Now that Wifi is being widely adopted, I as many other do have a home router / firewall. Is it the case that it is now not possible for a n attacker to run malicious code (such as buffer overflows) against my machine?
It used to be the case that some script kiddie threatining you across a chat program, could easily retrieve your IP address by typing "netstat -n". Am I right in thinking that if your behind a router / firewall the only address they can retrieve is the IP of your router, hence making your machine invisible to the outside world? This is assuming of course that your port forwarding to the machines services is not setup and the machine is not in the DMZ. Even so, many ISPs now use a proxy which hides even the IP address of my router.
- As long as I don't accept and run malicious files, my machine cannot be accessed?
- If this is not the case, what other threats to I face?
- How can I prevent these threats?
Thank you for your knowledge
