Have you ever wonder when you open your computer something is not right and you have no idea how it happen?
This are things that you should not do:
- Exposing your public ip
- Creating weak password or forget to change default password
- port forwarding with default port
- not enable block failed multiple attempts
- Don't disable your firewall in your computer
Exposing your public ip - I know we sometimes experiment and also want to access our routers outside, access our nas or data outside, since you just follow the tutorial we forget changing settings etc, all this things can expose your ip outside, I once port forward a test lamp and as i check on the server there is someone trying to brute force, the server, which if succeed can expose a lot of things.
Creating Weak Password - Creating weak password can lead to hack and steals information, keys etc in your computer, not changing password on your router can also a big problem if hackers can access it, changing port or use vpn can be better, or don't allow access outside.
Port forwarding - if your going to port forward makes sure to change your default port so that it will not be easily be access and brute force
Not enabling a security features for access Enable security features in your router/computer like block multiple attempts.
Dont disable your computer firewall - This feature is their with a purpose, so don't just disable this one virus can just get in your computer without knowing when this is disable, curious people disable this one since they are having problem, but the real problem is when you disable the firewall and allow a worm or malware to get in the system, doing the damage and steals your data.
There are lots of things you should not do in your computer, do things when its neccessary do make an extra care doing this because, once your computer has been infected, you don't have any idea what data has been steal and will be expose.
Having a decent AntiVirus, a clean network, and a router having rich features is better you can also try opensource firewall if you want, but having said its up to the users don't click anything or install, download things you don't know, to be sure.
