The Committee on National Security Systems (CNSS) Library contains those issuances permitted on the Internet that address information assurance (IA) issues. The Library is divided into several categories: Policies, Directives, Instructions, and Advisory Memoranda, as well as offers an Index of all the documents published by the CNSS Secretariat.
You will note that some documents are CNSS documents and others appear as NSTISS documents. The CNSS was formerly known as the National Security Telecommunications Information Systems Security Committee (NSTISSC). Documents created under the old title still reflect the NSTISS numbering system.
All UNCLASSIFIED issuances, made available for download from the CNSS web site, are in Portable Document Format (PDF). PDF files require the free Adobe Acrobat Reader. Adobe also provides free PDF tools for the visually impaired.
