Your organization’s attack surface is the collection of all external points where someone could potentially penetrate your corporate network. Think of your attack surface as any opportunity or vulnerability that a malicious agent could use to gain access to your IT infrastructure. A large attack surface contains multiple points where an unauthorized person can access sensitive data such as financial records, employee and customer personally identifiable information (PII), confidential product or sales information, and more. Reducing your digital footprint, limiting external access points, and strengthening authentication requirements are the best ways to enhance your security posture and reduce risk.
This reading material describes what the attack surface is and why organizations should focus on it. The definition of an attack surface is the most important component. The attack surface shows where a vulnerability may exist in an application. To define an attack surface, you must first identify the entry point. This can be an API, UI form field, etc. You then need to identify valuable data points and their locations. This will show which areas of the application should be most heavily protected. Finally, testers should spend time trying to “crack” the application. They should perform some of the main functions, such as creating an account or placing an order. For example, when they place an order, they should see what happens if they don’t have a credit card at checkout. Obviously, if this happens, the order should not go through, but it is important to make sure that the application can perform basic functions correctly.
The attack surface includes all of an organization’s networks, systems, applications, data, and people, which are potential targets. The goal of attack surface analysis is to understand an organization’s vulnerabilities and risks so that appropriate measures can be taken to reduce the attack surface and prioritize the most pressing security issues.
When performing Owens attack surface analysis, the following steps are considered: Identify the attack surface; Assessing vulnerability; Determining risks; Priority ordering; Develop safety measures; Monitoring and response; Continuous improvement.
The OWASP Attack Surface Analysis Cheat Sheet is a guide developed by the Open Web Application Security Project (OWASP) to assist organizations in identifying and prioritizing the attack surfaces of their web applications and systems. The attack surface represents the collection of points where an attacker can potentially interact with a system, either to extract data, execute unauthorized code, or otherwise compromise the security of the system.
The cheat sheet is designed to be a practical tool that security teams can use during the planning and execution of security assessments, including penetration testing, vulnerability scanning, and risk-based security programs. It provides a framework for organizations to structure their attack surface analysis efforts and ensure that important security considerations are addressed.
This book describes what the attack surface is and why organizations should care about it. The definition of the attack surface is the most important component. Your attack surface shows you where vulnerabilities may exist in your application. To define the attack surface, you must first determine the entry point. This can be an API, UI form field, and so on. Then, you need to identify the valuable points of the data and where they are located. This will show you which areas of your application should be protected the most. Finally, testers should spend time trying to “hack” the application. They should perform some major functions, such as creating accounts or placing orders. Multiple versions or keeping older versions of an application or code for reasons of future use can also increase the attack surface.
The OWASP (Open Web Application Security Project) Attack Surface Analysis Cheat Sheet provides guidance and best practices for identifying and assessing the attack surface of web applications. The attack surface refers to all the points in a system that are accessible to potential attackers, including entry points, interfaces, and functionalities that could be exploited to compromise security.
The OWASP Attack Surface Analysis Cheat Sheet is a practical tool developed by the Open Web Application Security Project (OWASP) to assist organizations in identifying and prioritizing the attack surfaces of their web applications and systems. This cheat sheet serves as a valuable resource for security teams during the planning and execution of security assessments, such as penetration testing, vulnerability scanning, and risk-based security programs. By providing a structured framework, it ensures that critical security considerations are addressed and organizations can effectively analyze and mitigate potential vulnerabilities within their systems. The attack surface, which represents the points where an attacker can potentially interact with a system, is a crucial aspect of web application security, and the cheat sheet provides organizations with the tools and guidance necessary to identify and prioritize these surfaces for maximum security.
Attack Surface Analysis cheat sheet is used to describe the attacks surfaces within applications. It is used by the developers to understand and manage the application security risks while developing and changing the application. The focus of this documents is to protect the applications from the attacks occurring from the outside of the organization. It helps developer and security specialist to identify they area of risk and mitigate it. In addition, the attack surface analysis helps identify which part of the system needs to be review/test for the security vulnerability.
