Among the classes of data mining techniques, anomaly-based intrusion detection plays a central role in the discovery of new attacks such as zero-day attacks and multi-step attacks: it encompasses both information and knowledge layers.
Then, the state-of-the-art techniques of anomaly detection in WSNs are systematically introduced, according to WSNs' architectures (Hierarchical/Flat) and detection technique categories (statistical techniques, rule based, data mining, computational intelligence, game theory, graph based, and hybrid, etc).
Some core technologies are needed to solve the problem in big data, such as effective data collection and storage and data mining techniques and anomaly detection method.
In this study, a data mining approach using a machine learning technique called anomaly detection (AD) is presented.
Other techniques include anomaly-based detection, which flag any anomalous behaviour as an attack.
Nonetheless, if we consider the analysis of events in a central location, as we do in this paper, the most widespread technique is anomaly detection through the clustering of network data [52 54], in some cases combined with supervised methods such as SVM [55].
Instantaneous calcification rates (alkalinity anomaly techniques) were also highly variable between individuals, and did not significantly differ (coralliths: −0.97 to 1.70 µmol CaCO3 cm−2 h−1; static controls: −0.08 to 1.54 µmol CaCO3 CaCO3h−1).
Traditional intrusion detection systems based on signature and anomaly techniques are no longer sufficient to protect SGs due to their new connectivity and management challenges, the ever-rapidly-evolving masquerades, and cyber criminality levied against them.
Validation of the alkalinity anomaly technique for investigating calcification of photosynthesis in coral reef communities.
The growing hierarchical self organizing map (GHSOM) has been shown to be an effective technique to facilitate anomaly detection.
There was no corresponding change in calcification rates between treatments, measured using the alkalinity anomaly technique and 14C uptake.
