Vulnerability discussion

Failure to a known state can address safety or security in accordance with the mission/business needs of the organization.Failure to a known secure state helps prevent a loss of confidentiality, integrity, or availability in the event of a failure of the information system or a component of the system. Preserving information system state information helps to facilitate system restart and return to the operational mode of the organization with less disruption of mission/business processes. Since it is usually not possible to test this capability in a production environment, systems should either be validated in a testing environment or prior to installation. This requirement is usually a function of the design of the IDPS component. Compliance can be verified by acceptance/validation processes or vendor attestation.

Check content

At the command prompt, execute the following command: # /opt/vmware/vpostgres/current/bin/psql -U postgres -c "SELECT name, setting FROM pg_settings WHERE name IN ('fsync','full_page_writes','synchronous_commit');" If "fsync", "full_page_writes", and "synchronous_commit" are not set to "on", this is a finding. The command should return the below lines: name | setting ---------------------------+--------- fsync | on full_page_writes | on synchronous_commit | on (3 rows)

Fix text

At the command prompt, execute the following commands: # /opt/vmware/vpostgres/current/bin/psql -U postgres -c "ALTER SYSTEM SET TO 'on';" # /opt/vmware/vpostgres/current/bin/psql -U postgres -c "SELECT pg_reload_conf();" Note: Substitute with the incorrectly set parameter.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
