Security can’t wait until the final testing phase. If you want to build secure, resilient apps, you need to think about security from day one. That’s where understanding what are the phases of the Software Development Life Cycle (SDLC) becomes critical. By embedding SDLC security into each phase, from planning and design to deployment and maintenance, you create a Secure Software Development Life Cycle (SSDLC) that reduces risk, cuts costs, and keeps your software ready for real-world threats. In this guide, we’ll walk through each phase of the SDLC and show you how to make security a built-in feature, not an afterthought.
hoomaopopo SDLC and the Secure Software Development Life Cycle
The Software Development Life Cycle (SDLC) provides a structured approach for designing, building, testing, and deploying software. However, traditional SDLC often treats security as an afterthought. This is where the secure software development life cycle (SSDLC) comes in, integrating security into every phase to ensure your software is resilient against modern cyber threats.
SDLC Security: The Foundation of a Secure Software Development Life Cycle
E like me ka National Institute of Standards and Technology (NIST), security should be integrated across all phases of the Software Development Life Cycle, from planning to maintenance. By embedding SDLC security practices into the development process, teams can address vulnerabilities early, minimize risks, and avoid costly fixes later.

The Software Development Life Cycle (SDLC) is a structured framework that clearly outlines the stages of creating software, starting with careful planning and moving through development, deployment, and maintenance. Moreover, in the software development lifecycle, each phase includes specific activities, goals, and deliverables. As a result, these steps ensure that the software is developed efficiently and effectively while meeting all required standards. By following this clear framework, teams can create high-quality software that aligns with functional and business needs.
What are the Phases of Software Development Life Cycle and Their Security Requirements?
Every phase of the Software Development Life Cycle (SDLC) has unique security challenges. Knowing what are the phases of software development life cycle helps you integrate SDLC security into every step. By adopting a Secure Software Development Life Cycle (SSDLC), you can catch vulnerabilities early, reduce risks, and build better software.
Here’s how security fits into each phase of the software development life cycle and how Xygeni helps make it seamless:
1. Planning and Requirement Analysis
This phase forms the foundation of the project. Teams define the project’s scope, gather requirements, and assess potential risks. Understanding what are the phases of the software development life cycle starts with strong planning, and adding SDLC security at this stage prevents vulnerabilities later.
Kūlana palekana: Threat modeling and gathering security requirements are key here. Tools like ʻO Xygeni Application Security Posture Management (ASPM) provide full visibility into potential risks by automating the discovery of software assets. At the same time, ʻO Xygeni Software Supply Chain Security (SSCS) ensures any third-party or open-source components meet security standards, reducing supply chain risks before development even starts.
2. Design
In the design phase, teams map out the system’s architecture and decide how the software will function. Critical security decisions, such as protecting sensitive data, controlling user access, and mitigating threats, take center stage.
Kūlana palekana: Secure architecture design and updating threat models. Xygeni’s Infrastructure as Code (IaC) Palekana scans cloud and system architectures for misconfigurations, ensuring security flaws don’t get embedded into your design. Additionally, Xygeni’s Secrets Security helps safeguard sensitive information like API keys, credentials, and passwords throughout this stage.
3. ulu ana
This is where the actual coding happens, making it one of the most vulnerable phases for introducing security risks. Poorly written code or insecure components can create significant issues if not addressed early.
Kūlana palekana: Secure coding practices, static application security testing (SAST), and software composition analysis (SCA). ʻO Xygeni ASPM actively monitors the code during development, flagging risks in real-time so developers can fix issues as they arise. Auto-Remediation, part of Xygeni’s Open Source Security suite, automatically resolves vulnerabilities in open-source components before they reach production. Meanwhile, Ka ʻIke ʻana i nā polokalamu ʻino i ka manawa maoli protects dependencies and third-party libraries, while Palekana huna ensures no sensitive data accidentally makes its way into the codebase.

In the testing phase of the polokalamu holomua ola pōʻaiapuni, teams validate functionality and check for vulnerabilities. Thorough testing ensures no security risks make it to production.
Kūlana palekana: Dynamic application security testing (DAST), penetration testing, and vulnerability scans. During this phase, ʻO Xygeni ASPM uses exploitability metrics to highlight the most critical risks, helping teams prioritize fixes efficiently. Ka ʻIke ʻana i nā polokalamu ʻino i ka manawa maoli continues to scan for threats in third-party components, while SSCS ʻike anomali monitors for unusual behavior that could signal hidden vulnerabilities.
5. kuhikuhi i ka hana
This phase releases the software into the production environment. Teams must ensure the deployment process is secure to avoid introducing new risks during the transition.
Kūlana palekana: Secure configurations, post-deployment vulnerability scans, and intrusion prevention systems. In addition, ʻO Xygeni Open Source Security hoʻopau ensures that third-party components remain secure even after deployment. Furthermore, Auto-Remediation fixes vulnerabilities in live environments without manual intervention. Meanwhile, SSCS continuously scans for new threats, keeping your production environment secure.

The job doesn’t end after deployment. Ongoing maintenance addresses new vulnerabilities, applies patches, and ensures the system stays secure against evolving threats.
Kūlana palekana: Vulnerability management, patch management, and continuous monitoring. ʻO Xygeni ASPM provides real-time security monitoring to quickly detect and resolve emerging issues. Coupled with Ka ʻIke ʻana i nā polokalamu ʻino i ka manawa maoli, Xygeni helps protect your software against new risks in third-party components, ensuring long-term security.
The Benefits of a Secure Software Development Life Cycle
Adopting a Secure Software Development Life Cycle (SSDLC) isn’t just about making your software secure—it’s about working smarter and building better applications. By integrating SDLC security practices into every phase of development, teams gain a range of benefits:
- Reduce Vulnerabilities: Catching security issues early helps prevent major risks from reaching production.
- ʻO nā kumukūʻai haʻahaʻa: Fixing vulnerabilities during development is far cheaper than patching them post-release.
- Improve Security Posture: SSDLC builds resilience into your software, preparing it for evolving threats.
- Achieve Compliance: Meet security standards like GDPR, HIPAA, and PCI DSS without last-minute scrambling.
How the Secure Software Development Life Cycle (SSDLC) Transforms Software Security
Understanding what are the phases of the software development life cycle is the first step to creating secure and reliable software. When you adopt a Secure Software Development Life Cycle (SSDLC), you make security a core part of your development process. From planning and design to maintenance, adding SDLC security into every phase helps your team catch vulnerabilities early, lower costs, and stay ahead of evolving threats.
ʻO Xygeni makes SSDLC adoption straightforward. Application Security Posture Management (ASPM) gives you real-time insights into risks so your team can fix issues quickly. Software Supply Chain Security (SSCS) keeps third-party and open-source components safe. With Auto-Remediation, you resolve vulnerabilities instantly and keep your focus on building great software.
