Networks are all around us, but do we know how they work? In this series, we’ll look at the basics of computer networking, from hardware components to security practices. This is the fourth post in the series. To read the preceding post, click here.
So now we know how Wi-Fi works, and we know the physical components of a computer network. We know the pros and cons of wireless vs. wired networking.
What’s the next logical question?How do I keep all this stuff secure?
While the information in this post is for everyone, it’s especially good for homes and small businesses that use a Wi-Fi network. Quite frankly, most of the home networks I see are not very secure. I really would recommend that you have a pro, or a knowledgeable friend, set up your Wi-Fi network initially.
That being said, there are some basic changes you can make that will keep your network in much better shape than a straight-from-the-box setup could.
One of the main aspects of network security is controlling access. We’ll get into that a bit more in our next post. Access to wireless networks can be a bit trickier to control. The dude in the parking lot could be hacking into every computer logged onto your network, and no one would realize it because they can’t actually see him.
That, in itself, is scary. So what precautions can you take?
There are other ways to keep your network secure. They have names like MAC authentication, IDS software, and network monitoring, and they’re not for the absolute beginner. But these steps will give you a leg up over many networks.
And if you need professional advice, you can always call on the pros at Techspert Services.
