This is particularly the case for individuals who are access unsecured networks such as in public spaces, airports and even in hotels. Cyber-security is an important issue to understand and to ensure the safety of your personal information and finances.

The TSA is in the process of improving its wireless network security following an audit by the Department of Homeland Security (DHS) which covered cybersecurity on devices like Blackberries. The audit examined how well sensitive information was protected on TSA networks, and it revealed that the physical and logical network access controls employed by TSA were effective in avoiding major vulnerabilities.

However, they found weaknesses and vulnerabilities related to patches and configuration controls which needed to be improved. The DHS made some specific recommendations to TSA in this regard, including the importance of revising the patch management process update patches in a more timely way and to enforce security policy on all TSA employes to ensure that every individual had their devices and systems properly secured. TSA has made considerable progress in securing their local area networks since 2007.

If you need to receive alerts about certain aspects related to your work or your personal life, then finding the best apps that accomplish this for you is one of the most convenient benefits of having a Smartphone. This way, you're not tied to your computer. Since there can be a multitude of apps available, it's good to make your own top top 10 app list to choose from. This you can do by looking at other such lists that experts have published. Cross-referencing a few of them is a good way to narrow down what apps seem to stand out. Still, since these apps need to suit your purposes, if you don't see something that seems best for you, keep looking. I know I actually wasn't completely convinced about a very popular app, and when I looked a little further, I was so pleased to find something just right for me. Nonetheless, I find that it's always good to start with published lists to get an idea of what's out there, what's the latest, and what stands the test of time. It may take a bit of doing, but in the end, the convenience of having just the right apps on your Smartphone will be worth the research.

Google is committed to near field communications (NFC) as the company sees it playing a major role in mobile marketing trends going forward.

The company recently rolled out Google Wallet and Google Offers which are both based on NFC technology, and these initiatives were the highlight of the latest NFC Payments Europe conference in London. While many of the bankers and mobile operators in attendance praised the interoperability and openness of the company's offerings, they also had some criticisms and concerns. Some were worried that Google didn't fully grasp the complexities of the payment eco system, while others were concerned that they were really just after more customer purchasing data. Still others are worried that Google will simply dominate the electronic payments market as they have done in other areas.
