What is a Red Team?
A red team is a group of ethical hackers who act as potential attackers. By adopting the hackers’ perspective, they simulate potential cyber- attacks. As such, they aim to exploit any security weaknesses—both physical and digital—present within your company’s operations.
To a larger extent, the red teamers uses this practice to find these unique vulnerabilities. These would potentially remain hidden from the standard audit. Through this process of ethical hacking, red teams help you understand your security posture. They expose weaknesses that could be opportunistically targeted by malicious hackers, and effectively manage your risk.
Red teaming, which includes comprehensive penetration tests, has become a pivotal technique in cybersecurity to emulate real-world cyber attacks and, in turn, gauge a company’s security defences.
Aside from providing businesses with this valuable perspective, red teaming is also an essential part of a comprehensive security strategy.
How Does a Red Team Work?
Red teaming involves a specialised cybersecurity team—the red team—to independently simulate an attack on an organisation’s defensive cybersecurity capabilities.
They try to gain access to predetermined objectives by discovering vulnerabilities anywhere within the organisation. Then, they devise strategies to exploit them.
These vulnerabilities may be known ones that have been previously identified in code analysis or penetration testing. They can also be unique weaknesses bespoke to the organisation’s infrastructure.
These offensive security experts leverage a variety of attack techniques, including social engineering, physical intrusion, application, and network exploitation.
Red Team Exercises
Here’s a glimpse of what a typical red team exercise might look like.
Reconnaissance
Red teams usually start by collecting information about your business, usually through public sources. They may establish an initial understanding of the organisation’s structure, internal network, and security controls. They’d probably do this by investigating job titles, software development procedures, and network configurations.
Initial Access
Using the information gained earlier, the red team devises unique ways to penetrate your company’s defences. A typical technique involves a carefully crafted phishing email aimed at tricking an employee into unknowingly surrendering their user credentials.
Privilege Escalation & Persistence
Once they’ve gained an initial entry, red teams then look to escalate their privileges within the system. Often, they’d use them to move laterally through the network to gain additional access and strengthen their foothold.
Objectives, Command, and Control
Red teams attempt to accomplish predetermined objectives. These may include the exfiltration of data or taking command of particular systems.
Conclusion & Recommendations
Post-attack, red teams document their techniques, targets, and outcomes to provide a detailed report. This usually includes recommendations for how you can fortify your defences and response methods moving forward.
Red teaming is often contrasted with blue teaming. That is another integral component of organisational security. The blue team—composed of incident responders—defends against and responds to the red team’s attacks.
These real-world attack techniques provide tremendous value to organisations. They help highlight their security vulnerabilities. And, shine a light on where defensive capabilities need to be increased to prevent breaches.
What is a Blue Team?
In cybersecurity, a blue team consists of the organisation’s internal security staff. Its role is to defend against both real and simulated cyber threats.
The blue team implements robust defence mechanisms, conducts regular system audits, and ensures compliance with security policies. That way, it protects the organisation’s data and infrastructure.
Blue teams are the defenders in the cyber realm. They actively monitor, detect, and respond to attacks identified by their red team counterparts or actual adversaries.
Through continuous vigilance and employing cutting-edge security technologies, blue teams fortify the business’s defences. They minimise vulnerabilities, and maintain the integrity of its cyber environment.
Red Team vs. Blue Team
In a red team/blue team exercise, the red team takes on the role of offensive security experts. They launch realistic and targeted attacks on a business’s cybersecurity defences.
They employ real-world attack techniques and use creativity to identify and exploit weaknesses.
In contrast, the blue team is composed of incident responders and the IT security team. It defends against the red team’s campaigns and responds to breaches.
This is an adversarial emulation exercise. Red team members might use common tactics such as social engineering attacks or the exploitation of known vulnerabilities. Using these, they gain access to the internal network.
They might also simulate threats that target specific parts of a business’s infrastructure. For this, they may use a wide range of methods like endpoint security bypass or privilege escalation.
On the other hand, the blue team is responsible for detecting, responding and preventing these simulated attacks. This team plays a crucial role in enhancing a company’s defensive cyber security capability. It helps improve incident response and, ultimately, helps organisations become more resilient against real-world cyber attacks.
What is a Purple Team?
So, the red and blue teams represent the offensive and defensive aspects of cybersecurity respectively. However, the concept of a purple team transcends this adversarial approach.
Purple teaming is a more collaborative effort to enhance an organisation’s security posture. Whilst red or blue teams work independently, a purple team isn’t a separate entity but rather a function. It bridges the gap between the two, facilitating a continuous feedback loop.
The red team comes up with offensive tactics. The blue team creates defensive strategies. The primary goal of a purple team is to ensure that both are fully integrated into your organisation’s cybersecurity practices.
This integration aims to maximise the effectiveness of security measures by leveraging insights from both perspectives.
How Does a Purple Team Work?
A purple team operates by analysing the red team’s attack methodologies and the blue team’s responses to them. They focus on understanding why certain attacks were successful and how defence mechanisms can be improved.
Through workshops, training sessions, and debriefings, purple teams foster a culture of knowledge sharing and continuous improvement.
Key responsibilities of a purple team include:
Enhancing Detection and Response
By reviewing the red team’s attack paths, purple teams help the blue team improve their detection capabilities and response strategies.
Optimising Tools and Processes
They evaluate the effectiveness of current security tools and processes. Then, they use their findings to recommend adjustments or new solutions that can better protect against future attacks.
