What Is A Red Team Exercise & Why Is It Important?

In the age of digital warfare, cybersecurity threats and attacks are increasing exponentially, inflicting a loss of millions of dollars. Modern adversaries can endanger the reputation of organizations of all types and sizes. These threat actors devise new plans and strategies to penetrate networks, perform data exfiltration, and bring the entire business to a standstill. To combat these threats, organizations mostly rely on the practice known as red teaming services. 

‍

Red teaming is a systematic and structured approach to test the enterprise’s cyber defense capabilities. Red teaming incorporates highly skilled experts who simulate the Tactics, Techniques, and Procedures (TTPs) of real-world hackers. Utilizing the same methods and tools as cybercriminals, these experts identify weaknesses and vulnerabilities that may go undetected or unnoticed. Unlike hackers, their goal is to enhance the network security of the targeted organization. 

‍

This article will explore red teaming exercises, the role of red teaming, blue teaming, and purple teaming, and why red teaming services are essential for organizations. 

‍

[fs-toc-h2]What Is A Red Teaming Exercise?

‍

Red teaming exercise is a security practice that involves red teaming methodologies and threat emulation tools to find and mitigate cybersecurity risks on corporate systems, applications, and networks. Highly skilled cybersecurity professionals, also known as ethical hackers from red teaming simulate a nondestructive real-world cyber-attack to discover potential weaknesses and vulnerabilities. 

‍

The red teaming services aim at identifying gaps and vulnerabilities and providing recommendations to strengthen the organization’s security posture. 

‍

The red team engagements are proactive as they identify vulnerabilities on time, preventing the sophisticated adversaries and Advanced Persistent Threats (APTs) groups from exploiting such vulnerabilities and carrying out attacks and data breaches. The red teaming covers physical, digital, and compliance domains. It also fixes the potential vulnerabilities caused by human factors. 

‍

The objective of a red team exercise is to test the security level of a business, list all identified vulnerabilities, and demonstrate how well a business is prepared and respond to a real cyber-attack. The test reveals the effectiveness of an organization’s risk management system, including people, processes, and technologies. 

‍

The red team engagements mostly target the following security controls: 

‍

• Web servers and web applications
• SOAR platform 
• XDR and EDR 
• Firewall
• IDS and IPS 
• Smartphones and workstations 

‍

[fs-toc-h2]A Real-World Example

‍

In 2022, the Cybersecurity and Infrastructure Security Agency (CISA) published a report regarding its red teaming assessment. The CISA red team conducted this assessment against a multinational organization with a large critical infrastructure to uncover weaknesses and vulnerabilities.

The report emphasizes the primary vulnerabilities found through this exercise, including:

‍

• Inadequate endpoint monitoring 
• Excessive permissions to users 
• The use of insecure default configurations
• Insufficient network and host monitoring 
• Potentially unwanted programs 

• Lack of network visibility
• Ineffective threat detection
• Lack of security awareness training

‍

In this report, CISA provided recommendations to the organization on measures to enhance its security posture: 

‍

• Improve system hardening
• Initiate an ongoing security awareness and training program
• Enhance threat detection capabilities
• Strengthen network monitoring 
• Perform regular security audits

‍

In a nutshell, the report emphasizes the significance of proactive and robust network security with effective security controls, vigilant monitoring, and a robust Incident Response Plan (IRP).

[fs-toc-h2]What Do You Need to Know About Red Teaming Vs Blue Teaming Vs Purple Teaming? 

‍

Red teams, blue teams, and purple teams consist of cybersecurity professionals who have diverse roles in enhancing the organization’s cybersecurity. The following sections delve into each team in detail. 

‍

Red Teaming

‍

The red team acts like an attacker and uses the same tools and techniques to infiltrate the corporate IT infrastructure. The objective is to uncover potential vulnerabilities and weaknesses and ensure that the enterprise is fully prepared and responds to cyber-attacks. Red teamers mostly use various TTPs developed to emulate real-world attacks, often based on the MITRE ATT&CK framework. 

‍

Red teaming involves several techniques, such as performing data exfiltration, moving laterally, deploying malware payloads, launching social engineering attacks, exploiting networks, monitoring peers, detecting insider threats, and so on. In other words, red teamers perform reconnaissance, exploitation, post-exploitation, and reporting and analysis. 

‍

Blue Teaming

‍

The blue team is responsible for defending and protecting the organization from threat actors, including red teams. These security professionals deal with network traffic, address security incidents, and deploy essential security controls to safeguard the business against threats and attacks.

Blue team security professionals not only prevent and react to attacks but also update security controls to make sure that the organization’s cyber defense is resilient. 

‍

Purple Teaming

‍

Purple teams are formed from red teams and blue teams. In other words, they are not separate entities and aim at creating a cooperative sharing process between red & blue teams. 

‍

A purple team not only encourages efficient collaboration and communication between two teams but also among other stakeholders. 

The objective of the purple team is to propose risk mitigation techniques and help continuously improve red teams and blue teams and the enterprise’s overall security posture. 

‍

In a nutshell, red teams carry out simulated attacks, blue teams defend against them, and purple teams create cooperation and collaboration between two teams and help improve cyber defense.

[fs-toc-h2]Why Is The Red Teaming Exercise Important?

‍

Regularly testing your organization’s endpoint and network security is indispensable because sophisticated adversaries change their TTPs every day. AI-powered attacks are increasing by leaps and bounds. Red teamers pinpoint and fix vulnerabilities before they become a big nightmare. 

‍

Red teaming practice is very crucial if your organization has deployed a new IT infrastructure. It will further help you understand the current maturity level of your organization. The subsequent sections elaborate on why red teaming is essential for your business. 

‍

Introducing Change Management

‍

Mergers and acquisitions of new systems can bring new cyber risks and vulnerabilities. The systems must be tested properly before they are introduced into the production environment. Under such circumstances, your organization direly needs red teaming assessments to be performed to address these security issues in a timely manner. 

‍

Performing Regulatory Compliance Assessments

‍

Red teaming practices help your security operations teams and SOC analysts comply with guidelines stipulated in information security standards like the General Data Protection Regulation (GDPR), SOC 2, Health Insurance Portability and Accountability Act (HIPAA), and so forth. 

‍

Improving Incident Response Plan and Disaster Recovery

‍

Whenever you plan to improve your IRP and Disaster Recovery (DR) capabilities, hire red teaming services to uncover existing security loopholes. Your IRP must detect and respond to threats effectively and efficiently. DR procedures must be efficient enough to mitigate impacts and swiftly ensure business continuity.  

‍

Staying One-step Ahead of Modern Adversaries

‍

Red teaming services offer proactive cybersecurity defense. Instead of reacting to the attack, red teamers enable cyber defense to proactively identify vulnerabilities and eliminate them before they wreak havoc on your IT infrastructure.
