2. Design

In the design phase, security engineers collaborate with architects and developers to:

  • Review and validate system architecture for security considerations
  • Recommend secure design patterns and best practices
  • Conduct threat modeling to identify potential vulnerabilities

3. Development

During the development phase, security engineers work closely with developers to:

  • Provide guidance on secure coding practices
  • Conduct code reviews to identify security flaws
  • Implement security controls and mechanisms

4. Testing

In the testing phase, security engineers are responsible for:

  • Performing security testing, including penetration testing and vulnerability assessments
  • Analyzing test results and providing recommendations for remediation
  • Verifying that security requirements are met

5. Deployment

During deployment, security engineers ensure that:

  • Security configurations are properly implemented
  • Access controls and authentication mechanisms are in place
  • Monitoring and logging systems are set up correctly

6. Maintenance and Operations

In the maintenance and operations phase, security engineers are involved in:

  • Monitoring systems for security incidents
  • Applying security patches and updates
