In today's world people are extensively using internet and thus are also vulnerable to its flaws. Cyber security is the main area where these flaws are exploited. Intrusion is one way to exploit the internet for search of valuable information that may cause devastating damage, which can be personal or on a large scale. Thus Intrusion detection systems are placed for timely detection of such intrusion and alert the user about the same. Intrusion Detection using hybrid classification technique consist of a hybrid model i.e. misuse detection model (AdTree based) and Anomaly model (svm based).NSL-KDD intrusion detection dataset plays a vital role in calibrating intrusion detection system and is extensively used by the researchers working in the field of intrusion detection. This paper presents Association rule mining technique for IDS. General TermsIntrusion Detection System, Preprocessing, Security et. al.

In order to account for the role that hospitals play in health policy, this research paper will useand build customized health policy theory. The way in which health services are provided is heavilyinfluenced by health policies. Due to its inflexible structure and misguiding policies, it is a well-knownissue with the purchase of health insurance. Due to this, the appropriate resources are not allocated at theappropriate time, which results in reimbursement failure, health burden, and financial losses as a result oferror in judgement or misunderstanding. Therefore, personalizing health policies to meet the requirementsof specific people or groups is possible. The framework for making decisions to improve people's healthstatus is known as health policy. The significance and problems with developing health policies arediscussed in detail in this paper, along with methodological concerns. Methodological concerns are cited,and the majority of the works in this field are cited. After introducing the subject and outlining the need forhealth policy, it is explained from several academic perspectives and what a health policy is. The stages ofthe cycle for developing policies are discussed. The health policy development cycle is described in thisreview paper, along with the methodological concerns it raises. The study places further emphasis onevidence-based health policy and then describes the lessons that may be drawn from prior attempts atdeveloping policy. The report finishes by outlining the difficulties in creating and implementing a successfulhealth strategy.

Wireless sensor networks (WSNs) consist of sensor nodes. It is a collection of wild number of low cost device constraint sensor nodes that communicates using wireless medium and they are small in size, low battery power and limited processing capability. This restraint of low electricity power of a sensor node and limited energy capability makes the wireless sensor network failure. A data aggregation is very important techniques in wireless sensor networks and it reduces the energy consumption by eliminating redundancy. In WSNs, Sensor nodes are resources constrained in memory, data sensing, and battery power and communication capability. Data communication is the process of communications between nodes that consumes a large portion of the total amount of energy used up for WSNs. One of the solutions to reduce number of bits transmitted during communication is data aggregation. As wireless sensor networks are usually deployed in remote and hostile environments to trajectory sensitive information or data, sensor nodes are affected by attacks. Thus, security is an important issue to be considered in WSNs.
