What is a Red Team?
Red Team— A team of highly qualified security professionals who perform an attack in a real environment on the systems, networks, and infrastructure of the organization. Their main goal is to discover vulnerabilities, weaknesses, and access points that bad actors can exploit. Red teams use an adversarial mindset to drive the organization towards improving its security posture to reduce the potential for and impact of successful attacks on the organization.
Red Teams commonly use a variety of tactics, techniques, and procedures (TTPs) from real-world threat actors, such as
- Social engineering
- Phishing campaigns
- Exploit development
- Physical security breaches
- Wireless network attacks
By emulating real-world attacks, these simulated threats can highlight security holes in an organization, enabling it to patch up publicly exploitable weaknesses before an actual attacker attempts to take advantage of them.
Red Team Members
Red Team members are highly skilled and specialized professionals. An example Red Team might consist of:
- Penetration testers
- Ethical hackers
- Social engineers
- Malware analysts
- Exploit developers
All members have unique skills and abilities that they can apply to the team to solve security challenges from various perspectives. Red Team personnel should be able to replicate real threats as needed, so they require a mix of technical expertise, creative problem-solving, and a strong familiarity with attacker techniques.
Having introduced Red Teams, their purpose, and their members, now we must consider the other side of the coin: Blue Teams.
What is a Blue Team?
Going by the cybersecurity terminologies, the Blue Team acts as a defensive team against the Red Team. They work to safeguard an organization’s digital assets from insider and outsider threats. The Blue Team is a reactive (continuous) security resource watching over networks, systems, and applications to identify, analyze, and combat potential breaches.
The key goals of a Blue Team are as follows:
- It deals with Threat detection and prevention
- Incident response and management
