Red Teaming

Red teaming is the technique of using an adversarial approach to thoroughly challenge plans, policies, systems, and assumptions. A red team can be a contractual external party or an internal

an organization that employs techniques to encourage an outsider's viewpoint.

The purpose of red teaming is to overcome cognitive errors like groupthink and confirmation bias, which can hamper an individual's or organization's decision-making or critical thinking abilities.

The Red Team is made up of offensive security experts who target cybersecurity defenses. Red teams are "ethical hackers" who aid in the testing of an organization.

when it comes to Red Team Security

  • Red Teaming is a type of penetration testing in which the goal is to avoid detection by Blue Teams and to remain in the target environment for as long as possible. It is a type of offensive security testing that focuses on investigating post-compromise assaults.

  • Red teaming is similar to vaccine administration in that it prepares the host (in this case, the organization) to learn how to fight back if an actual foreign body [black hat adversaries, rogue nation-state actors, and advanced persistent threats (APTs), etc] enters the system (network).

  • Blue teams are also known as defenders. They are typically made up of SOC teams, and IT infrastructure teams such as Server Teams, Network Teams, and Incident Response Teams, among others. The SOC Team monitors events and threats and, depending on their intelligence, the Infra Team further safeguards the infrastructure, i.e. Blue Teams are reactive, which means they wait for things to happen.

  • Red Teams are continually simulating attacks on the IT infrastructure. They are proactive by nature. They act like genuine attackers when penetrating defenses and attempting to enter and remain undiscovered within the network. Their goal is to highlight gaps in defenses to improve the overall security posture.

  • Red Teams can catalyze for blue teams to base the setting of their security solutions on their attack paths and post-compromise behavior.

  • Whereas penetration testing includes evaluating defenses, Red Teaming focuses on testing defenses and measuring Blue Teams' overall capabilities to see how soon they can notice and respond to an actual anomaly.

  • To assess an organization's readiness to identify and respond to assaults.

  • To determine how quickly the organization detects a breach and the presence of unauthorized foreign individuals on their network.

  • To evaluate the Incident Response Team's efficiency.

  • Determine the organization's use of the cyber-security maturity model.

  • To comprehend the immediate actions that an organization would take following an attack.

  • If a business has a comprehensive IT infrastructure with a dedicated blue team that includes SIEM/SOAR (Security Information and Event Management / Security Orchestration, Automation, and Response), EDR (Endpoint Detection and Response), AV (Antivirus), FIM (File Integrity Monitoring), and PAM (Privilege Access Management), they should conduct a Red Team exercise.

  • Red teaming can be done in a variety of ways. Before we get started, let's define simulate and imitate. According to the Cambridge Dictionary, imitate means copying something accomplished by someone else and trying to do it as well as they have. Simulate implies doing or manufacturing anything that appears real but is not real.

  • Let us now look at the various approaches:

  • Adversary Simulation: Red teamers will utilize various TTPs (Tactics, Techniques, and Procedures) to simulate attacks. The MITRE ATT&CK framework can serve as a reference guide for the same.

  • Adversary Emulation: Red teamers will attempt to emulate the behavior of a real-life criminal hacking operation, group, or institution. All TTPs utilized will be designed to simulate how a specific APT group will operate if and when they infiltrate the network. The outcome of such a security evaluation will determine how prepared the organization is to meet a certain enemy. This is primarily concerned with replicating specific bad actors rather than taking a broad approach.

  • Purple Teaming: Instead of working individually according to respective calendars, the Red Team and Blue Team collaborate under the same leadership umbrella of Purple Teaming. Here, Red Teaming will supplement Blue Teaming, i.e. Before moving further, both teams will work in close cooperation to achieve the common aim of securing the company against that specific attack scenario.

  • The report here is similar to penetration testing, but it also includes a separate detection section for blue teamers to refer to so that they may configure all IT security devices to detect the attack as soon as possible.
