Is it possible to lockdown FIPS mode on in an Enterprise environment?
My company is bound by rules that state we cannot use a browser that doesn't have FIPS enabled and it has to be locked on so a user cannot turn it off. Is this possible with Firefox. I have found some third party group policy templates but they do NOT address this FIPS issue.
See all the security configurations that need to be on or off here: https://support.mozilla.org/en-US/kb/Configuring%20Firefox%20for%20FIPS%2... - the ui may be out of date and there is also a fips entry that has been added.
It is possible to use a cfg file to lock preferences: http://kb.mozillazine.org/Locking_preferences
Hope that helps.
FIPS mode is stored in the secmode.db and requires that a MP is set to normally enable it.
You can only disable FIPS once is has been enabled by deleting the keys.db file and the signons.sqlite file. As this will remove all stored passwords that is usually not an option that most would follow. I don't know of a way to prevent this and even if you would set the secmode.db file to read-only then this file can be deleted as well.
FIPS requires to disable some cypher suites, but I don't know which ones in current Firefox releases. Prefs can be locked however like posted above by using a mozilla.cfg file.
You could consider to ask in the newsgroup mentioned to the above posted MDN article if this is possible.
