Tapping into VoIP

ManTech International Corp., Fairfax, Va., released version 5.0 of its NetWitness wiretap tool. The new version includes better analytical features and increased abilities to monitor voice over IP traffic.

The company stressed that the days of listening in on phone calls are in the past. As criminals and terrorists make better use of instant messaging, e-mail and online Web logs, the government needs tools for monitoring network traffic.

NetWitness 5.0 collects and analyzes select network data so it can be reviewed. It does not copy all data the way a network analysis tool might. The software also includes an integrated GeoLookup service that allows investigators to locate Internet-based targets geographically.
