Penetration testing plays a vital role in FedRAMP assessments, and red team testing represents this domain’s most advanced and realistic evaluation form. This article delves into the scope, process, and value of red team penetration testing in the FedRAMP context, providing insights for cloud service providers, third-party assessment organizations, and federal stakeholders.

 

Understanding Penetration Testing in FedRAMP

Penetration testing in FedRAMP is a mandatory requirement expected to occur annually or after significant system changes. Its primary purpose is to identify security weaknesses that adversaries could exploit proactively. 

The test is governed by NIST SP 800-115 and the FedRAMP Penetration Test Guidance and must be conducted by a FedRAMP-accredited 3PAO. The assessment encompasses all in-scope system components and must be carried out within clearly defined authorization boundaries. 

Attack vectors evaluated typically include access from external and internal sources, privilege escalation, and attempts to exploit system misconfigurations.

FedRAMP mandates that the test results be incorporated into the Security Assessment Report, which becomes part of the system’s overall security package. This ensures that federal agencies leveraging the system know any residual risk.

 

What Is Red Team Testing?

Red team testing is an advanced penetration testing that goes beyond vulnerability identification. Unlike a traditional pen test that transparently probes and identifies vulnerabilities, a red team test simulates a real-world adversary using a combination of technical exploits and social engineering tactics. The goal is to test the organization’s ability to detect, respond to, and recover from a real attack.

Unlike conventional penetration tests focusing on technical vulnerabilities, red team exercises assess an organization’s security apparatus, including policies, user behavior, and response mechanisms. Red teams emulate tactics from known threat actors, using tools and techniques grounded in current threat intelligence, such as the MITRE ATT&CK framework. This type of testing provides a holistic view of security resilience and operational readiness.

 

When and Why to Conduct Red Team Exercises

Red team exercises are not explicitly mandated in all FedRAMP authorizations, but are highly encouraged for high-impact systems or environments with elevated risk profiles. 

The value of red team testing lies in its realism. It provides stakeholders with intelligence on how a determined attacker could exploit weaknesses in people, processes, and technologies. For CSPs, it presents an opportunity to test incident detection and response capabilities under controlled but highly realistic conditions. For federal agencies, it assures them that the cloud systems that house their sensitive data are resilient to real-world threats.

 

Planning a Red Team Engagement

A successful red team engagement begins with thorough planning. The CSP, 3PAO, and AO must collaborate to define the scope, rules of engagement, and test goals. This ROE document is a critical component and must be approved before testing begins, as it outlines the boundaries, allowable tactics, testing schedule, communication protocols, and safeguards to prevent unintentional service disruption.

Key steps in planning include:

  • Define Objectives: Clarify what the test aims to evaluate (detection capabilities, incident response).
  • Identify Scope: Select systems, environments, and interfaces that will be included in the test.
  • Develop the Rules of Engagement: Establish acceptable techniques, boundaries, and escalation protocols.
  • Assign Roles and Responsibilities: Designate contacts and stakeholders from CSP and 3PAO teams.
  • Establish Communication Protocols: Define how and when stakeholders will communicate during the test.
  • Schedule the Test: Choose a time window that minimizes operational disruption and allows adequate monitoring.
  • Review and Approve Plans: Secure formal AO approval on all planned activities before execution.

Testing must include the mandatory attack vectors identified by FedRAMP, such as External to Corporate, External to CSP Target System, and Tenant-to-Tenant scenarios. 

 

Executing the Red Team Test

Red teams may exploit vulnerabilities, evade detection systems, and attempt lateral movement across the environment. Social engineering tactics, like phishing, may also be used to test user awareness and training effectiveness.

Throughout the test, communication with the CSP’s security operations team is maintained at agreed-upon intervals or under predefined conditions (if a test escalates beyond control). Testing is aligned with NIST SP 800-115 methodologies and includes:

  • Reconnaissance: Gathering information about the system, infrastructure, personnel, and potential entry points.
  • Exploitation: Attempting to gain unauthorized access using known vulnerabilities or newly discovered weaknesses.
  • Post-Exploitation: Expanding access, elevating privileges, moving laterally within the network, and identifying sensitive assets.
  • Cleanup: Restore the system to its original state, remove any test artifacts, and ensure no lingering impacts remain.

A key feature of red team exercises is measuring time-to-detect and time-to-contain. These metrics help determine how quickly and effectively a CSP can identify and mitigate unauthorized activity.

 

Reporting and Remediation

Upon completing the red team test, the 3PAO produces a comprehensive report detailing the findings, methodologies, attack paths, and potential impact. This report must be submitted as part of the broader Security Assessment Report. The findings should be categorized by risk severity, and remediation recommendations must be provided.

The CSP addresses the findings through a Plan of Action and Milestones (POA&M). This document tracks the remediation status and timelines for resolving identified issues. Transparency and prompt remediation are critical for maintaining FedRAMP authorization and demonstrating a commitment to continuous improvement.

Red team results also serve as valuable input for refining incident response plans, training programs, and security configurations. To maximize the exercise’s value, organizations are encouraged to conduct internal debriefs and lessons-learned sessions following a red team engagement.

 

Trust Lazarus Alliance with Red Team Testing

Red team penetration testing is a vital tool in the FedRAMP security toolkit. These exercises offer unparalleled insight into a CSP’s real-world security posture by emulating sophisticated adversaries. Although not always required, red team testing is a best practice, especially for systems managing sensitive federal data or operating at the high-impact level.

Navigating the complexities of CMMC compliance demands a strategic approach to documentation and policy development. Organizations can build a robust cybersecurity framework that meets compliance requirements and enhances overall security resilience by recognizing and addressing common pitfalls such as inadequate documentation, misalignment between policies and procedures, and insufficient training.
