8.25 Secure Development Life Cycle

Rules for the secure development of software and systems should be established and applied.

The Secure Development Life Cycle (SDLC) in information security refers to a process that organisations use to ensure that their software and systems are developed and maintained with security in mind. The SDLC is a methodology that organisations use to identify, assess, and mitigate security risks throughout the entire software development process.

The SDLC typically includes the following phases:

• Planning: During this phase, the organisation defines the scope of the project, and outlines the security requirements that need to be met.
• Analysis: During this phase, the organisation identifies potential security threats and vulnerabilities, and assesses the risks associated with them.
• Design: During this phase, the organisation designs the system, taking into account the security requirements and risks identified during the analysis phase.
• Implementation: During this phase, the organisation develops and tests the software, and integrates security into the system.
• Testing: During this phase, the organisation conducts a variety of testing to ensure that the system meets security requirements and that it is free of vulnerabilities.
• Deployment: During this phase, the system is deployed into the production environment.
• Maintenance: During this phase, the organisation monitors the system, updates it with new security patches, and makes any necessary changes to maintain the security of the system.
• Retirement: During this phase, the organisation decommissions the system and securely wipes data
