Abstract

Cyber defenders frequently rely on Indicators of Compromise (IoCs) toidentify, trace, and block malicious activity in networks or onendpoints. This document reviews the fundamentals, opportunities,operational limitations, and recommendations for IoC use. Ithighlights the need for IoCs to be detectable in implementations ofInternet protocols, tools, and technologies -- both for the IoCs'initial discovery and their use in detection -- and provides afoundation for approaches to operational challenges in networksecurity.
