Self-protection against business logic vulnerabilities

Attacks against business logic rules occur when the attacker exploits the domain rules in a malicious way. Such attacks have not received sufficient attention in research so far. In this paper, we propose a novel self-protecting approach that defends a system against the exploitation of business logic vulnerabilities. The approach empowers a system with a self-protecting layer to protect it against attacks aimed at misusing business logic rules. The approach maintains up-to-date domain knowledge which is analyzed using runtime verification to detect logical attacks. When attacks are discovered they are dynamically mitigated by applying proper system reconfigurations at runtime. We evaluate the approach using a case from the domain of hotel booking systems.
