The NIST has released a public draft of Federal Information Processing Standard (FIPS) 199. The standards call for government systems to be categorized based on the information they contain and the sensitivity of that information or the risk posed should that information be compromised.

FISMA tasked NIST to develop:
Standards to be used by Federal agencies to categorize information and information systems based
on the objectives of providing appropriate levels of information security according to a range of
risk levels;
Guidelines recommending the types of information and information systems to be included in
each category; and
Minimum information security requirements, (i.e., management, operational, and technical
security controls), for information and information systems in each such category.
The draft will be circulated for comment for 90 days before comments will be assessed and the final document will be produced.
