In which domain would you explore software development lifecycle security practices?

The exploration of software development lifecycle security practices primarily falls within the realm of Security Engineering. This domain encompasses the principles and practices necessary to build secure systems and applications. It focuses on integrating security into the software development process from the outset, ensuring that security considerations are part of each phase of the software lifecycle, including design, development, testing, and deployment.

Key aspects of this domain involve the application of secure coding practices, threat modeling, security testing strategies, and the implementation of security controls and best practices throughout the software development lifecycle. By embedding security into the engineering processes, organizations can reduce vulnerabilities and enhance the overall security posture of their software products.

This frame of reference allows for a proactive approach to addressing potential security risks before the software is deployed, rather than reactively trying to fix vulnerabilities after they have been identified. Consequently, focusing on Security Engineering aligns perfectly with the necessity to incorporate security continuously during development.
