Red teaming is a strategic cybersecurity practice where a trusted group of individuals, known as the red team, simulates an attack on an organization to test its defenses and identify vulnerabilities. This process is critical for entities reliant on software, such as banks, healthcare providers, and government institutions, which are at risk of cyberattacks like ransomware or data exfiltration. The red team operates without insider knowledge and aims to emulate real attackers by using stealth tactics, including social engineering and physical breaches, to challenge network, software, physical security, and personnel vulnerabilities. Unlike penetration testing, which is more controlled and known to the security team, red teaming involves an unannounced and adaptive approach to create a realistic threat environment. The exercise concludes with the red team reporting their findings, which the organization uses to fortify its defenses. Continuous red teaming is recommended for ongoing security assessment, offering real-world metrics to measure security team performance and justify further security investments.
