is disabling SSL2 + 3 possible on GS752TPv2

Hi all,

 

Is it possible to disable SSL2 and 3 on GS752TPv2??We have a Nessus vulnerability scan highlighting that this switch is using unsecure SSL version.

 

Thx

Ronnie

  • True, and asked several times recently. As log as no https connection is established using SSL2 or 3 (decent browsers won't use it), there is no risk for exposing data. So no rush...

      True that clients would try highest protocol and crypto first but i guess someone wanting to exploit ssl2 and 3 vulnerability would find a way to force that protocol.

      But i take it is not possible?

        Sure one could force the protocol to be used on the client side, then e.g. login, while capturing the data transferred - what require again physical access to the data path. So how real is that in your environment? Do you access the switch using https in plain connection mode (off a VPN) over the wild Internet or an uncontrolled connection?

         

        Look, I don't deny these obsolete stuff must be removed (not just disabled)...  YeZ please, what is the status for updating al the maintained switches supporting https?
