OT Security Policies and Procedures

After completing the security risk assessments and gathering the information necessary to understand your OT security baseline, the next stage of a comprehensive industrial cyber security program is to create a set of well-defined policies and procedures.

Policies and Procedures Development

Security documentation, along with management support, is the cornerstone of any Operational Technology (OT) cyber security program.

Policies and procedures will define the security organisation and the workflows, describing the specific roles and reporting structures that should be in place to effectively policies-and-compliancemanage cyber security technology and bridge gaps between people, process and technology. Policies and procedures will cover areas such as:

  • Asset management
  • Access control
  • Incident management
  • Business continuity plans
  • Compliance management
  • Communications management
  • Security system maintenance

We have a set of 36 policy and procedures templates available following our best practices and the IEC-62443 standard, ready to be shared with you. It takes approximately 24 months to write a complete set of policies and procedures; however, with our templates available, you could have a customised set in 6 months.
