The “Operational Technology Cybersecurity Controls” (OTCC-1: 2022) document, issued by the National Cybersecurity Authority in the Kingdom of Saudi Arabia, is a comprehensive regulatory framework specifically designed to protect Industrial Control Systems (ICS) and critical national infrastructure.
These controls aim primarily to raise national readiness to confront the increasing cyber risks targeting industrial operations, and to ensure the continuity of vital services whose disruption could lead to significant negative impacts on national security, the economy, or public health and safety.
This document is a complementary extension of the Essential Cybersecurity Controls (ECC-1: 2018), focusing specifically on the operational and technical aspects of manufacturing, energy, and other utility environments.
The structural framework of the document relies on four fundamental components aimed at comprehensive protection: cybersecurity governance, cybersecurity enhancement (defense), cybersecurity resilience, and external cybersecurity.
These components branch out into 23 sub-components, which collectively include 47 main controls and 122 sub-controls, covering vital areas such as asset management, network security, data protection, vulnerability management, backup, and identity and access management.
The document takes into account four main pillars to ensure the effectiveness of implementation, which are: strategy, people, processes, and technology. These controls apply a tiered methodology to determine the mandatory nature of security requirements based on the facility's sensitivity, dividing them into three levels, starting with “Level 1” for highly sensitive facilities, which includes 151 controls, down to “Level 3” for low-sensitivity facilities, which includes 56 controls. The compliance of entities with these controls is assessed through self-assessment tools and on-site audit visits conducted by the authority, ensuring the actual and continuous application of cybersecurity standards across various vital sectors in the Kingdom.
The document requires entities to integrate cybersecurity requirements into the lifecycle of operational system projects, including factory and field acceptance testing, and to ensure the availability of qualified and trained human resources to handle these complex systems.
