Red Team vs Blue Team: Meet the Information Security Teams

Red team vs Blue team: if you work in information security, you've likely heard of these two teams. Much like in a football team, where you have both offense and defense, cybersecurity teams operate similarly.

With specific responsibilities, these two teams work together to maintain cybersecurity and protect companies from attacks such as malware, ransomware, and more.

By helping to identify security issues and enhance security maturity in organizations, Red Team and Blue Team are essential components of an information security strategy.

What is the Red Team?

The Red Team functions as the offensive team in our football metaphor. However, these ethical hackers work for, not against, companies.

To do this, Red Team professionals understand current market threats and use their skills to conduct controlled attacks and identify potential vulnerabilities. They help in discovering weaknesses and thereby assist in eliminating them.

Techniques commonly used by the Red Team include:

• Penetration Testing (Pentest): Specialists attempt to gain access to a system.
• Social Engineering: The Red Team tries to persuade or deceive company members into revealing personal data or other information.
• Phishing: This involves sending seemingly legitimate emails that trick recipients into performing actions like logging into fake websites. The goal of such attacks, when not simulated, is to steal credentials.
• Copying and Cloning Access Cards: To restricted areas.

Since all these simulated attacks aim to find vulnerabilities and improve security, Red Team professionals must write reports after their attacks.

These bug reports should include details about the techniques used, the specific attacks conducted, their success or failure, and recommendations on how the company can enhance the security of its systems against future threats.

What is the Blue Team?

Continuing with the football metaphor, the Blue Team functions as the defensive team. This means that these professionals create defense strategies for the company.

By developing strategies to enhance defenses, the Blue Team modifies and strengthens network protection mechanisms.

Like the Red Team, the Blue Team also needs a good understanding of potential threats to systems. This enables them to address vulnerabilities and overhaul the entire defense infrastructure.

Common responsibilities of the Blue Team include:

• Monitoring networks, systems, and devices within the company.
• Detecting, mitigating, and eradicating cybersecurity threats and attacks.
• Analyzing data.
• Assisting and guiding the proper storage of data.
• Continuously working to improve security standards.

The main advantage of a Blue Team is maintaining an up-to-date security system, as simulated attacks from the Red Team help the team anticipate vulnerabilities.

Additionally, Blue Team professionals:

• Create, configure, and apply firewall rules.
• Define and implement device and user access controls, preventing unauthorized access.
• Keep corporate systems patched and updated.
• Conduct reverse engineering of cyber attacks.
• Perform DDoS defense testing.
• Develop rapid remediation policies to ensure systems recover securely and quickly from incidents.

Red Team vs Blue Team: Can They Work Together?

While understanding the difference between the Red Team and the Blue Team is important, the two teams can and should work together! For a company to be as protected as possible, it's ideal to have both teams collaborating to find and fix vulnerabilities.

After all, the Red Team uses its attack tactics and skills to test the Blue Team's defenses, working in tandem.

What About the Purple Team?

Though not as well-known and established as the Red and Blue Teams, the Purple Team has emerged to bridge the gap between them.

Just as the colors red and blue mix to form purple, the combination of Red and Blue Teams creates the Purple Team. This team ensures that both teams work effectively together to further enhance the company's security.

The Purple Team can take two forms:

1. External or Internal Purple Team: Comprising security professionals from outside or within the company, they perform both Red and Blue Team functions. An organization might hire a Purple Team to conduct a comprehensive audit of its security systems, with the Purple Team splitting into Red and Blue sub-teams for attack and defense testing. This can also apply to an internal team.
2. Mediator Purple Team: This team is hired or created internally to facilitate the relationship between Red and Blue Teams. Since activities between the Red Team and Blue Team require significant collaboration to be effective, having a mediator that reviews the process, promotes communication, and helps both teams achieve their goals is beneficial.
