Breach and Attack Simulation (BAS) is an innovative approach to testing the resilience of company networks. It allows you to simulate cyber attacks in a controlled environment, meaning you can see how your defenses hold up without risking actual harm. 

Like a fire drill for cyber security, BAS helps identify weak spots before a real attacker can exploit them. Through BAS, for example, you can safely test your employees' responses to phishing emails. 

So, you not only assess the likelihood of an employee falling for such an attack but also gauge the effectiveness of our current security awareness training. You can then tailor more specific educational programs based on the results.

Incorporating BAS into your security strategy means you are not just reacting to threats. Instead, you are proactively seeking them out, learning from each simulation, and strengthening our defenses. The insights gained from these simulations are invaluable, helping you protect your company network more effectively.

How BAS differs from traditional security testing methods

Traditional security testing methods, like penetration testing, have been the backbone of cybersecurity for many years. But they often feel like scheduled check-ups, happening once or twice a year. They're thorough, but sometimes they miss the mark when it comes to keeping pace with the fast-evolving threat landscape. 

That's where breach and attack simulation comes in. BAS offers a more dynamic and continuous approach to testing your defenses.

Penetration testing

A traditional penetration test, for example, is a one-time event—usually planned well in advance. Experts look for vulnerabilities, and they’re incredibly skilled at what they do. 

Yet, once the test is complete, any new threats that emerge afterward might not be assessed until the next scheduled test. BAS flips this script by allowing you to simulate attacks at any time. You can run these simulations weekly, daily, or even more frequently, ensuring you are always on top of the latest threats.

Let’s talk about phishing. Traditional methods might involve sending out test phishing emails twice a year to gauge employee awareness. 

But with BAS, you can launch simulated phishing attacks continuously. This helps you assess how your employees handle phishing attempts in real time and adapt your training programs more effectively. You can catch areas of concern early, improving your overall security posture.

Another key advantage of BAS is its ability to shine a light on internal threats. Traditional methods might not focus as much on these, but with BAS, you can regularly simulate scenarios where an insider threatens your systems. This ongoing testing helps ensure your monitoring and access controls are robust and up-to-date.

BAS essentially allows you to replace the static nature of traditional security testing with a dynamic and proactive approach. You don’t just rely on scheduled tests anymore; you create opportunities to learn and improve every day. This constant vigilance helps you stay prepared, rather than reacting to breaches after the fact.

Types of cyber threats facing company networks

Phishing

This is where attackers try to trick employees into revealing sensitive information. They usually use cleverly disguised emails that seem legitimate. 

With BAS, you can simulate these phishing attacks regularly. This way, you not only test how well your employees recognize suspicious emails but also fine-tune your security awareness training based on real responses.

Ransomware

Imagine waking up to find that critical data is locked up, with attackers demanding a ransom. It's a nightmare for any business. But with BAS, you can simulate ransomware attacks before they happen. 

Through that simulation, you can assess how quickly your systems can detect such threats and how efficient your incident response plans are. That helps you minimize the potential damage when real ransomware strikes.

Insider threats

Whether malicious or negligent, insiders can also pose a considerable threat. They already have access to your network, making it easier for them to cause harm. 

With BAS tools, you can simulate scenarios where insiders attempt to access sensitive information without permission. This type of simulation helps you improve your monitoring and access control systems, ensuring that even trusted individuals have the right level of scrutiny.

Software vulnerabilities

Cyber attackers love to find and exploit weaknesses in your software and applications. By using BAS, you can continuously test your network for such vulnerabilities. You can simulate attacks that specifically target weak spots in your software, ensuring you patch them before attackers get a chance.

Denial-of-Service (DoS) attacks

These attacks can cripple your network by overwhelming it with traffic, making it impossible for legitimate users to access services. By running simulated DoS attacks through BAS, you can evaluate your network's resilience and refine your strategies to mitigate these disruptions effectively.

Each of these threats requires your attention, and BAS allows you to tackle them head-on in a controlled environment. It allows you to stay one step ahead, understanding potential threats, and enhancing your defenses in real time. This way, you are not just waiting for the next wave of attacks—you are actively preparing for them.

How Breach and Attack Simulation works

Breach and Attack Simulation tools mimic real-world cyberattacks. They follow attack paths and vectors that hackers use, drawn from frameworks like MITRE ATT&CK and the Cyber Killchain. 

BAS tools simulate everything from network and infiltration attacks to malware and ransomware threats. It’s like having a virtual sparring partner to train with, preparing you for potential real-life attacks.

When you run a BAS program, you begin by selecting a specific attack scenario from a dashboard. These platforms offer various scenarios based on current threats or even custom-defined situations. They can emulate the tactics of Advanced Persistent Threats (APTs), which are notorious hacker groups that might target specific industries.

Once you have picked a scenario, the BAS tool deploys virtual agents across your network. These agents act like seasoned attackers. They attempt to breach your defenses and navigate through the network to access critical assets or sensitive data. 

