Problems with FOG client and FIPS validation

Brian David

Fog Version: 1.5.0-RC-9
Fog Client Version: 0.11.12
Server: Ubuntu Server 16.04.3 LTS

We recently used GPO to force all our computers to require FIPS compliant encryption suites whenever using encryption to communicate (this is a requirement for PCI compliance). Unfortunately, this seems to have broken the FOG Client. Here are the relevant log entries:

I don’t suppose anyone else has run into this issue and has any workarounds?

@Joe-Schmitt You better take a look at this one.

Brian David

@joe-schmitt Okay, sounds good. I’ll keep an eye out on future updates and I appreciate the work you do.

@Brian-David could you test this build https://build.jbob.io/Zazzles/nightly/PCI-Compliance-01/Zazzles.dll

To test:

stop the client: net stop fogservice,
replace C:\Program Files (x86)\FOG\Zazzles.dll with the file I linked to
start the client : net start fogservice

And then monitor the client logs / behavior for any more issues.

@joe-schmitt I followed your instructions, but the FOG Service won’t start after the .dll file is replaced. There were two relevant errors in the event log.

@Brian-David thanks for the logs, could you try installing a new nightly build? Steps are as follows:

Uninstall the client on a computer
Under the computer’s host page in the fog dashboard, hit Reset Encryption Data
Download and run: https://build.jbob.io/Client/nightly/11-13-2017-pci-compliance-01/SmartInstaller.exe
Restart the computer

It will likely still fail, but it should be a step in the right direction.

@joe-schmitt Followed your instructions, but unfortunately I am getting the same FIPS error when the client tries to authenticate:

11/15/2017 8:44 AM Data::AES ERROR: This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms.

Joe Schmitt

@Brian-David alright, thanks for testing. This will require a bit more work than I was hoping for it seems.
