It's something I cannot stress enough: privacy and security issues are one of the most pressuring fields in technology. This topic will increase with more and more wearable products and technologies.

Good to have this report at home where ZDnet writes a complete overview of security risks and answers for mobile networks. Thats something everyone in the business should know. Most of all as user worldwide mostly don't have a clue what "information sharing" in networks can mean..

Some of the security concerns are:
• Rogue users
• Inadequate access policies and procedures
• Unauthorized access to bandwidth via public hotspots
• Stolen laptops and other wireless-enabled devices
• Poorly guarded access ports

But better you read the whole thing:
