetic technology. (93) However, mishandling of CDs and DVDs, and defects in manufacturing can shorten the life of this media substantially. (94) Consequently, it is advisable to store client data on multiple media to ensure that it is accessible in the future. Additionally, storing it off-site at a commercial data backup facility may be necessary to ensure future access to the information.

E. Traveling--security concerns

Traveling with a laptop computer is a commonplace occurrence for attorneys. It allows you to carry with you a substantial amount of data and documents in digital form. (95) This can include e-mails, correspondence, client files, research and work-product such as briefs or memos. (96) Additionally, usernames and passwords for accessing e-mail and other networks are often on a laptop. Frequently, usernames and passwords may be permanently stored in an application, such as an e-mail program, so anyone using the computer can access this application.

Some basic hazards can arise from traveling with a laptop. First, users should be cognizant of the files they are using in relation to whether they are in a public or private area. It may not be advisable to display confidential data or information on a computer screen if unknown third parties can view the screen. For example, on an airplane nearby passengers can easily view your laptop screen.

Increasingly, hotels provide wireless Internet access for laptops. Restaurants (97) and other places also provide so-called "hotspots" where wireless Internet access is available. (98) This allows a user to send or receive e-mail. Often, the office network can be connected to via a wireless hotspot. This allows convenient sharing of documents and other information while traveling. However, such wireless access is not risk free. First, public wireless networks are typically not secure. (99) This means data transmitted between your laptop and the wireless receiver/transmitter is sent unencrypted. This can allow third party interception of usernames, passwords, emails and documents. Password interception can be particularly problematic since it can enable unauthorized third party access to your office network. This provides another reason to periodically change e-mail and network access passwords.

Accidental loss or theft of laptops is also a concern since it can allow third parties to obtain data stored on the laptop. (100) Additionally, it may allow unauthorized access to your e-mail account and office network if usernames and passwords are stored on the laptop. Use of a laptop password can act as a first defense to unauthorized access to the machine. Such a password must be entered before a user can access files on the laptop. However, typically such passwords can be overcome. As a result, increasingly more travelers carry confidential or sensitive data on small memory devices called "key-chain drives." (101) Such devices are actually memory chips whose capacity during the last year has greatly increased while their price has substantially decreased. Currently, small pocket sized key-chain drives cost less than one-hundred dollars and can hold over one-hundred megabytes of data. (102) These devices have no moving parts which makes them very reliable. Additionally, they can be plugged into virtually any computer with a USB port. (103) Once attached, the computer views them as simply another hard drive or storage device which you can read data from or store data to. (104) Software is even available to encrypt the data on the key-chain drive. (105) Using one of these devices allows confidential data to be carried separately from a laptop so loss of the laptop will not result in loss of the data. (106)

Another method of protecting confidential data is to only maintain it on a computer at the office which can be accessed via the Internet. A remote laptop user can connect to the office computer from any location, worldwide, where Internet access is available. Such systems have been in use for a long time. However, the level of security varies considerably on such systems. (107) Some simply require a username and password to connect to them. Then unencrypted data is exchanged between the office computer and the remote laptop. This arrangement provides the lowest level of security--especially when a wireless Internet connection is utilized. A more secure method involves using a virtual private network (VPN) Internet connection. (108) A VPN provides an encrypted connection which has a high level of security. (109)

F. Unintended document replication

A rule of thumb with regard to digital data is that once you create a document on a computer it may be impossible to retrieve and/or destroy all copies of that document. For example, many word processing programs, such as Microsoft WORD or WORDPERFECT, are set up to automatically save backup copies of all documents created. (110) Documents stored on a server, which is becoming more common today, (111) are often periodically backed up on removable storage media such as magnetic tape. (112) Deleted documents, as noted below, (113) are still often recoverable. Copies of documents are often shared among various individuals. (114) Frequently, they are shared in electronic form either by delivering a disk to another party or by sending the file as an e-mail attachment. Sending such attachments can create numerous copies including a copy in the "sent" mailbox of the document originator and a copy in the "in" mailbox of the recipient. (115) Additionally, if the mail system mailboxes are on a server or network, it may be periodically backed up so that an additional copy exists on a backup media for the sender's mail system and on a backup media for the recipient's mail system. (116)

In litigation, copies of electronic media are commonly sought during discovery. (117) Consequently, many documents which were not intended to be available may become accessible to opposing counsel due to copies of documents which were unintentionally created and retained. (118)

