ICD 503 Compliance

FISMA Compliance for the Intelligence Community

 

DCID 6/3

The United States Intelligence Community (IC) has a unique set of information security requirements, requiring the highest levels of confidentiality and integrity, coupled with the need to manage access to secure compartmented information based on both clearance level and an established need to know.  These requirements have led to the establishment of a common InfoSec policy for all member agencies. Dating back to the 1970s, Director of Central Intelligence Directives (DCIDs) were the primary instrument for defining IC-wide policies. DCID 6/3, “Protecting Sensitive Compartmented Information Within Information Systems,” defined a series of policies related to information security. The DCID 6/3 implementation manual specifically defined a series of five “protection levels,” each of which delineated the audit requirements for systems operating at increasing levels of confidentiality.

ICD 503

In 2008, the Director of National Intelligence signed IC Directive 503, “Intelligence Community Information Technology Systems Security Risk Management, Certification and Accreditation.” ICD 503 replaced DCID 6/3, and is today the relevant guidance for the risk management and certification of information systems across the IC. This standard specifically requires the IC to use NIST or CNSS standards for security certification assessment and testing. CNSS Policy No. 22, “Policy on Information Assurance Risk Management for National Security Systems,” specifically points to FISMA for security audit controls, reinforcing the move to a NIST/FIPS based approach to information security across the IC.
