Topic for master's thesis

Question

SQL

A friend asked me to post a question. So the next problem is that we need an interesting topic for a master's work on SQL injection or web application security in general. Moreover, the use of some kind of mathematics in research is required. Please let me know if there are options.

Answer 1

1. Genetic algorithm for generating SQL-inject/XSS.
2. Algebra of logics and proof of invulnerability to specific types of attacks.
3. Probability theory and the best way to find vulnerabilities.
PS I didn't really think about it, but I think each of the topics can be developed to a master's.

Answer 2

Attack trees? If you combine with injections - it will be ok, you can use a lot of graph theory
