NetworkWorld has an interesting article entitled How to use electrical outlets and cheap lasers to steal data. The article discusses a presentation that will be held at the Black Hat USA conference later this month.
The deal is that two researchers are supposedly going to demonstrate how keystrokes can be read from a remote computer using either a laser, or signals transmitted over the ground line coming from a nearby computer.
While these techniques might be interesting to know about, somehow I think we have bigger things to worry about.
Read on to see what I mean…
Many people these days use a Wi-Fi (IEEE 802.11) router, or they have a broadband modem with built-in wireless. It’s amazing to me that in this supposedly “high-tech” and “high-security” age, many people still are completely unaware just how wide open their home network really is.
With a Wi-Fi modem, usually your provider will be smart enough to lock down your wireless connection for you. But if you bought a wireless router or access point and set it up yourself, there are a few things you should know to keep others from “stealing” your connection and using it for nefarious purposes…
Everyone is totally crazy about security these days – especially computer security. We’ve all got antivirus software, a firewall, spyware scanners, and god knows what else loaded up on our PCs to protect ourselves from the “evils” of a networked world.
Some of us choose to use certain operating systems that we believe are inherently secure, while the reality is quite different. I remember hearing all about how “ultra-secure” OS X Tiger was in comparison to Windows XP. I know a lot of people who believed this, and who even went out of their way to harp on XP and how insecure it was. Well, there have been numerous updates for Tiger and Leopard that were sent out from Apple HQ. Guess what? There were scores of security vulnerabilities in OS X. What really might shock you is that the vulnerabilities in OS X read like a list of XP security holes (see here and here and here). That’s right, just because Apple tells you OS X is safer doesn’t mean that it’s actually true! Go figure!
Of course, there’s also Linux. In some respects, Linux is safer. In others, it’s no different than XP and OS X. Personally, I prefer Ubuntu and Vista at the moment. But the bottom line is that when it comes to security, it’s up to you to keep your data safe. The first and best way you can do that is to create and use strong passwords!
