One imaginative way to create dynamic return on security investment is to build in Voice over Internet telephony when implementing a large-scale IP CCTV project. In essence, the basic infrastructure for the two systems is the same, and the cost savings are potentially phenomenal – in some cases an entire IP CCTV system can be paid for in savings in telephony costs by the end of the first year of operation.
But before recommending this to your CEO, consider the downside of VoIP. Without stringent controls maintained by network managers and Internet service providers, VoIP communication are just as susceptible to hackers as unsecured WiFi connections to the Internet. A hacker could, for example, tap into a corporate VoIP system and listen to confidential calls. Another typical security risk involves hackers slipping into a call center using VoIP and listening as customers give sensitive information like Social Security numbers and financial account information to call center workers.
VoIP security is one of many subjects covered during the forthcoming Specifying Security Technology Course, 21-25 July 2008. Click below for details:
