Red Teaming

Full-scope adversary simulation measuring how your people, networks, and defenses withstand a real-world attacker.

A controlled adversary path moving through an enterprise network toward a protected objective

Controlled security analysis

Introduction

Definition

A Red Team's objective is to conduct a realistic, comprehensive security audit of an organization, focusing on the essential components of people, processes, and technology. This is achieved by simulating sophisticated cyberattacks that replicate the Tactics, Techniques, and Procedures (TTPs) utilized by real-world adversaries.

Red team assessment scope across people, process, and technology

Technologies

Security tools tested via realistic attack simulations — exposed assets, intrusion detection, malware protection

Personnel

Employee preparedness assessed via social engineering scenarios, security awareness, team reaction to alerts

Processes

Incident management protocols tested — detection, response, coordination during incidents

Comparison

Red Team vs. Penetration Test

Penetration Testing and Red Teaming are distinct approaches in security testing, differentiated by their goals and methods.

Red Teaming

Wider immersive strategy simulating realistic sophisticated attacks against entire defensive posture. Tests overall capability to detect, prevent, respond.

Penetration Testing

Identifies specific system vulnerabilities within defined scope, evaluates impact, recommends corrections. Best for new applications before deployment.

Crucially, Red Teaming and Pentesting are not opposing methodologies; they are complementary. While Pentesting assesses the security of specific components, Red Teaming evaluates the overall effectiveness and resilience of the security program.

Coordinated red, blue, control, and threat-intelligence teams

The Teams

Control Team

Primary liaison between client and provider. Supplies info to Threat Intelligence, coordinates with Red Team without disclosing to Blue Team.

Blue Team

Client's internal security teams detecting and responding to simulated attacks. May be kept uninformed about scenarios.

Threat Intelligence Team

Handles test preparation — gathers and analyzes threat info, develops customized attack scenarios.

Red Team

Executes simulated attacks following TI-defined scenarios, testing overall security posture.

Red Team Stages

The standard stages of a Red Team engagement typically align with established frameworks such as the Cyber Kill Chain or MITRE ATT&CK.

Seven connected stages of a red team engagement

3.1. Planning and Objectives (The "RoE")

Before any technical work begins, the rules must be set to ensure safety and value.

Goal Definition: Defining the "Crown Jewels." What is the Red Team trying to capture? (e.g., access the CEO's email, exfiltrate customer PII, or gain domain admin rights).
Rules of Engagement (RoE): A legal document defining the scope, allowed testing hours, prohibited targets (e.g., life support systems), and emergency contact numbers.
Threat Intelligence: Deciding which type of adversary to emulate (e.g., a specific nation-state actor or a ransomware gang) to ensure the TTPs (Tactics, Techniques, and Procedures) are realistic.

3.2. Reconnaissance (The "Stakeout")

The team gathers as much information as possible about the target without raising alarms.

Passive Recon (OSINT): gathering data from public sources.
Active Recon: Carefully probing the network perimeter.

3.3. Initial Access (The "Breach")

The team attempts to gain a foothold in the environment. This is rarely a "smash and grab"; it is usually subtle.

Social Engineering: Spear-phishing emails, vishing (voice phishing), or physically tailgating into a building.
Exploitation: targeting unpatched vulnerabilities in public-facing applications (VPNs, Web Servers).
Payload Delivery: executing malware on a victim's machine to establish a connection back to the Red Team's server.

3.4. Command and Control (C2) & Persistence

Once inside, the goal is to stay inside.

C2 Channels: Establishing a covert communication channel between the compromised internal machine and the Red Team's external server. This traffic often mimics legitimate traffic (like HTTPS or DNS) to blend in.
Persistence: modifying the system (e.g., scheduled tasks, registry keys) so that if the user reboots their computer, the Red Team does not lose access.

3.5. Lateral Movement and Escalation

The initial entry point is rarely the final destination. The team must move through the network.

Privilege Escalation: Going from a standard user account to an Administrator or Root account using local exploits.
Internal Recon: Mapping the internal network, finding file shares, and identifying where the "Crown Jewels" are located.
Pivoting: Using the compromised machine as a jump-box to access other restricted subnets that aren't accessible from the internet.

3.6. Action on Objectives

Data Exfiltration: Stealing the targeted data (often slowly or encrypted to avoid DLP triggers).
Impact Demonstration: Creating a "proof of life" file on a sensitive server to prove access was achieved, without actually harming the system.

3.7. Reporting and Remediation

Executive Summary: A high-level overview of the risks and business impact for leadership.
Technical Report: A timeline of the attack, screenshots of access, and specific details on how controls were bypassed.
The "Purple Team" Debrief: A collaborative workshop where the Red Team shows the Blue Team (defenders) exactly what they did, timestamp by timestamp, so the Blue Team can check their logs and tune their alerts.
