Portwise 4.0.After a false start, Voice over Internet Protocol See Internet and TCP/IP. (networking) Internet Protocol - (IP) The network layer for the TCP/IP protocol suite widely used on Ethernet networks, defined in STD 5, RFC 791. IP is a connectionless, best-effort packet switching protocol. (VoIP) is taking off-according to recent research, the global market for VoIP will reach $82 billion this year and $196.5 billion by 2007, and much of this growth is driven by the enterprise, with the IT sector the most enthusiastic adopter. However, many businesses are failing to realise how the technology will revolutionise security in the data centre. The key problem is that convergence represents a step change in the number of points in the network for unauthorised access and denial of service A condition in which a system can no longer respond to normal requests. See denial of service attack. . In order to address this issue, it is more critical than ever for companies to ensure they have a comprehensive security policy that addresses securing physical connection, audit trails and policy based A decision made by any software application that is based on the policy (rules and regulations) of the organization. See policy and COPS. access decisions. 'The key security issue with introducing VoIP services onto a corporate enterprise is that it introduces the need for Internet security ''This article or section is being rewritten at Internet security is the process of protecting data and privacy of devices connected to internet from information robbery, hacking, malware infection and unwanted software. into the heart of the data centre, and there simply is not enough expertise in most data centres to cope with it. Earlier this year, an industry body, the Voice over IP Security Alliance The Voice over IP Security Alliance (VOIPSA) was launched in early 2005 to bring together Voice over IP and information security vendors, providers, and thought leaders to address current and emerging security threats to VoIP. , was formed to address this issue. Although it is yet to define the threats to IP telephony The two-way transmission of voice over a packet-switched IP network, which is part of the TCP/IP protocol suite. The terms "IP telephony" and "voice over IP" (VoIP) are synonymous. , it acknowledges that hackers are already developing methods to take advantage of this burgeoning communication system. Such threats could include filling a phone's voicemail with unsolicited advertisements, or programming all the telephones in an office to simultaneously call the same number, a pay-by-the-minute bogus number, for example. In order to address the exponential increase in the number of points for unauthorised access on a network that VoIP represents, it is critical for companies to adopt a holistic approach holistic approach A term used in alternative health for a philosophical approach to health care, in which the entire Pt is evaluated and treated. See Alternative medicine, Holistic medicine. to secure internal and external access to applications. The three key issues are securing the physical connection, audit trails and the ability to make policy based access decisions.
