Static Application Security Testing (SAST) is often used to scan the source, binary, or byte code of an application. As well as identifying the root cause of vulnerabilities, it helps to remediate any underlying security flaws and provides feedback to developers on any coding problems. The major benefit is to have more code created with fewer vulnerabilities.

What Is Static Application Security Testing?

SAST is a mature application security testing method, where source code is analyzed from the inside out while components are at rest. It scans in-house code and design to detect flaws that are indicative of weaknesses that could lead to security vulnerabilities.

SAST doesn’t scan dynamic code. It focuses on static code and tests code at rest, without having to run it. That makes it easy to use at the coding and testing stages of development, integrating into Continuous Integration (CI) servers and, more recently, into integrated development environments (IDEs).

The scans done by SAST tools are based on predetermined rules that define coding errors to assess and address. These scans are very good at identifying common security vulnerabilities such as SQL injection, input validation, and stack buffer overflows.

SAST has limitations, however. It is good at finding problems within the code, but not vulnerabilities outside the code in areas such as APIs. That requires a different approach known as Dynamic Application Security Testing (DAST). There are also other related tools known as Mobile Application Security Testing (MAST), and Interactive Application Security Testing (IAST).

What Is the Difference Between SAST and DAST?

SAST methods are generally used early in the development cycle to test the application from the inside out (also known as white box testing). No need to have perform the code analysis on a running system; these tools test line-by-line.

DAST, on the other hand, is a black box testing approach that is done while the application is running, taking an outside-in approach. DAST makes attempts to penetrate the application to identify vulnerabilities. Its testing encompasses bugs outside the code and in third-party interfaces, source code, byte code, and binaries — which usually makes such analysis easier to use and less expensive than SAST.

However, DAST tools may not be able to isolate the exact site of a weakness in the code. Thus, it is probably best to adopt a hybrid analysis testing method that combines both SAST and DAST.
