Attack Surface Mapping (ASM) is a security risk analysis process that helps organisations gain visibility into the attack surface of their IT environment. The process involves analysing and mapping out all points of vulnerability or potential entry points for malicious actors. This includes identifying both internal and external threat vectors, as well as assessing the impact of a breach or exploit to an organisation. ASM is designed to increase an organisation’s security posture by providing a comprehensive view of their attack footprint. This detailed risk assessment can assist organisations in developing effective countermeasures and mitigating threats before they occur.

How Does Attack Surface Mapping Work?

ASM involves the comprehensive identification and mapping of both internal and external threats. This includes identifying existing security controls, as well as any potential weaknesses or vulnerabilities in an organisation’s IT environment. To facilitate this process, organisations may rely on automated tools such as vulnerability scanners or manual processes to identify threats. Once identified, the risks associated with each threat vector can  be assessed and prioritised for remediation.

Organisations can also use ASM to identify new attack vectors by understanding the ever-evolving landscape of their cyber security environment. This includes monitoring changes in system configurations, applications, external connections, and third-party services that could create potential entry points for malicious actors.

Benefits of Attack Surface Mapping

There are several benefits associated with adopting an Attack Surface Mapping approach.

1. Enhanced Security Posture: By identifying all possible entry points for malicious actors, organisations can better protect their systems and data against potential cyber attacks.
2. Prioritised Risk Management: Through ASM, organisations can evaluate the severity of potential threats and prioritise their remediation efforts accordingly, focusing on the areas of greatest concern first.
3. Improved Resource Allocation: With a comprehensive understanding of their risk landscape, organisations can more effectively allocate their resources, ensuring that critical vulnerabilities are addressed promptly.
4. Proactive Threat Mitigation: ASM enables organisations to proactively identify and address threats before they can be exploited, reducing the potential impact of a cyber attack.
5. Regulatory Compliance: Various regulatory standards require organisations to conduct thorough risk assessments of their IT environments. Adopting ASM can aid in meeting these requirements and demonstrating a commitment to maintaining robust security controls.

Whats the Difference Between Attack Surface Management & Attack Surface Mapping?

Attack Surface Management (ASM) and Attack Surface Mapping (ASM) are two closely related processes that involve the analysis and mapping of a business’s attack surface. The main difference between the two approaches is that ASM focuses on mitigating risks associated with existing threats, while ASM helps organisations proactively identify new attack vectors. Both processes should be utilised in order to achieve comprehensive visibility of an organisation’s attack surface and ensure optimal security posture.

To summarise, Attack Surface Mapping is a crucial security risk analysis process that provides organisations with the visibility they need to identify and mitigate threats before they can be exploited. By gaining an understanding of their attack footprint, organisations can implement effective countermeasures  and maintain compliance with regulatory standards.

Although Attack Surface Management and Mapping are related, they serve different functions in terms of threat mitigation. It is important for organisations to employ both approaches in order to achieve a comprehensive view of their attack surface and ensure optimal security posture. Doing so will reduce the likelihood of a successful cyber attack and provide peace of mind for your organisation.

Here at DarkInvader, we provide Attack Surface Management features to help businesses identify both internal and external threats as well as assessing the impact of a breach or exploit to their organisation.
