Implementation Groups (IGs) are the recommended guidance to prioritize implementation of the CIS Critical Security Controls (CIS Controls).
IG3 is comprised of an additional 23 Safeguards. It builds upon the Safeguards identified in IG1 (56) and IG2 (74) totaling the 153 Safeguards in CIS Controls v8.
An IG3 enterprise commonly employs security experts that specialize in the different facets of cybersecurity (e.g., risk management, penetration testing, application security). IG3 assets and data contain sensitive information or functions that are subject to regulatory and compliance oversight. An IG3 enterprise must address availability of services and the confidentiality and integrity of sensitive data. Successful attacks can cause significant harm to the public welfare.
Safeguards selected for IG3 must abate targeted attacks from a sophisticated adversary and reduce the impact of zero-day attacks.
Below is a list of the CIS Controls in v8, and how many Safeguards in each are applicable to each Implementation Group.
