The bad guys are trying to steal and mess with a company’s important stuff online. So, the company needs to protect its important information from being stolen or messed up. They have special teams called Red Team and Blue Team to do this. The Red Team pretends to be the bad guys and finds weak spots so they can be fixed. The Blue Team defends the company from these pretend attacks. This is really important because it stops real bad guys from stealing important things like customer info, trade secrets, or private business messages. Today we’ll discuss Red team and Blue team. However there are also other teams enhancing cybersecurity everyday:

The red team plays offensive role. The roles of red team consist of:

The blue team plays defensive role. The role of blue team consists of:

Red and blue team should keep communicating with each other, it is an important factor.

Likewise, blue team will do the same, they will share the latest technologies finding with red team to improve security.
