VECTR for Purple Team Engagements

Introduction As anyone who has conducted a lengthy purple team engagement will tell you, logging and centralising the huge amount of data from these engagements can quickly become overwhelming. In the past we have seen attempts to use generic productivity software, such as Sharepoint, to attempt to track the huge number of activities and logs generated by both the red and blue teams. However, as you can imagine, shoehorning large quantities of engagement data from two teams with different operating procedures into a single application not built for this purpose can be…tricky. As purple team enthusiasts, we believe we have found a better solution to this problem, and sharing that with the wider security community is the purpose of this blog post. We also want to share some guidance when using this framework to help others avoid making the mistakes we have in the past. What is VECTR?...

Implementation and Dynamic Generation for Tasks in Apache Airflow

I recently worked on a project focused on log anomaly detection using manageable machine learning pipelines. The pipelines mainly include data collection --- feature extraction --- feature engineering --- detection/prediction --- updating (maintenance).  It’s important to have a solid UI to manage the pipelines so I can easily review the chain of pipelines. After much research, I found many...
