Pentest vs. Red Team Assessment

In IT security, the terms Red Team Assessment and pentest are often confused. This blog post compares and contrasts both concepts. It also examines which approach delivers the greatest value at what stage of maturity, and what business challenges are associated with each assessment.

Red Teaming

Red Teaming is used to test an organization's detection and response capabilities. The Red Team attempts to access sensitive information by any means possible while remaining undetected. This type of assessment emulates a malicious actor who is actively attacking and evading detection, similar to an Advanced Persistent Threat (APT). A Red Team Assessment does not aim to find as many vulnerabilities as possible, but rather focuses on the specific weaknesses that can be exploited to achieve defined objectives. A pentest, on the other hand, is designed to uncover as many vulnerabilities and configuration issues as possible, exploit them, and determine the associated risk level. Methods used in a Red Team Assessment include social engineering (physical and electronic) as well as all techniques commonly employed in a pentest. A pentest typically lasts 1-2 weeks, while a Red Team Assessment can span 3-4 weeks or longer and often involves multiple specialists.

However, a Red Team Assessment is not suitable for every organization. It is best suited for organizations with mature security programs that conduct pentests regularly, have remediated most known vulnerabilities, and generally demonstrate positive pentest results. Key benefits include:

• Measurable detection and response capability of IT security
• Realistic risk understanding for the organization
• Assistance in remediating identified attack vectors

Red Teaming operations pursue clearly defined objectives using a coordinated, multi-stage approach. They typically require more personnel, resources, and time, as they go deeper to fully assess the realistic extent of risks and vulnerabilities across an organization's technology, people, and physical assets. The NIST defines Red Teaming.

Penetration Testing

Penetration testing aims to identify vulnerabilities at the application, network, and system level, as well as potential ways to compromise physical security barriers. While automated scans can detect some security issues, real pentests also involve manual analysis of the organization's specific attack vectors.

The differences between a pentest and a Red Team Assessment are often misunderstood, which is why both types of assessments are frequently and incorrectly referred to simply as pentests. Although they share certain components, each serves a distinct purpose and should be applied in different contexts. At its core, a genuine pentest seeks to find and exploit as many vulnerabilities and configuration issues as possible within the allotted timeframe, in order to determine the actual risk each vulnerability poses.

This does not necessarily mean uncovering previously unknown vulnerabilities such as zero days. Instead, the focus is on identifying known, unpatched weaknesses. A pentest is designed to find and validate vulnerabilities, ensuring that findings are not false positives. However, pentesting goes further: the pentester attempts to chain multiple vulnerabilities together to achieve a defined objective. Since every organization is different, this objective may vary, but it typically involves gaining access to personally identifiable information or trade secrets.

When a network, application, cloud/server infrastructure, and physical security are examined through the eyes of a pentester, the following can be determined:

• Which attack vectors can be exploited
• How the systems may be attacked
• What hardening measures are needed
• What potential damage could result

In today's complex cybersecurity landscape, pentests have become essential for most industries. Even organizations that believe they have no valuable information to protect face the risk of attackers attempting to take over their network, install malware, or disrupt services. Given the sheer number of malicious actors, pentesting must continually keep pace with evolving technology.

Which Service Do You Need?

Is a pentest better than Red Teaming? In many cases, pentesters and Red Team members are the same professionals, applying different methods and techniques depending on the objective. The answer to the question of pentest vs. Red Teaming is: one is not better than the other! Each approach serves its purpose in specific situations. It does not make sense to commission a pentest to evaluate an organization's detection and response capabilities. Equally, Red Teaming is not the right choice for systematically identifying vulnerabilities across the entire application layer.
