You mean you close open ports?
What OS are you running? And are all these firewalls hardware or some software?
Some software firewalls will give you real time pop ups if port scanning is going on or program trys to connect to the internet where a router firewall cannot to this.
Or lock your computer when you go to the bathroom or Lunch break so all ports even port 80 will be close when you lock it gone to the bathroom or Lunch break .
Some people even shut down the modem and router also unplug the ethernet cable at night.
Some people jut use the router firewall some people want software fire wall and some people both.
Some people use program snort that the ability to perform real-time traffic analysis and packet logging on Internet Protocol (IP) networks. Snort performs protocol analysis, content searching, and content matching. The program can also be used to detect probes or attacks,buffer overflows, server message block probes, and stealth port scans.
In past 10 years of using computer 6 times people tried to hack me.
