Secure Development Lifecycle

Overview

Codexium’s Secure Development Lifecycle (SDLC) ensures that security is treated as a first-class requirement, not an afterthought. Controls are embedded into requirements, design, coding, testing, and deployment.

Secure Requirements & Design

• Security and privacy requirements captured alongside functional requirements.
• Architecture reviews and threat modelling to identify assets, trust boundaries, and mitigation strategies.
• Designs based on least privilege, segregation of duties, and defense in depth.

Secure Coding Practices

• Use of secure coding standards and vetted libraries.
• Robust input validation and output encoding.
• Consistent error handling that avoids data leakage.

Code Review & Testing

• Peer review required for all changes to protected branches.
• Automated pipelines with unit, integration, and regression tests.
• Static analysis and dependency vulnerability scanning.

CI/CD & Release Management

• Authenticated CI/CD pipelines with role-based permissions.
• Deployments based on immutable, versioned artifacts with rollback strategies.
• Change control for high-risk releases, often with canary or staged rollouts.

Training & Awareness

Engineers receive periodic training on secure coding, emerging threats, and incident lessons learned. Internal playbooks capture proven patterns for authentication, secrets handling, and other critical topics.

Shared Responsibilities

Client

• Provide security and compliance requirements for the project.
• Participate in design and risk reviews where appropriate.

Codexium

• Operate and continuously improve the SDLC.
• Ensure engineers follow secure coding, review, and testing practices.

Cloud Provider

• Provide secure CI/CD and artifact management tooling.
