This alert triggers when there are more than 3 failed connection attempts to the RDS MariaDB database in a 5-minute interval for a specific user. Impact Multiple failed connection/login attempts in a short time frame might indicate a brute-force attack against the relevant account. Mitigation Check if the user is aware of the connection attempts and that these are legit. If not, investigate it further. Additionally, administrators can consider the following recommendations to better secure MariaDB: 1. Require all MariaDB accounts to have a strong password. 2. Do not run MariaDB with root-level privileges. 3. If the MariaDB database is only used by local applications, remote access to the server should be disabled. 4. The MariaDB instance should be configured to only allow access to permitted hosts. MITRE Tactic: TA0006 MITRE Technique: T1110
