Cyber security is a paradigm that every modern organization must embrace. At the moment when cyber threats can no longer be taken for granted; here is when the software applications have to be absolutely secured from possible vulnerability exploitation. This is where application security testing software would come in. Choosing the right devices, however, requires an understanding of the basics of dynamic and static analysis-the two major approaches taken by application security testing tools. Let’s dive into what each of these really is, what are their features, advantages, and when they are applied.
What is Static Application Security Testing (SAST)?
Static Application Security Testing (SAST) is known as a static or white-box testing type of application test which uses source code, bytecode, or binaries to determine security flaws. During application development there is no execution of the application by SAST tools.
Key Features of SAST:
1. Early Detection of Vulnerabilities
SAST is the earlier discovery of security issues for developers regarding their software codes at their early software lifecycle development (SDLC) phases.
2. Entire Code Analysis
It analyzes the whole application code to see if there are any found vulnerabilities such as SQL injection, buffer overflow, insecure API call, etc.
3. Development Tool Integration
Modern SAST goes beyond being just an application security-specific testing model as it now integrates most of the IDEs, CI/CD pipelines, and repositories.
4. In-depth Reporting
SAST produces reports showing where a vulnerability is found and what kind of vulnerability it is so that remediation can happen immediately.
Where to implement SAST
• in the developing stage of proactive security,
• devices with total source code,
• standards compliance for secure coding, like OWASP and PCI-DSS.
Dynamic Application Security Testing (DAST)-what on earth is it?
Dynamic Application Security Testing (DAST). A black box testing approach-tries to test an application to check for vulnerabilities while it is running. It is quite the opposite of SAST. It is not concerned with source code but rather on the behavior of the application at runtime.
DAST Feature Highlights:
1. Runtime vulnerability detection
DAST adopts an external attack simulation method in determining a class of security risks such as cross site scripting (XSS), broken authentication, and misconfigured web applications.
2. Platform Independent
It is platform independent and does not call for source code access; thus, it suits applications that are dependent on third parties and can also accommodate legacy applications.
3. Real-life Simulation
DAST is exactly a real-world simulation as it assesses what action the application would take should it come under threat in a real production-like environment.
4. Scalable
DAST can easily be scaled to assert that a test is run for web applications, APIs, and microservices.
When DAST is to Be Applied
• During testing and deployment of information and technology during SDLC.
• Assess applications that do not provide source code.
• For verifying the strength of security controls in live environments.
Select Appropriate Application Security Testing Software
The choice would depend upon the requirements of your organization. Consider the following aspects:
1. Development Phase
If it is in the early stages of development, you should favor SAST so that it tries to repair things that are going to cost more later.
2. Run-time Validation
DAST is the appropriate choice for runtime analysis or testing after deployment.
3. Corporate Compliance and Risk Mitigation
Perform both: Organizations that really intend to address risk and compliance as a whole must implement both. Best application security tools incorporate platforms that combine SAST and DAST, thus allowing pooled application security management.
4. Ease of Integration
Your testing software must be made totally compatible with the DevSecOps workflow that you have going on.
