Identity and Access Management (IAM) in the Software Development Life Cycle (SDLC) is the guardrail for who can do what, when, and where in your systems. If it’s weak, your entire pipeline is exposed. If it’s strong, you can ship with confidence.
IAM in SDLC means embedding identity verification, role-based access control, and permission auditing into every phase—requirements, design, development, testing, deployment, and maintenance. It’s not an afterthought. It’s code and process that travel together.
Requirements Phase: Define user roles, privileges, and compliance constraints early. Knowing the exact access model upfront prevents costly rewrites later.
Design Phase: Architect systems with least privilege as a core rule. Plan API authentication, single sign-on (SSO), and multi-factor authentication (MFA) before a single endpoint is exposed.
Development Phase: Implement secure coding practices for credential storage, token handling, and session management. Use IAM libraries and services that support modular integration into existing codebases.
