Within a Communication Service Provider (CSP) operational organization, there are several different departments/groups that are involved in the management of the network and its elements. EMS Security Management refers to the establishment of user accounts/groups with specific access roles and privileges.
A mandatory CSP EMS feature is the ability to create multiple groups to access and manage the network elements plus assign individual staff roles and access permissions. In addition the actions performed by the user should be logged and accessible for review and analysis. The ability to log the actions of users is important especially if there are security violations or user actions need to be reversed.
