How to firewall
Did you know that if your computer is connected to the internet, it is over 131,000 ‘ports’ is that a hacker will be able to have should join? These ports are like doors in a building, and if they are not protected properly, then someone could sneak in without you realizing it. If the hacker does not install a virus, they can add a bit more serious, unnoticed your security software, including the transfer of your personal data. So, as you can see, all these doors to your information? You need a firewall!
Structurally, a firewall is a fireproof wall that shares a building to stop the spread of fire from one area to another. In computers terms, we need to stop the communication between your computer and others on the internet. Total block all Internet communication would be uselees, though, so choose a path, what type of communications you want to receive ans accept. This computer firewalls have rules and filters such as construction firewalls have access doors.
Where do I put this firewall?
Firewalls can be installed on a hardware box (a separate unit or part of your internet modem or router) or software on your computer. Most popular security software packages also have a firewall. A hardware firewall is achieved for a barrier in front of your computer and will also mean that your computer does not expend its valuable resources on the firewall software. It also reduces the risk of the firewall itself compromised because some viruses can try and disable security software features that run on your computer. The disadvantage is that a hardware based firewall can be more expensive and not as easy to configure and maintain if you are unsure to use them.
If Microoft gives me a firewall, I have another one?
The Windows Firewall (on windows XP service Pack 2 and vista) only examies inbound communications coming into your computer from the internet. (for example, if you have some free software to install a hidden evil turns out to have) if you computer is infected, then your outgoing communication with other computers on the internet is not examined or will be filtered. This in turn can make your computer into a source of infection affect your security and internet connection. It is also not recommended that you run more than one software firewall, as this consumers more computing power and can lead to conflicts, so if you disable your security sofrware includes a firewall, the Windows firewall.
If I have a secure wireless connection I need a firewall?
A wireless connection is another way to access the internet and wireless security controls to use this link. This is similar to enable the plug into phone line. Once you are connected, your 131,000 ports are still open to hackers, so you still nedd a firewall. A firewall can be included on your wireless router, but it’s worth to check it.
Why to me so it news?
If you have something specific ( such as installing new software or troubleshooting a problem with the connection), you must temporarily disable the firewall. Software firewalls may warn you that a connection has been established blocked and can try and ask if you want to allow this type of connection in the future. In general, if you have something new, which would probably mean to do to connect to the internet, you can activate the conection either this time or for all future connection attempts. When in doubt, block, so you can always do it later if you find that it is necessary to.
Firewalls provide an increased level of security, which are the minimum standart now to protect your computer. They require a certain level of knowledge or a large computer support staff, so talk to your local computer troubleshooter to ensure that you are protected.
