Ports it's like a firewall in your box. If you block everything you can't do a lot of things.

Closing every single of your ports is like not being connected to the wifi.

every listed open ports in system has a type of defined work purpose.so if you aware about it that port range for different application and then try to catogorise each non useffult port and then closing it will help you to safe from dark web attacks..but some times pentesting helps to find out which ports range may harm more and prior..!

This is actually very helpful information. I like how this article tries to bring some awareness to potential vulnerabilities in one's personal computer. Another thing you can do is use a packet sniffer like WireShark to monitor incoming and outgoing information.

I usually put a default drop policy and then allow ports I need, like SSH and HTTP(S) etc. Don't only do the drop policy first though, because you'll lock yourself out of being able to connect through SSH, which I totally haven't done before.

Best way, close all not needed ports and if you need the port you can still open it easily with changing the firewall rules.
But in my opininon a port based firewall is not the ultimative soloution. You should show a package firewall to check incoming and outgoing packages.

I agree, i like to mark my packets so its easier visually to see whats being passed through the firewall.
definitely close 21/22 - most important rule, change default usernames and default ports - if possible.

also i prefer to create time out rules with different stages of the timeout being applied, instead of dropping all traffic.
montior the timeout and take action thereof

I really like the idea of safe guarding against unwanted hack attacks. However, closing off all ports sounds like an extreme measure for a personal or work computer. I would recommend it for hosting servers though.

It is a nice closing way. If you can not open it, you can not enter it yourself (w)

This is actually really useful! Why did I not think of guarding my ports before and using a package firewall? I guess I only pay lip service to security. Yep, I've shut off SSH, Cryptographic services and pretty much everything else Windows needs to connect to the net, but on the bright side I made my pc run faster once I figured out what it actually needs.
