A few years ago, just when computer security software companies thought they were beginning to have the whole PC security thing figured out, a major shift in computer usage occurred, which threw the entire industry on its head. Specifically, I’m talking about laptops, and the now ubiquitous wireless networking tools that go along with them.
Just a short time ago in technology terms, laptops were slow and clunky, hardly suitable for the type of intense Web usage that desktop computers could handle. Now, things have changed. Laptops are capable of all of the same things that desktops can do, perhaps even more. Many people are choosing to use laptops as their primary computers. Many households now have no desktop at all, instead relying upon multiple laptops all connected to the same wireless network. Quietly, the way we use computers and the Internet has been changed by laptops.
For these reasons, laptop security is a major new challenge for software companies to deal with. Although laptops do closely resemble desktops in most of the important ways, everything is subtly different. The hard drives are constructed differently, as are most of the other mechanical components.
Meanwhile, of course, wireless networking presents a whole world of issues that were only touched upon by security systems of the past. In short, laptop security must be closely monitored, and proper software must be in place in order to prevent infection from Web threats.
Essentially, in order to be connected to a wireless network, a laptop must open itself up to floating signals in the atmosphere. Of course, wireless systems are designed so that laptops only communicate with an authorized signal, but it is always possible for hackers and online troublemakers to find ways to tap into this authorized signal.
This can be dangerous for a variety of reasons. Perhaps most ominously, wireless networks can be used to steal private information from computers, which criminals can use to make illicit purchases, or even for identity theft. This is why, when we enter information on the Web, most social security numbers, passwords, and credit card numbers are encoded with asterisks — but this method is not fool proof.
To ensure that your laptop is as safe as it can be on your wireless network, make sure you are using a security enabled network that requires a password to log on. Meanwhile, it’s important that you only connect to that network. In almost any city, it’s easy to find numerous wireless signals just floating around, but this doesn’t mean that we should connect to them. Yes, in certain circles it is popular to use pirated wireless signals for free, but this is always a bad move, with serious risk involved.
Also, even though a huge aspect of wireless networking is its convenience and ease of use, it’s always a good ideal to switch your network off at night or when the network is otherwise not in use. For laptop security reasons, it’s always a good idea to turn off your laptop’s wireless receiver when you are not using it. After all, it only takes a few seconds to turn these back on, so the convenience factor is not lessened by switching them off when they’re not in use.
Finally, do not under any circumstances use a wireless network without having the proper laptop security software in place. At the minimum, every laptop user should have a firewall, plus antivirus and antispyware software. Viruses and spyware can really bring down a computer, and that’s why a firewall is so important in preventing unwanted intruders from entering your hard drive. All of these measures are necessary to optimize your laptop security.
