IP adress is critical for computer security?
I think so, it is like home address.
if someone wnat to break into your house, he needs to know you address, if he knows, he may can do it.
also if a hacker wants to hack into your pc, he need to know your IP address, if he knows, he may can do it.
am I right?
Yes. But you lock your doors etc at home and you take security measures on your PC to help prevent access from unauthorized persons.

That is what firewalls are for. Not using them properly or going to “bad” sites or opening strange emails will obviously open you up for attacks. A knowledgeable user is seldom a victim.
Actually, a computer hacker doesn’t necessarily need to know the IP address of your computer in order to hack into things or steal your personal information.
If a hacker were to send an infected file to someone and they opened it, it is possible that their computer could become infected with a computer virus or other malicious file or program, which may cause a variety of problems, such as their personal information being stolen.
In order to prevent your computer from becoming infected with a computer virus or other malicious file or program or from being accessed by a third-party, I would suggest that you have a firewall, as well as run frequent antivirus scans and antispyware or antimalware scan.
If you’re using Windows, you may already have a built in firewall, called the Windows Firewall, which may have came on your computer.
If you would like to check the Windows Firewall’s settings, you should be able to do so by going to the Control Panel and then clicking on “Check this computer’s security status”, which is located under the “Security” section.
From there, you should be able to enable or disable the Windows Firewall, as well as check and manage your other security settings.
However, if you don’t have Windows Firewall installed or would like to try using a different firewall, perhaps you should try using Comodo Firewall, which can be downloaded for free from the link below.

If you need a free antivirus program, I would recommend that you try using Microsoft Security Essentials, which can be downloaded from the link below.

If you need a free antimalware program, perhaps you should try using MalwareBytes, which can be downloaded from the link below.

Both of these programs are free and do not require that you pay to renew any subscriptions.
Also, perhaps you should try using Mozilla FireFox, which is a free browser that is safer than Internet Explorer and can also be customized with a variety of free add-ons and themes. If you’d like to try using Mozilla FireFox, it can be downloaded from the link below.

Good luck and I hope I helped you!
there 3 points that are critical to computer security:
1. F/W
2. AV or ISS
3. your computer.
the first two are first line of defense of your computer or computers. Once a hacker or group of hackers penetrate or break your 1 line of defense they own your IP address as well as you computer. What he/she/they will do with info9rmation that is on your computer that’s another question.
usually they make those victim computers an electronic zombies spreading: spam and/or DDoS
