Organizations need to stay ahead of attackers as cyber threats evolve constantly. Adversarial simulations, such as Red Team vs. Blue Team exercises are incredibly useful in solving this concern. The “Red Team” simulates a group of hackers attempting to breach the organization’s security, while the “Blue Team” works on mitigating the attack attempts while trying to defend and respond to the breach.

This threat emulation not only customizes the response tactics but also helps the businesses identify areas where they are lacking; resulting in the formation of stronger defenses and fortifications for the future.

Understanding Red Team and Blue Team

Every person assigned a Red Team role aims to penetrate an organization’s infrastructure by exploiting its weaknesses. The goal is to stay ahead of the malicious actor by hacking into systems preemptively before damage can be inflicted. This can be done through penetration testing, social engineering, and APT simulation engagements.

This includes conducting phishing campaigns in order to entice an employee to communicate with a fake source. A Google report reveals that 70% of the exploits last year were zero-day, all the more stressing the need for these offensive approaches.

You concentrate on the fortification and defense of the organization as a Blue Team member. This includes monitoring network activity 24/7, responding to incidents, and managing systems’ vulnerabilities. This is also your focus as their main duties.

The focus has been on firewalls, intrusion detection systems, and even encryption as part of technology implementation to protect networks and data. Frequent assessments and timely security patches are necessary because they help keep systems in place against new threats.

How Adversarial Simulations Help Secure Systems

To comply with risk management measures, many organizations tend to carry out outdated procedures that become ineffective during incidents. Regular adversarial simulations ensure that your response plans do not become stale.

The most important benefit of a cyber security simulation is its ability to expose weaknesses in the system. At the same time, the exercise’s multi-faceted approach can drastically improve the firm’s incident response skills. Such exercises allow participants to train in decision-making and coordination under duress. All these competencies ultimately result in more effective communication during real cyber events.

Simply put, an organization that has not defined its incident response strategies becomes vulnerable to system breaches. Companies that struggle with the consequences of cyber incidents will benefit from regular incident response exercises. Such measures will improve how quickly the company can recover from the incident, and in turn, decrease the time and money needed to solve the aftermath.

Red Team vs. Blue Team in Action

With red-team-blue team exercises, one is bound to strengthen his or her organizational cyber defense. These exercises are a simulation of sorts. One team has a red name and behaves aggressively while another team, blue, plays more defensively. Below, we provide a step-by-step process for doing effective simulations, including details of the strategies used by each team.

Steps in Doing an Effective Simulation

• Planning and Objective Setting: To make the best of the simulation exercises, they should start by setting clear objectives. Determine what systems to put under pressure and what results to achieve.

• Reconnaissance: The Red Team gathers information about the target systems to determine vulnerabilities in the system and possible ways of getting in.

• Exploitation: Using the obtained information, the Red Team tries to break into the system in a manner akin to an attack.

• Detection and Response: The Blue Team waits for suspicious activity from the opposing team and works to defeat the Red Team’s efforts as quickly as possible.

• Debriefing and Analysis: Following the simulation, both teams analyze their performance during the session. Teams to highlight positive outcomes and agree on things that did not work so well.

Common Examples of Tools and Procedures Sometimes Used by Each Team

Red Team Tools:

• Metasploit: This is software that allows someone to write sans and implement an exploit against a targeted machine through powerful features.

• Cobalt Strike: A tool that is great for threat emulation and a multitude of post-exploitation tasks.

• Social Engineering: Phishing and other means designed to trick people into divulging sensitive information.

Blue Team Tools:

• Security Information and Event Management (SIEM): Consolidate and scrutinize activities from various sources to determine possible security risks.

• Intrusion Detection Systems (IDS): Track network data for illegitimate activities and recognized risks.

• Firewalls: Serve as a protective screen between a trusted network and an untrusted one, regulating traffic coming in and out of the network.

Bridging the Gap: The Purple Team Approach

Instead of working separately as Red and Blue Teams, the Purple Team enables more collaborative learning and feedback from real-life scenarios to bridge the gap left by the Blue and Red Teams.

Assumed Attack Scenarios developed by Red Teams are executed and Blue Teams will focus on analyzing insights and bolstering the defenses. This cycle of assessing and revising guarantees that security procedures are continuously improved.

A recent industry survey found that 91% of respondents believe collaboration within security teams is key to improving threat detection and response. This simultaneous data sharing allows both teams to reinforce each other’s standpoints.

How Purple Teams improve overall security posture

In doing so, your security teams will be able to:

• Spot weaknesses earlier and establish better countermeasures.
• Improve attack response times by modifying detection and response plans.
• Effective cybersecurity investments are done by focusing on actual threats rather than hypothesized ones.

Conclusion

Simulating attacks using the red and blue team approach, also known as Adversarial Simulations, is critical in fortifying cybersecurity. Attacking organizations helps the company to identify gaps, rectify them, and improve the general security of the company. The collaboration does not end there. Continuous collaboration together with other organizations ensures that there is a proactive approach toward emerging new threats, which means that the systems and data are more secure.
