The Recipe for Threat Intelligence = Context + Attribution + Action

Monitoring your environment for nefarious traffic assumes that you know what those nefarious folks are doing, what “it” looks like, and how to find this activity across your critical infrastructure in the cloud and on-premises. The “bread crumbs” that these adversaries leave are usually of the same sort: IP addresses, host and domain names, email addresses, filenames, and file hashes.

With this amount of information, you can’t actually get that far. As a SOC analyst conducting an in-depth investigation, you need to be able to attribute these bread crumbs to specific adversaries, understand their methods, know their tools, recognize their infrastructure, and then build countermeasures for preventing attacks from them.

Some may refer to these “bread crumbs” or indicators (IOCs = indicators of compromise) as threat intelligence. This is far from the truth. On their own, without any context, they exist only as artifacts or clues.
