Static application security testing
Static application security testing (SAST) is used to secure software by reviewing its source code to identify security vulnerabilities. Although the process of checking programs by reading their code (modernly known as static program analysis) has existed as long as computers have existed, the technique spread to security in the late 90s and the first public discussion of SQL injection in 1998 when web applications integrated new technologies like JavaScript and Flash.
Unlike dynamic application security testing (DAST) tools for black-box testing of application functionality, SAST tools focus on the code content of the application, white-box testing. A SAST tool scans the source code of applications and their components to identify potential security vulnerabilities in their software and architecture. Static analysis tools can detect an estimated 50% of existing security vulnerabilities in tested applications.
In the software development life cycle (SDLC), SAST is performed early in the development process and at code level, and also when all pieces of code and components are put together in a consistent testing environment. SAST is also used for software quality assurance, even if the many resulting false positives impede its adoption by developers.
SAST tools are integrated into the development process to help development teams as they are primarily focusing on developing and delivering software respecting requested specifications. SAST tools, like other security tools, focus on reducing the risk of downtime of applications or that private information stored in applications is not compromised.
Application security tests conducted before their release include static application security testing (SAST), dynamic application security testing (DAST), and interactive application security testing (IAST), which is a combination of the two.
Static analysis tools examine the text of a program syntactically. They look for a fixed set of patterns or rules in the source code. Theoretically, they can also examine a compiled form of the software. This technique relies on instrumentation of the code to do the mapping between compiled components and source code components to identify issues. Static analysis can be done manually as a code review or auditing of the code for different purposes, including security, but it is time-consuming.
The precision of SAST tools is determined by their scope of analysis and the specific techniques used to identify vulnerabilities. Different levels of analysis include the following:
The scope of the analysis determines its accuracy and capacity to detect vulnerabilities using contextual information. SAST tools, unlike DAST tools, give developers real-time feedback, and help them secure flaws before they move the code to the next level.
