What are the red team and the blue team in cybersecurity?

When talking about computer security, two important teams come into play: the Red Team and the Blue Team. These are terms used in military training, but over time, they have transcended the field of cybersecurity.

These names refer to the equipment that many large organizations have to defend themselves against cyber attacks such as computer worms or viruses. Normally these attacks seek to take over confidential data and private information of companies.

To avoid this, there are the Red Team and the Blue Team. In this article, you will learn the functions of each of them and what their importance is.

What is a Red Team in cybersecurity

The Red Team is in charge of offensive security. For it, emulates possible procedures and techniques that malicious actors or attackers could implement. Its objective is to explore possible security vulnerabilities in systems or applications.

In this team, professionals try to overcome security controls by imitating threat scenarios that an organization could face and analyze the type of security that exists from the attackers’ point of view. Therefore, it can be said that they are specialists in attack systems.

They typically spend more time planning an attack than actually putting it into action. When they perform these simulated attacks, they then provide constructive recommendations on how an organization can improve its cybersecurity.

The Red Team, therefore, analyzes the ability of an organization to protect its critical assets and is a way to train the Blue Team.

What is a Blue Team in computer security?

The Blue Team carries out defensive security. It is responsible for defending organizations from possible attacks.

Unlike the red team, it is made up of security professionals who have the main task of protect an organization’s critical assets from any type of threat. Therefore, its objective is to “strengthen the defense.”

As it does? First of all, collect data to make an assessment of possible risks. That is, critical assets are first identified to see their importance and the impact that their absence could have.

To then reinforce the system using various techniques: from informing and educating staff in the necessary procedures, to using stricter password and security policies.

In this way, the Blue Team carries out continuous surveillance, in addition to constantly improving security and carrying out response tasks in case there is a problem.

That is why both the red and blue teams provide a complete security solution with their respective functions.
