Organizations need to proactively identify and resolve their vulnerabilities with the increasing sophistication and frequency of cyberattacks. An effective method of doing this is red teaming cyber security, which involves a simulated attack on an organization to test its security measures.

In this article, we’ll define Red Teaming, explain how it works, discuss the difference between the red and blue teams, and explain why organizations must use it in their cyber security strategies.

What is Red Teaming?

In the 1800s, the German army came up with the idea of “red teaming.” Military officials would act out possible battle sequences by playing a board game with terrain pieces and combat tokens. The aim was to ensure the military was better prepared for unpredictable events (called “frictions”) during battle.

Red teaming is a comprehensive approach used in modern cyber security to simulate an attack from a real cybercriminal across multiple layers of security, such as the network, applications, software, and physical security controls. It measures how well an organization can withstand a cyberattack.

The red team comprises a group of skilled experts who act as attackers and use tools and techniques to simulate an attack. By acting out real-world attacks, a Red Team can determine where a company’s defenses, systems, and processes are vulnerable.

What Are the Benefits of Red Teaming?

1. Identifying Vulnerabilities

With red teaming, an organization can identify vulnerabilities that might be missed by regular security assessments or penetration testing. Besides, by simulating a real-world threat, a Red Team can identify gaps in an enterprise’s security posture that real attackers could exploit.

2. Providing Recommendations for Enhancing Security

Red Teams can provide helpful recommendations on enhancing the company’s security based on their findings during the red team exercise. It is more likely that cyberattacks will fail if a company implements these recommendations.

3. Testing Incident Response Plans and Procedures

Red teaming helps companies prepare for the real thing by simulating real-world attacks. This can be handy for businesses, as they can identify areas for improvement in their response plans and ensure they are ready to deal with real cyberattacks.

4. Protecting Sensitive Data

Red teaming can help the organization comply with regulatory requirements and demonstrate diligence in protecting sensitive data. Performing red team exercises demonstrates to clients that your company is actively monitoring and preventing cyber security threats.

5. Building a Culture of Security

To strengthen a company’s security culture, red teams” can raise awareness of cybersecurity risks and inspire workers to take proactive measures. And by demonstrating the potential consequences of a successful cyber attack, red teaming can help employees understand the need to adhere to security policies and procedures.

Red Team Exercise Examples

1. Penetration Testing

In penetration testing, an “ethical hacker” team looks for vulnerabilities in a company’s system, software, or network. The aim is usually to identify weaknesses and offer recommendations to improve security.

2. Physical Security Testing

In a physical security test, the red team tries to access a facility by bypassing physical security controls such as access cards, locks, and security personnel. The test is handy when it comes to helping identify vulnerabilities in physical security measures.

3. Social engineering

In a social engineering exercise, the red team uses manipulation and deception to get sensitive data or access to the system from the employees of the target organization. This test helps identify weaknesses in team member training and awareness programs.

4. Red Team vs. Blue Team Exercise

The exercise involves a simulated attack on a company’s system or network. The red team tries to infiltrate and exfiltrate data; on the other hand, the blue team tries to identify and stop the attack. The test is crucial in identifying weaknesses in detection and response abilities.

5. Cyber Range Exercise

In this exercise, a red team simulates an attack on a company’s network in a controlled setting. The exercise aims to assess the company’s cyber defenses in terms of strategies, technology, and human resources.

6. Tabletop Exercise

In this exercise, the red team and the organization’s management work together to simulate a cyberattack and discuss the best response and mitigation strategies. The exercise helps identify weaknesses in communication and incident response.

Steps to Creating an Effective Red Team

1. Determine the Objectives and Scope of the Red Team.

Determine the scope of the red team exercise, including the processes, systems, and personnel that will be tested. Also, explain what you want to accomplish by conducting this engagement, such as identifying vulnerabilities or testing the security team’s response to a simulated attack.

2. Choose the Team Members.

The team members must have extensive knowledge of security practices, including social engineering, penetration testing, and network security. Also, they should be familiar with the organization’s infrastructure, processes, and employees.

3. Establish Rules of Engagement.

To create an effective red team, you need to determine the rules of engagement, including the techniques, tactics, and procedures that can be used. Also, the boundaries that shouldn’t be crossed and the expected outcomes

4. Conduct Reconnaissance

Do a comprehensive reconnaissance analysis of the company’s infrastructure, processes, and personnel. This can include network scanning, social engineering, and open-source data analysis.

5. Plan the Attack

Based on the reconnaissance data, the red team should plan the attack. This includes identifying the techniques, tactics, procedures, and attack vectors.

6. Execute the Attack

Execute the cyber attack using the planned techniques, tactics, and procedures. The attack aims to identify vulnerabilities and weaknesses in the company’s infrastructure, processes, and personnel.

7. Report Findings

After completing the red team engagement, the team should report their findings to the company’s security personnel. The report should describe the vulnerabilities and weaknesses identified throughout the engagement as well as recommendations for how to address them.

8. Follow Up

Follow up with the company’s security team to ensure that the weaknesses and vulnerabilities identified are remediated.


To summarize, red teaming is an excellent technique to strengthen a company’s security posture and identify vulnerabilities. By following the steps to creating an effective red team, the company’s cybersecurity defenses will improve and be better prepared for potential attacks. Equipping your organization with the red team will be worth it now and in the future, especially with the increasing sophistication and frequency of cyberattacks.

Frequently Asked Questions on Red Teaming Cyber Security

1. What’s the Role of the Red Team?

In a simulation attack, a red team plays the role of the intruder using hacker-like tools and techniques to stay inconspicuous while testing the organization’s defense readiness of the internal security team. The test includes the organization’s vulnerabilities and the security personnel.

2. Can a Red Team Exercise Cause any Issues?

Unlike actual cyberattacks, red team exercises are not designed to cause any issue or disruption. You can be sure that your engagements will be carried out by the rules of engagement and the highest technical, legal, and ethical standards by choosing the right red team service provider.

3. How Long Will it Take to Run a Red Teaming Exercise?

The scope and objectives of a red team exercise determine how long it will take. Usually, a full end-to-end red team engagement takes 1-2 months. On the other hand, a specific scenario-based exercise with a narrower focus can take over 11-18 days. Shorter exercises, especially those designed to simulate insider threats, are based on an assumed compromise.

4. What Are Some of the Risks of Red Teaming?

Ensuring adequate coverage is one of the most frustrating parts of a red team operation. During an engagement, the red team’s goal is to identify any way to get into your system and access your sensitive data. They’ll thus look for a way to prevent them from being caught.
