A new standard covering the secure product development lifecycle has been ratified, officially making static code analysis, software composition analysis, and malformed input testing part of the requirements.

Known officially as ISA-62443-4-1 Security for industrial automation and control systems Part 4-1: Secure product development life-cycle requirement, it is part of a larger certification program designed to assess a supplier's product development lifecycle processes for industrial automation control systems. ISA and IEC standards are used by various industries and are often mandated by law in Europe.
