A month ago we, Ruben and Marcus, released the first version of DeTT&CT. It was created at the Cyber Defence Centre of Rabobank, and built atop of MITRE ATT&CK. DeTT&CT stands for: DEtect Tactics, Techniques & Combat Threats. Today we released version 1.1, which contains multiple improvements: changelog. Most changes are related to additional functionality to allow more detailed administration of your visibility and detection.

By creating DeTT&CT we aim to assist blue teams using ATT&CK to score and compare data log source quality, visibility coverage, detection coverage and threat actor behaviours. All of which can help, in different ways, to get more resilient against attacks targeting your organisation.

In this blog we start off with an introduction on ATT&CK and continue with how DeTT&CT can be used within your organisation. Detailed information about DeTT&CT and how it can be used, is documented on the GitHub Wiki pages. Therefore, the explanation we give in this blog will be high-level.
