VoIP implementation and security concerns
The implementing of VoIP applications and the associated security concerns are leading to an increase in the sale of security applications, according to a research by In-Stat. According to the research, companies become more aware of the security aspect after they have installed VoIP. More than 60% of the respondents who stated their security apprehensions had already installed VoIP. Around 12% of the respondents who had security apprehensions were still in the planning stage.
Another fact that the research threw up was that companies with an employee strength of 500-1000 employees were more concerned about the security and many planned a security overhaul next year. This is because VoIP is susceptible to all the threats that currently plague the data networks, these include worms, viruses, spam, etc. Apart from these threats VoIP communication can be intercepted, the application be used for perpetrating a fraud, and sensitive information accessed via the call logs.
VoIP security is inconvenienced by the fact that there are no fixed standards and therefore the vendors sometimes find it a little difficult to add call-control security protocols. Traditional security application vendors are updating their existing products to provide VoIP security. SonicWall and Checkpoint have upgraded their firewall applications to support VoIP. TippingPoint, Borderware, and Ingate offer point products aimed at satisfying VoIP security protocols. Companies such as Cisco and Juniper have acquired other companies in order to support their converged networks.
The growth of VoIP will help the security appliance market to cross $7 billion by the year 2009. The availability of voice and data on a single network will result in a change in the manner in which network security is approached, there will be a shift from defense equipment on to the perimeter toward intelligent management of the traffic.
