Introduction to Cyber Security

Cyber Security is a vast field, many things are vulnerable to Cyber Attacks. However, on the internet, there are generally two fields, Network Security and Software Security. Network Security is the Security mechanism of Computer Networking and Cloud Technologies while Software Security is the Security mechanism of Softwares like Web Applications and Mobile. Generally, there are two types of Security teams, Red Team who are responsible for testing the security of a system and Blue Team who are responsible for defending it. The people who are doing both of them is called Purple Team.

There are several methods to secure a system, one of them is Penetration Testing (Red Team), which is to test the security of a system by actually hacking it. Another one is implementing security on the system with Security Engineering (Blue Team), yet another one is implementing Secure Coding Practices (Software Developers).
