Some of the same properties that make radio frequency communications so valuable--the abilities to cover relatively large distances and ignore walls and barriers--can make managing RF coverage difficult. Now EM-SEC Technologies says that its EM-SEC Coating will keep radio-frequency energy from penetrating a space that has been painted with the substance. EM-SEC developed the coating in response to the needs of the military and various government agencies that aren't supposed to really exist. For commercial customers, uses can include adding physical security to wireless networks, shielding control environments from operations RF, and segregating wireless network subnets.

File encryption (for every file on the device) and user training for safe use and physical security are additional measures that should be a part of the total corporate security plan.

How to choose the best VoIP security service

Sun, 06 Aug 2006 20:01:38 -0400

With a recent report indicating how advanced Voice over Internet Protocol (VoIP) capabilities when it comes to integrating voice with data in the next five years, the issue of security will continue to dominate the 'to-do' list for tech leaders. That's a primary driver pushing vendors to launch new security services and tools for enterprises jumping on the VoIP network bandwagon. There's such a slew of new options it can be a bit arduous determining which security approach is best, however. The first wave of choices features security assessment tools, which allow network managers to analyze network system architecture, business continuity plans and policies. Vendors are continually adding to the feature set providing scorecards on results, testing of hardware and firewall review. Some other services, such as Lucent's, even test the physical security of rooms where network hardware sits. Get a good look at what some other vendors and telcom providers are adding to their VoIP security solutions. Article