This reading describes what an attack surface is, and why an organization should care about it. The definition of the attack surface is the most important component. Your attack surface shows you where the vulnerabilities may be in your application. To define your attack surface, you must first identify the points of entry. This can be things like APIs, UI form fields, etc. Then, you need to determine the valuable points of data and where they lay. This will show which areas of your application should be the most heavily protected. Finally, testers should take time to try and “hack” the application. They should do some of the main functions, such as creating an account or placing an order. When they place an order, for example, they should see what happens if no credit card is put in when checking out. Obviously, if this happens the order should not go through, but it is important to ensure the application can perform the base functions correctly.
Attack Surface Analysis involves identifying and assessing various paths and points in a system where security vulnerabilities may exist, as well as the code and measures protecting these paths and points. In an application, the attack surface includes the paths for data/commands into and out of the application, the protecting code for these paths, valuable data used in the application, and the code protecting this data. The process entails grouping and counting attack points to determine the focus of security assessments and continuously refining the understanding of the attack surface through threat modeling. For microservice and cloud-native applications, attention should be given to components reachable from external sources, potentially located behind layers of proxies and load balancers. Open-source tools like Scope or ThreatMapper can aid in visualizing the attack surface. Establishing a baseline description of the attack surface involves reviewing design documents, source code, and identifying different entry/exit points such as UI forms, APIs, files, databases, etc. These points are categorized based on function, design, and technology, and valuable data within the application is identified through interviews and code reviews. The understanding of the attack surface is further refined by scanning the application, analyzing design documents, and conducting threat modeling.
The OWASP Attack Surface Analysis Cheat Sheet offers guidance on identifying and reducing the attack surface of an application or system, helping security professionals and developers understand the various components and entry points that attackers can target. It outlines steps for analyzing an attack surface, including identifying assets, mapping trust boundaries, assessing entry points, and reducing the attack surface through secure design and configuration practices. Following the recommendations in the cheat sheet can strengthen organizations’ security posture and reduce the risk of successful cyber attacks.
The “Managing Application Attack Surface” guide aims to assist developers in understanding and managing security risks related to designing and altering applications. This involves a comprehensive security risk assessment conducted by application security experts to prevent malware injection. It’s important to note that the internal attack surface can be more hazardous than the external one, as privileged users may have extensive access rights.
This article describes in detail the four key steps of attack surface analysis. First, the attack surface of an application needs to be clearly defined, i.e., potential weaknesses that can be exploited by attackers are identified. Next, the identified attack surfaces are meticulously categorized and mapped to reveal their correlations and distributional characteristics. Then, the potential threat of each attack surface is quantitatively analyzed through measurement and assessment to better understand the risk profile. Finally, effective management strategies are developed for these attack surfaces to reduce potential security risks.
In this article, I have paid particular attention to the importance of security risk assessment. This step is critical for organizations because it helps them accurately identify key risk points in their applications. By assessing these risks in depth, organizations can establish the proper controls to ensure the security and stability of their systems. This risk assessment not only provides a clear direction for an organization’s security protection, but also provides a solid cornerstone for future security strategy development.
The definition of attack surface analysis, which includes defining, identifying, mapping, measuring, evaluating, and controlling the attack surface of an application, is provided by this cheat sheet. Attack surface analysis is the process of examining and evaluating security flaws in systems. The main goal is to identify the application’s risk areas, determine which sections are open to assaults, and devise countermeasures. Consider the best times and strategies for implementing the changes, and weigh the risks. Once you are aware of the attack surface, you can utilize it to recognize and control the risks associated with modifying your application.
The core goal of attack surface analysis is to map the path in and out of the system, look at the system from the attacker’s point of view, find the most vulnerable parts of the system, in order to attack the system, steal something or perform other unauthorized operations, the attacker needs to find a way or a certain channel. This change of perspective is very beneficial for us to prevent hacker attacks. The four steps of attack surface analysis are: 1. Define the attack surface of an application 2. Identify and map the attack surface 3. Measuring and assessing the attack surface 4. Manage the attack surface.

