How do the C++ backend and the web interface interact?

The interaction model is as follows:

C++ backend:

• manages Suricata;
• receives events;
• writes data to Redis;
• exposes REST endpoints.

Web interface:

• works directly with the REST API;
• reads aggregated data from the backend;
• does not interact with C++ directly.

C++ is used where the following are critical:

• performance;
• low latency;
• operation on low-end hardware.
