Week Goals: Initialize HMMs with clustering to provide a good guess at beginning states and probabilities. Focus into DDoS data set to create a tiered system of HMMs to predict different attacks and subattacks better
Wednesday: Presented our weekly presentation at the group discussion, began working on a plan for the tiered HMM system. Looked into using clustering to initialize HMMs
Thursday:Successfully used K medoids clustering to initialize our HMMs and coded a tiered HMM process in Matlab to detect attacks, with each attack having its own set of features used to detect it and separate HMMs for each possible attack.
Friday: Began testing with the new tiered system. Worked on our last weekly presentation for the group meeting next Tuesday. Met with Coach, Aziz, and Ali over the presentation, what changes to make to it, and what we can still accomplish with the last two weeks of the REU program.
