This whitepaper offers a deep-dive into the diminished value of Indicators of Compromise (IOCs) for early detection, defining and operationalizing Indicators of Behavior by establishing a common extensible language for their expression, a case study for leveraging Indicators of Behavior (IOBs) based on the SolarWinds attacks and more.
Today’s security model produces an endless stream of uncorrelated alerts, the majority of which are either false positives or merely offer glimpses of a larger attack sequence. This means analysts have to manually triage, investigate and then correlate against other alerts—a process that simply cannot scale effectively to keep organizations and their clients secure.
There is a better way, but it requires a fundamental change in how we approach security by moving away from the labor intensive, inefficient and ineffective alert-centric model in favor of a more effective, highly efficient Operation-Centric approach.
An Operation-Centric approach leverages Indicators of Behavior and enables security operations to dynamically detect and predictively respond more swiftly than attackers can modify and adjust their tactics to circumvent defenses, which is key to finally reversing the adversary advantage and returning the high ground to the Defenders.
