Battling spam at the ISP level.Kaspersky Labs offers a new level of anti-spare protection developed specifically to filter spam at the level of Internet providers. Anti-Spam ISP (1) See in-system programmable. (2) (Internet Service Provider) An organization that provides access to the Internet. Connection to the user is provided via dial-up, ISDN, cable, DSL and T1/T3 lines. Edition allows Internet providers to solve the problem of system resources (1) In a computer system, system resources are the components that provide its inherent capabilities and contribute to its overall performance. System memory, cache memory, hard disk space, IRQs and DMA channels are examples. overload due to enormous volumes of spam. It operates at the level of Internet Service Providers Internet service provider (ISP) Company that provides Internet connections and services to individuals and organizations. For a monthly fee, ISPs provide computer users with a connection to their site (see data transmission), as well as a log-in name and password. , works under Linux and FreeBSD. The system recognizes, identifies and filters unsolicited mail messages when email is being received via SMTP (Simple Mail Transfer Protocol) The standard e-mail protocol on the Internet and part of the TCP/IP protocol suite, as defined by IETF RFC 2821. SMTP defines the message format and the message transfer agent (MTA), which stores and forwards the mail. protocol, hi this way, the filtering of spam is carried out before the message is delivered to the final recipients mailbox. The solution has a minimal effect on system performance in order to optimize the product for ISP use. The use of modem identification technology means that 90-95% of spam can be identified as such. These results are due to a series of new technologies developed by Kaspersky Labs. The combination of several filtration methods--linguistic analysis (encompassing not only the contents of the message, but also of all attached objects), formal analysis of message characteristics, the use of blacklists and whitelists, including RBL (Realtime Blackhole List) A list of the IP addresses of known spammers. See MAPS. (Realtime Black List)--enables the detection of the majority of undesirable messages. At the same time, the use of heuristic A method of problem solving using exploration and trial and error methods. Heuristic program design provides a framework for solving the problem in contrast with a fixed set of rules (algorithmic) that cannot vary. 1. analyser tools means that new varieties of spam can be effectively identified. The solution is able to protect the ISP user from the most insidious types of persistent advertising--effectively searching for and recognising random sequences of characters (symbols) contained in mail messages. Out of 100,000 messages, the number of messages falsely identified as suspicious ranged from between 1 to 10 messages. www.kaspersky.com |
