Breach and attack simulation (BAS) refers to technologies that allow organizations to test their security defenses against simulated

cyberattacks A cyberattack is any offensive maneuver that targets computer information systems, computer networks, infrastructures, or personal computer devices. An attacker is a person or process that attempts to access data, functions, or other restricte ...

. BAS solutions provide automated assessments that help identify weaknesses or gaps in an organization's security posture.

Description

BAS tools work by executing simulated attacks against an organization's

IT infrastructure Information technology infrastructure is defined broadly as a set of information technology (IT) components that are the foundation of an IT service; typically physical components ( computer and networking hardware and facilities), but also vari ...

and assets. These simulated attacks are designed to mimic real-world threats and techniques used by cybercriminals. The simulations test the organization's ability to detect, analyze, and respond to attacks. After running the simulations, BAS platforms generate reports that highlight areas where security controls failed to stop the simulated attacks. Organizations use BAS to validate whether

exercises. BAS is often part of a continuous threat exposure management (CTEM) program.

Features

Key features of BAS technologies include: * Automated testing: simulations can be scheduled to run repeatedly without manual oversight. *

Threat modeling Threat modeling is a process by which potential threats, such as structural vulnerabilities or the absence of appropriate safeguards, can be identified and enumerated, and countermeasures prioritized. The purpose of threat modeling is to provide de ...

: simulations are designed based on real adversarial tactics, techniques and procedures. *

Attack surface The attack surface of a software environment is the sum of the different points (for " attack vectors") where an unauthorized user (the "attacker") can try to enter data to or extract data from an environment. Keeping the attack surface as small a ...

coverage: can test internal and external-facing assets. * Security control validation: integrates with other security tools to test efficacy. * Reporting: identifies vulnerabilities and prioritizes remediation efforts.

Use cases

Major breach attack simulation use cases include:

Validating security controls

Frequent BAS testing helps ensure security controls like firewalls and endpoint detection stay properly configured to detect real threats. Continuous changes to networks and systems can introduce misconfigurations or gaps that BAS exercises uncover. Regular simulations also improve incident response by training security personnel.

Efficiency improvements

Iterative BAS helps optimize detection and response times. It assists teams in tuning monitoring tools and refining processes. Vulnerability patching can also be better prioritized based on observed exploitability versus just CVSS severity.

Assessing resilience

BAS emulates full attack techniques to prep defenses against real threats. Mapping simulations to frameworks like MITRE ATT&CK validate readiness against known adversary behavior. While not as in-depth as red teaming, BAS quickly benchmarks resilience.
