Synopsis: 

Show ContentSpoiler:

Evasion Techniques and Breaching Defenses (PEN-300) is an advanced penetration testing course. It builds on the knowledge and techniques taught in Penetration Testing with Kali Linux, teaching students to perform advanced penetration tests against mature organizations with an established security function.
As a general rule, it will not specifically deal with the act of evading a blue team but rather focus on bypassing security mechanisms that are designed to block attacks. This course is one of the replacements for the Cracking the Perimeter (CTP) course — retired October 15, 2020.
