A Sparse Bayesian Framework for Anomaly Detection in Heterogeneous Networks

The capability to detect anomalous states in a network is important for both the smooth operation of the network and the security of the network. Modern networks are often heterogeneous. This raises a new challenge for anomaly detection, as there may be a wide variety of anomalous activities across the heterogeneous components of a network. We often seek a detection system that not only perform...

Anomaly detection in online social networks

Anomalies in online social networks can signify irregular, and often illegal behaviour. Detection of such anomalies has been used to identify malicious individuals, including spammers, sexual predators, and online fraudsters. In this paper we survey existing computational techniques for detecting anomalies in online social networks. We characterise anomalies as being either static or dynamic, a...

A Survey on Anomaly Detection Methods for Ad Hoc Networks

Mobile ad hoc networks have recently been the topic of extensive research. The interest in such networks stems from their ability to provide temporary and instant wireless networking solutions in situations where cellular infrastructures are lacking and are expensive or infeasible to deploy. Despite their desirable characteristics, vital problems concerning their security must be solved in orde...

Machine Learning Methods for Anomaly Detection in BACnet Networks

In recent years, the volume and the complexity of data in Building Automation System networks have increased exponentially. As a result, a manual analysis of network traffic data has become nearly impossible. Even automated but supervised methods are problematic in practice since the large amount of data makes manual labeling, required to train the algorithms to differentiate between normal tra...
