Use this tool to identify files on your system that may have Social Security Numbers (SSNs) or Credit Card Numbers (CCNs). 3) Spider (Windows) (Linux) Spider’s purpose is to identify files that may contain confidential data. It scans a collection of files, searching for patterns of numbers or letters that resemble Social Security numbers or credit card numbers (additional search patterns can be created using Unix regular expressions). 4) Tenable’s Ron Gula’s blog using Nessus to find Senstive Data: Detecting Credit Cards, SSNs and other Sensitive Data at rest with Nessus 5) Snort - using the Bleeding EdgeEmerging Threat Snort rules, (see BLEEDING-EDGE Credit Card Number Detected ET POLICY Credit Card Number Detected in Clear) You might be using snort as and IDS - or using a product or appliance that uses it as its engine.