The OWASP Attach Surface Analysis Cheat Sheet provided a complete list of items for securing applications. According to the cheat sheet, network-facing code, web forms, files from outside of the network, backward compatible interfaces with other systems, APIs, and security codes are all attack surfaces. Multiple versions or leaving the older versions of application or code for the reasons of future utilization also increases the attack surface.
Protecting an application from external attacks is the main focus of attack surface analysis, and to find out what part of the system needs to be evaluated and tested for security exposures. The attack surface explains all of the different points where attackers can get into a system, and how they may be able to get the data out. Understanding the risk areas in an application is needed in order to make security specialists aware of what parts of the application are open to attack, and find ways to reduce the attempts.
1. The OWASP memo sheet series is designed to provide a simple and practical collection of attack surface analyses and management application attack surfaces. Attack surface analysis is the process of determining which parts of a system need to be examined and tested for security vulnerabilities, and can be used by developers and security professionals to mitigate associated risks. The process of attack surface analysis is divided into several steps: defining an application’s attack surface, identifying and mapping the attack surface, measuring and evaluating the attack surface, and managing the attack surface.
2. Attack surface management is a hot topic today. Attack surface management is an asset security management method that detects and discovers the attack surface of enterprise digital assets from the attacker’s point of view, analyses and researches the attack surface, intelligence and early warning, responds to and disposes of the assets and continuously monitors the attack surface, and its biggest characteristic is to examine the attack possibilities that can be exploited for all the assets of the enterprise from the perspective of the external attacker, and all the assets here include known assets The most important feature of this approach is that it looks at all the assets of the enterprise from the perspective of an external attacker, and all the assets here include known assets, unknown assets, digital assets, corporate branding, leaked information, and so on.
3. The mainstream attack surface management in the market now is EASM and CAASM two parts. CAASM is responsible for the exposed surface asset management, mainly to allow security practitioners to map the assets, targeted protective measures; EASM for the exposed surface management, aimed at the possible existence of assets on the exposed surface of the investigation and detection, in order to maximise the reduction of security threats.
An attack surface are all points in the system accessible by a potential attacker, including entry points, interfaces, and functions that may be used to compromise security. Attack face analysis aims to provide cheat tables, guidance, and best practices for identifying and evaluating the attack face of Web applications.
This article describes a simple and pragmatic way of doing Attack Surface Analysis and managing an application’s Attack Surface. It is targeted to be used by developers to understand and manage application security risks as they design and change an application, as well as by application security specialists doing a security risk assessment.
Attack Surface Analysis helps you to:
identify what functions and what parts of the system you need to review/test for security vulnerabilities
identify high risk areas of code that require defense-in-depth protection – what parts of the system that you need to defend
identify when you have changed the attack surface and need to do some kind of threat assessment
The Attack Surface of an application is:
the sum of all paths for data/commands into and out of the application, and
the code that protects these paths (including resource connection and authentication, authorization, activity logging, data validation and encoding)
all valuable data used in the application, including secrets and keys, intellectual property, critical business data, personal data and PII, and
the code that protects these data (including encryption and checksums, access auditing, and data integrity and operational security controls).
Group each type of attack point into buckets based on risk (external-facing or internal-facing), purpose, implementation, design and technology. You can then count the number of attack points of each type, then choose some cases for each type, and focus your review/assessment on those cases.
This article delves into the concept of the attack surface and why organizations must pay heed to it. The definition of the attack surface serves as its fundamental aspect. Essentially, the attack surface reveals the potential vulnerabilities that may exist within an application.
To define the attack surface, one must first identify the entry points. These can be APIs, UI form fields, among others. Subsequently, it’s crucial to determine the valuable data points and their locations. This approach sheds light on the critical areas of the application that warrant the utmost protection.
