Static Application Security Testing (SAST) – Everything One Needs to Know

  • SAST:


One of the most well-established approaches for application security testing is static application security testing (SAST). The SAST is a kind of white-box testing in which source code is assessed inside out while components rest, and the results are reported back to the tester. “A set of tools for analyzing application source code, byte code, and binaries for coding and design situations indicative of security vulnerabilities,” according to Gartner, is what SAST is.


  • What Is the Function of SAST?


SAST, as the name implies, examines and tests static code while the application is not running. SAST is often used throughout the development process, including the coding and testing stages, and is widely used in conjunction with continuous integration servers and, more recently, integrated development environments. A code and design scan is performed in-house by SAST to uncover problems that may indicate weaknesses that might lead to security vulnerabilities.

SAST scans are performed by a predetermined set of criteria that specify the source code defects that must be handled and assessed by the SAST scanner. SAST scans may be customized to identify the most common security issues, such as SQL injection, input validation, stack buffer overflows, and other vulnerabilities.


  • How to Select the Most Appropriate SAST Tool for one’s Organization


The AST market is densely packed with SAST services, which are sometimes packaged with other solutions, making it challenging to discover the best match for their firm.


The criteria from OWASP can assist businesses in narrowing down their choices and picking the solution that will most effectively help them enhance their application security strategies:

Language support is a critical concern. However, ascertain that the SAST tool they employ provides comprehensive coverage for those languages.


  • Compensating for vulnerabilities:


Inspect to ensure that their SAST tool solves at least the Top Ten web application security vulnerabilities defined by the Open Web Application Security Project (OWASP).


  • Accuracy:


SAST accuracy is a weakness, and there will always be false positives and negatives; therefore, verifying the accuracy of any SAST instruments their company is considering is essential.


  • Compatibility:


As with any automated technology, the SAST tool they choose must be compatible with the frameworks they are presently using to enable smooth integration into their SDLC process.

  • Integration with the integrated development environment (IDE):

A SAST tool that is integrated into their IDE can save them both time and money in the long run when dealing with remediation.

  • Simple integration:


Choose a simple SAST tool to configure and connect with the other tools in their DevOps pipeline as effortlessly as feasible.


  • Scalability:


Ascertain that the SAST tool they incorporate today can grow to serve more developers and projects in the future. Although a SAST tool may seem to scan swiftly on a small sample project, ensure that it performs similarly on more significant projects.


The increased scale may also affect the cost of the solution. According to OWASP’s list, it is critical to assess if the cost changes by user, company, application, or line of code analyzed.

What are the primary benefits of SAST?


The following are the primary advantages of SAST:


  • Security Shift Left


SAST enables the early phases of the software development lifecycle to include security. This allows security testers to identify vulnerabilities in proprietary code during the design or coding phases when they are relatively straightforward to remedy.


If security procedures are left to the end, they risk introducing security vulnerabilities into the production environment. Shifting security to the left helps lower both the risk and expense of addressing security problems.


SAST can assist in evaluating vulnerabilities on both the client-side and the server-side. Application security testing identifies vulnerabilities in the source code or binaries, such as SQL injection, cross-site scripting, and buffer overflows.

Real-time security testing enables vulnerabilities to be addressed before the SDLC progresses further, preventing security concerns from escalating into significant hazards for their end-users and the company.


  • Ascertain Secure Coding:


Secure coding is critical for every kind of software, regardless of whether it runs on websites, PCs, mobile devices, or embedded systems. Software written in an insecure manner is an easy target for attackers and may be exploited to do destructive actions.


This might result in a denial of service attack, data loss, sensitive data leakage, damage to end-user software and systems, and even a negative influence on their organization’s brand reputation, resulting in further losses.

SAST contributes to the software’s strength and security by ensuring that the code is solid and secure. In addition, it enables developers to validate that their code complies with certain coding standards (such as CERT) and guidelines prior to releasing it to the production environment.

Scrum masters and product owners often use SAST technologies to enforce safe code standards throughout their development teams and businesses. This enables a more rapid reduction of vulnerabilities and an enhancement in the integrity of the code.


  • Effortless and Accurate:


SAST tools can comprehensively scan their code and do so significantly more quickly than people doing manual secure code checks. We employ SAST techniques to browse millions of lines of code to find and remediate security flaws automatically.

At Cypress Data Defense, our security professionals guarantee that security is built into every line of code, from design to final production. In addition, we are all aware of how frequently developers release new upgrades and products, which implies that security must keep up.


We have a variety of automated SAST solutions that we have been using for years and have shown to be quite effective and efficient. These automatic tools monitor the code on a regular basis, removing the need for them to review the code continually.


Once the automated testing results are available, they may gather insights, generate usage statistics, and rapidly track and repair problems. In a word, SAST tools assist developers in reducing the time required to debug their source code.
