There have been various security measures that deal with data security in wired or wireless network, where these measures help to make sure that data from one point to another is intact, by identifying, authenticating, authorizing the right users and also encrypting the data over the network. Data communication between computers has brought about countless benefits to users, but the same information technologies have created a gap, a vulnerable space in the communication medium, where the data that’s been exchanged or transferred, thereby causing threats to the data. Especially data on wireless networks are much exposed to threats since the network has been broadcasted unlike a wired network. Data security in the past dealth with integrity, confidentiality and ensuring authorized usage of the data and the system. Less or no focus was placed on the reactive approach or measures to data security which is capable of responding properly to mitigate an attacker and avoid harm and also to prevent future attacks. This research is going to expose the mechanisms and measures of data security in wireless networks from the reactive security approaches point of view and exposes the reactive approaches used to enhance data security.
