voip architecture
Cisco Systems has disclosed that a core component of its enterprise VOIP system is vulnerable to several serious security flaws. The flaws could allow remote attackers to compromise a company's VOIP network, VoIP Main Page
redirect or listen in on calls and carry out other nastiness, according to Cisco and Internet Security Systems (ISS), which discovered the flaws. While the bugs voip solution architecture haven't yet been exploited, they represent one of the most high-profile security scares in enterprise
IP telephony to date. Enterprises are moving quickly to shift VoIP Main Page
to IP-based telephone networks, with Gartner predicting that by 2007, 97 percent of new enterprise phone systems installed in North America will be either VOIP or hybrid. Cisco leads the market VoIP Main Page
at the moment architecture london solution voip by a wide margin, with a 42 percent share in North America, followed by Avaya with 14 percent, 3Com with 11 percent and Nortel with 9 percent, according to Gartner's research. Cisco reported five separate security bugs in CallManager, the call- processing component of VoIP Main Page
the Cisco IP telephony system. The most
serious is in the aupair.exe service, which could architecture london voip allow a remote attacker to cause a buffer overflow and execute malicious code. Aupair.exe can't be disabled for normal CallManager use, Cisco VoIP Main Page
said. CallManager is vulnerable in its default configuration, and an attack could be carried out without the need for prior authentication, ISS said. An attacker may be able to redirect calls or perform eavesdropping as a result
voip network architecture of this compromise. Successful exploitation of this VoIP Main Page
vulnerability could be used to gain unauthorized access to networks and machines with Cisco VOIP products, the security firm said in an advisory. Cisco has released patches for the affected versions of CallManager, including 3.3 and earlier, 4.0 and 4.1. Its advisory and patching instructions are on Cisco's Web site.
