User credentials sent in clear text

Hi. I have using the check_mk version 1.6.017.
My company use some sort of security checking device, and get two security breach.

One of them is “User credentials are sent in clear text”.

Is there any check_mk configuration that can be applied to fix this?

the other security fix are vulnerable javascript library, which is jquery.

Which credentials are meant by this? If you are talking about the login process to the checkmk site, then switch to HTTPS.

Beside the HTTP/S problem mentioned from @Dirk it can also be if used the LDAP connection.
But this can also be changed from you side to encrypted communication.
All the used communication channels can be set to encryption but you must do it.
