EXTERIOR AUTOMATION AND AV SYSTEMS
SECURE ON THE OUTSIDE?
How do you protect data when its on the outside of a property?

kind of design, then you’ll undoubtedly be faced with the prospect of plumbing the internet into it at some point. Even speakers now have IP Addresses and, therefore, will need to sit on your Local Area Network (LAN). So, if you’re putting them outside, you’ll need to extend your IT network in order to accommodate them. Not to mention, of course, all the other component kit that will need to be installed to make any external system a reality. Naturally, you’ll want to be protecting your data network from any kind of hacker that may be lurking somewhere out there in cyberspace. It’s worth remembering that these shifty little characters are not always hiding behind the web and raiding your data virtually. Bear in mind
outside the garden gate. So don’t do the technological equivalent of this by having your data network exposed and vulnerable to attack. So, why is this any different from a standard situation where your LAN is indoors? Well, simply because you’ll have to have your Wi-Fi extended to an external space, and for that you’ll most probably deploy one or two – or more – wireless network extenders. You may even install a Mesh Network to do this. But the considerations will all be the same. Make sure you secure it properly so that these new, high-strength gateways on to your internal LAN are not weak spots in your overall system. I know this is tantamount to stating the obvious, but in

now and then. Change your passwords three or four times a year as well. And if you’re like me in that you hate living your electronic life bound and shackled to a series of increasingly obscure passcodes and PINs, get yourself a copy of KeePass – it’s free! – and store all of your information in there. Other password storage software is available. Hopefully you’ll not be subjected to any unfortunate incursions, but by considering these handful of simple ideas you might be spared that ignominy. Finally, I’d suggest – and this is a general rule of course – that wherever electronic equipment you put outside you had better make sure it’s waterproofed to an industrial standard. Because, at the time of writing, it doesn’t look like it’s going to stop raining any time soon!
