Let's talk about STIX, TAXII, and threat intelligence

In terms of collaboration, Structured Threat Information eXpression (STIX) and Trusted Automated eXchange of Indicator Information (TAXII) represent a revolution in the security industry. These protocols transformed the field of threat intelligence from a fragmented collection of information to a unified standard for information sharing. In this blog, I will examine this transition and how it came about.

Introducing Elastic Machine Learning Data Visualizer

Automatically Model the Complexity of the Real World. Skip defining rules, specifying thresholds, or manually building out statistical models. Our machine learning features make it easy to start identifying anomalies. Just describe the data you're interested analyzing (requests per second) and what other properties might influence it (server, IP, username), and that's it.

Of course we can only mitigate some PowerShell attacks if we have a trace, so going forward I am assuming that you followed part 1 of this series and enabled: Module Logging, Script Block Logging, Security Process Tracking (4688/4689)

Imagine someone getting the seemingly innocent ability to run a couple of commands on a machine on your network WITHOUT installing any new software, but those commands resulting in a reverse shell running on that same machine – giving the intruder a convenient outpost in your network. Now stretch your imagination even further and pretend that all of this happens without leaving any unusual traces in logs – leaving you completely in the dark.
