Today, the risk of cyberattacks has increased. An organization may lose important data to a group of hackers. Antivirus is no longer sufficient to keep the hackers away. Numerous types of attacks can steal the organization's important data. Thus organizations must increase their cybersecurity to protect the data from vulnerabilities.

When cybersecurity is discussed, we often hear the terms “red team” and “blue team”. The red team and blue team are used to protect the organization from various harmful attacks.

In this article, we discuss the differences between the red team and the blue team.

To brush up on your knowledge of cyber attacks,  you can read the article threats to information security on Coding Ninjas Studio.

Before we see the difference between them, let us first understand the meaning of the red team and the blue team.

What is a Red Team?

Red teams penetrate various systems and determine their security levels. Red teams find, prevent, and eradicate security flaws and show the organization the weaknesses of their cybersecurity by taking the position of an attacker. Whether internal or external, Red Teams are entrusted with evaluating the success of a security programme by imitating as closely as possible the tools and techniques of potential attackers. It entails the pursuit of one or more objectives, usually in a campaign, and is similar to, but not identical to, penetration testing. Pen testing or ethical hacking are other terms for penetration testing. It refers to the deliberate launch of simulated cyberattacks to find exploitable flaws in computer systems, networks, websites, and applications.

The tools and techniques which the red team uses are:

  • Phishing
  • Penetration testing
  • Social engineering
  • Network penetration testing
  • Application penetration testing
  • Web app scanning
  • Black box scanning

Red Teams test for vulnerabilities as well as they do campaigns that constantly run for an extended period.

What is a Blue team?

Blue teams can be termed as the company's defenders. Blue Teams, or internal security teams, protect against real attacks and Red Teams. Most security operations teams lack the mindset of constant vigilance against assault, which is a real Blue Team's goal. As a result, Blue Teams should be differentiated from ordinary security teams in most companies. A blue team also tries to identify flaws in a cyber system of an organization. The difference is that the blue team tries to defend the cyber system when the red team attacks.

The blue team uses various techniques to defend the organization. 

Some of them are:

  • Perform DNS searching
  • Spots unusual activity in the network
  • Performs DDOS(distributed denial of service) attack
  • Performs footprint analysis
  • Identify threats and risks in the cyber system

How do the red team and the blue team work together?

The red team tries to penetrate the cybersecurity and break into the system. The blue team tries to protect the cyber network at the same time. The blue team then further attacks the organization using social engineering and other attacks. The blue team again tries to protect against this attack of the blue team. The red team aims to expose the vulnerabilities of the system.

The organization get benefitted from both of them. Both of them inform the organization about the vulnerabilities of the network.

Differences Between the Red Team and the Blue Team


1. What does a Red team do?

The red team shows the organization the flaws of their system by taking the position of an attacker.

2. What is a blue team?

Blue Team defends the organization from the attacks of both real attackers and the Red Teams. The blue team tries to protect the system from attacks continuously.

3. What techniques does the blue team use?

The blue team performs DNS searching, DDOS attack, footprint analysis. It constantly tries to identify the threats to the cyber system of the organization.

4. What techniques does the red team use?

The tools and techniques that the red team uses are phishing, penetration testing, social engineering etc. They try to attack the organization and find the vulnerabilities in the organization.

5. What are the major differences between the red and blue teams?

Red teams attack the organization to gather its weaknesses and thus tell the organization about the vulnerabilities. The blue team defends the organization and uses various tools to strengthen the organization.
