Red Team vs Blue Team: Which Is the Best Choice for You?

Red Team vs Blue Team Which Is the Best Choice for You

A fiery debate in cyber security is red team vs blue team. Which is better and which is the right choice for you? 

The red team focuses on assessing an organization's security by simulating real-world attacks. They attack organizations to uncover vulnerabilities and weak security controls. A blue team focuses on defending an organization against cyber attacks. They build security controls, patch vulnerabilities, detect threats, and respond to incidents. 

The path you choose to go down is your choice. This article will compare and contrast the two teams, so you clearly understand what they do, the tools they use, and the skills and qualifications required to fulfill the roles that make up each team. 

Let’s begin by defining what red and blue teams are responsible for and their key objectives.

What Are Red and Blue Teams?

Cyber security can be split into two teams. The red team performs offensive operations against an organization, and the blue team is responsible for protecting an organization’s systems.

Red Team

The red team is responsible for testing security controls and uncovering flaws by attacking IT systems. This could involve testing a specific web application for common vulnerabilities or simulating a real-world cyber-attack against a network. They try to uncover vulnerabilities by exploiting systems and then report these vulnerabilities so they can be fixed before black hat hackers exploit them.

The objectives and responsibilities of a red team are:

  • Assess an organization's security effectiveness by identifying vulnerabilities that an attacker can exploit. 
  • Validate if security controls work as expected.
  • Simulate a real-world cyber-attack.
  • Test the detection and incident response capabilities of the client organization.
  • Validate the ability of the people, processes, and technology to prevent a real-world cyber-attack.
  • Provide recommendations on how to remediate vulnerabilities and security gaps.
  • Collaborate with the blue team in security exercises as part of the purple team.

Blue Team

The blue team is responsible for protecting systems. They implement defensive measures to protect against cyber attacks, monitor these systems, and respond to emerging threats. 

This team patches vulnerabilities, detects threats, and responds to incidents to keep an organization safe. They are the defenders who protect an organization's critical assets 24/7 and are the team that comes to mind for most people when they think of a cyber security team.

The objectives and responsibilities of a blue team are:

  • Provide security monitoring and detection for an organization across its systems, networks, and applications. 
  • Investigate, contain, and respond to cyber security incidents.
  • Manage the security infrastructure of an organization.
  • Provide vulnerability management for an organization.
  • Raise security awareness by educating and training employees.
  • Collaborate with the red team in security exercises as part of the purple team.

Tools and Techniques

Both teams will use various tools and techniques to aid them in their activities to be effective at their roles. Each team also shares some common tools with the other, which can be used to attack or defend systems.

Overview of Common Tools

Red and blue teams often use the same cyber security tools to attack and defend. These common tools are usually the ones that provide information about networks, systems, and applications. The red team uses this information to find vulnerabilities to exploit, whereas the blue team will use this information to identify security gaps that need patched.

Tools used by the red team and blue team:

Although these teams have some tools in common, they also have their own sets of tools that they will utilize to attack and defend systems. Let’s take a look at those tools.

Red Team

To provide a comprehensive security assessment, red teams will use a penetration testing methodology or framework to thoroughly test an organization's security. 

A typical penetration test will follow eight phases during an engagement:

  1. Planning and Preparation 
  2. Reconnaissance
  3. Scanning and Enumeration
  4. Vulnerability Assessment
  5. Exploitation
  6. Post-Exploitation
  7. Reporting
  8. Remediation and Follow-up
Pentration Tests

Along with a methodology, a red team will use tools to help them with their testing. These tools allow them to automate time-consuming tasks and perform offensive operations more efficiently.

Tools used by the red team:

More details on the tools used by red teams can be found in these articles:

Blue Team

A blue team is responsible for defending systems. To do this effectively, they require comprehensive logs from the systems they must protect. These logs allow blue team members to monitor their systems, trigger alerts if malicious activity is detected, and respond to incidents effectively. These logs are collected and pushed to a Security Incident and Event Management (SIEM) system, where they can be analyzed. 

Additionally, a large part of a blue team's role is investigating the detected malicious activity. This requires tools to analyze computer forensics and malware, manage investigations, and perform reverse engineering when necessary.

Tools used by the blue team:

Skills and Qualifications

Now you have a firm understanding of what makes up a red team and a blue team, along with an idea about the tools each team uses, let’s look at the skills and qualifications required to become a member of each team.

Shared Skills and Qualifications

Both teams require fundamental skills that any cyber security professional needs. These include both technical skills and soft skills.

Technical SkillsSoft Skills
Computer networkingCommunication
