Due to the complexity of the social network server system, various system abnormalities may occur and in turn will lead to subsequent system failures and information losses. Thus, to monitor the system state and detect the system abnormalities are of great importance. As the system log contains valuable information and records the system operating status and users’ behaviors, log data in system abnormality detection and diagnosis can ensure system availability and reliability. This paper discloses a log analysis method based on deep learning for an intrusion detection system, which includes the following steps: preprocess the acquired logs of different types in the target system; perform log analysis on the preprocessed logs using a clustering-based method; then, encode the parsed log events into digital feature vectors; use LSTM-based neural network and log collect-based clustering methods to learn the encoded logs to form warning information; lastly, trace the source of the warning information to the corresponding component to determine the point of intrusion. The paper finally implements the proposed intrusion detection method in the server system, thereby improving the system’s security status.

Cyber-attacks on the Internet of Things (IoT) are growing at an alarming rate as devices, applications, and communication networks are becoming increasingly connected and integrated. When attacks on IoT networks go undetected for longer periods, it affects availability of critical systems for end users, increases the number of data breaches and identity theft, drives up the costs and impacts the revenue. It is imperative to detect attacks on IoT systems in near real time to provide effective security and defense. In this paper, we develop an intelligent intrusion-detection system tailored to the IoT environment. Specifically, we use a deep-learning algorithm to detect malicious traffic in IoT networks. The detection solution provides security as a service and facilitates interoperability between various network communication protocols used in IoT. We evaluate our proposed detection framework using both real-network traces for providing a proof of concept, and using simulation for providing evidence of its scalability. Our experimental results confirm that the proposed intrusion-detection system can detect real-world intrusions effectively.

Cyber security threats are an ever increasing, frequent and complex issue in the modern information era. With the advent of big data, incremental increase of huge amounts of data has further increased the security problems. Intrusion Detection Systems (IDS) were been developed to monitor and secure the cyber data systems and networks from any intrusions. However, the intrusion detection is difficult due to the rapid evolution of security attacks and the high volume, variety and speed of big data. In addition, the shallow architectures of existing IDS models lead to high computation cost and high memory requirements, thus further diminishing the efficiency of intrusion detection. The recent studies have suggested the use of data analytics and the deep learning algorithms can be effective in improving the IDS. An efficient IDS model is developed in this study by using the improved Elman-type Recurrent Neural Networks (RNN) in which the Improved Chicken Swarm Optimization (ICSO) optimally determines RNN parameters. RNN is an efficient method for classifying network traffic data but its traditional training algorithms are slow in convergence and faces local optimum problem. The introduction of ICSO with enhanced global search ability significantly avoids those limitations and improves the training process of RNN. This optimized deep learning algorithm of RNN, named as ICSO-RNN, is employed in the IDS with Intuitionistic Fuzzy Mutual Information feature selection to analyze larger network traffic datasets. The proposed IDS model using ICSO-RNN is tested on UNSW NB15 dataset. The final outcomes suggested that ICSO-RNN model has high performance in intrusion detection, with minimum training time and is proficient for big data

Security in IoT networks is currently mandatory, due to the high amount of data that has to be handled. These systems are vulnerable to several cybersecurity attacks, which are increasing in number and sophistication. Due to this reason, new intrusion detection techniques have to be developed, being as accurate as possible for these scenarios. Intrusion detection systems based on machine learning algorithms have already shown a high performance in terms of accuracy. This research proposes the study and evaluation of several preprocessing techniques based on traffic categorization for a machine learning neural network algorithm. This research uses for its evaluation two benchmark datasets, namely UGR16 and the UNSW-NB15, and one of the most used datasets, KDD99. The preprocessing techniques were evaluated in accordance with scalar and normalization functions. All of these preprocessing models were applied through different sets of characteristics based on a categorization composed by four groups of features: basic connection features, content characteristics, statistical characteristics and finally, a group which is composed by traffic-based features and connection direction-based traffic characteristics. The objective of this research is to evaluate this categorization by using various data preprocessing techniques to obtain the most accurate model. Our proposal shows that, by applying the categorization of network traffic and several preprocessing techniques, the accuracy can be enhanced by up to 45%. The preprocessing of a specific group of characteristics allows for greater accuracy, allowing the machine learning algorithm to correctly classify these parameters related to possible attacks.
