Description
User account and privilege validation must be centralized in order to prevent unauthorized access using changed or revoked privileges. CounterACT can implement functions such as traffic filtering, authentication, access, and authorization functions based on computer and user privileges. However, the directory service (e.g., Active Directory or LDAP) must not be installed on CounterACT, particularly if the gateway resides on the untrusted zone of the Enclave.
