SecureLogix Brings New Patent to VoIP Security

SecureLogix, a leader in VoIP (and unified communications) security, was awarded their first patent in 1998 when they introduced the first firewall for voice networks. As VoIP has grown and been embraced by corporations and consumers alike, SecureLogix has continued to innovate and develop new techniques that address evolving communications technologies as well as the threats and attacks designed to exploit those technologies.

This latest patent is their 14th. According to a MarketWatch article, the aspects of the latest patent include sensing and analyzing calls to determine call attributes, and performing security and/or management actions based upon the determined call attributes, including actions in response to attempts to encrypt a call or authenticate remote access, and monitoring of call content for keywords.

Cisco Patches CUCM Security Flaw

Cisco is preparing to launch the next release of their Cisco Unified Communications Manager (CUCM) product - CUCM 7.0. But, last week they released an update for the current CUCM release. Actually, they released a total of 12 security updates or patches, but 11 of them deal with Cisco’s IOS and only 1 of them is related to CUCM.

The CUCM threats have been rated by Secunia as ‘moderately critical’. Vulnerable systems may be exposed to denial-of-service (DoS) attacks from a successful exploit. You can get more information from the Cisco Security Advisory and download the appropriate updates directly from Cisco.

Securing Unified Communications

Corporate networks and computer systems are faced with a variety of threats. Unauthorized access, malware compromise, data leakage, and other threats are fairly common and administrators are used to protecting against them. However, the phone system traditionally has been a separate issue, exposed to soe threats of its own, but a horse of an entirely different color. Even the various attack vectors in the computer system and network infrastructure have typically had a degree of separation. Michael Osterman discusses some of the emerging (or merging as the case may be) threats to corporate networks posed by the implementation of unified communications in this NetworkWorld article.
