I’m Ali Yousefi, a final-year BSc Computer Science student at City St George’s, University of London.

My dissertation project, AegisRAG, studies how word-substitution attacks poison the knowledge base of a cybersecurity question-answering system (retrieval-augmented generation), and how to detect and defend against them, using relative entropy and a runtime verification monitor. It is supervised by Dr Hafizul Asad, with the relative-entropy approach suggested by Dr Nikos Komninos.

This blog is my public log of that project and of my wider cybersecurity learning.
