Disable the usage of old ciphers like RC4/RC5 in Linux VDA

[Steffen Valentin1709160582]

To improve security my companys security department wants old ciphers to be disabled and not to be used when connecting to citrix machines.

 

For windows os machines it was quite simple: https://support.citrix.com/article/CTX309214/disabling-rc4-cipher-on-citrix-servers

 

But how would be the way for linux machines?

 

We do not want to enroll any certificates.

Any help is appreciated.

 

Thank you.

Check this article, it outlines a bit on to what you need to disable for RC4, it looks like the VDA uses it primarily for AD connectivity.

Thank you for your answer.

 

But I ment the ciphers used in the communication between Workspace App and VDA.

This seems to be RC5 on Linux systems, and this should be disabled.

 

Maybe you have futher ideas.

 

Thank you
