AI-suggested

1. 2. Restrict network access to MySQL Cluster instances by implementing strict firewall rules and network segmentation, allowing only trusted hosts and services to communicate with the database cluster. 3. Disable or limit exposure of unnecessary protocols and services that provide network access to MySQL Cluster to reduce the attack surface. 4. Monitor MySQL Cluster logs and system resource usage for abnormal patterns indicative of attempted resource exhaustion or crashes. 5. Implement rate limiting and connection throttling at network and application layers to mitigate potential DoS attempts. 6. Conduct regular security assessments and vulnerability scans to identify and remediate exposure of MySQL Cluster instances. 7. Employ intrusion detection/prevention systems (IDS/IPS) tuned to detect unusual traffic patterns targeting database services. 8. Maintain an incident response plan that includes procedures for handling database service outages and recovery.
