CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X

Implement the Role-Based Access Control (RBAC) feature and follow the SCADAPack documentation sections Security Guidelines for Administrators and Working with Role-Based Access Control. RBAC is the recommended access control mechanism for SCADAPack 47x devices and should be used in place of the Secure Lock feature. The Secure Lock feature is legacy functionality retained for backward compatibility with existing deployments and should only be used where required to support legacy system requirements. Consult the SCADAPack Cybersecurity Guide, including the SCADAPack Hardening and Secured Communication sections. In addition, apply the following standard practices to reduce the risk of exploitation: • Configure network segmentation to restrict access between trusted and untrusted networks. • Enable and implement the RTU firewall service to restrict unauthorized access to device services and reduce the attack surface.
