In this Black Hills Information Security webcast John breakdowns why he hates threat intelligence... Again...
But, he breaks down some of the cool new projects that are focusing on durable threat intelligence. This is key, because many intel feeds are nothing more than domains, hashes and IP addresses. However, with durable threat intel we see attack techniques that are highly effective, yet are not as easy to block.
For example, application allow listing abuse, connection profiles (RITA!), PowerShell encoding are all examples of detects you can use that are not specific to a point in time attack methodology.
John also shares some very cool open source projects that are approaching attacks in this way using ELK.
