Access Management

All devices or systems changes, including all administrative functions, should require authentication. Consider using access management technologies to enforce authorization on all management interface access attempts, especially when the device does not inherently provide strong authentication and authorization functions.

Authenticate all access to field controllers before authorizing access to, or modification of, a device's state, logic, or programs. Centralized authentication techniques can help manage the large number of field controller accounts needed across the ICS.

Ensure embedded controls and network devices are protected through access management, as these devices often have unknown default accounts which could be used to gain unauthorized access.

Consider using access management technologies to enforce authorization on all management interface access attempts, especially when the device does not inherently provide strong authentication and authorization functions.

Access Management technologies can be used to enforce authorization policies and decisions, especially when existing field devices do not provide capabilities to support user identification and authentication. ^[1] These technologies typically utilize an in-line network device or gateway system to prevent access to unauthenticated users, while also integrating with an authentication service to first verify user credentials.

Ensure embedded controls and network devices are protected through access management, as these devices often have unknown hardcoded accounts which could be used to gain unauthorized access.

Access Management technologies can help enforce authentication on critical remote service, examples include, but are not limited to, device management services (e.g., telnet, SSH), data access servers (e.g., HTTP, Historians), and HMI sessions (e.g., RDP, VNC).
