Breach Attack Simulation (BAS)
Advanced Penetration Testing
Breach Attack Simulation or BAS is a new word in cybersecurity but is rapidly gaining in popularity and already proved its effectiveness. Here we explain what it is, its features, and benefits.
What Is Breach Attack Simulation (BAS)?
Breach and attack simulation (or shortly BAS) is a new security technology which allows to automatically find vulnerabilities in your infrastructure. In fact, there is much in common between BAS and Automated Penetration Testing. The new Breach Attack Simulation real-world security verification method combines convenience with useful. It’s one of the most common ways to evaluate the reliability of defense systems, demonstrate possible methods of attacks, identify existing security problems.

Traditional penetration tests require significant share of human participation, are carried out with a certain frequency and in a short time. Their results reflect a static picture recorded at the time of the testing. Breach Attack Simulation is a growing market for tools that perform automated security testing on a regular basis and spend less human time.
Since the BAS technology is relatively new, solutions on the cybersecurity market may differ. There are solutions that concentrate on breach simulation itself. Other solutions may simulate a comprehensive attack with the capability to analyze the enterprise’s response in exploitation and post-attack phases. So, the main problem is what tools to choose for this.
As a good start to implementing your BAS we recommend evaluating your attack surface first with the help of our ImmuniWeb Discovery Attack Surface Management tool.
Why Breach Attack Simulation Is Needed?
Typically, network security testing is associated with two mechanisms: this is the simplest Application Penetration Testing and Red Teaming. Standard pentesting is carried out by individual experts or group of experts that take on the role of hackers trying to penetrate the organization’s information systems and are looking for ways to get to the valuable information. Such a search for ways of penetration shows which vulnerabilities can be the starting point for the actions of attackers, but does not give an idea of how the attack will develop and how successfully the defense system will resist it.
Knowing these limitations, pentesters resort to such automation tools as vulnerability scanners, exploit kits, and more. These are well-established technologies, especially the search for known software vulnerabilities , which even home users can exploit for a long time, since many antivirus vendors include this component in their products. It is relatively cheap and fast, it is easy to automate, and with the help of a large updated database the scanner is able to detect thousands of bugs of any age, up to the most recent and actually used by cybercriminals.
Red Teaming, in turn, is an improvement in simple penetration testing that overcomes some of its shortcomings through a more meticulous, in-depth and realistic test. Specialists conducting such a study reproduce the entire range of actions of attackers aimed at gaining access to the information infrastructure and gaining a foothold in it. Both regular pentesting and Red Teaming exercises are useful for assessing the security of information systems, however, when using them, you need to keep in mind several features due to their nature.
In both cases, security is checked by people manually, although using automatic software tools to facilitate this task. Each check gives a narrow static picture, that is, it shows only the ability to bypass the protection at a single point in time based on one scenario. Both approaches, especially the simple pentest, provide relatively few opportunities for a comprehensive assessment of the effectiveness of the security policy and the security system as a whole.
What Are the Features of Breach Attack Simulation?
According to many experts on cyber security, Breach Attack Simulation is like a penetration test, only better, so a regular pentest will eventually be superseded by solutions from the BAS category. At the same time, Red Team and BAS are not mutually exclusive, in principle, that is, they not only compete with each other, but complement one another. In general, they can be called two paths to one goal. At the same time, BAS has features that allow you to overcome some of the inherent flaws of the Red Team.
Essentially, BAS is an evolution of the traditional penetration testing towards Automated Penetration Testing. Here, the actions of malefactors are still reproduced, however, the human is almost completely excluded from the verification process, since once launched, the testing tool will conduct attacking actions according to the given scenario and will methodically expose the protection system to the entire range of directions and hacking methods until it finds a loophole and will not achieve the desired result. However, as a rule, there is no need to purchase and deploy hardware and software, learn to use exploit packages, and so on.
Breach Attack Simulation usually exists in the form of SaaS cloud service, so it is enough to rent them and activate at the touch of a button. In addition to its greater ease of use, BAS facilitates regular inspections, as it does not require the hiring of experts. For verification, you only need to run an independently working task on a schedule and study the results. The creators of such products often pay particular attention to how reports are generated and test results are presented.
In this way, you can clearly see what each penetration attempt has led to, and draw conclusions about where the protection system should be strengthened. The key idea of this method is to ensure consistent and continuous security checks, automatically simulating many different attack options and allowing you to monitor how people and IT infrastructure respond to threats. Since the Breach Attack Simulation can be inferior to the Red Team method in the subtlety and class of attacks, but, on the other hand, outperforms it due to the breadth of coverage of probable problems, including very exotic ones, so these methods of assessing security complement each other.
Since the Breach Attack Simulation way is relatively new, existing solutions differ significantly in functionality and technology. The vectors of simulated attacks are quite diverse, like their predefined patterns, and some products allow you to assess the level of risk and offer recommendations for eliminating identified threats, taking into account compliance with regulatory. Most solutions are available as a cloud service, some are deployed locally.
Some of the Breach Attack Simulation offers need to install agents, others work without them, but there is a similar range of functions. BAS products allow companies to independently and continuously evaluate their security, check security mechanisms by simulating attacks on various directions. Examples include phishing mailings, modeling cases of leakage of confidential information from the internal network, simulating network attacks, malicious activity.
What You Get from the Breach Attack Simulation?
The system of countering information threats begins with the correlation between the costs of protection and the losses from compromising the protected information and the unavailability of services. If the organization does not need, for example, the processing of personal data or the introduction of a trade secret regime, then the familiar and well-developed method of searching for vulnerabilities will be quite sufficient for it, but provided that the IT department can conduct an elementary pentest, you will have to worry only with major changes in company. In case the stakes are high, then the reliability of security tools will need to be more thoroughly checked, and the more important the data of the enterprise, the less it should rely on classic vulnerability scanners or web applications.
Despite the growing popularity of solutions for automatic simulation of attacks, BAS is unlikely to ever completely replace the traditional pentest. However, products of this type can significantly change the market for practical safety, as they offer a faster and cheaper way to assess security compared to manual penetration testing. Here methods come to the rescue that reproduce the activity of real attackers and make it possible to check the stability of information systems in real time. The Red Team deepens the capabilities of the traditional penetration test, and Breach Attack Simulation automates it, allowing you to keep security under constant control, monitor all key attack vectors at the same time, and also make sure that all information protection tools are configured and function exactly as they should.
As a result, this gives the user more representative test results, since the deeper the analysis and the more regular it is, the more complete our understanding of the reliability of the built protection. Thus, the use of Breach Attack Simulation for continuous security assessment can significantly increase the level of actual security of the company's IT infrastructure.
