Hardware Protocol Analyzers

www.info-savvy.com

A hardware protocol analyzer may be a device that interprets traffic passing over a network. It captures signals without altering the traffic segment. Its purpose is to monitor network usage and identify malicious network traffic generated by hacking software installed on the network.

It captures a data packet, decodes it, and analyzes its content consistent with predetermined rules. It allows an attacker to see the individual data bytes of every packet passing through the network.

Lawful Interception

Lawful interception refers to legally intercepting data communication between two endpoints for surveillance on the normal telecommunications, VoIP, data, and multi service networks. Lawful interception (LI) obtains data from a communication network for analysis or evidence; this is often useful in activities like infrastructure management and protection, also as cyber securityrelated issues. www.info-savvy.com
