Evidence must include the documented processes that collectively include each of the applicable requirement parts in CIP-004-6 Table R4– Access Management Program and additional evidence to demonstrate that the access management program was implemented as described in the Measures column of the table.CIP-004-6 Table R4– Access Management Program Part Applicable Systems Requirements Measures 4.1 High Impact BES Cyber Systems and their associated: EACMS; andPACSMedium Impact BES Cyber Systems with External Routable Connectivity and their associated: EACMS; andPACSProcess to authorize based on need as determined by the Responsible Entity except for CIP Exceptional Circumstances: 4.1.1. Electronic access; 4.1.2. Unescorted physical access into a Physical Security Perimeter; and 4.1.3.

Examples of evidence may include but are not limited to: Dated documentation of the verification between the system generated list of individuals who have been authorized for access (i.e. workflow database) and a system generated list of personnel who have access (i.e. user account listing) orDated documentation of the verification between a list of individuals who have been authorized for access (i.e. authorization forms) and a list of individuals provisioned for access (i.e. provisioning forms or shared account listing).CIP-004-6 Table R4– Access Management Program Part Applicable Systems Requirements Measures 4.3 High Impact BES Cyber Systems and their associated: EACMS; andPACSMedium Impact BES Cyber Systems with External Routable Connectivity and their associated: EACMS; andPACSFor electronic access verify at least once every 15 calendar months that all user accounts user account groups or user role categories and their specific associated privileges are correct and are those that the Responsible Entity determines are necessary. An example of evidence may include but is not limited to documentation of the review that includes all of the following: A dated listing of all accounts/account groups or roles within the system;A summary description of privileges associated with each group or role;Accounts assigned to the group or role; andDated evidence showingverification of the privileges for the group are authorized and appropriate to the work function performed by people assigned to each account.CIP-004-6 Table R4– Access Management Program Part Applicable Systems Requirements Measures 4.4 High Impact BES Cyber Systems and their associated: EACMS; andPACSMedium Impact BES Cyber Systems with External Routable Connectivity and their associated: EACMS; andPACSVerify at least once every 15 calendar months that access to the designated storage locations for BES Cyber System Information whether physical or electronic are correct and are those that the Responsible Entity determines are necessary for performing assigned work functions. An example of evidence may include but is not limited to the documentation of the review that includes all of the following: A dated listing of authorizations for BES Cyber System information;Any privileges associated with the authorizations; andDated evidence showing a verification of the authorizations and any privileges were confirmed correct and the minimum necessary for performing assigned work functions.
