Application security testing (AST) involves leveraging various testing techniques to improve the quality and security of software applications by identifying, remediating, and ultimately preventing weaknesses and vulnerabilities in all phases of the software development process.
This is a proven way to help prevent cyberattacks. Application security attacks are the most common form of external attack. That’s why improving application security is one of the leading priorities and concerns for security decision makers.
The process of identifying and remediating application vulnerabilities works best when it’s closer to the developer and can be integrated as a part of functional testing. Parasoft AST tools extend automated application security testing across the SDLC to help uncover security and quality issues that could expose security risks in your software applications. This increases collaboration in DevSecOps and provides an effective way for you to identify and manage security risks more confidently.
This includes static application security testing, penetration testing, using various testing tools, and more. Let’s learn more about the kinds of security vulnerabilities this strategy can mitigate and the tools to improve strategies further. This page also covers SAST, DAST, and IAST.
The benefits of AST are realized when testing is done early and often to provide visibility into application security risks. Modern software development demands for automation to deliver software applications at speed, without sacrificing security and quality.
Seamlessly integrate security into developers’ daily activities and development pipelines to address security issues in real time.
Finding issues early allows for:
Extending application security testing into your CI/CD pipeline and tool chains ensures continuous testing to expose risk in your software applications as code changes are being made.
Automating these strategies enables:
The “do it early and do it often” strategy provides assurances that software applications are free from known application vulnerabilities to help development teams deliver and deploy software with confidence.
Assured software security at speed provides:
Static Application Security Testing (SAST)
SAST leverages static analysis techniques to analyze source code, byte code, and binaries for coding violations and software weaknesses that expose vulnerabilities in software.
SAST tools provide awareness and feedback to developers about the impact of their coding and refactoring activities in creating vulnerabilities in software.
Dynamic Application Security Testing (DAST)
In contrast, DAST uses black box testing where code is executed then inspected for vulnerabilities.
These tools can often perform more large-scale reviews by simulating ill-natured test cases and unexpected incidents.
Interactive Application Security Testing (IAST)
IAST combines both DAST and SAST tools in order to provide a more comprehensive list of security weaknesses. These tools dynamically review software while in runtime but operate on an application server. This lets them review compiled code.
IAST tools are great for API testing, as well as reviewing third-party components and data flow.
API Security Testing
Uncovering misuse and abuse of API functionality is essential for API security testing. It encompasses the use of DAST and penetration testing activities to find security threats that expose sensitive data embedded in APIs.
Finding poorly designed and leaky APIs is important to protect your business, mission, and clients.
Introducing automation into your development workflow is a natural fit with the “shift left” strategy. It also empowers your development team by improving efficiency, productivity, and reducing errors. Get started with a Parasoft demo to see how CI/CD pipeline automation might work for your team or how a DevSecOps approach and continuous testing can mitigate security issues.
Chances are that there’s a solution for your problem waiting to be discovered.
“Shift left” means to incorporate early security checks in the SDLC to garner collaboration across development teams, remain agile, and increase developer autonomy, as well as security team oversight. It also reinforces the need to think about security in all phases of the SDLC — from concept through delivery.
In concise terms, DAST offers a runtime analysis of an application from an external perspective. SAST reviews the internal or static aspects of an application. This makes SAST return more issues but is subject to false positives.
Teams should introduce DAST in the Production and QA stages while using SAST in the QA and Development stages of the SDLC.
