What is red teaming?
Let's understand what it truly means to red team something.
Most of us in cybersecurity think of red teaming as a form of security testing. While this is true, conceptually red teaming is much more than security testing.
The concept of red teaming can be traced back to an old practice in the Vatican known as the "Devil’s Advocate." When the Catholic Church was considering someone for sainthood, they appointed a person whose job was to argue against the sainthood. This person, known as the Devil’s Advocate, would challenge the candidate’s qualifications, scrutinizing their life and actions to find weaknesses in the argument for sainthood. The purpose was not to be adversarial for its own sake, but to ensure a well-rounded and critical evaluation of the decision. This practice ensured that assumptions were challenged and that a more rigorous decision-making process took place.

The term "red team" itself, however, was coined during the Cold War between the United States and the Soviet Union. In this era, military strategists in the U.S. needed to understand how the Soviet Union, or "the enemy," might act in different situations. To accomplish this, they formed a group of specialists whose sole job was to think like the Soviet military. These teams, representing the "red" side (since the Soviet Union was commonly associated with the color red), analyzed how an adversary might attack the U.S. and identified weaknesses in the country's defenses. The U.S. military, which represented the "blue" side, could then use this analysis to strengthen their security and develop counter-strategies. The primary goal of red teaming was, and still is, to challenge assumptions, expose vulnerabilities, and help organizations prepare for real-world threats.
Although red teaming originated in military strategy, its applications extend far beyond the battlefield. Today, red teaming is widely used in intelligence operations, business strategy, homeland security, and cybersecurity. In each of these fields, the fundamental principle remains the same: challenging assumptions to improve preparedness. For example, businesses use red teams to test market strategies and identify risks before launching new products. Intelligence agencies use red teams to simulate how adversaries might operate in espionage or terrorist activities. Homeland security agencies conduct red teaming exercises to test the effectiveness of emergency response plans.
When cybersecurity professionals conduct red team assessments, they take on the mindset of an attacker and attempt to breach a company’s security defenses. Their goal is to identify weaknesses before real attackers can exploit them. This approach is different from traditional security testing because it focuses on simulating real-world adversaries. Ultimately, when red teaming information systems, organizations are challenging their assumptions about the security of these systems.
Red teaming is also a valuable tool in decision-making. Before making critical decisions, organizations can use red teams to test their strategies and identify potential flaws. By challenging ideas and assumptions, red teams help validate decisions before they are implemented, reducing the risk of failure. This approach is particularly useful in high-stakes environments such as business investments, military operations, and policy-making, where mistakes can have significant consequences. By anticipating challenges and refining plans beforehand, organizations can make more informed and effective decisions.
The core idea of red teaming is to challenge the status quo, uncover blind spots, and prepare for worst-case scenarios. By thinking like an adversary, organizations can anticipate potential threats and develop strategies to mitigate them. Whether in military strategy, business planning, intelligence operations, or cybersecurity, red teaming provides a structured way to think critically and test assumptions. It is a powerful tool for identifying what can go wrong and finding ways to fix it before a real crisis occurs. In any field where strategic planning and risk management are essential, red teaming remains a valuable practice for staying ahead of potential threats.
Red Team Notes
- Red teaming is a method of challenging assumptions and identifying weaknesses. It is used in various fields, including business, intelligence, cybersecurity, and decision-making, to test strategies, improve preparedness, and uncover risks before they become real problems. By simulating adversarial thinking, organizations can strengthen their defenses, refine their plans, and make better-informed decisions before taking action.Follow my journey of 100 Days of Red Team on WhatsApp, Telegram or Discord.
