A firewall typically operates at the network layer, inspecting traffic for known patterns and rules, but it may not be able to understand the context of the data being transmitted within SQL queries. SQL Injection attacks exploit vulnerabilities in application code, allowing attackers to manipulate database queries through user inputs rather than directly attacking the network. Firewalls can filter out known malicious signatures but may not detect sophisticated or unique SQL injection attempts. Moreover, if the application itself is flawed, the firewall cannot compensate for those vulnerabilities.
