Introduction: Why Application Security Testing Matters
If you build software, security for software development isn’t just an add-on—it’s a must. As cyber threats evolve daily, application security testing plays a crucial role in catching vulnerabilities early, making sure safer software development. However, detecting issues is only half the battle. Lebih penting, how do you fix them? To answer this, we will explore different types of application security testing, best practices in security testing in software development, and strategi remediasi that will help you ship secure code efficiently.
Types of Application Security Testing
Security for software development requires more than just a single testing approach. Securing applications isn’t a one-size-fits-all process. Instead, various application security testing methods help uncover vulnerabilities at different stages of the software development lifecycle (SDLC).
By layering these security approaches, teams can strengthen applications, reduce security risks, and prevent vulnerabilities before attackers exploit them. Each method plays a unique role in securing software, ensuring protection from code development to deployment.
Let’s take a closer look at the most effective types of application security testing and how they help teams build safer software.
1. Analisis Komposisi Perangkat Lunak (SCA)
In addition to analyzing proprietary code, modern applications rely heavily on open-source libraries. While these components can be beneficial, they may introduce security risks. That’s where Analisis Komposisi Perangkat Lunak comes in—it helps teams continuously monitor third-party dependencies for vulnerabilities and licensing issues.
Kapan Harus Digunakan: Continuously, across the SDLC.
Cara Bekerja: Scans open-source dependencies for known vulnerabilities and outdated components.
Terbaik Untuk: Preventing supply chain attacks and ensuring compliance with security standards.
2. Pengujian Keamanan Aplikasi Statis (SAST)
First and foremost, catching security flaws early in development is critical. SAST allows developers to identify vulnerabilities before the code is even executed, making sure that issues are resolved before they become costly problems.
Kapan Harus Digunakan: Early in development (shift-left security).
Cara Bekerja: Scans code before execution, detecting vulnerabilities in source, bytecode, or binaries.
Terbaik Untuk: Identifying code-level flaws before deployment.
3. Infrastruktur sebagai Kode (IaC) Security Testing
With the rapid adoption of cloud environments, securing infrastructure configurations is just as important as securing application code. IaC security testing ensures misconfigurations are detected and corrected before deployment.
Kapan Harus Digunakan: Before deploying cloud environments.
Cara Bekerja: Scans Terraform, Formasi Awan, Kubernetes, dan Buruh pelabuhan files for security risks.
Terbaik Untuk: Ensuring secure cloud-native applications and DevOps pipelines.
4. Dynamic Application Security Testing (DAST)
Berbeda SAST, which analyzes static code, DAST takes a different approach by testing applications while they run. By simulating real-world attacks, TERAKHIR identifies security gaps that only appear during execution.
Kapan Harus Digunakan: After deployment, during runtime.
Cara Bekerja: Attacks the app like a hacker would, detecting security weaknesses in a live environment.
Terbaik Untuk: Finding injection attacks, authentication flaws, and misconfigurations.
5. Interactive Application Security Testing (IAST)
Some vulnerabilities can slip through both static and dynamic testing. To bridge the gap, IAST provides real-time security analysis during application execution, allowing teams to detect vulnerabilities dynamically while preserving code context.
Kapan Harus Digunakan: During functional testing.
Cara Bekerja: Uses real-time analysis inside the application to identify security risks.
Terbaik Untuk: Microservices, containerized apps, and cloud-native applications.
6. API Security Testing
As APIs become the backbone of modern applications, they are increasingly targeted by cyberattacks. API security testing ensures that endpoints remain protected from misconfigurations and no authorized access.
Kapan Harus Digunakan: Throughout API development.
Cara Bekerja: Scans for weak authentication, improper configurations, and data exposure.
Terbaik Untuk: Preventing API-related security threats and data leaks.
Best Practices in Security Testing for Software Development
Securing applications isn’t just about running tests—it’s about making security a natural part of the development process. By following these best practices, teams can catch vulnerabilities early, automate security checks, and focus on fixing real threats without slowing down development.
1. Geser Keamanan ke Kiri
Security should start early in the development lifecycle, not after deployment.
- Run SAST ke SCA scan as soon as code is written to prevent security issues from reaching production.
- Give developers umpan balik yang dapat ditindaklanjuti so they can fix vulnerabilities before they become major risks.
2. Automate Security in CI/CD Pipelines
Security should work at DevOps speed, not slow it down.
- Mengintegrasikan SAST, DAST, dan SCA ke Anda CI/CD pipelines to scan every code commit otomatis.
- penggunaan policy-based controls to stop insecure code from getting deployed.
3. Secure Your Dependencies
Aplikasi modern depend on open-source software, which can introduce hidden security risks.
- Mengotomatisasikan SCA pemindaian to detect vulnerable third-party libraries before they become a problem.
- Hapus outdated dependencies and apply patches as soon as they become available.
4. Prioritize Vulnerabilities by Risk
Not all vulnerabilities are equal—focus on fixing what sebenarnya penting.
- penggunaan EPSS scoring and analisis keterjangkauan memprioritaskan exploitable risks over minor issues.
- Menurunkan waspadai kelelahan by filtering out low-impact security warnings.
5. Monitor for Anomalies in Real Time
Security threats don’t stop when code is deployed—continuous monitoring is key.
- penggunaan deteksi anomali waktu nyata to track unauthorized changes in CI/CD pipelines and cloud configurations.
- Catch and fix security drifts before they lead to a breach.
What Is EPSS and Why It Matters
Not every vulnerability is a real threat, and security teams can’t fix everything at once. The Exploit Prediction Scoring System (EPSS) helps prioritize vulnerabilities based on real-world exploitability, making sure teams focus on the most likely attacks.
- Cara Bekerja: Instead of treating all vulnerabilities the same, EPSS assigns a skor risiko based on actual exploit trends. As a result, teams can fix critical issues first before attackers take advantage of them.
- Mengapa Ini Berguna: With thousands of new vulnerabilities appearing daily, EPSS filters out non necessary alerts so teams can focus on high-risk issues instead of spending time on minor threats.
- How Xygeni Uses It: To improve EPSS, Xygeni makes sure reachability analysis is included, providing teams to fix only exploitable vulnerabilities sementara avoiding low-impact alerts.
By using EPSS, Xygeni helps security and DevOps teams fix the right issues—faster and smarter.
