What is Breach and Attack Simulation (BAS)?

BAS platforms allow organizations to simulate real-world cyberattacks to test the efficacy of their defenses. Unlike traditional manual methods such as penetration testing or red teaming, BAS tools provide continuous, automated simulations that evaluate the effectiveness of security controls against a wide range of attack vectors.

Key Features of BAS Platforms:

Automated and Continuous Testing: BAS platforms operate autonomously to simulate attacks, providing organizations with real-time insights into vulnerabilities and misconfigurations.
Simulation of Real-World Attack Vectors: These tools simulate various types of attacks, including lateral movement, privilege escalation, phishing, malware injection, and password spraying.
Contextual Risk Insights: BAS platforms prioritize vulnerabilities based on their potential impact, offering actionable guidance on how to mitigate the most critical risks.
Comprehensive Coverage: BAS tests external networks, internal infrastructures, endpoints, cloud environments, and email systems, ensuring a complete security assessment.

Use of BAS for Infosec Teams

Infosec teams use BAS tools to continuously validate security controls across the entire infrastructure. By automating attack simulations, BAS tools reduce the manual overhead of traditional assessments, allowing teams to focus on remediation and improving incident response.

BAS provides infosec teams with:

Continuous security validation, ensuring that defenses are always tested against the latest threats.
Improved incident response, helping teams respond to evolving threats faster by regularly testing response strategies.
Customizable attack scenarios, tailored to specific environments to reflect industry-specific threats.

What Does Gartner Say About Breach and Attack Simulation?

Gartner highlights the importance of BAS tools as a proactive solution for organizations to continuously assess their security posture. Gartner points out that BAS tools enable a shift from reactive to proactive threat detection, with key advantages such as automated risk identification and continuous validation of security controls. The ability to prioritize vulnerabilities based on risk levels is another key benefit, ensuring that organizations can focus on mitigating the most critical threats first.

How Do BAS Tools Work? (Technical Breakdown)

BAS platforms simulate attack vectors using a variety of techniques, closely mimicking the behavior of real-world attackers. Here's a detailed breakdown of how these tools operate:

Reconnaissance and Discovery:
- OSINT (Open-Source Intelligence): BAS tools gather data from publicly available sources to map out external assets and identify potential attack surfaces. Tools automatically enumerate subdomains, open ports, exposed services, and more.
- Network Mapping: BAS tools use protocols like ARP, ICMP, SCTP, and multicast to discover live hosts within internal networks. They test segmentation and identify vulnerabilities that could allow lateral movement.
Attack Simulation:
- Credential Attacks: BAS platforms automate credential stuffing and password spraying to test the strength of internal and external defenses. Platforms like Pentest Copilot Enterprise go further, simulating GPU-enabled password cracking to validate password policies and protect against brute-force attacks.
- Phishing Simulations: BAS platforms generate custom phishing campaigns, using AI-driven tactics to craft highly targeted emails. These simulations test employee responses and collect data on how well phishing defenses are performing.
- Lateral Movement: BAS tools simulate techniques to move across compromised hosts, testing internal security controls like segmentation and containment strategies.
- Privilege Escalation: BAS tools attempt to escalate privileges by exploiting Active Directory misconfigurations, including multi-relay attacks using protocols like SMB and HTTP.
Post-Exploitation:
- After initial compromise, BAS tools simulate post-exploitation activities like dumping credentials from SAM files, performing memory scraping, or launching Man-in-the-Middle (MitM) attacks to gather additional intelligence.
- Remote Code Execution (RCE): BAS platforms often simulate RCE attempts to assess the impact of discovered vulnerabilities.
Dynamic Attack Graphs:
- Platforms like Pentest Copilot Enterprise visualize attack paths using dynamic attack graphs, where each branch represents an exploitable vulnerability. These graphs help security teams understand the potential chain of attacks and prioritize remediation based on the risk of exploitation.

How Does BAS Differ from Other Cybersecurity Testing?

BAS vs. Vulnerability Assessment and Penetration Testing (VAPT)

Aspect	BAS	VAPT
Automation	Fully automated and continuous.	Manual testing by security professionals.
Scope	Simulates multiple attack vectors continuously.	Specific systems or applications are targeted.
Cost	Lower due to automation.	Higher cost due to manual work.
Complexity	Predefined, real-world attack scenarios.	Custom attack scenarios crafted by experts.

BAS continuously assesses multiple attack surfaces, while VAPT is a periodic, manual process with a narrow focus.

BAS vs. Vulnerability Scanning

Aspect	BAS	Vulnerability Scanning
Automation	Fully automated attack simulation.	Automated scanning for known vulnerabilities.
Insight Provided	Provides attack exploitability and remediation advice.	Identifies potential vulnerabilities but offers no context on exploitability.
Scope	Simulates attacks across network, endpoints, email, and more.	Limited to known vulnerabilities in specific systems.

BAS goes beyond scanning by simulating actual attacks to determine how vulnerabilities could be exploited.

BAS vs. Red Teaming

Aspect	BAS	Red Teaming
Automation	Fully automated simulations.	Manual, creative attack strategies.
Scope	Covers multiple attack surfaces.	Focuses on high-value targets and bypassing defenses.
Frequency	Continuous, 24/7 testing.	Periodic, usually annual or bi-annual.

Red teaming involves sophisticated, manual attempts to bypass security controls, whereas BAS provides continuous, automated testing across a broader range of attack vectors.
