According to the Application Security Risk Report by Micro Focus, over 61% of high-risk vulnerabilities in applications go unnoticed by typical security checklists like the OWASP Top 10. In other words, common security guides may miss more than half of the severe risks facing applications today, leaving them open to attacks.
When even one breach can shake customer confidence and tarnish your brand’s reputation, traditional methods alone won’t cut it. Security testing automation steps up here, catching these hidden vulnerabilities faster and more accurately. Let’s dive into how security testing automation can help safeguard your applications by finding what typical checks overlook.
What is security testing?
Think of security testing as a thorough home security check for your application. You wouldn’t leave your front door unlocked or ignore a broken window; similarly, security testing looks for and fixes any gaps that could open your app to attack. It’s about ensuring your software is ready to handle potential threats before they become real problems.
In practice, security testing ensures that your app meets key standards, assesses protective features, and simulates attacks to uncover weaknesses. It flags vulnerabilities and offers recommendations for improvement. The ultimate goal? To lower security risks and make your software as resilient as possible.
Types of security testing to know
Each security testing type targets a unique purpose, from automated scans that highlight known risks to penetration testing that mimics real-world attacks:
- Vulnerability scanning: Automated tools scan for known vulnerabilities and potential risks.
- Penetration testing: Simulated attacks are run to find exploitable security gaps.
- Application security testing: Involves detailed analysis of the application to uncover risks and improve security.
- Web application security testing: Focuses on web-specific vulnerabilities like SQL injections and cross-site scripting.
- API testing: Checks the security of APIs, guarding against denial-of-service attacks and more.
- Security auditing: A thorough examination that reviews code, conducts scans, and verifies best practices.
- Risk assessment: Evaluates and prioritizes potential threats based on their impact.
- Security posture assessments: Looks at an organization’s overall security strategy, policies, and tools.
Why should you automate security testing?
Security testing automation is more than just a safeguard for sensitive data – it’s a foundational part of building a secure, reliable application that users and clients can trust. Automated security testing works as a vigilant “digital watchdog,” continuously scanning for vulnerabilities and ensuring that security is embedded into every part of your development process. Here’s how it makes a difference:
- Data protection and breach prevention: Automated testing protects sensitive information by identifying vulnerabilities before they become costly data breaches, preventing unauthorized access to your system.
- Trust building: A secure, automated system builds confidence among clients and users, showing that their information is protected.
- Compliance assurance: For industries with strict security standards, automated testing helps maintain compliance with regulatory requirements.
- System reliability and streamlined development: By integrating security testing into your workflow, you can maintain consistent security checks without slowing down development, ensuring your application remains stable and secure as it evolves.
- Reduces manual effort and human error: Automating repetitive checks minimizes oversight and maintains consistency in security scans.
- Enables early intervention and quick feedback: Automated tests offer immediate alerts on vulnerabilities, allowing developers to address issues promptly and keep the development process efficient and secure.
Common challenges and solutions in security testing automation
Implementing security testing automation can come with its own set of challenges. However, with the right strategies, you can overcome them:
- Tool selection: Not all tools are equally effective across different application types. To address this, research tools that align with your specific needs, whether for web, mobile, or API testing.
- Team training: New tools and methods make team training essential. Regular training sessions ensure that everyone on your team stays updated on the latest security techniques and tools.
Facing these challenges head-on with clear solutions ensures your security testing automation strategy is both robust and adaptable.
Key tools in security testing automation
Choosing the right tools is essential for effective security testing automation. Here’s a brief overview of some popular tools and their main benefits:
- SAST (Static Application Security Testing): Ideal for early detection, focusing on code-level vulnerabilities before runtime.
- DAST (Dynamic Application Security Testing): Best for runtime issues, simulating attacks as the application runs to detect vulnerabilities.
- IAST (Interactive Application Security Testing): Combines SAST and DAST for real-time analysis, providing continuous insights as the app runs.
These tools help identify security issues from different perspectives, providing well-rounded coverage for your application.
Metrics to track for measuring security testing automation success
Tracking metrics is key to gauging the effectiveness of your security testing automation strategy. Here are a few essential metrics to monitor:
- Number of vulnerabilities detected: Track how many are caught over time to gauge the testing’s effectiveness.
- Time to remediation: Measure how quickly vulnerabilities are resolved to assess efficiency.
- Reduction in security incidents: Observing a drop in incidents can indicate successful testing outcomes and overall security improvement.
Focusing on these metrics will give you a clear view of the impact of your security testing automation efforts and allow you to adjust strategies as needed.
How to perform security testing automation
With increasing cyber threats, security testing automation is crucial to protect your applications from vulnerabilities.
