# attack-eval-scoring

This project represented my attempts at analyzing the results of round 1 of the MITRE Enterprise ATT&CK Evaluation. With the release of round 2 results, please check out my new project:
https://github.com/joshzelonis/EnterpriseAPT29Eval

For my initial blog post on the subject, check out:
https://go.forrester.com/blogs/measuring-vendor-efficacy-using-the-mitre-attck-evaluation/

## simple_score.py
In parsing the results, I found 56 ATT&CK techniques were measured with 136 procedures for doing so. This is a quick script for applying the scale on a procedure (or per step) basis. There were many instances where there were multiple detections for a single procedure/step which would skew any counting method that did not take this into effect.

## coverage.py
This script generates two key metrics for understanding vendor performance. The first of which is a coverage score which gives insight into the percentage of ATT&CK techniques the solution was able to generate any type of detection against. This can be viewed as a high water mark for how the product could be used to generate detections. The second metric is a correlation metric which is the percentage of detections that had a tainted modifier. This is useful for understanding how the product reduces work for SOC analysts.

## kill_chain_analysis.py
There were 10 different stages of attack measured from initial compromise to execution of persistence across two scenarios. One may argue that the most critical capability is being able to alert on an aversary at each stage of an intrusion. This script analyzes and breaks out how each vendor performed at each stage of these scenarios on the same 1-3-5 scale used by simple_score.py

## total_misses.py
Based on the Endgame Blog (https://www.endgame.com/blog/executive-blog/heres-why-we-cant-have-nice-things), we see that there's a number of situations where a product does have functionality that an investigator could use to surface some information about an event that the methodology did not recognize. It's not immediately obvious how to generate the numbers that correspond to the blog so I'm using the Endgame numbers here with a code comment so you can see how, with minor modification, you can obtain the scores that more strictly correspond to MITRE's evaluation.

## query_attack.py
In analyzing vendor performance, I frequently wanted to do quick lookups against techniques or procedures to see how the vendors performed in a side by side basis such as `$ python query_attack.py -p 2.A.1` or `$ python query_attack.py -t T1016`. Also, I found myself wanting to do string searches against other fields in the evaluation reports, so I've enabled case insensitive string searching using regex against many of the fields in the reports. Want to know which procedures leveraged the ipconfig command? `$ python query_attack.py -s ipconfig` Want to know which delayed detections Microsoft had? `$ python query_attack.py -s delayed microsoft` Want to know which detections OverWatch sent an email for? `$ python query_attack.py -s "overwatch .* email"` If you really want to go nuts you can use all of these flags together to specifically see the tainted detection CounterTack had on technique T1055 in step 5.A.2 with `$ python query_attack.py -s tainted -p 5.A.2 -t T1055 countertack`. You get the idea.
