  • Insider attacks pose an often neglected threat scenario when devising security mechanisms for emerging wireless technologies. For example, traffic safety applications in vehicular networks aim to prevent fatal collisions and preemptively warn drivers of hazards along their path, thus preserving numerous lives. Unmitigated attacks upon these networks stand to severely jeopardize their adoption and limit the scope of their deployment.

  • Hello, in this module we are going to discuss wireless networking. Specifically, we'll take a look at how wireless technology works, how it is commonly deployed, and the security issues associated with using it. Because wireless communications can penetrate opaque objects such as buildings, the risk of someone accessing a private network increases markedly. With wireless, an attacker does not need to gain access to physical cables or jacks, but only needs to have an antenna and be within range of the transmissions....