1. Planning: Setting objectives and scope
Start by planning out your security goals. Think of this phase as identifying which doors and windows a burglar might try to get through. Testers define specific security objectives, focusing on critical areas like data protection, authentication, and network security. This planning phase also typically includes a risk assessment to prioritize testing efforts.
2. Designing test cases and scenarios
Once objectives are set, testers design scenarios to reflect real-world threats. If your planning phase pointed out that SQL injection could be a risk, testers will create test cases that mimic these malicious attempts. Think of it as inviting a “friendly hacker” to test your defenses. This helps ensure your app has no cracks in its armor and that your tests cover a wide range of scenarios.
3. Execution: Conducting automated security tests
This is the moment of truth – executing your security testing automation to see where weaknesses lie. Here’s what this involves:
- Penetration testing: Simulates real attacks to uncover exploitable security gaps.
- Vulnerability scanning: Automated tools scan for known vulnerabilities like outdated libraries or missing security headers, which hackers often exploit.
- Code review: Goes through the code to identify issues, like hardcoded passwords or insecure data handling methods.
Execution is often iterative, meaning testers may go back and retest once vulnerabilities are fixed to ensure new issues haven’t been introduced.
4. Reporting: Documenting findings
After tests run, it’s time to document all findings in a report that helps developers know what to prioritize. List each vulnerability, its severity, and potential impact.
5. Review and retest
In the final phase, testers review and retest fixes to ensure everything holds up. For example, if session management issues were flagged, the retest would involve logging in and out multiple times to verify that an attacker cannot reuse expired sessions. This cycle repeats until the application meets security standards.
Best practices for automated security testing
- Start early and test continuously: Implement security testing from the start and integrate it throughout development. Catching issues early simplifies resolution and minimizes costs.
- Combine automated and manual testing: While automation speeds up common security checks, manual testing provides insights that automated tools may miss, like complex logical flaws.
- Stay updated on emerging threats: Cyber threats evolve rapidly. To adapt your testing strategies accordingly, keep up with the latest vulnerabilities and threats.
- Diversify testing methods: Use a mix of SAST, DAST, and penetration testing for well-rounded coverage, targeting code, runtime behavior, and access control vulnerabilities.
- Update security tools regularly: Ensure your tools are up-to-date to catch new types of vulnerabilities. Outdated tools can leave security gaps.
- Educate the team: Continuous security training helps the development team write safer code and identify risks early on, creating a proactive security culture.
How manual testing complements security testing automation
While automated security testing keeps the application under constant surveillance, manual testing – specifically functional and exploratory testing – adds an essential layer of insight that automation alone can’t provide. Here’s how these hands-on approaches work together to create a well-rounded security strategy.
1. Functional testing: Verifying security features and user workflows
Functional testing focuses on ensuring each security feature in your application works how it’s supposed to within real user flows. Here’s how it adds value:
- Double-checking login and access controls: Automation can test if the login page exists and functions, but manual testing goes deeper. Testers can check that permissions are correctly set up across different user roles and that restricted areas are genuinely locked down for unauthorized users.
- Spotting access control gaps: Functional testing helps ensure users only see what they’re allowed to see, especially when navigating complex user workflows.
- Reviewing error messages and responses: While automation may detect the presence of error messages, manual testing ensures that these messages don’t reveal too much information, like database details or internal API responses, that could be useful to potential attackers.
Functional testing complements automation and verifies that security features work as intended in real-world conditions, catching flaws that could slip through if only automated checks were used.
2. Exploratory Testing: Finding unpredictable vulnerabilities
Exploratory testing takes a creative, open-ended approach to uncovering security issues that automation might miss. Here’s why it’s so valuable:
- Understanding real-user behavior: Exploratory testers play the role of real users, clicking around in unexpected ways to reveal areas that may lack security or expose sensitive data unintentionally.
- Exploring edge cases and unusual scenarios: Exploratory testers often try out unusual user inputs or paths, which automated scripts may not anticipate. For instance, they might enter special characters or try to navigate around access controls creatively.
- Simulating real-world attacks: Exploratory testing allows testers to replicate unconventional attack strategies, uncovering flaws like business logic errors or session management issues that automation alone may not detect.
Exploratory testing offers flexibility and human intuition, which can reveal issues automation might overlook – especially those that require adaptive thinking to uncover.
The power of combining manual and automated testing
Together, manual and automated testing provide a solid, well-rounded approach:
- Fuller coverage: Automation handles the high-volume, repetitive checks, catching predictable vulnerabilities, while manual testing dives deeper into complex workflows and edge cases that only human testers might think to explore.
- Catching complex logic flaws early: Exploratory and functional testing reveal issues within business logic and dependencies between workflows that often go unnoticed by automated
tests. - Complete security: Automated testing keeps security checks running in the background, providing consistency, while manual testing adds depth by validating controls from a real user’s perspective and catching vulnerabilities that only emerge through creative testing.