Knowledge Transfer
Purple teams facilitate the exchange of expertise between red and blue teams. They ensure that both teams learn from each other’s experiences and techniques.
The Role of Red Teams in Cybersecurity
Red teams play an indispensable role in assessing your organisation’s defences against real-world threats through comprehensive a red team assessment. Their unique approach simulates attacker tactics and techniques such as those listed in the MITRE ATT&CK framework, transecting over the entire cyber attack lifecycle from initial access to exfiltration.
Their probing assessments test the effectiveness of security measures from an adversarial perspective. They check how effective these measures are in areas such as reconnaissance, gaining and maintaining access, and data exfiltration.
Red teams actively participate in exercises that involve simulating cyber threats. They independently and creatively circumvent cybersecurity controls. This way, they reveal how resilient the established defences can be against a persistent and motivated attacker.
The knowledge gained through these red team engagements is invaluable. It aids businesses in uncovering vulnerabilities often obscured by day-to-day challenges.
As such, their findings and recommendations, based on up-to-date threat intelligence and understanding of various risks, help businesses bolster their security strategies, beef up their defence capabilities against cyber attacks, and fine-tune their security systems.
Benefits and Considerations of Red Teaming
It would be remiss not to recognise the inherent benefits of red teaming. It provides your business with critical insights into your security posture, delivered by the skilled perspective of a Red Team Member. And, it helps identify weaknesses that would have otherwise gone unnoticed.
You can use these simulations of real-world attacks to proactively address vulnerabilities. You can improve defences and comprehend your unique security posture in the current cybersecurity landscape.
However, it’s equally important to consider the cost and resources required for conducting such rigorous and extensive red-team testing.
There is a potential cost that comes with a data breach. However, a red team engagement is also an expense. It falls on your business to balance the two and determine where to allot your security budget.
Also, these simulations should be performed by experienced offensive security teams, including a qualified red team member, to bring about accurate and effective results.
By examining their advisory services and certifications, you can ensure you are employing comprehensive red team services. That way, you can meet your specific needs and industry guidelines.
Finally, staff training should be prioritised as a preventative measure. That’s because most common cyber attacks usually target unsuspecting staff via phishing emails and other social engineering techniques.
Red Teaming vs Penetration Testing
Understanding the distinction between red teaming and penetration testing (pentesting) is crucial for companies aiming to strengthen their cybersecurity posture. Both are critical for identifying security vulnerabilities. However, their approaches, objectives, and outcomes significantly differ, catering to different aspects of security readiness.
Objectives and Scope
Penetration testing (Pen Testing) is a focused effort aimed at identifying and exploiting vulnerabilities in specific parts of your organisation’s IT infrastructure. Pentests are usually scoped around certain systems, applications, or networks. The goal is to uncover as many vulnerabilities as possible within the predefined scope. This process helps you fix security gaps before they can be exploited by attackers.
Red teaming, conversely, adopts a broader, more strategic approach. The main goal of red teaming is to test how well your organisation can detect and respond to secret, ongoing attacks that imitate real-world enemies. Red teams engage in a full-spectrum assault that tests physical, digital, and human defences. They provide a comprehensive evaluation of your business’s security resilience.
Methodology and Tactics
Penetration testing methodologies are well-defined. Testers will typically follow industry standards such as OWASP for web applications. Pentests often employ automated tools to scan for vulnerabilities, supplemented by manual techniques to exploit them. The process is highly technical, focusing on specific vulnerabilities and how they can be patched.
Red teaming methodologies, however, are less structured. They use creativity and adaptability. Red teams use a blend of technical and non-technical tactics, including social engineering, physical security breaches, and advanced persistent threats (APTs). This approach is designed to test your end-to-end security capabilities. It tests the effectiveness of incident detection, response procedures, and employee security awareness.
Duration and Frequency
Penetration testing is typically conducted on an annual or bi-annual basis. It offers snapshots of your organisation’s security at a point in time. These engagements are relatively short. They last from a few days to a couple of weeks, depending on the scope.
In contrast, red teaming exercises are more prolonged, often spanning several weeks to months. This duration allows red teams to conduct deep-dive assessments, simulating sustained attack campaigns.
Additionally, red teaming requires less frequent involvement due to its immersive nature. That ensures that you have time to digest findings and implement changes before the next engagement.
Outcomes and Reporting
The outcome of pen testing is a detailed report listing vulnerabilities, their severity, and recommendations for remediation. This report is actionable and technical, aimed at guiding IT teams in strengthening the security of specific systems.
The outcomes of red teaming also ultimately result in a comprehensive report. However, the focus is on providing strategic insights into your organisation’s overall security posture. These reports highlight gaps in detection and response capabilities. They offer recommendations that span policy, procedure, and people, in addition to technology.
So, how do you select between red teaming and penetration testing? Or, determine the right mix?
That depends on your business’s maturity level, regulatory requirements, and specific security goals. Most businesses need a combination of both. A mix of the two, strategically aligned with their risk management framework, offers the best path to robust cybersecurity.
Continuous Automated Red Teaming
Continuous automated red teaming is an advanced approach in cybersecurity. It signifies the progression of security practices.
The approach blends the thoroughness of red team exercises with the efficiency of automation. It utilises automated tools to simulate attacks continuously, allowing for real-time monitoring and improvement of security defences, under the umbrella of red team security strategies..
Continuous automated red teaming bridges the gap between periodic security assessments and the dynamic nature of cyber threats. It ensures that your business can rapidly detect and respond to vulnerabilities before they are exploited.
