Overview of secure PLC coding practices to improve the security posture of Industrial Control Systems (ICS) by leveraging native PLC/DCS/SCADA features. Includes guidelines for engineers creating software (ladder logic, functional charts) and highlights the broader benefits for reliability, debugging, and maintenance.

Overview of secure PLC coding practices inspired by Secure Coding Practices for IT, providing guidelines for engineers creating ladder logic and functional charts to improve the security posture of ICS/OT by leveraging native PLC/DCS/SCADA capabilities. Emphasizes that more than security expertise, familiarity with PLCs, their logic, and the underlying process is essential.
