![]() ![]() If you connect through a home or an office LAN, you are relatively less exposed since the Internet gateway/router you use will most likely limit incoming connections that you don't specifically configure (effectively acting like a limited network firewall). Any complex software such as Windows with mulitple other software running on top, is likely to have many weaknesses unknown to general public - so it is a big risk. This greatly reduces exposure of any security weaknesses. i.e., someone trying to probe / connect to your computer would not be allowed to, without your permission. One of the first thing nearly all firewalls do by default is to limit incoming connections. Possible risk with a fresh Windows install: Security weaknesses (vulnerabilities) due to software defects or incorrect / insufficient configuration.Įxample of what someone might do if it's without a firewall: Probe for those weaknesses without you noticing. So I'll limit myself to one idea and one example. The topic of firewall protections can be big if we go into details. It will be great if someone gives an example/describe of how to hack a computer that has no firewall and has a fresh installation of Windows (remote desktop connection is disabled and a username and password is needed to login into that computer). If you have malware already on your computer and then you turn off the firewall then yes I understand that then the malware will be able to send and receive Command-and-Control traffic.īut if a computer with a fresh installation of Windows has its firewall off then how would you hack it? You will be able to send all the packets you want to that computer but that computer will not know what to do with those packets right? Now I want to understand how does it make my infrastructure vulnerable. Turning off Windows Firewall might make yourĭevice (and your network, if you have one) more vulnerable to You should always run Windows Firewall even if you have anotherįirewall turned on. ![]() Why do people go crazy when the firewall if off? Most sites on the internet say its very dangerous to turn off your firewall and I want to understand why. ![]()