Lastly, testers should dedicate time to attempting to “hack” the application. They should execute key functions such as creating accounts or placing orders. Additionally, maintaining multiple versions or keeping older versions of applications or code for future use can also expand the attack surface. In essence, organizations must be cognizant of their attack surface to ensure the security of their applications and valuable data.
The OWASP Attack Surface Analysis Cheat Sheet is a document published by the OWASP (Open Web Application Security Project) organization. It provides a set of methods and tools to help developers, testers, and security professionals assess and analyze the attack surface of an application, in order to better understand potential security risks.
The attack surface refers to the various avenues and vulnerabilities that an application might be exposed to. By analyzing the attack surface, one can identify the weak points of an application’s security and take appropriate measures to strengthen its defenses.

In practice, security teams and developers can use the OWASP Attack Surface Analysis Cheat Sheet to guide their security analysis and improvement efforts. By regularly assessing and adjusting the attack surface, they can ensure that Web applications maintain a high level of security in the face of ever-changing threats. Provides practical guidance to security teams and developers on how to identify, analyze, and reduce Web application attack surfaces.
Attack Surface Analysis is targeted to be used by developers to understand and manage application security risks as they design and change an application, as well as by application security specialists doing a security risk assessment. Attack Surface Analysis is about mapping out what parts of a system need to be reviewed and tested for security vulnerabilities. The point of Attack Surface Analysis is to understand the risk areas in an application, to make developers and security specialists aware of what parts of the application are open to attack, to find ways of minimizing this, and to notice when and how the Attack Surface changes and what this means from a risk perspective.
Attack Surface Analysis helps you to:
1. identify what functions and what parts of the system you need to review/test for security vulnerabilities
2. identify high risk areas of code that require defense-in-depth protection – what parts of the system that you need to defend
3. identify when you have changed the attack surface and need to do some kind of threat assessment
This chapter details the importance of attack surface analysis and the definition of attack surface analysis.
Attack surface analysis is done to determine which parts of the system need to be examined and tested for security vulnerabilities. The purpose of attack surface analysis is to understand the areas of risk in an application so that developers and security professionals understand which parts of the application are vulnerable to attack, find ways to minimize the attack surface, and note when and how the attack surface changes and what that means from a risk perspective.
Changes to session management, authentication, and password management directly impact the attack surface and need to be reviewed. The same is true for changes to authorization and access control logic, especially adding or changing role definitions, adding administrative users with elevated privileges, or managing functions.
Chun Liu says

Attack Surface Analysis helps you to:
identify what functions and what parts of the system you need to review/test for security vulnerabilities
identify high risk areas of code that require defense-in-depth protection – what parts of the system that you need to defend
identify when you have changed the attack surface and need to do some kind of threat assessment
The Attack Surface of an application is:
the sum of all paths for data/commands into and out of the application, and
the code that protects these paths (including resource connection and authentication, authorization, activity logging, data validation and encoding)
all valuable data used in the application, including secrets and keys, intellectual property, critical business data, personal data and PII, and
the code that protects these data (including encryption and checksums, access auditing, and data integrity and operational security controls).
Group each type of attack point into buckets based on risk (external-facing or internal-facing), purpose, implementation, design and technology. You can then count the number of attack points of each type, then choose some cases for each type, and focus your review/assessment on those cases.

This article delves into the concept of the attack surface and why organizations must pay heed to it. The definition of the attack surface serves as its fundamental aspect. Essentially, the attack surface reveals the potential vulnerabilities that may exist within an application.
To define the attack surface, one must first identify the entry points. These can be APIs, UI form fields, among others. Subsequently, it’s crucial to determine the valuable data points and their locations. This approach sheds light on the critical areas of the application that warrant the utmost protection.
Lastly, testers should dedicate time to attempting to “hack” the application. They should execute key functions such as creating accounts or placing orders. Additionally, maintaining multiple versions or keeping older versions of applications or code for future use can also expand the attack surface. In essence, organizations must be cognizant of their attack surface to ensure the security of their applications and valuable data.

