host-based detection
In this presentation, we will discuss our progress in developing techniques for host-based anomaly detection. We will show our approach for combining system call models and other system events namely file operations for better accuracy. We will also discuss how the learning and building time of reference models can be significantly reduced using varying length n-grams. This is contrasted with fixed n-gram techniques used in the literature. We will discuss questions of model generalization and the reduction of false-positive rates.  Another aspect of this presentation will focus on the detection of rootkits using techniques inspired by reverse engineering research,  hence putting engineering into rootkit detection research. Preliminary results will be shown followed with future steps.

10:30 11:00 Francis Giraldeau /Pr. Michel Dagenais Distributed traces modelling and critical path analysis The dependencies between the different events causing state changes in processes are automatically analyzed in order to compute the critical path between a start and end event (e.g. query and response). This analysis takes into account several effects including parallel computations happening asynchronously and many different models of distributed computations. This is extremely helpful in identifying where the total time is spent to serve a request.

LTTng-Tmf-hack Day, December 12 from 9h30

Meeting room:  L-4812  Bring your laptop or your whole desktop!

Informal hacking/tutorial on LTTng and Trace Compass.  Come with your questions and projects and we'll all work on it together, or in small groups.  Depending on the demand, some more formal sessions may be scheduled for those interested.  We have the room all day.
