> [!abstract] In short: A Red Team is a group of security professionals who simulate real-world attacks on an organization's systems, networks, and people. Unlike standard checks that only look at technical flaws, a Red Team tests everything: technology, people and physical security. ## What it is A Red Team plays the attacker, on purpose and with permission. They simulate genuine attacks to test an organization's defenses end to end. The difference from a routine security check is scope: instead of scanning for technical bugs alone, a Red Team comes at you from every angle a real adversary would, including the human and physical ones. ## The locksmith analogy Think of a Red Team as master locksmiths hired by a jewelry shop owner who wants to know if the store is truly safe. They don't just check the front door. They try every window, every back entrance, see whether an employee can be tricked into letting them in, and test whether the alarm reacts in time. They're not there to steal anything, just to find every weakness before a real thief does. ## Inside the team Red Teams mix specialists so they can attack from multiple directions at once: - **System hackers** find loopholes in software and networks. - **Social engineers** trick people into revealing information, for example impersonating a colleague to get a password. - **Physical security experts** try to enter secure buildings without authorization. One member might send phishing emails hoping someone clicks a malicious link, while another slips through an unlocked door or talks their way past a guard. Combining these uncovers vulnerabilities that live in the gaps between technology and human behavior. ## How an engagement works Red Team engagements are usually long-term projects, running for weeks or months. 1. **Recon:** Gather public information about the company (websites, employee profiles, anything useful) to find entry points. 2. **Planning:** Decide the approach and the attack scenarios. 3. **Execution:** Breach the defenses through hacking, exploiting bugs or deceiving employees. 4. **Documentation:** Track what worked, what didn't and why. 5. **Report:** A detailed write-up of how they got in, what data they reached and recommendations to close the gaps. Usually delivered to senior leadership like the CISO. > [!info] The team works quietly, so most employees don't know the test is happening. That way the reactions observed are genuine, not influenced by people knowing it's a drill. ## Objectives - **Assess human factors**: how susceptible employees are to phishing and social engineering, since those are common entry points. - **Test physical security**: access controls, surveillance, on-site protections. - **Challenge assumptions**: confirm that what's believed to be secure actually holds up. - **Simulate realistic, multi-vector attacks**: the kind advanced adversaries actually use. - **Improve incident response**: so the organization reacts faster and better in a real incident. - **Evaluate awareness and training**: spot where employee education needs work. - **Check supply chain security**: identify risks from third-party vendors or partners. - **Analyze digital footprint**: reduce risks tied to information leakage and social media exposure. > [!tip] Thhe point is never to embarrass anyone. It's to find the weak spots before a real attacker does, and then help leadership decide where to invest: training, technology, physical controls, or all three. A Red Team is the friendly version of the [[Threat Actors|threat actor]], using the same playbook to a better end.
