Prior knowledge for OSED | EXP-301 (Pre Guide)

This is a repository of notes and material that I consider necessary in advance to opt for the course and the OSED certification (Windows User Mode Exploit Development)

This guide was born as a result of my interest in obtaining previous knowledge before eventuring the preparation course for the certification exam OSED.

I am currently in the process of preparing for certification (I will update this repository) :D
