Integrating CTI with purple teaming
As we saw in Chapter 2, Purple Teaming – a Generic Approach and a New Model, the purple teaming process starts by selecting and preparing TTPs, but during that chapter, we only provided a broad overview.
Based on the knowledge we have gained in this chapter, we will try to apply the CTI process to our purple teaming exercise. As we've seen, we must start by defining the intelligence requirements for our purple teaming exercise.
Now, depending on the type of exercise and the maturity level of our purple teaming program, there are two potential intelligence requirements.
The first one is quite obvious – the CTI must identify, select, and collect information about threat actors and campaigns relevant to our organization. Then, TTPs must be extracted to form an emulation plan so that we are in a position to replay them by performing adversary emulation. This is in order to test our security controls against them.
The second...
