  • Enterprise Linux Security Episode 58 – Tales from the Red Team

    Tasks that penetration testers and security analysis perform in order to expose security weaknesses may seem like a mysterious and complicated art. Most of the time, these tasks are considered “secret sauce” and unless you work for a red team, you may not be aware of what it may look like while someone attempts to gain access from the outside. In this episode, Jay and Joao discuss a report released by CISA, that provides a very detailed account at what goes into this type of work. This report is definitely a must-read, and this episode is a must-listen!
