Security Challenges of Wireless Communications Networks: A Survey (original) (raw)

Despite the gains offered by wireless communications networks, such as portability, flexibility, increased productivity, roaming capabilities, cheap installation costs, and many more, the security of wireless networks has continued to be of great challenge and concern. Currently, wireless communications vulnerabilities are on the increase due to the higher demand for higher data rates, the need for advanced services and that of roaming, and the huge deployment of services across the globe. Consequently, this has created serious challenging issues in the security of wireless systems and applications in wireless environments. Incidentally, wireless networks and handheld devices are exposed to the same level of vulnerabilities and risks with that of conventional wired networks. However, nowadays, the risks and threats associated with wireless networks have taken a new dimension, ostensibly because the communication medium, the airwave, of wireless networks is openly exposed to intruder...
