Description

Authorization for access to any network element requires an approved and assigned individual account identifier. To ensure only the assigned individual is using the account, the account must be bound to a user certificate when PKI-based authentication is implemented. This requirement applies to ALGs that provide user authentication intermediary services (e.g., authentication gateway or TLS gateway). This does not apply to authentication for the purpose of configuring the device itself (device management).
