  The emerging trend of ubiquitous and pervasive computing aims at embedding
everyday devices such as wristwatches, smart phones, home video systems,
autofocus cameras, intelligent vehicles, musical instruments, kitchen
appliances etc. with microprocessors and imparts them with wireless
communication capability. This advanced computing paradigm, also known as the
Internet of Things or cyber-physical computing, leads internet and computing to
appear everywhere and anywhere using any device and location. With maximum
appreciation and due regards to the evolutionary arc, depth and scope of
ceaseless internet utilities, it is equally necessary to envisage the security
and data confidentiality challenges posed by the free and ubiquitous
availability of internet. This paper analyses the role of computational
intelligence techniques to design adaptive and cognitive intrusion detection
systems that can efficiently detect malicious network activities and proposes
novel three-tier architecture for designing intelligent intrusion detection
systems for wireless networks.
