[THIN] Re: ICA Client Encryption

Yes, Briforum rocked!!

If all external connections are AG then the outside is “protected”, the question is how important is it to encrypt traffic on the inside. Keep in mind that ICA is not your biggest internal exposure, the html and xml stuff between WI, AG and the XML service is actually more vulnerable. To secure this stuff you need certs between these boxes. As far as 128 ICA encryption I would always turn it on, the few % of CPU it might take is worth knowing that the ICA traffic is secure as it travels around, also consider encrypting authentication in any scenario .

Subject: [THIN] ICA Client Encryption

 

Hello gang, BriForum 2008 at Chicago Navy’s Pier rocked!!  What a relaxed and awesome venue!

 My new boss wants to put the ICA (XenApp Client 10.20) encryption level from our previous 128-bit encryption to Basic encryption when we migrate to our new XenApp 4.5 Farm.  In the past we have always used 128-bit encryption due to security to reduce any chance a hacker could intercept our ICA TCP/IP packets and jeopardize our Citrix Farm / Corporate data.  We are an international business with over a 250-server farm so it is imperative we get it right!

We use CSG today for our External Citrix connection and we are in the process of migrating to Access Gateway both internally and externally.

What is everyone else using for ICA client encryption and/or can you point me to a whitepaper or recommendation site what is the best practice on ICA Client encryption?  I guess I am old school and maybe I am being stupid in recommending 128-bit encryption on the ICA client and I would like one of experts in this list to guide me in the rigiht direction and ease my fears that Basic ICA encryption is what should be used!

Thank You in advance for your assistance.
