Top 13 SAST Tools: Static Application Security Testing

Static Application Security Testing (SAST) is a type of security testing that is performed on an application’s source code or binaries without actually executing the code. It is a proactive security measure that aims to identify vulnerabilities and weaknesses in the code early in the development lifecycle, before the application is deployed.

SAST analyzes the entire codebase to identify potential vulnerabilities, such as buffer overflows, SQL injections, cross-site scripting (XSS), and insecure coding practices. This is done by using static code analysis techniques, including pattern matching, data flow analysis, control flow analysis, and taint analysis.

Pattern matching involves searching for known insecure coding patterns, such as hard-coded credentials or insecure cryptographic algorithms. Data flow analysis tracks how data flows through the application and identifies potential sources of untrusted data that can be exploited. Control flow analysis examines the sequence of instructions in the code to detect any potential vulnerabilities in the logic. Taint analysis identifies how user inputs are used in the application and checks if they are appropriately validated and sanitized before being used to prevent security vulnerabilities.

SAST tools are used to automate the process of analyzing the source code or binaries. These tools parse the code and perform the various analysis techniques to identify potential vulnerabilities. They generate reports that highlight the vulnerabilities found and provide recommendations for remediation.

One of the main advantages of SAST is that it can be performed early in the development process when the cost of fixing vulnerabilities is relatively low. By identifying vulnerabilities at this stage, developers can implement security controls and best practices to mitigate those risks before they become more complex and costly to fix.

SAST also helps to uncover vulnerabilities that are difficult to identify through other testing methods, such as dynamic testing. Dynamic testing involves executing the application and observing its behavior to detect vulnerabilities, whereas SAST can analyze the entire codebase and uncover vulnerabilities that may be hidden or difficult to observe during runtime.

Another advantage of SAST is that it can be used to ensure compliance with security standards and best practices. SAST tools can be configured to check if the code adheres to coding guidelines, security coding standards, and industry best practices. This ensures that developers are following secure coding practices and reduces the likelihood of introducing vulnerabilities into the application.

However, there are also some limitations to SAST. It may generate false positives or false negatives, meaning it may flag code as vulnerable when it is not or miss vulnerabilities that are present. False positives can be time-consuming to investigate and can lead to a loss of trust in the SAST tool. False negatives can give developers a false sense of security, leading to the deployment of a vulnerable application.

Furthermore, SAST tools may not be able to identify vulnerabilities that are introduced at runtime or through complex interactions between different components of the application. Therefore, SAST should be used in conjunction with other security testing methods, such as dynamic testing and penetration testing, to achieve a comprehensive security assessment of the application.

Static application security testing is a valuable security testing technique that helps identify potential vulnerabilities and weaknesses in an application’s source code or binaries. By analyzing the code early in the development process, organizations can proactively address security issues and reduce the risk of deploying vulnerable applications. However, SAST should be used in conjunction with other testing methods to ensure comprehensive security testing.
