PostgreSQL Credentials

Description

General

• Documentation: https://www.postgresql.org/docs/13/index.html
• Summary: PostgreSQL is an open-source relational database management system. This detector catches PostgreSQL credentials in the form of a URI connection string, in a CLI command or stored in a pgpass file.
• IPs allowlist: IPs allowlisting can be enforced on the server side.
• Scopes: PostgreSQL supports a role-based access, and thus different level of access can be granted to different users.

Revoke the secret

A variety of PostgreSQL commands are useful to change a user's role, password or even to drop the concerned user. This documentation page can be a good starting point to get more information on the topics.

Check for suspicious activity

Auditing PostgreSQL logs can provide information about any suspicious activity on the database.
