SRG-APP-000359-DB-000319
Group -
DB2 must provide a warning to appropriate support staff when allocated audit record storage volume reaches 75% of maximum audit record storage capacity.
Organizations are required to use a central log management system, so, under normal conditions, the audit space allocated to the DBMS on its own server will not be an issue. However, space will sti...Rule Medium Severity -
SRG-APP-000360-DB-000320
Group -
DB2 must provide an immediate real-time alert to appropriate support staff of all audit failure events requiring real-time alerts.
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 -
SRG-APP-000378-DB-000365
Group -
DB2 must prohibit user installation of logic modules (stored procedures, functions, triggers, views, etc.) without explicit privileged status.
Allowing regular users to install software, without explicit privileges, creates the risk that untested or potentially malicious software will be installed on the system. Explicit privileges (escal...Rule Medium Severity -
SRG-APP-000380-DB-000360
Group -
DB2 and the operating system must enforce access restrictions associated with changes to the configuration of DB2 or database(s).
Failure to provide logical access restrictions associated with changes to configuration may have significant effects on the overall security of the system. When dealing with access restrictions p...Rule Medium Severity -
SRG-APP-000381-DB-000361
Group -
DB2 must produce audit records of its enforcement of access restrictions associated with changes to the configuration of DB2 or database(s).
Without auditing the enforcement of access restrictions against changes to configuration, it would be difficult to identify attempted attacks and an audit trail would not be available for forensic ...Rule Medium Severity -
SRG-APP-000383-DB-000364
Group -
DB2 must disable network functions, ports, protocols, and services deemed by the organization to be nonsecure, in accord with the Ports, Protocols, and Services Management (PPSM) guidance.
Use of nonsecure network functions, ports, protocols, and services exposes the system to avoidable threats.Rule Medium Severity -
SRG-APP-000427-DB-000385
Group -
DB2 must only accept end entity certificates issued by DoD PKI or DoD-approved PKI Certification Authorities (CAs) for the establishment of all encrypted sessions.
Only DoD-approved external PKIs have been evaluated to ensure that they have security controls and identity vetting procedures in place which are sufficient for DoD systems to rely on the identity ...Rule Medium Severity -
SRG-APP-000428-DB-000386
Group -
DB2 must implement cryptographic mechanisms to prevent unauthorized modification of organization-defined information at rest (to include, at a minimum, PII and classified information) on organization-defined information system components.
DBMSs handling data requiring "data at rest" protections must employ cryptographic mechanisms to prevent unauthorized disclosure and modification of the information at rest. These cryptographic mec...Rule Medium Severity -

When invalid inputs are received, DB2 must behave in a predictable and documented manner that reflects organizational and system objectives.
A common vulnerability is unplanned behavior when invalid inputs are received. This requirement guards against adverse or unintended system behavior caused by invalid inputs, where information syst...Rule Medium Severity -

Group -
Security-relevant software updates to DB2 must be installed within the time period directed by an authoritative source (e.g. IAVM, CTOs, DTMs, and STIGs).
Security flaws with software applications, including database management systems, are discovered daily. Vendors are constantly updating and patching their products to address newly discovered secur...Rule High Severity -

The content of the drawer really is up to you. It could have form fields, definition lists, text lists, labels, charts, progress bars, etc. Spacing recommendation is 24px margins. You can put tabs in here, and can also make the drawer scrollable.
