Configure Adapter to blacklist user-ids

Hi Team,

IBM Sterling Secure Proxy Configuration Manager must have an option at adapter-level to blacklist user-ids.


By default the incoming traffic [Protocol: SFTP] does prompt for a password. Business Security admins are increasingly receiving junk user-id hitting IBM SterlingSecure Proxy and also being prompted for a password, which then gets rejected.

Requested enhancement is to have the SecurreProxy to provide an option for each adapter, where:

  1. User Validation is done first by checking blacklist against each adapter

  2. If User validation fails, block the user and do not prompt password.

  3. If User validation succeeds, then proceed prompting for password.

What is your industry? Healthcare
How will this idea be used?

Idea helps avoid authentication attempts crisscrossing the Firewall and through Internal network.

If implemented, the Junk authentication attempt will not appear asking for password in Firewall scanner logs.

    Thank you for taking the time to provide your ideas to IBM. We appreciate your willingness to share details about your experience and your recommendations.

    Sterling Secure Proxy currently blacklist the users already at the engine level. Intentionally we have designed it in a way that even the blocked users will be asked for passwords followed by which a generic message "authentication failed" would be shown. This ensures that there's no knowledge to the external user whether their IPs are blocked.

    If you have any additional feedback, thoughts or ideas, or if there is anything else I can do, please do not hesitate to reply to this message to continue the conversation. Appreciate your patience.
