Description

4 credit/unit hours – Four hours of lecture weekly; one term

This course introduces the learner to the fundamentals of securing wireless networks. Students focus on creating and implementing an organization’s enforceable security policies by following applicable regulations, standards, and accepted effective practices. Students also identify and mitigate threats to the wireless network. Lastly, learners use various tools and procedures to ensure the ongoing security of the network.

This course also helps prepare students for the Certified Wireless Security Professional (CWSP) certification exam (CWSP-206).
