I am working on my incident response plan and one part of that is to blacklist a file on all clients. How do I do that in F-Secure Policy Manager? Can I do that? I read some older posts (from 2015) that said it could not be done which seems strange. I guess one way is to upload to F-Secure via their "Submit a sample" but if we talk about a malware outbreak (or similar) within my company I pretty much count seconds and Submit-a-sample usually takes hours to blacklist.
Any suggestions? I am thinking about this the wrong way perhaps.
Any input appreciated.
Please check the new Application Control feature possibilities in latest Policy Manager/Client Security 14 version. It may fit your requirements.
Interesting! I will look into that in more detail. A question about that: have anyone any experience with enabling this rule? And with experience I mean mainly bad experience, i.e. blocking legitimate things. Otherwize this seems like a nice control to have in place for stopping all the malicious Office documents. Thanks!

Yes, I understand but regarding "and MS has disabled this feature by default since then." that is way to easy for users to cirumvent so I need a block for that. No legitimate use for starting powershell from Officedocument in my environment as far as I know. Is there ever I wonder?
