Crunchy Data PostgreSQL Security Technical Implementation Guide

Rules, Groups, and Values defined within the XCCDF Benchmark

  • PostgreSQL must record time stamps, in audit records and application data that can be mapped to Coordinated Universal Time (UTC, formerly GMT).

    If time stamps are not consistently applied and there is no common time reference, it is difficult to perform forensic analysis. Time stamps generated by PostgreSQL must include date and time. Tim...
    Rule Medium Severity
  • PostgreSQL must allow only the Information System Security Manager (ISSM), or individuals or roles appointed by the ISSM, to select which auditable events are to be audited.

    Without the capability to restrict which roles and individuals can select which events are audited, unauthorized personnel may be able to prevent or interfere with the auditing of critical events. ...
    Rule Medium Severity
  • PostgreSQL must provide an immediate alert to appropriate support staff of all audit log failures.

    It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required. Without a real-time alert, security personnel may be unaware of an impe...
    Rule Medium Severity
  • PostgreSQL must by default shut down upon audit failure, to include the unavailability of space for more audit log records; or must be configurable to shut down upon audit failure.

    It is critical that when PostgreSQL is at risk of failing to process audit logs as required, it take action to mitigate the failure. Audit processing failures include software/hardware errors; fail...
    Rule Medium Severity
  • PostgreSQL must maintain the confidentiality and integrity of information during reception.

    Information can be either unintentionally or maliciously disclosed or modified during reception, including, for example, during aggregation, at protocol transformation points, and during packing/un...
