Online network monitoring. [PDF]

open access: yesStat Methods Appt, 2021
AbstractAn important problem in network analysis is the online detection of anomalous behaviour. In this paper, we introduce a network surveillance method bringing together network modelling and statistical process control. Our approach is to apply multivariate control charts based on exponential smoothing and cumulative sums in order to monitor ...

Woody species response to altered herbivore pressure at Isle Royale National Park

open access: yesEcosphere, 2023
Herbivores shape vegetative communities via numerous mechanisms, including browse. We used vegetation monitoring data from Isle Royale National Park to examine woody species change across a nine‐year interval, coinciding with herbivore escalation.

A network security monitor [PDF]

open access: yesProceedings. 1990 IEEE Computer Society Symposium on Research in Security and Privacy, 1990
This study concentrates on the security-related issues in a single broadcast LAN (local area network) such as Ethernet. The authors formalize various possible network attacks. Their basic strategy is to develop profiles of usage of network resources and then compare current usage patterns with the historical profile to determine possible security ...
