Today, several proprietary radios enable key and less entry and proximity sensor capabilities to unlock car doors or start the ignition. But because these links are not based on standards, each accessory must be compatible with the specific proprietary technology or it will not work. Wireless in-vehicle that include Bluetooth Low Energy (LE) capabilities, however, enable interoperability with all in-vehicle wireless systems, allowing consumers to use any of their mobile accessories to open car doors or start the ignition. The advent of the Bluetooth LE specification represents a paradigm shift in efficiency, enabling dramatically increased battery life for Bluetooth products.

However, once the first bank became a victim, immediately all the other institutions started to learn more about the attacks, search for solutions, then deploy those solutions quickly. When I look at military cloud security solutions, there are many vendors and partners providing tools and solutions, but not many providing availability security embedded computer attacks are hurting the availability of online services and many antivirus vendors and firewall vendors do not focus on the availability aspect.” Cloud providers find protecting the shared infrastructure can be challenging because it is an expensive up-front cost, he continues.
