Short Answer 
The Secure SDLC process consists of three key phases: Initiation, where security and privacy requirements are established; Development, which focuses on integrating security into design and architecture; and Implementation, which involves security testing and monitoring to ensure effectiveness. Each phase includes specific activities aimed at identifying risks and ensuring compliance throughout the software development lifecycle.
1. Initiation Phase: Establishing Security and Privacy Requirements
The first step in the Secure SDLC is the Initiation phase, where key security and privacy requirements are defined. This involves identifying the specific risks and compliance standards that apply to the software being developed. Essential activities in this phase include:
- Gathering business and legal requirements
- Conducting risk assessments
- Establishing security policies and governance
2. Development Phase: Incorporating Security Design and Architecture
In the Development phase, the focus shifts to how security can be integrated into the software’s design and architecture. This is crucial for ensuring that vulnerabilities are addressed early on. Key activities during this phase include:
- Creating threat models
- Designing secure APIs and user interfaces
- Implementing secure coding practices
3. Implementation Phase: Performing Security Testing and Configuration
The final step involves the Implementation phase, which centers around security testing and monitoring as the product goes live. This ensures that security measures are effective and maintained. Important tasks in this phase include:
- Conducting penetration testing and vulnerability assessments
- Configuring security settings and controls
- Monitoring application and system behavior for anomalies
