Suricata high number of requests detected from single IP address
Set up the suricata integration.
Goal
Detect an unusually high number of requests are made from a single IP address, which could indicate a potential brute force attack, Denial-of-Service (DoS) attempt, or other malicious activities aimed at overwhelming or exploiting the server.
Strategy
Monitor Suricata logs where a single IP address generates a high number of requests within a short period. This detection rule aims to identify potential threats early, allowing for timely investigation and mitigation to protect server resources and maintain service availability.
Triage and response
- Analyse the pattern and volume of requests to distinguish between legitimate traffic and potential attacks.
- Investigate the source IP
{{@network.client.ip}} address to determine if the activity is malicious. - Implement immediate measures to block or limit the impact of the suspicious activity if confirmed as a threat.
