hello,
I will tell you honestly, if a hacker is targeting you specifically and have the resources (money), time and motivation, he will eventually find a way despite all your security measures.
The best way to protect your sensitive datas are to encrypt them then store them in a unconnected external storage.
If you still want secure your system, a layered security strategy is required (using several software complementing each other).
Please help.
Thanks!
I didn’t find the right solution from the Internet.
