Breach and Attack Simulation: How it helps Improve Security?

According to the FBI’s Ransomware Prevention and Response for CISOs, “on average, more than 4,000 ransomware attacks have occurred daily since January 1, 2016. This is a 300-percent increase over the approximately 1,000 attacks per day seen in 2015.” That means, there is a three-fold increase in ransomware attacks, and it is just one type of cyberattack. There are more types of cyberattacks, i.e., there is a rocketed risk of cyberattacks and other threats for organizations.

With the rising cyberattacks, every organization must implement cybersecurity solutions to counterattack the growing threats. But, how does your organization confirm its security shield works? After all, you cannot test your security solutions without the right tool — a toolset called breach and attack simulation. That said, let’s get to know it to understand its part in improving security.

What is Breach and Attack Simulation?

Breach and attack simulation is a set of technologies that “allow enterprises to continually and consistently simulate the full attack cycle (including insider threats, lateral movement, and data exfiltration) against enterprise infrastructure, using software agents, virtual machines, and other means,” per Gartner.

That is, breach and attack simulation (BAS) is a toolset to simulate cyberattacks on your organization to test your defenses. Of course, its benefits sound similar to the benefits of penetration testing or white-hat hacking; so the question arises: why should an organization opt for Breach and Attack Simulation?

What is the benefit of breach and attack simulation? The feature that makes it stand out among other security testing solutions is its ability to continuously and consistently testing your organization’s defenses with limited risks. Then, it validates your business’s security infrastructure and detection and prevention technologies. Moreover, it helps address the executive decision-makers about the existing security gaps and suggests the best set of security solutions.

That is not all; breach and attack simulation, if complemented with penetration testing or red team exercises, assists in detecting the efficiency of the security teams of your organization in detecting and mitigating security attacks. But of course, you and your organization must act on the reports, work on filling the security gaps, and improve the security infrastructure else it proves useless. So, it is as important to work on the findings as it is to implement BAS itself.

These tools promise to pretend to perform things similar to what the attackers will do (such as lateral movement, exfiltration, privilege abuse, perhaps exploitation, etc) in order to test how well your security controls (prevention, detection, response) work. Naturally, if you are not able to act on the findings, these tools will not do you any good, just like the pentests people [occasionally] ignore,

wrote Anton Chuvakin, a member of the Gartner Blog Network.

How does BAS help Improve Security?

Though there are numerous security advancements, the hard reality is it is hard to keep up with cybercriminals since they are relentless at trying out new techniques to breach your organization. The best methodology to harden your organization’s security infrastructure is to execute or run cyberattacks.

However, there is a flaw with the security validation procedures: the penetration testing performed by the pen-testers are as good as their skills and time. So, the efficient way to fix this flaw is to automate and execute the techniques used by cybercriminals using breach and attack simulation tools and techniques.

Of course, it removes the human variable of those attacks or simulations, but it helps keep pace with the newest hacking methods and ever-changing enterprise networks. Then, it can assist your organization to make better vulnerability management investments. Moreover, you can test your improved security infrastructure with breach and attack simulation. For example, if you have recently applied patches for crucial vulnerabilities (let’s say, Intel’s bugs named Meltdown and Spectre), you can use breach and attack simulation to run attacks on those vulnerabilities and check the effectiveness of the applied patches.

Additionally, there are more benefits of using breach and attack simulation to harden your security infrastructure. First of all, BAS helps test your security infrastructure at regular intervals — continuously and consistently. Then:

1] Highlight Gaps in Security Posture

Though your organization may have an expert security team, there may be gaps in their security posture. After all, there are too many layers of security, many products to monitor and secure, and too much configuration that may hinder the most efficient teams from staying in sync, seeing the number of odds.

Moreover, there are too many unknown variables in simulating cyberattacks that a team can cover everything every time. With breach and attack simulation, your security team can cover all known and unknown variables since the attacks are automatically performed — continuously and consistently. Your organization is better prepared and protected with breach and attack simulation tools since they find, report, and help fill the holes in the organization’s infrastructure.

2] Prioritize the Future Investments

Without breach and attack simulation technologies, your organization works in the dark. Either your security infrastructure works or it does not on the day when cybercriminals attack your organization. In either case, the executives or decision-makers cannot make sure their investments are doing good.

With BAS, you know if your present investments are paying off. Then, you also get to know the security holes, so you know the bad investments (or the bad security solutions). Moreover, it helps understand the organization’s security posture, allowing you to prioritize future investments for the best results.

3] Verify Existing Security Controls

As it is discussed, breach and attack simulation helps test the organization’s infrastructure including its security controls. Since the environments including the software and security tools have grown highly complex, it is not uncommon to find a difference between the expected and the actual outcomes.

After designing and setting up defenses, breach and attack simulation helps test those defenses, making sure of their strengths and reporting their weaknesses — continuously and consistently. Also, BAS suggests improvements to harden your organization’s security by updating the configuration of existing controls.
