This paper introduces novel attack detection approaches on mobile and wireless device security and network which consider temporal relations between internet packets. In this paper we first present a field selection technique using a Genetic Algorithm and generate a Packet-based Mining Association Rule from an original Mining Association Rule for Support Vector Machine in mobile and wireless network environment. Through the preprocessing with PMAR SVM inputs can account for time variation between packets in mobile and wireless network. Third we present Gaussian observation Hidden Markov Model to exploit the hidden relationships between packets based on
