I would like to secure as much as possible a computer I am using to sync sensitive data files from work to my home pc. The syncronisation is being done by only 1 software is there a firewall to allow connections to the internet only by that 1 software (and windows updates also) and NOWHERE else so an attacker cant find a weakhole in the home pc?
Also please, what recommendations would you give me so that the home pc is more secure? Are there any tools to block all incoming connections to my pc except from that software and any other security measures I would take? I am very stressed i dont want to loose my job over this thing. What other tools are there for a computer to use when its only for backup and needs maximum security?
Some info about the home pc: it is a desktop used only for the backup purposes and nothing more. I dont even surf the web from it. So no chance of me downloading something (virus etc).