G. Equipment replacement issues

Rapidly advancing technology has resulted in a short lifespan for computers. Typically, desktop computers and laptops are replaced every three to five years. (119) Most computers today have relatively large hard drives which accumulate massive amounts of data during the computer's lifespan. When a computer is disposed of, the hard drive can easily be removed and much of the stored data can be retrieved from the hard drive. Even deleted files can be retrieved from the hard drive with conventional software tools. (120)

Two solutions exist for preventing confidential data from being recovered from hard drives on old computers. The most effective solution is to remove and physically destroy hard drives prior to disposing of old computers. (121) A second solution is to use software which erases data on the hard drive in such a way that it is very difficult to retrieve it. (122) Typically, such programs write random data multiple times on every part of the hard drive. (123) The result is that it is extremely difficult, although not impossible, to recover any data files. (124)

The same issues that apply to hard drives apply to floppy disks, zip disks and magnetic tapes. Consequently, these media should be physically destroyed prior to disposal. Likewise, other data storage media, such as CDs, should also be physically destroyed before they are discarded. It may also be advantageous to avoid repeated reuse of such media. Otherwise, such media can end up "floating" around the enterprise with sensitive data on them.

It may be advantageous to consider a computer storage media retention policy analogous to such policies adopted today for paper files. Pursuant to such policies, paper documents, in many companies, are periodically destroyed. Such destruction has typically involved shredding. However, recently many companies have switched to outside contractors who pulverize discarded documents to ensure that they can not be reconstructed. (125) Similar policies for computer data would involve periodic permanent physical destruction of hard drives and other computer data storage media.

Increasingly, much of the conventional office equipment in use today contains computer data storage devices. For example, modern fax and copy machines use scanning technology which involves creating and storing a digital image of the document being faxed or copied. In the future, it may be necessary to ascertain if data can be retrieved from such storage media devices; and, if such retrieval is possible, it may be critical to permanently erase or physically destroy any storage media prior to the disposal of office equipment.

H. Legacy support issues

Computers are a relatively young technology which means hardware, software and standards continuously evolve. As computers continuously become more powerful, software becomes more sophisticated. This can result in a legacy problem when the newest versions of software are unable to read older files. (126) As a result, maintaining client files in digital form means they must be converted to new file types as new versions of software are utilized. This is an unreasonable approach, however, because it would require continuously converting files. In contrast, another approach involves maintaining old copies of programs to insure files maintained in digital form will be readable in the future. This latter approach was recommended in a recent Maine ethics opinion addressing storage of client data in digital form. (127)

I. The hidden data problem

Modern software, such as the widely used EXCEL spreadsheet program, PowerPoint and the ubiquitous word-processing program WORD, often store hidden data in documents created with these programs. (128) Such data, called "metadata," (129) enhances certain software features such as editing. Typically, metadata is hidden in the sense that it is not immediately visible when opening a file. (130) Some of this data can be easily retrieved with minimal effort. However, other data is more deeply hidden in the sense that it is difficult to retrieve.

If an attorney only provides printed versions of documents, called hard-copy, hidden data is not an issue. (131) However, attorneys increasingly receive and send data in digital form. (132) This can be problematic if the digital document contains metadata. The recipient of the document or some third party may be able to extract metadata from the document at a later date. Such data might contain confidential information that a client does not wish to disclose. (133)

Several solutions exist to this problem. First, documents can be converted into "portable document format" which creates a graphical image of the original document. (134) Typically, hidden data is not copied into this document format. Additionally, this document format is commonly used today so most recipients should be able to open such documents easily. The one negative is that documents in this format can not be easily edited.

The second solution is to use a software utility to remove metadata from documents as a routine matter once a document is completed. (135) This prevents retrieval of metadata from the document. It may also reduce the effectiveness of editing since such features as undelete may no longer be able to retrieve previously deleted data. However, the document can still be subject to new changes or modifications unlike a document in a graphical format which is difficult to change or modify once it is created.

J. The need for computer personnel

As computers and related technology have moved into both the business and legal world, the need for secretarial assistance has decreased in some cases. However, the increasing complexity of computer systems and the need to maintain data integrity and block unauthorized access may necessitate law firms hiring technology staff. Most large law firms already employ technology specialists. Medium and small firms may likewise have to hire such personnel. Failure to do so may be considered unreasonable conduct leading to liability in the event confidential client data is disclosed, lost or otherwise compromised.

