Detailed Description

Real-time security monitoring and alerting.

Note

This class uses dependency injection pattern. Access via database_context::get_security_monitor() (Sprint 3, Task 3.3).

Example:

auto context = std::make_shared<database_context>();
auto sec_monitor = context->get_security_monitor();
