Breach and Attack Simulation (BAS) Guide

Breach and Attack Simulation (or BAS) is a method of testing the security of an organisation’s IT infrastructure by simulating an attack on it. The purpose of this type of testing is to identify vulnerabilities in your system before they are exploited by real-world hackers, who may attempt to gain unauthorized access to your network or data.


The process of simulating cyber-attacks can be conducted either manually or through the use of automated tools, with the understanding that some degree of compromise is likely to occur. However, this outcome should not be viewed as unfavourable. In fact, instead of being subjected to actual cyber threats from criminals who seek to profit by stealing sensitive information, the simulation provides an opportunity to evaluate the resilience of your systems against simulated attacks from external entities.

Types of Breach and Attack Simulation

There are three types of BAS:

  • Network

  • Application

  • Endpoint (or end-user)


Network Breach and Attack Simulation is a type of testing done to determine the security posture of your network, including its devices and protocols, as well as any vulnerabilities that may exist in those areas.

The second type is Application Breach and Attack Simulation. This kind of testing focuses on applications that run on your system- both internally developed ones as well as third-party ones- to see if they’re secure enough to protect against hackers or malicious users who want access to sensitive data stored within them.

Finally, there’s Endpoint (or end-user) Breach and Attack Simulation: this involves examining how well users follow security policies when accessing sensitive information; if they don’t follow those policies then it could lead directly into an incident such as identity theft or data loss due to unauthorised access by someone else who shouldn’t have been able to get their hands on this information.

Benefits of Breach and Attack Simulation

There are a number of benefits to Breach and Attack Simulation, including:

  • Improved Cybersecurity Posture: By simulating attacks on your organisation’s cybersecurity systems, you can identify areas that need improvement. This allows you to make changes before an actual attack occurs and potentially reduces the impact of any future breaches.
  • Faster Detection and Response: When an actual breach occurs, it may take weeks or months for IT staff members to identify all affected systems and users because they will have no idea what they’re looking for. With simulated attacks, this process can be streamlined so that security teams know exactly where their attention needs to go when responding to incidents in real life (or at least as close as possible).
  • Reduced Cost of Security Solutions: If there are certain aspects of your current security solutions that aren’t working well enough- such as false positives or missed alerts- then those issues will become apparent during simulation exercises rather than after an actual incident has occurred. You’ll then be able to make adjustments before spending money on new equipment or services which would otherwise have been wasted on ineffective solutions.

Common Challenges of Breach and Attack Simulation

There are many challenges to Breach and Attack Simulation, but the most common include:

  • Lack of Realistic Simulations. This can be due to a lack of understanding about what makes an effective test and how to conduct one, or it may be because the tools used for simulation do not accurately reflect real-world conditions.
  • Difficulty Identifying Weaknesses in Your Security Posture. If you don’t know where your weaknesses are, how can you fix them? This is where good data comes into play- you need it in order for your tests (and their results) to be meaningful and actionable on an organisational level.

Breach and Attack Simulation is a powerful tool that can help you gain visibility into your organization’s risk profile. By leveraging best practices for maximum benefit, you can make informed decisions about how to address the gaps in your security posture.

To choose the right solution for your needs, it’s important to consider several factors:

  • How much time do I have?

  • What are my budget constraints?

  • How many resources do I need to dedicate to this project?
