IOS Theft and Telephony: Something New to Worry About
VOIP on managed networks won't be the first of hackers' targets, but it will be hurt if major IP carriers are attacked.I assured readers with my first column that my job here is to report on VOIP, not to praise it. Which is why Im just as eager as anyone to get a read on the potential seriousness of the Cisco IOS source code theft and its implications for the reliability of IP-based communications. As reported by a Russian security Web site and confirmed by Cisco, hackers broke into the switching and routing giants network and stole 800MB of source code for IOS 12.3 and 12.3t. The IOS 12.3 operating system powers Ciscos networking product suite, including routers used in homes and small businesses and the 7000 series that makes up the Internet backbone. All of Ciscos infrastructure productsswitches and routersare exposed. I wrote five days ago that an IP voice application inherits the security of the data network. If someone can hack into your network infrastructure (typically composed of a Cisco router and switches) and bring it down, obviously, thats not a good inheritance. If your voice traffic is using voice over IP, it relies on the network infrastructure being robust. Whether its Ciscos Call Manager or anyone elses IP PBX youre using, a router ם and very likely thats a Cisco router fronts the system.
