Correctly labelled dataseis are commonly required. Three particular scenarios are highlighted, which showcase this need. One of these scenarios is when using supervised Intrusion Detection Systems (TDSs). These systems need labelled datasets for their training process. Also, the real nature of analysed datasets must be known when evaluating the efficiency of IDSs detecting intrusions. The third scenario is the use of feature selection that works only if the processed datasets are labelled. In normal conditions, collecting labelled datasets from real communication networks is impossible. In a previous work we developed a novel approach to automatically generate labelled network traffic datasets using an unsupervised anomaly based IDS. The approach was empirically proven to be an efficient unsupervised labelling approach. It was evaluated using a single dataset. This paper extends our previous work by using a greater number of datasets, gathered from a real IEEE 802.11 network testbed. The datasets are comprised of different wireless-specific attacks. This paper also proposes a new and more precise method to calculate the boundary threshold, used in the labelling process.
