Re: Block Firefox

Hi @idsanalysts,

Now, let us look into On Access 3.JPG and On Access 4.JPG

  1. Subrule type is perfect!
  2. Operations: This looks a bit aggressive in my opinion. However no harm in doing so in this particular scenario. This should work just fine
  3. Targets: This needs to include just (Wildcard). - This means that the action will be implemented at all places/locations.
  4. Essentially, We are blocking the executable Firefox.exe to perform any operation anywhere on the machine.

So the executable maybe present and yet will not be usable by any means!

Re: Block Firefox

Hi @idsanalysts,

Finally, You can use any 1 of the options (Access Protection or Potentially Unwanted Programs) to perform the block. Using both would be overkill. 

Access protection, however gives you an edge of using the MD5 of the process (Firefox.exe) if you are trying to block a specific version!

Please keep us posted on how this goes. I will be more than happy to clarify any further questions you may have on this!

Re: Block Firefox

This still isn't working, but I think it might be due to it being tested on a VM server.

Going to try tomorrow on a users laptop and see what happens.

Will report back.

Thanks for your help

Re: Block Firefox

Hi @idsanalysts 

Thank you for your kind response. It should work, however, I would like to take a look at the policy in place. May I request you to kindly export the policy and please help us with the same?

For exporting the policy, please visit Policy Catalog and kindly export the policy you are applying under Access Protection.

Re: Block Firefox

Hi,

 

Thanks for posting

 

I think you requirement is to stop using the firefox completely in your organization.

 

This can be achieved through ENS web control, where we have browser control policy under ENS web control policy, which you can block the respective browser to stop working with ENS WC enabled clients.

Re: Block Firefox

We're not able to use Web Control unfortunately - it sounds the best option though.
