This article outlines how an attack surface analysis works as well as the details that go into such an analysis. Attack surface analysis is a general outline and hands-on tool used to identify and define vulnerabilities within systems by clearly mapping out how systems function, what services they use (web forms, APIs, etc.) and assessing where they are most vulnerable. This is followed up by creating controls and implementing them to prevent attack. I gathered from the article that the analysis is sort of a living document, as the article instructs the user to adapt and modify their analysis and understanding as their organization evolves and incorporates more services. This is very in-keeping with a lot of IT systems, as our means of control must evolve with new technology and services to meet the challenges they may face in modern times
I agree with you Andrew, once you know the areas of vulnerability it is easy to pick and implement relevant security controls to protect your asset. Without conducting a thorough assessment of the attack surface, certain areas may be overlooked, leading to unaddressed risks.
In the article “Attack Surface Analysis Cheat Sheet” the author delves into attack surface analysis, which involves identifying and properly managing the application’s attack surface to protect applications from external attacks. Application’s Attack surfaces refer to all the potential entry points or vulnerabilities that attackers could exploit to compromise the application’s security. Attack surface Analysis involves mapping out what parts of a system need to be reviewed and tested for security vulnerabilities. To properly manage the attack surface, it is important to identify the points of entry and exit on the system as these are the points where data comes in and out of the network. Identifying high-risk areas can help developers defend and learn how they can reduce these risks properly. To make the attack surface more manageable it can be broken down into different types based on their functions such as log/authentication, data entry, logout/ point of exit, and so on. Additionally identifying the type of data being stored on your system is very crucial
The article elaborates on effective strategies for managing the attack surface. Developers should track all the changes that are made, whenever new features are added to an existing application and proper risk assessments should be done to understand all the security issues that come up with added features. Another option to consider is disabling any of the features that will not be used, reducing the number of user levels, and not storing confidential data unless necessary. Understanding the attack surface is crucial because it helps identify and mitigate potential vulnerabilities, reducing the risk of cyberattacks.
The concept of reducing the attack surface by disabling unused features, minimizing user levels, and avoiding unnecessary storage of confidential data is closely related to several of the OWASP Top 10 security risks:
A01:2021-Broken Access Control: Minimizing user levels can help prevent unauthorized access and ensure that users have permissions appropriate to their roles, addressing potential broken access control issues.
A02:2021-Cryptographic Failures: Not storing confidential data unless absolutely necessary can reduce the risk of cryptographic failures that might occur if sensitive data is exposed.
A05:2021-Security Misconfiguration: Disabling unused features can prevent security misconfigurations, which often result from unnecessary features that are not securely configured.
A06:2021-Vulnerable and Outdated Components: By turning off features and interfaces that aren’t being used, the risk of using components with known vulnerabilities is reduced.
These actions align with the principles of proactive security and risk management emphasized in the OWASP guidelines. By understanding and managing the attack surface, developers and security specialists can create more secure applications by design, which is a fundamental aspect of modern cybersecurity practices.
This was an interesting article and saved it in my favorites. I like how it breaks down the total number of attacks by different types based on function, design, and technology as there are easily thousands of attack points. Some of these attacks pointed sections can be login entry pointes, admin interfaces, search functions, business workflows etc. It also shows how you can use different scanning applications like OWASP ZAP or Arachni which are just a pair or what is out there of many commercial testing and vulnerability scanning tools. This article starts to give me an idea on how cyber professionals work on a day-to-day basis. You can also track attack surface of an application and track changes to the attach surface itself overtime by using relative attack surface quotient (RSQ) which is a method you use to calculate an overall attack surface score from the system and how you measure the score as changes are made to the system and how it is deployed. When you are ready to manage the attack surface and have a foundation of understanding the attack surface, it will then help you identify and manage risk going forwards as you can then adjust the applications. As you do this the article points out several questions that you should ask yourself as you will need to understand how it changes, are you doing differently and what holes you could have opened. I really enjoyed this article and saved it in my favorites as there are many other ones you can read and will come in handy for my presentation.
Hi Jeff,
Truly speaking there are likely tons of attack sites, therefore I appreciate how it divides out the overall number of attacks by different sorts depending on function, design, and technology. Sections that are vulnerable to assaults include admin interfaces, search functionality, business workflows, and login entry points. This helps to give proper perspective to these attack vectors.
Breaking down attack surfaces based on functions and technologies can help prioritize vulnerabilities. Using tools like ZAP and Arachni for analysis is recommended, which empowers a proactive approach to security. The concept of Relative Attack Surface Quotient (RSQ) for tracking changes is insightful. It allows you to measure progress as you secure the application. Understanding how the attack surface evolves is critical to continuous risk management.
Good points Jeff. I agree that this article does a good job contextualizing the actions that security experts take in their every day work.

The document mentions how attack surface analysis can help you in several ways by identifying what functions and what parts of the system needs testing. It also can identify high risk area that need defense in depth protection as well as when to change the attack surface.
Identifying and Mapping the Attack Surface section helps you to start building a depiction of the Attack Surface using notes and pictures. You are encouraged to design your architecture documents from a hacker’s perspective. This stood out to me because sometimes we approach technical issues and documents from a defense standpoint, where we should try to think like a hacker. Where are the weaknesses in your plan how can they be exploited? These are important questions, so your design must be able to answer them while providing a solution.
