Your Database Exposure Risk | UpGuard

This article explains database management systems (relational and NoSQL), highlights the security risks of exposing database services on default open ports, and lists common ports for technologies like MySQL, PostgreSQL, MongoDB, Redis, Elasticsearch, Kafka, Cassandra, and more. It emphasizes reducing external attack surface through internal-only access, VPNs, access controls, encryption, patching, auditing, and firewall rules, and describes how UpGuard’s continuous, non-intrusive scanning can identify publicly exposed database services and inform remediation.
