Introduction
The main difference is Red Teaming simulates real-life attacks. While doing so, the objective is to remain as evasive and hidden as possible. The goal is not so much to beat the Blue Team, which during the whole exercise is expected to find, confine, and stop the attack, but to identify areas where the defense needs to be improved and the ability to respond to incidences be made efficient.
The term "red team" has its origins in the military. It was originally used to describe a group of military personnel tasked with simulating the enemy's tactics, techniques, and procedures (TTPs) to train and test friendly forces. The red team would adopt the role of the adversary and use a variety of techniques to try to defeat friendly forces or circumvent their defenses.
Over time, the term "red team" has been adopted by other fields, including information security, to describe a similar role. In information security, a red team is a group of skilled professionals who simulate real-world attacks against an organization's systems, networks, and people. The goal of a red team in this context is to identify vulnerabilities and weaknesses in an organization's security defenses that could be exploited by a real attacker.
The term "penetration testing" also has its roots in the military. It was originally used to describe a type of testing where a military unit would attempt to penetrate enemy lines to gather intelligence or carry out an attack. In the context of information security, penetration testing refers to a type of security assessment where a team of experts attempts to identify vulnerabilities in an organization's systems, networks, and applications by simulating an attack.
Types of Red Team Engagements
There are several different types of red team engagements, each with its own focus and objectives. Here are some common types of red team engagements:
External network red team engagement: This type of engagement focuses on testing an organization's external-facing network defenses. The red team attempts to gain unauthorized access to the organization's systems and data from the internet or other external networks.
Internal network red team engagement: This type of engagement focuses on testing an organization's internal network defenses. The red team attempts to move laterally within the organization's network to access sensitive data or systems.
Physical red team engagement: This type of engagement focuses on testing an organization's physical security defenses, such as access controls, security cameras, and security personnel. The red team attempts to access the organization's facilities or assets by exploiting physical vulnerabilities.
Social engineering red team engagement: This type of engagement focuses on testing an organization's employees' susceptibility to social engineering attacks, such as phishing, pretexting, or baiting. The red team attempts to trick employees into divulging sensitive information or granting access to systems or data.
Application red team engagement: This type of engagement focuses on testing an organization's application security. The red team attempts to identify vulnerabilities in the organization's applications that could be exploited by an attacker.
Hybrid red team engagement: This type of engagement combines multiple types of red team activities to simulate a realistic attack scenario. For example, a hybrid engagement might include elements of external and internal network testing, physical testing, and social engineering.
The specific type of red team engagement selected will depend on the organization's specific security goals and concerns.
TTPs (Tactics, Techniques, and Procedures)
In the context of information security, TTPs are the specific methods and tools that attackers use to exploit vulnerabilities in an organization's systems, networks, and data.
Tactics refer to the overall approach or strategy that an attacker uses to achieve their objectives. This might include selecting specific targets, using social engineering tactics to gain access to systems or data, or leveraging vulnerabilities in software or hardware.
Techniques refer to the specific methods or tools an attacker uses to achieve their objectives. This might include using malware to gain access to systems or data, exploiting a software vulnerability to gain unauthorized access, or using password-cracking tools to gain access to a user's account.
Procedures refer to the specific steps that an attacker takes to execute their tactics and techniques. This might include steps such as reconnaissance to identify potential targets, exploitation of vulnerabilities to gain access to systems, and exfiltration of data once access has been gained.
Understanding an attacker's TTPs can be valuable for organizations looking to improve their security defenses. By understanding the specific tactics, techniques, and procedures that attackers are using, organizations can better tailor their defenses to protect against these specific threats. This might include implementing specific security controls or training employees to be more aware of social engineering tactics.
What is a Kill-Chain
A kill chain is a model that describes the stages of a typical cyber attack, from the initial reconnaissance to the exfiltration of stolen data. Information security professionals often use the kill chain model to understand and defend against cyber attacks.
The kill chain model typically consists of several stages, varying depending on the specific framework used. A common example of the stages in a kill chain model are:
Reconnaissance: An attacker uses open-source intelligence (OSINT) tools and techniques to gather information about a target organization. This might include scanning the organization's website and social media accounts, searching for employee email addresses, or looking up information about the organization's suppliers and partners.
Weaponization: The attacker creates a weaponized payload, such as a malicious email attachment or a software exploit, that is designed to exploit a vulnerability in the target organization's systems.
Delivery: The attacker delivers the weaponized payload to the target organization, typically through email or a compromised website. For example, the attacker might send a phishing email to an employee with a malicious attachment that, when opened, installs malware on the employee's computer.
Exploitation: The attacker uses the weaponized payload to exploit a vulnerability in the target organization's systems. For example, the attacker might use a software exploit to gain remote access to a vulnerable server.
Installation: The attacker installs a backdoor or other malicious software on the target organization's systems. For example, the attacker might use the access they gained in the previous stage to install a remote access trojan (RAT) that allows them to control the compromised system remotely.
Command and Control: The attacker establishes a connection with the compromised systems or networks, enabling them to control and manipulate them as needed. For example, the attacker might use a command and control (C2) server to communicate with a network of compromised systems.
Actions on Objective: The attacker achieves their ultimate goal, which might include stealing sensitive data, disrupting operations, or causing other harm to the target organization. For example, the attacker might exfiltrate sensitive data from the target organization's systems and sell it on the dark web.
By understanding the stages of a typical cyber attack, information security professionals can identify specific security controls that can be used to disrupt the attack at each stage. This can help organizations better defend against cyber attacks and protect their critical assets and data.
How do the Red, Blue, and White teams work together?
The red team simulates attacks against the organization's systems, applications, and networks. The red team typically consists of experienced cybersecurity professionals with expertise in offensive security and penetration testing. The red team's objective is to identify weaknesses in the organization's security defenses and help improve them by demonstrating how an attacker could exploit vulnerabilities to gain unauthorized access.
The blue team is responsible for defending the organization's systems, applications, and networks against the simulated attack. The blue team typically consists of the organization's internal security team or a team of external security professionals who have been hired to provide defensive security services. The blue team's objective is to detect and respond to the red team's attack in real-time, using security tools and techniques to prevent the red team from achieving their objectives.
The white team is responsible for overseeing the exercise and ensuring that it is conducted safely and according to the rules and objectives of the exercise. The white team typically consists of neutral parties, such as independent consultants or internal auditors, who have no vested interest in the outcome of the exercise. The white team's objective is to evaluate the performance of the red and blue teams and provide feedback on how they can improve their security defenses.
During a red team exercise, the red team will attempt to use various techniques to compromise the organization's systems, such as phishing attacks, social engineering, and exploiting vulnerabilities in software and hardware. The blue team will use security tools and techniques, such as intrusion detection systems (IDS), security information and event management (SIEM) systems, and firewalls, to detect and respond to the red team's attack. The white team will monitor the exercise and provide feedback on the effectiveness of the red team and the blue team's tactics and strategies.
