Consensus Audit Guidelines (CAG) | SANS | 20 Critical Security Controls | Overview | the Importance of Information Security Policies and Procedures
51. What is the Consensus Audit Guidelines (CAG) | 20 Critical Security Controls and why are information security policies and procedures so important today, and do you offer comprehensive I.T. security documentation?
The Consensus Audit Guidelines (CAG), also known as the 20 Critical Security Controls, is a publication of best practices relating to computer security that essentially encompasses twenty (20) core controls. Today’s growing cyber security threats are posing serious challenges for organizations regarding the confidentiality, integrity, and availability (CIA) of their networks, ultimately requiring comprehensive measures for protecting critical assets and infrastructure. What’s interesting to note about the 20 Critical Security Controls is the formation itself, which came about due to a collaborative effort amongst a number of well-known entities, such as United States government agencies, information security forensics experts, and others.
The result has been a set of controls viewed very favorably by the information security industry, thus setting the tone for a best practices approach that many organizations - both from a governmental and private sector perspective – actually adhere to. SANS, one of the world’s most well-known and respected information security research and educational institutions, publishes and updates the 20 Critical Security Controls (via versions), which can be found at http://www.sans.org/

Security Policies | Essential to the 20 Critical Security Controls
When looking at these twenty (20) control areas – which have changed only slightly from one version to another – one important element is very clear: adherence to the stated best practices concepts requires a comprehensive amount of operational, business specific, and information security policies and procedures, no question about it. How can any framework be considered a true and viable working model without formalized and well-documented policies and procedures?
The FLANK21 set of operational and information security templates from FLANK is your answer, as organizations will receive literally hundreds of essential policies, procedures, forms, checklists, templates, provisioning and hardening documents – and more.
