With President Obama highlighting the national importance of cyber security, we turn to technology specialist Gregg Early to find the best investment ideas in the sector.

Noting that "cyber security is one of the biggest new sectors in the information technology industry," the editor of Personal Finance offers a trio of buys in the field -- McAfee (NYSE: MFE), Versar (AMEX: VSR), and Unisys (NYSE: UIS).

The advisor explains, "In exchange for an annual fee, McAfee allows users to download the basic security software and regular updates. These frequent updates are essential because virus and malware threats are constantly evolving.

One of the best things about living in a fast changing technology world is that we are constantly given smaller, stronger, and typically better ways to enjoy our music and videos. The downside is that often the new technology makes part of our media library go extinct.

For many of us, the shelves upon shelves of VHS tapes we accumulated in the 80's are now sitting in a closet somewhere collecting dust and just waiting to get thrown away. A new device from Sony (NYSE: SNE) is hoping to change that and bring these ancient relics back to life.

Sony presents the DVDirect VRD-MC3 which could save the lives of millions of VHS recordings. This new device promises to make transferring VHS recordings to DVD a fast and simple solution for millions of people that just can't seem to bring themselves to throw away their vast VHS collection.

The best thing about this device is that it operates as a stand alone product and there is no need to use a computer to convert your VHS tapes. This is a big plus for all the people out there (myself included) who would be lost trying to figure out how to connect my old VCR to my laptop and transfer and edit my tapes to DVD format.

The product also works to create DVD's from newer digital cameras as well as files stored on your computer.

And at a little over $200 it is an affordable solution to saving all those decaying VHS tapes you have stashed away!
