PostgreSQL must limit the number of concurrent sessions to an organization-defined number per user for all accounts and/or account types.
Database management includes the ability to control the number of users and user sessions using PostgreSQL. Unlimited concurrent connections to PostgreSQL could allow a successful denial-of-service...Rule Medium Severity -
PostgreSQL must protect against a user falsely repudiating having performed organization-defined actions.
Nonrepudiation of actions taken is required to maintain data integrity. Examples of particular actions taken by individuals include creating information, sending a message, approving information (e...Rule Medium Severity -
PostgreSQL must produce audit records containing sufficient information to establish what type of events occurred.
Information system auditing capability is critical for accurate forensic analysis. Without establishing what type of event occurred, it would be difficult to establish, correlate, and investigate t...Rule Medium Severity -
PostgreSQL must produce audit records containing sufficient information to establish the sources (origins) of the events.
Information system auditing capability is critical for accurate forensic analysis. Without establishing the source of the event, it is impossible to establish, correlate, and investigate the events...Rule Medium Severity -
PostgreSQL must produce audit records containing sufficient information to establish the outcome (success or failure) of the events.
Information system auditing capability is critical for accurate forensic analysis. Without information about the outcome of events, security personnel cannot make an accurate assessment as to wheth...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 the DBMS 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; failur...Rule Medium Severity -
The audit information produced by PostgreSQL must be protected from unauthorized read access.
If audit data were to become compromised, then competent forensic analysis and discovery of the true source of potentially malicious system activity is difficult, if not impossible, to achieve. In ...Rule Medium Severity -
PostgreSQL must protect its audit configuration from unauthorized modification.
Protecting audit data also includes identifying and protecting the tools used to view and manipulate log data. Therefore, protecting audit tools is necessary to prevent unauthorized operation on au...Rule Medium Severity -
The PostgreSQL software installation account must be restricted to authorized users.
When dealing with change control issues, it should be noted any changes to the hardware, software, and/or firmware components of the information system and/or application can have significant effec...Rule High Severity