CONCLUSION

Reliance on paper documents could avoid many of the issues discussed in this article. However, the use of computers and digital data is, and will continue to be, a fact of life in the legal world. Moreover, businesses today rely on computer data transmission and storage so attorneys will have to utilize such technology to serve clients. In light of this, attorneys must become educated about the use of digital data and the potential risks of utilization and storage of such data. Appreciation of these risks will allow attorneys to take reasonable steps to preserve client data in accordance with ethical obligations.

On June 22. 2004. a study released by Massachusetts found that the computer system used by the state court system was insecure. Unauthorized parties could easily obtain access to e-mail, court files and other digital data stored on the network. Among other things, the study found that hundreds of former employees still had access to the system. Additionally, employees were not required to change passwords on a regular basis.

(65.) See Richard J. Dalton Jr., Catching E-Mail Bad Apples, New Tactics to Keep Tainted Files Away, NEWSDAY, Feb. 17, 2004, at A47 (noting that blocking all e-mail attachments is not practical).

(66.) Typically, viruses are contained in program files or other executable files. Such files commonly have the file extensions ".com," ".exe," or ".vbs." See Canter, supra note 52, at 66.

(67.) Some viruses "hi-jack" the address book in an e-mail program and send virus-laden attachments to everyone listed in the address book. See generally Erlanger, supra note 55, at 84; Russell Glitman, Mail Utilities: From Juggling Multiple E-mail Accounts and Swatting Swarms of Junk Mail to Managing Business Correspondence Around the Clock, It's No Wonder E-mail Can Drive You Crazy, PC MAG., June 17, 2003, at 18. Hence, even if an attachment appears to come from a known sender, it should not be opened if it is unexpected. First, an e-mail can be sent to the sender asking if she sent an attachment. Only when she verifies having sent the attachment should it be opened.

(68.) Spyware, also sometimes referred to as "adware," refers to "a wide range of software programs that track a computer user's online activities and often flood the screen with annoying pop-up ads." Mary Kissel, Lawmakers Move Toward Placing Restrictions on Spyware Programs, WALL ST. J., June 24, 2004, at D2. In response to the growing spyware problem, Dell Inc., the large computer manufacturer, has launched a web page containing information to help consumers eliminate viruses and spyware from their computers. Russell Gold, Dell Debuts Site in Battle Against Spyware, Viruses, WALL ST. J., July 20, 2004, at D2. The increasing sophistication of spyware has exacerbated the problem. As a result, it is easier for it to surreptitiously infect a computer, it is frequently more harmful and it is often difficult to eradicate. Lee Gomes, Spyware Is Easy to Get, Difficult to Remove, Increasingly Malicious, WALL ST. J., July 12, 2004, at B1.

(69.) See Gomes, supra note 68.

For information on Ad-Aware and to download a free version for personal use, see http://www.lavasoft.de/(last visited Aug. 19, 2004) (on file with the Rutgers Computer and Technology Law Journal). Additionally, antivirus programs may catch some of these unwanted programs. It may also be beneficial to install pop-up blocker software. Pop-up ads, which are ads that pop-up in their own window when you are web browsing, are becoming popular. Such ads can be both an annoyance and a source of unwanted software being loaded on your system. Numerous free and inexpensive pop-up blocker programs are available. Additionally, the next version of Microsoft's Internet Explorer (software used to surf the Internet) is supposed to contain built in pop-up blocker software. See Patrick Marshall, Microsoft's Big Fix, SEATTLE TIMES, Aug. 28, 2004, at C6.

(85.) Dial-up modems (also called ordinary modems) are devices which allow a computer to connect to the Internet via an ordinary copper phone line. See WEBOPEDIA at, http://webopedia.internet.com/quick_ref/ dialup_modem_standards.asp (last visited Aug. 19, 2004) (on file with the Rutgers Computer and Technology Law Journal). Sometimes this is referred to as dial-up Internet access. Issues with dial-up modems will slowly disappear as more and more computers and networks rely on high speed or broadband Internet access. Nevertheless, many current computers still include dial-up modems, which are often left connected to an active phone line even if the dial-up modem is no longer used. Similar devices called broadband modems, cable modems or DSL modems allow a computer to be connected to high speed or broadband Internet access as opposed to slower dialup Internet access. See TECHENCYLOPEDIA, at http://www.techweb.com/encyclopedia/defineterm?term=broadband&x=22&y=8 (last visited Aug. 19, 2004) (on file with the Rutgers Computer and Technology Law Journal).

