How To Protect Your Home Network From Security Threats

Technical jargon, is a part of our daily lives, not only in the workplace and at home. If you have setup your CompTIA Security+ certification at home, you probably know all about wireless cards, routers and firewalls. Most computer components are easy to install and get set up to provide a secure home networking and security. An Internet connection may mean connectivity for each computer in the house.

However, you must ensure that the comptia network is safe from hackers and viruses, which can destroy computers and result in irreplaceable data loss. Start by reading the manual of each network product you have since they typically go into great detail about security configurations. But there is still more you need to know.

The first thing you should do is rename the standard administrator account and password since it is likely quite common and would be easy to find. Router ports are basically network numbers which is used by some applications to distinguish traffic. For instance, port 80 is used for web browsing and is the standard for HTTP.

In order to make your ports secure you may want to forgo dynamic IP addresses and purchase a static IP address. This means that you can specify which IP addresses generate traffic leaving your network. This is especially important if you have a wireless network since someone next door can potentially use your network course to get onto the comptia certifications Internet. By specifying which IP addresses may do that youíre preventing this from happening. This is especially important if you live in an apartment building since using someone elses network is surprisingly easy.

Port 80 should be configured to accept all incoming traffic. Some corporations specify which IP addresses can come into the network but this is very time consuming and labor intensive. You will also need to open port 25 for outgoing mail (SMTP) and 110 for incoming mail if you are using a desktop email program.

Once you have your router setup as described above youíre essentially good to go. There are some extra settings you may need to concern yourself with such as ftp ports, but this can leave your network open to attack.

If you have a wireless network, take security one step further and lock it down. If you have an unsecured network anyone within range can access the Internet via your connection. Not only can this severely slow down your own Internet access, but it is dangerous to have someone surfing and downloading who knows what in your name. Most A+ training course manuals explain in detail how to configure your wireless security.
