FIPS199 Categorizer is a simple utility for allowing you to define systems and assign categories based on the NIST FIPS PUB 199 impact descriptions by Security Objective. The FIPS199 Categorizer will show you the final FIPS199 Security Categorization for the system based on your selections.
Your final result of Low, Moderate, or High will dictate which security controls must be implemented for that system.
Finally, FIPS199 Categorizer lets you review previously categorized systems and delete them as you see fit.