The OWASP Attack Surface Analysis Cheat Sheet is a document published by the OWASP (Open Web Application Security Project) organization. It provides a set of methods and tools to help developers, testers, and security professionals assess and analyze the attack surface of an application, in order to better understand potential security risks.
The attack surface refers to the various avenues and vulnerabilities that an application might be exposed to. By analyzing the attack surface, one can identify the weak points of an application’s security and take appropriate measures to strengthen its defenses.
The OWASP Attack Surface Analysis Cheat Sheet covers a range of considerations, including but not limited to:
1. Application functionality and business processes: Analyzing the functionality and various business processes of the application to identify potential entry points and attack vectors.
2. External dependencies and integrations: Considering the dependencies and integrations of the application with external components, services, and libraries, and analyzing the potential security risks introduced by these dependencies.
3. Configuration and deployment: Assessing the configuration and deployment environment of the application, including servers, network devices, and databases, to identify potential configuration errors and security vulnerabilities.
4. Data handling and storage: Analyzing the application’s data handling processes and storage mechanisms, evaluating the sensitivity of the data and the protection measures in place.
5. Authentication and access control: Analyzing the application’s authentication and access control mechanisms, evaluating potential weaknesses and flaws, such as password policies, session management, and authorization controls.
6. Input validation and filtering: Assessing the application’s input validation and filtering measures, analyzing potential input validation bypass and injection vulnerabilities.
7. Error handling and logging: Analyzing the application’s error handling mechanisms and logging practices, evaluating potential information leaks and the likelihood of exploitation.
8. Key and password management: Evaluating the application’s management of keys and passwords, including encryption algorithms, key storage, and password reset procedures.
The OWASP Attack Surface Analysis Cheat Sheet provides detailed recommendations and guidance to help security professionals systematically assess and analyze the attack surface of an application. By following the steps and utilizing the tools provided in the cheat sheet, potential security risks can be identified and appropriate measures can be taken to protect the application from attacks.

The attack surface refers to all entry points and vulnerabilities in a system or application that could be exploited by a potential attacker. By gaining a deeper understanding of the attack surface, teams can more precisely identify security risks and take protective measures accordingly.
In practice, security teams and developers can use the OWASP Attack Surface Analysis Cheat Sheet to guide their security analysis and improvement efforts. By regularly assessing and adjusting the attack surface, they can ensure that Web applications maintain a high level of security in the face of ever-changing threats. Provides practical guidance to security teams and developers on how to identify, analyze, and reduce Web application attack surfaces.

Attack Surface Analysis is targeted to be used by developers to understand and manage application security risks as they design and change an application, as well as by application security specialists doing a security risk assessment. Attack Surface Analysis is about mapping out what parts of a system need to be reviewed and tested for security vulnerabilities. The point of Attack Surface Analysis is to understand the risk areas in an application, to make developers and security specialists aware of what parts of the application are open to attack, to find ways of minimizing this, and to notice when and how the Attack Surface changes and what this means from a risk perspective.
Attack Surface Analysis helps you to:
1. identify what functions and what parts of the system you need to review/test for security vulnerabilities
2. identify high risk areas of code that require defense-in-depth protection – what parts of the system that you need to defend
3. identify when you have changed the attack surface and need to do some kind of threat assessment

This chapter details the importance of attack surface analysis and the definition of attack surface analysis.
Attack surface analysis is done to determine which parts of the system need to be examined and tested for security vulnerabilities. The purpose of attack surface analysis is to understand the areas of risk in an application so that developers and security professionals understand which parts of the application are vulnerable to attack, find ways to minimize the attack surface, and note when and how the attack surface changes and what that means from a risk perspective.
Changes to session management, authentication, and password management directly impact the attack surface and need to be reviewed. The same is true for changes to authorization and access control logic, especially adding or changing role definitions, adding administrative users with elevated privileges, or managing functions.
