Background: At my place of work, we're trying to block all unapproved browsers on all Windows machines and the IT Security guys did a search on our internal infrastructure and came up with a list of all the hash values of the installed Verboten browsers, but I noticed that a bunch were missing from their list and as I'm a BOFH, I know that users not liking Edge, Chrome nor Firefox are just going to look for stuff that isn't blocked.
So I told the Security guys to just have a look at the Wikipedia List of browsers and block everything.
Question: Is there an on-line public / commercial database of
all a lot of pre-calculated SHA256 hash values of (Windows) applications available out there that I can point them to instead of having to install myself ~200 applications that are not allowed, calculating the hash values myself and giving it to them or they won't even listen to me?
Note 1: Yes, I know this is an XY problem and we should really be whitelisting, but we're bad at Organisational Change Management and I'm just a mere InfoSec PM, so although I used to be technical, I'm a mere suit nowadays... :-(
Note 2: I tried searching the Internet already but my search didn't reveal anything...
Note 3: Yes, I'll bring up whitelisting on next IT Security meeting I'm part of, but I know where that'll go unless I give extremely detailed instructions on how to do this for browsers only...
