I"m working on Network Security right now. Planning to do my Cyber Security later in 2021.
first security certification is CompTIA Security + certification and establishes the core knowledge. On the subject of information security are well-known institutions (SANS, Offensive-Security, EC-Council) that each offer their own Roadmap.
EC-Council, for example, summarizes this course to information security
This is a roadmap that helps you get into the information security.
Offensive-Security, a company active in the field of information security, has also introduced its own Roadmap. (Courses that have more audience are PWK (OSCP) and WIfu (OSWP), the first is the network penetration test and the second is the wireless penetration test.
SANS Company, which is the best institute in the field of information security in the world, has also provided a better and more comprehensive Roadmap, which if you decide to enter the world of security professionally and work professionally, be sure to start working from SANS courses.
The course that specializes in network penetration testing is the SANS SEC560 Network Penetration Testing and Ethical Hacking course, which is also available on the website as a video, and instead of passing several network penetration testing courses, you can pass this course, which is more complete and accurate.
