Eight easy steps to iPhone security

Apple's irresistible iPhone is a prize for thieves, vandals, and hackers too. Follow these tips to protect your device and its data.

8. If you use the iPhone professionally, use Exchange Server for its back end. Exchange Server keeps backups of all messages and mail settings, and most important in my book, it supports remote device blanking. In fact, Exchange is the only way to blank a remote iPhone. One drawback of remote blanking from Exchange Server is that it takes several hours -- eight, by Apple's estimation. But because the mail client is always running, a remote blank can only be circumvented if the thief is smart enough to disable your Exchange account before you discover your iPhone is missing. That's something he can't do because, of course, you've PIN-locked your device. Make sure that you or your IT department knows how to blank your device, and don't be shy about triggering a remote blank even if you just suspect your device is missing. You can always recover your data if you find your device.

Several service providers offer hosted Exchange Servers for a small monthly fee. Call to make sure that the provider offers either Exchange Server 2003 with mobile extensions or Exchange Server 2007, and ask whether users are allowed access to Exchange Server's management console. Without management console access, you can't remotely blank your phone.

Apple designed the iPhone as a consumer device, so it's heavy on convenience and light on security. If you want protection, you have to accept some pain. Fortunately, it doesn't take a lot of time or tech savvy to keep what's in your iPhone for your eyes only. The oft-repeated recommendations alluded to in the beginning of this story are all worthwhile, but if you augment them creatively, you'll befuddle the bad guys with techniques they hadn't considered and that don't yield to automated cracks. Never overlook unorthodoxy as a means of protection.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

Windows 10 for Business / Dell XPS 13

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Windows 10 / Lenovo Yoga 910

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
