Attack surface analysis is a cybersecurity technique that aims to identify and provide an understanding of the exploitable vulnerabilities present in a digital environment and its connected IT infrastructure.
The process typically starts with cataloging all the components and assets within or connected to an application, a system, or a network. These parts are then scanned for vulnerabilities that comprise an organization’s attack surface. Such vulnerabilities include open ports, misconfigured cloud or web services, outdated software, and insufficiently secured third-party integrations.

Attack Surface Analysis: A Deep Dive
How Do You Perform an Attack Surface Analysis?
Attack surface analysis involves the following steps:
1. Asset discovery: The first step is to build an inventory of all the assets in your infrastructure, including domain names, subdomains, IP addresses, applications, cloud services, and more. Automated asset discovery methods can help you create a more realistic and up-to-date asset inventory.
2. Vulnerability detection: Determining which assets can serve as attack entry points is next, such as misconfigured cloud services, dangling DNS records, and others. Vulnerability scanning capabilities and tools can make this process easier and more accurate.
3. Attack vector analysis: Understanding how attackers can exploit each vulnerability happens then. Exploit intelligence and penetration testing are handy at this stage to help you answer questions like:
- What attacks can threat actors perform?
- What systems or data can they gain access to if they succeed?
- What damage can they cause?
Insights from the analysis can pave the way for more advanced attack surface management processes, such as further vulnerability prioritization and remediation.
Why Is Attack Surface Analysis Important?
In its simplest form, attack surface analysis occurs when you map out all the parts of a system that threat actors can exploit. The process is a crucial component of an organization’s overall cybersecurity strategy, as it helps bring to light blindspots and weaknesses. These vulnerabilities can then be remediated, helping thwart cyber attacks that would otherwise slip through the cracks.
Here are some of the specific benefits of the process.
- Vulnerability prioritization and remediation: It helps organizations identify all known weaknesses and remediate the high-priority ones first.
- Efficient resource allocation: Security teams can focus on the most critical and relevant vulnerabilities instead of trying to protect against all possible attacks at once, which would be infeasible, given resource constraints.
- Regulatory compliance: Attack surface analysis, including routine vulnerability assessments, is essential for regulatory compliance in certain industries. Through these assessments and exportable reports, organizations can proactively demonstrate how they have been progressing in identifying and addressing vulnerabilities, potential attack vectors, and security gaps in line with regulatory compliance requirements.
- Faster incident response: Understanding your attack surface enables security teams to diagnose and address issues faster and more efficiently.
Keep in mind that attack surface analysis should be an ongoing process rather than a one-time activity. Your attack surface keeps growing as you add more digital assets and since the threat landscape continuously evolves and leads to new vulnerabilities and exploits. Regularly performing such an analysis is vital in fortifying your cybersecurity posture.
Key Takeaways