(86.) Wireless access points are simply small devices that can be connected to most computers. They allow a wireless link between the computer and a laptop. Such devices are relatively inexpensive and installable on most computers in a matter of minutes. Additionally, wireless-enabled laptops are becoming standard today. "WiFi" is the term often used to refer to wireless Internet access. It is short for wireless fidelity which is "the signal standard used to transmit data over local networks using radio signals ..." Bob Tedeschi, Cyber Scout." Cutting the Cord, N.Y. TIMES, Dec. 7, 2003, sec. 5 at 6. The networks that handle WiFi are typically called "hot spots." Id.

(87.) See generally Suruchi Mohan, The Stuff of Nightmares: Remote Access Poses Security Risks that Will Keep You up at Night, COMPUTERWORLD, Jan. 2, 1995, at 66 (recognizing that the increased use of digital data which is remotely accessible increases security risks to such data). See also Hiawatha Bray, Laptops at the FleetCenter at Risk of Breaches, Attack, BOSTON GLOBE, July 22, 2004, at C1 (discussing the risk of wireless enabled laptops at the 2004 Democratic National Convention in Boston).

(88.) In the typical networked office environment safety precautions are located between the network and its connection to the Internet. Hence, if an individual computer user connects her computer directly to the Internet via a dialup modem she is effectively bypassing all network security safeguards.

(89.) Wireless access points are essentially radio receivers/transmitters. As such, the signals they send out cannot be contained. Thus, operation of an unencrypted wireless access point opens a potential doorway into the network which bypasses all network security measures. See generally Bruce Mohl, Tap into Neighbor's WiFi? Why Not, Some Say, BOSTON GLOBE, July 4, 2004, at C1 (noting that many people gain unauthorized access to wireless access points).

(98.) It is estimated that at least 15,000 hotspots will be available in the U.S and Canada by the end of the year. Such access is now available at Logan International Airport in Boston, Massachusetts. Id. On-line web sites even exist to facilitate finding hotspots. See, e.g., Find Public Access Wi-Fi Hotspots, at http://www.wifinder.com/index.php (worldwide directory of public access hot spots) (last visited Aug. 19, 2004) (on file with the Rutgers Computer and Technology Law Journal).

(99.) T-Mobile, a company that provides publicly accessible hot-spots in airports and a variety of other locations, has the following security policy on its website:

   The T-Mobile HotSpot network is based on evolving wireless
   technology and is not inherently secure. We therefore cannot
   guarantee the privacy of your data and communications while using
   the HotSpot service. Wireless LAN (local area network) services,
   like T-Mobile HotSpot, include over-the-air communications that may
   be illicitly intercepted by equipment and software designed for that
   purpose.

(120.) In U.S. v. Stulock, it was stated:

   that when a computer file is deleted, the contents of the file are
   not irretrievably lost. The space occupied by the file is flagged as
   available, and until new data is stored in that location the deleted
   file can be recovered using an undelete tool. In addition to the
   contents of the file, information about when the file was created,
   last modified, and last accessed can be recovered.

308 F.3d 922, 924 (8th Cir. 2002); see also Sheryl Canter, All Is Not Lost; Here's How to Get Back Data You Thought Was Long Gone-or How to Delete it for Good, PC MAG., Oct. 1, 2003, at 60 (recognizing that virtually any deleted file, even if it has been overwritten or the hard drive has been reformatted, can be recovered using specialized hardware and software).

(121.) The U.S. Department of Defense requires physical destruction of hard drives that contain top secret data. See infra note 123.

(123.) The U.S. Department of Defense standard for erasing files on hard drives involves overwriting data files multiple times. See The National Indust. Sec. Program Operating Manual, available at http://www.dss.mil/isec/nispom_0195.pdf (last visited Aug. 19, 2004) (on file with the Rutgers Computer and Technology Law Journal). This manual lists detailed erasure standards for different types of data storage mediums. See Manual at 8-3-5 to 8-3-6. However, if a hard drive contains "top secret" data it must be physically destroyed. Id. Commercial programs that meet the above Department of Defense erasure standards are generally available. For example, "Evidence Eliminator" is an inexpensive program that is very effective. For information on this program see http://www.evidenceeliminator.us/ (last visited Aug. 19, 2004) (on file with the Rutgers Computer and Technology Law Journal). "Eraser" is a free program which is also available. See http://www.heidi.ie/eraser/(last visited Aug. 19, 2004) (on file with the Rutgers Computer and Technology Law Journal).
