![]() ![]() 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 paths (including resource connection and authentication, authorization, activity logging, data validation and encoding).the sum of all paths for data/commands into and out of the application, and.The Attack Surface describes all of the different points where an attacker could get into a system, and where they could get data out. identify when you have changed the attack surface and need to do some kind of threat assessmentĭefining the Attack Surface of an Application ¶.identify high risk areas of code that require defense-in-depth protection - what parts of the system that you need to defend.identify what functions and what parts of the system you need to review/test for security vulnerabilities.But developers should understand and monitor the Attack Surface as they design and build and change a system. 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.Īttack Surface Analysis is usually done by security architects and pen testers. The internal attack surface is likely to be different to the external attack surface and some users may have a lot of access.Īttack Surface Analysis is about mapping out what parts of a system need to be reviewed and tested for security vulnerabilities. malware injection, social engineering attacks), and there is less focus on insider threats, although the principles remain the same. The focus here is on protecting an application from external attack - it does not take into account attacks on the users or operators of the system (e.g. ![]() 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. This article describes a simple and pragmatic way of doing Attack Surface Analysis and managing an application's Attack Surface.
