With cyber threats constantly evolving security testing is truly a necessity. As technology advances, so do the tactics of hackers looking to exploit vulnerabilities. This rising concern is reflected in the security testing market, valued at $15.4 million in 2024 and expected to grow at 15.2% annually, reaching $62.6 million by 2034.
Why is Security Testing Important in Software QA
Security testing helps ensure that user data remains protected and that software is resilient against cyber threats. Below are four essential reasons you simply cannot skip it:
- Regulatory compliance. Many industries must adhere to strict security standards. Security testing helps maintain compliance, avoiding penalties and reputational damage.
- Data protection. Identifying and fixing vulnerabilities prevents data breaches and unauthorized access to sensitive information.
- System reliability. Security flaws can lead to system crashes or failures. Testing helps uncover weaknesses and improve overall stability.
- User trust. A secure product builds confidence among users, fostering long-term trust and loyalty.
Types of Security Testing
Prioritizing security testing ensures delivering a reliable, trustworthy experience for your users. Here’s a quick rundown of the types of security testing you can use in your QA strategy:
- Penetration testing. Simulates real-world attacks to uncover vulnerabilities, using both manual and automated techniques.
- Vulnerability scanning. Uses automation tools to detect security weaknesses in a product or network infrastructure.
- Application security testing (AST). Evaluates web applications and services for vulnerabilities, addressing both external and internal threats.
- Web application security testing. A subset of AST that targets web-based applications, identifying issues like SQL injection and authentication flaws.
- API security testing. Assesses API security by sending malicious requests to detect weaknesses and ensure data protection.
- Risk assessments. Identifies and prioritizes security threats to develop effective risk mitigation strategies.
When Should Security Testing Start in the SDLC?
Security testing should be integrated throughout the software development lifecycle (SDLC)—a practice known as shift-left security to catch vulnerabilities early. Here’s a quick breakdown:
- Requirement analysis stage. Define security needs based on compliance and application purpose.
- Design stage. Conduct threat modeling and architectural risk analysis.
- Development stage. Implement secure coding practices and use SAST to detect vulnerabilities.
- Testing stage. Run DAST and penetration tests to uncover runtime security flaws.
- Deployment stage. Perform a final security assessment before release.
- Maintenance stage. Continuously scan, monitor, and patch vulnerabilities.
Security Testing Techniques
When it comes to security testing, a one-size-fits-all approach doesn’t cut it. To safeguard applications against vulnerabilities, teams rely on four primary techniques:
- SAST (Static Application Security Testing) – Scans source code, bytecode, or binaries in a non-executing state to identify vulnerabilities early in development. Think of it as a preemptive strike against security flaws. Popular SAST tools include: Aikido, Cycode SAST, and Checkmarx SAST.
- DAST (Dynamic Application Security Testing) – Examines the app while it’s running to uncover runtime vulnerabilities like authentication issues or data leaks. Ideal for assessing security from an attacker's perspective. Popular DAST tools include: OWASP Zap, JIT, and Veracode.
- IAST (Interactive Application Security Testing) – A hybrid approach combining SAST and DAST. It provides real-time insights into vulnerabilities while the application is running, making it easier to pinpoint security risks. Popular IAST tools include: Invincti and Acutenix.
- MAST (Mobile Application Security Testing) – Tailored specifically for mobile apps, MAST focuses on identifying platform-specific threats and providing remediation guidance. Popular MAST tools include: AppKnox Mobile Application Security, Checkmarx for Mobile AST.?
Final Thoughts
Security testing isn’t optional—it’s essential. As applications grow in complexity, so do the risks. Threats like insecure data storage, authentication flaws, and supply chain vulnerabilities can compromise sensitive information and erode user trust.
A proactive approach to security testing ensures stronger applications, safer user data, and a more efficient development process. By leveraging advanced tools and testing strategies, businesses can detect and fix vulnerabilities before they become costly issues.
