Introduction In spite of the many developments in network security over the past decade, the Internet remains a hostile environment for our networked computer systems.
Jumping emerging patterns JEPs for a test instance are minimal patterns that match the test instance but they do not match any normal instances. OCLEP was based on the observation that one needs long JEPs to differentiate an instance of one class from instances of the same class, but needs short JEPs to differentiate an instance of one class from instances of a different class.

Wireless networks have become increasingly more heterogeneous. Secure and collab- orative operation of mobile wireless ad-hoc networks poses significant challenges due to the decentralized nature of mobile ad hoc wireless networks, mobility of nodes, and re- source constraints.
Recent developments in software defined networking shed new light on how to control and manage an ad hoc wireless network. Given the wide deployment and availability of heterogeneous wireless technologies, the control and management of ad hoc wireless networks with the new software defined networking paradigm is offered more flexibility and opportunities to deal with trust and security issues and to enable new features and services.
Specifically, I We have proposed four design options for software defined secure collaborative ad hoc wireless network architecture.
The de- sign options are organized into a centralized SDN controller architecture with controller replication and b distributed SDN controller architecture. While these proposed architec- ture options exhibit different characteristics, many common challenges are shared amongst these options.
Challenges include fault-tolerance, scalability, efficiency, and security. The unstructured nature of ad hoc wireless networks exacerbates these challenges.
We have studied the pros and cons of these different design options and their applicability in differ- ent practical scenarios via simulations. II Establishing the initial trust among participating devices in an SDN based wireless mobile ad hoc network will serve as a basis for enabling ensuing secure communication of the network.

Computer Engineering; Computer Science Keywords: Anomaly-based intrusion detection systems detect attacks by analyzing either computer or network data and flagging abnormalities as intrusions.
The abnormalities are detected by analyzing certain parameters that are present in the data. Our approach analyzes certain network parameters, which characterize either a connection or a network service on a monitored host or a network service on a monitored network.
This categorization of parameters helps detect varied classes of attacks including denial-of-service, port scan and buffer overflow attacks. Anomaly-based systems use various analysis techniques to detect parameter anomalies. A new approach based on Bayesian Networks technique for analyzing and detecting anomalies is presented here.
The advantage of Bayesian Networks lies in their ability to adaptively learn normal values of parameters without much training, which makes it suitable for real-time analysis. Bayesian Network can be used to combine current evidence and previous knowledge to obtain the probability of anomaly.
This property helps in detecting previously seen attacks faster, since the previous knowledge provides strong evidence of an attack. The same property helps reduce the number of false positives, since considerable evidence needs to accumulate for the Bayesian Network to report high probability of anomaly.Computational Intelligence in Intrusion Detection System Thesis Submitted to Department of Mathematics, Faculty of Science, Al-Azhar iii.
