SDLA

Security Development Lifecycle Assurance - an ISASecure certification scheme verifying that a supplier's development processes meet IEC 62443-4-1 requirements.

What is SDLA?

Security Development Lifecycle Assurance (SDLA) is one of the ISASecure certification schemes. It verifies that a product supplier's development processes conform to the requirements of IEC 62443-4-1, which defines secure development lifecycle requirements for products used in industrial automation and control systems.

Scope

SDLA certification evaluates the organization's development processes, not individual products. It covers:

  • Security management: Organization-level security governance
  • Specification of security requirements: How security requirements are defined
  • Secure by design: Architecture and design security practices
  • Secure implementation: Coding standards and practices
  • Security verification and validation testing: Testing methodologies
  • Management of security-related issues: Vulnerability handling
  • Security update management: Patch and update processes
  • Security guidelines documentation: User documentation

Benefits

SDLA certification demonstrates to customers that an organization follows a mature, systematic approach to developing secure industrial products. It is often a prerequisite or differentiator in the OT product market.
