CallKnowing Announces Security Monitoring and Intrusion Detection for Voice Networks

Share Article

With corporate security as a top priority, companies invest millions in sophisticated firewalls and intrusion detection systems for their data networks. But what about voice networks? With CallKnowingÂ?s browser-based Intrusion Detection reports, companies can monitor and protect legacy PBX and voice mail telecommunications systems, as well as PC-based VoIP systems, from potentially devastating malicious or inadvertent intrusion.

CallKnowing LLC today announced the general availability of their latest browser-based monitoring and reporting service, Intrusion Detection for telecommunications networks. The service distributes daily reports documenting suspicious activities on voice networks with installed PBX equipment, allowing companies to quickly respond to potentially devastating hacking and fraud attempts.

While they are the heart of any telecommunications network, traditional PBX and voice mail systems rarely provide logs of system changes or uncharacteristic activity occurring on the voice network. Unauthorized changes to stations, failed access attempts, excessive outcalling from voice mail and unusual trunk activity could all be indications of attempted or actual intrusion. The problem is becoming so widespread that the Department of Homeland Security and the FBI recently issued a bulletin recommending that companies with PBX systems implement strict security measures including continuous auditing of the network to detect unauthorized activity.    

“The truth is that every PBX is connected to other PBXs, and increasingly, to switches, routers and gateways between voice and data networks,” said Roger Anderson, President and founder of CallKnowing. “This convergence only expands the avenues of access to hackers - leaving the company open to expensive theft of services as well as theft of information, vandalism and espionage.”

The solution is a combination of technology, monitoring, and awareness. CallKnowing’s daily electronic reports enable continuous monitoring and auditing of telecommunications devices and databases, creating an early warning system of problems for both legacy PBX and TCP/IP networks. The system tracks the PBX’s configuration and notifies administrators of any changes, evaluates IP-connected devices for hacking vulnerabilities, and performs meticulous scans of all possible TCP and UDP ports. Results are distributed daily in an easy-to-read format via email to customer-defined distribution lists. The system can be customized to adhere to company-specific security policies and requirements.

“The CallKnowing Intrusion Detection service provides peace of mind by performing comprehensive vulnerability assessments on our network. If something changes, CallKnowing finds it,” said Jon Moeller, Director of Web Publishing for Sony Pictures Entertainment. “We have hundreds of thousands of potential doors that can be opened for attacks. It might take us weeks to compile the information they provide each day – by which time, the damage would be done.”
