Let me first admit that I am a nobody in computer security - I just know the various threats generally known to public.
I have a Linux Cent OS 7 installed on my computer which is connected to the Internet always - on my personal home network.
I download a lot of stuff like linux softwares, jar files, images, movies etc from the internet.
My question is : Just by connecting to the internet, is it possible for an outsider to steal my files ? Well I know that it is theoretically possible, but I want to know what the outsider will have to do to "Steal" my files - especially when the linux computer is SE Linux enabled with "enforcing" option and the firewall is on.
How easy or hard it is to do this for an outsider ( a remote computer user who is NOT on my network ?
( But i don't know more about the firewall configuration. )
And if you can guide me on any tools available to prevent any of such attacks it would be a real favor.
Thanks in advance.
