Goal
Detect database connections from IP addresses that are identified as malicious. Network access to database servers should be restricted.
Strategy
This rule monitors logs from PostgreSQL to detect when a connection originates from an IP identified as malicious. Datadog enriches all ingested logs with threat intelligence in real time.
A High signal is generated if the connection resulted in a successful login. A Low signal is generated if there was no login attempt or the login attempt failed.
Triage and response
- Determine if the user
{{ @db.user }} is expected to authenticate from the IP {{ @network.client.ip }}. - Restrict network access to the database. Remove any public access.
- If the login was successful review database logs for suspicious actions taken by the user
{{ @db.user }}. - Rotate credentials for the affected account.
