Cerberus FTP Server
Client Certificate Verification
Features > Access Protection > Client Certificate Verification
Available in:
Cerberus FTP Server can be configured to require clients to verify themselves using digital certificates for SSL/TLS connections. When given a Certificate Authority (CA) certificate list, Cerberus will verify that the client certificate is signed and valid for the given Certificate Authorities. Any FTPS or HTTPS connection attempts without a valid certificate will be denied when this option is selected.
​

For FTPS, FTPES & HTTPS Connections

Added Layer of Authentication Security
Additional Certificate Verification Options
- Certificate Revocation Lists: If the administrator specifies a CRL file, Cerberus will check the CRL file to make sure that the client certificate hasn’t been revoked.
- Post-Verification Client Certificate Checking: Cerberus can be configured to require the certificate Common Name (CN) to match the user’s username. If this option is enabled, and the client common name does not match the user’s username, then the connection request will be denied.
Creating Digital Certificates for Clients
Several tools for creating digital certificates currently exist. The OpenSSL command line tool provides a configurable option for generating SSL certificates that can be used for client certificate authentication.
