Overcoming Challenges in Static Application Security Testing

 

In today's fast-paced digital world, it's crucial for businesses to keep their applications secure from cyber threats. One way to ensure the security of applications is through static application security testing (SAST). SAST is a type of testing that helps detect vulnerabilities in the source code of an application. However, like any other testing methodology, SAST also comes with its own set of challenges. In this blog post, we will discuss some of the common challenges in static application security testing and how to overcome them.

 

Common Challenges in Static Application Security Testing

·      False Positives

One of the biggest challenges of SAST is the high number of false positives. False positives occur when the tool reports a vulnerability that doesn't actually exist. False positives can waste valuable time and resources in fixing vulnerabilities that don't exist, and can also distract developers from actual vulnerabilities.

·      Integration with Development Process

Integrating SAST into the development process can be challenging, especially if it's done after the application is already built. Static Application Security Testing should be incorporated early in the development cycle so that developers can identify vulnerabilities and fix them as soon as possible.

·      Lack of Expertise

Static Application Security Testing requires a certain level of expertise to use the tool effectively. Developers need to be trained to understand the output of the tool, and how to fix the vulnerabilities detected.

·      Code Coverage

SAST can only identify vulnerabilities in the code that has been scanned. If the tool doesn't scan all of the code, it could miss potential vulnerabilities.

·      Cost

Static Application Security Testing tools can be expensive, especially for small businesses. The cost of implementing SAST needs to be weighed against the benefits of having secure applications.

 

How to Overcome these Challenges

·      Reduce False Positives

To reduce false positives, it's important to tune the SAST tool. Tuning involves configuring the tool to filter out false positives and report only actual vulnerabilities. This can be done by adjusting the rules and thresholds of the tool.

·      Incorporate SAST Early in the Development Cycle

To integrate Static Application Security Testing into the development process, it's important to involve developers from the beginning. Developers should be trained to understand the tool and its output, and how to fix vulnerabilities. SAST should also be integrated into the build process so that vulnerabilities can be detected and fixed automatically.

·      Training and Education

To overcome the lack of expertise, developers should be trained in SAST. This includes understanding the output of the tool and how to fix vulnerabilities. Developers should also be educated on secure coding practices to reduce the likelihood of introducing vulnerabilities.

·      Increase Code Coverage

To increase code coverage, it's important to use a tool that can scan all of the code. Developers should also ensure that all code is scanned before it's deployed.

·      Cost-Effective SAST

To make Static Application Security Testing cost-effective, businesses should choose an SAST tool that suits their budget and needs. Businesses can also consider open-source SAST tools, which are often free or low-cost.

 

Conclusion

Static Application Security Testing (SAST) is a crucial methodology for ensuring the security of software applications. However, it comes with its own set of challenges. By reducing false positives, incorporating SAST early in the development cycle, providing training and education and increasing code coverage, businesses can overcome these challenges and ensure that their applications are secure. While cost can be a barrier to implementing SAST, there are cost-effective options available such as open-source SAST tools and cloud-based SAST services.

Overall, implementing Static Application Security Testing requires a commitment to ongoing training and education, and a willingness to integrate it into the development process. By doing so, businesses can ensure that their applications are secure and protect their customers' data and sensitive information.