These virtual agents even mimic insider threats, using knowledge of your systems that actual criminals might exploit. Unlike traditional methods, these simulations don’t stop at the perimeter; they delve deep into your systems.

After the simulated attack, the tool generates a detailed report. This report highlights vulnerabilities in your security controls, from firewalls to endpoint security. You get insights into your network security controls, email security, access control measures, and more. It even evaluates your incident response protocols. This feedback is actionable, meaning you can jump into remediation mode right away.

With BAS, you are not just guessing where our weak spots might be. You are testing them in a controlled environment. This process allows you to continuously assess and strengthen your cybersecurity posture, armed with insights that simulate both external and internal threats. 

Core components of Breach and Attack Simulation

Attack simulation

1. Selection of attack scenarios

The process begins with selecting specific attack scenarios from a BAS platform's dashboard. Organizations can choose from a variety of attack vectors such as phishing, malware, ransomware, and more. A company might want to simulate a ransomware attack to assess its readiness and incident response plan.

2. Utilization of virtual agents

Once the scenario is chosen, BAS tools deploy virtual agents across the organization's network. These agents emulate the actions of real attackers, attempting to infiltrate systems and move laterally to access sensitive data. They might simulate an insider threat by attempting to gain unauthorized access to confidential files.

3. Simulation of real-world threats

BAS platforms use tactics, techniques, and procedures (TTPs) from known threat intelligence frameworks like MITRE ATT&CK and Cyber Killchain. This ensures that the simulated threats are aligned with the latest methods used by cybercriminals. For example, a simulated phishing attack would employ the same strategies that current attackers use to deceive employees.

4. Comprehensive reporting and remediation

After the attack simulation, BAS tools produce a detailed report that outlines the vulnerabilities discovered during the test. The report offers a prioritized list of remediation steps. For instance, if the simulation exposed a weakness in firewall configurations, the report would provide guidance on how to fortify this perimeter.

5. Continuous testing and improvement

Unlike traditional periodic penetration testing, BAS allows for continuous security posture assessment. Automated and ongoing simulations ensure that defenses are regularly tested against the latest threats. An organization could set up daily or weekly simulations to consistently monitor their network’s resilience.

Benefits of attack simulation

Proactive defense

Organizations can identify and mitigate vulnerabilities before they are exploited in real-life scenarios. For instance, if a simulated phishing attack reveals that many employees are susceptible, the organization can promptly enhance its training programs.

Resource efficiency

Continuous simulation provides comprehensive security testing without the need for constantly engaging external security testers, saving both time and money.

Enhanced incident response

By regularly testing response plans through simulations, organizations can refine and optimize their procedures, ensuring a swift and efficient reaction during actual cyber incidents.

Breach simulation

Breach simulation gives you a sneak peek into potential cyber disasters before they happen. It allows you to safely simulate breaches in a controlled environment. This way, you can see how your systems would respond without exposing your systems to real danger. Think of it as a rehearsal for a cyber crisis.

Let's say, for instance, you want to assess how well your network can handle a data breach. With BAS, you can simulate a scenario where a hacker attempts to steal sensitive information. You set up the simulation by choosing this specific scenario on your BAS dashboard. 

Then, virtual agents, acting as hackers, are unleashed within your network. They try to bypass security controls, much like a real attacker would do. For example, they may attempt to extract customer data, mimicking tactics used in actual data breaches.

These virtual agents follow the same paths a hacker might take, trying different techniques to gain access. They might try to exploit weak passwords or leverage unpatched software vulnerabilities. By doing this, you can pinpoint exactly where our defenses might fall short. 

For instance, in one simulation, you might discover that a neglected software patch opened a door for these agents, highlighting a critical area that needed immediate attention.

After running the breach simulation, you are presented with a detailed report. This report outlines the vulnerabilities that the virtual agents uncovered. It’s like getting a roadmap of where your weaknesses lie, complete with prioritized steps for remediation. 

For example, if you found that your firewall rules were too lax, the report would include specific recommendations to tighten them. It essentially gives you a playbook for strengthening weak spots in your security.

One of the main advantages of breach simulation is the ability to continuously test and refine your defenses. Unlike traditional methods where tests are conducted infrequently, BAS lets you run simulations regularly. 

You could decide to simulate a breach weekly or monthly, keeping you on your toes and ensuring that your systems are always ready to handle the latest threats. This regular testing is essential because it keeps your incident response strategies sharp and well-practiced.

By simulating breaches, you can also assess your team's response to potential incidents. This helps you evaluate whether your incident response plans are solid or need tweaks. 

For example, during a simulation, you might find that your response time is slower than ideal. This insight allows you to make necessary adjustments, ensuring you are better prepared for a real breach.

Breach simulation, therefore, provides you with valuable insights, helping you not just react to threats but preemptively address them. You stay a step ahead and are proactive in your cybersecurity efforts.