Erskine, you are right about the cheat sheet simplifying the process of conducting attack surface analysis and providing developers with a practical tool to identify vulnerabilities within their systems. By highlighting the importance of understanding what functions and parts of the system require testing, the document emphasizes the proactive approach needed to mitigate risks effectively.
The OWASP attack surface analysis cheat sheet is an essential tool for understanding and protecting your web application’s vulnerable points. It explains what an attack surface is and why it’s crucial to identify it. By following this cheat sheet, you can analyze your application and find potential entry points that attackers might exploit. This analysis helps you identify weaknesses and prioritize security measures. Think of the cheat sheet as a roadmap for identifying and mitigating vulnerabilities in your web application, making it a valuable tool for developers and security professionals alike.
This is exactly how the document is intended to be used. By providing a basic step-by-step procedure for developers and security professionals to understand the attack surface of an application, the process can become more streamlined and it becomes much easier to develop a plan for managing the attack surface.
Hi Kelly, I agree that the OWASP cheat sheet is really important for keeping web apps safe. It helps find and fix weak spots where hackers might try to break in. I think of it like a map that shows you where to look for problems and how to make them better. It’s useful for anyone making or protecting websites, helping them stop attacks before they happen.
Mapping the attack surface can be a very useful technique for those responsible for vulnerability analysis and application security because it effectively replicates the procedure that an attacker will use to compromise an application. According to OWASP, persons responsible for safeguarding online apps must guarantee that no injection points exist. They also need to examine the security of file uploads, as an attacker can upload a reverse shell on a web server if it is not protected against this type of attack. Web shells can be hidden by using double or altered file extensions, so any type of file upload requires extra security precautions.
Although anyone can guarantee that there are no entry points to an application, realistically there is always a gap waiting to be exploited by someone highly motivated/skilled enough to do it. Ultimately, by understanding the attack surface of an application, not only can there be mitigations to potentially existing problems, but also preparations in the event that some part of the application is breached.
This article provides insight into Attack Surface Analysis, a critical aspect of application security risk management from a developer’s perspective. The focus is on understanding, identifying, and mitigating potential vulnerabilities within an application’s attack surface.

Hi Alex, The document is designed effectively to provide insight into the attack surface. Given that this is a profession where information is constantly changing, I wonder what the process will be when it comes to updating this document. How would something like AI shape protection from external attacks? or even system monitoring. Would there ever be a situation where a document like this would have to be updated numerous times a year? and how big of a change would have to happen in order for it to be considered to update the document? Just because a new threat is created doesn’t necessarily mean it can cause massive damage either, sometimes a new threat is something that’s mild or isn’t bad enough for it to be seen fit to patch it.
The article provides information about how attackers can gain access to the applications and also ways to address it. It guides by identifying entry points, data flows, and testing of applications for threats. By implementing OWASP Attack Surface Cheat Sheets, organizations can strengthen their systems and mitigate the risk of being exploited by attackers.
Developers, in any sector, use many tools to assist them at work. Whether it be online forums, websites, or open-source software, they will use whatever they have at their disposal. The attack surface analysis cheat sheet is another example of this. Intended for developers, this document helps them understand/manage application security risks when they design and change said application. This would be if their intention was protection from external attacks. This Analysis helps identify functions and parts of the system that need to be reviewed and tested for vulnerabilities and identify high-risk areas of code that need specialized protection. Different parts that are to be analyzed are Files, Databases, headers and cookies. It should be noted that there may be other areas to analyze, and that this document should more so be used as a reference rather than a perfect rubric to use for assessing.
The OWASP Attack Surface Cheat Sheet, from the Open Web Application Security Project, is a comprehensive guide for developers and security professionals. It aids in assessing potential vulnerabilities in web applications by analyzing data inputs, authentication mechanisms, external dependencies, configuration settings, error handling, code quality, and business logic. This tool promotes understanding of all possible entry points that could be exploited by attackers, helping to prevent security breaches. By promoting secure practices, such as validating user inputs, securing authentication, managing configurations, and protecting business logic, it encourages a proactive approach to web application security. This helps organizations build resilient and secure software systems.
Hi Ikenna,
I agree with you that proactive measures such as validating inputs, strong authentication methods, and the right configurations help to secure web applications. By implementing the measures effectively, organizations can harden their web applications to avoid unauthorized access or data manipulation.
This article, the Attack Surface Analysis Cheat Sheet, is a document that outlines a simple way to conduct attack surface analysis and manage an application’s attack surface. The intention is for developers to use the document to understand and manage application security risks throughout the SDLC and for application security specialists to use during security risk assessments. The main focus is on protection from external attacks, it will not assist in internal threats or account attacks from users of the system. One of the most important aspects of the document I took note of is the process of mapping and identifying the attack surface of an application.
This process comes down to spending hours reviewing design and architecture documents from the point of an attacker: this means examining source code and looking for entry/exit points like UI forms, HTTP headers/cookies, APIs, Files in use, Databases, etc. In larger applications, this can be very difficult to manage so it can broken down and categorized into some of the following: Login/authentication entry, admin interfaces, inquiries/search, CRUD forms, etc. Data that is in use should also be noted based on how valuable the data is and how it is used in the system. There are also tools that can assist in scanning applications to develop an attack surface and can be validated by walking through the process of an average user and seeing the flow of data and processes involved.
