O.AUDITS
O. AUDITS is the objective that provides the function to record auditable
events and its log data.
By satisfying the following security requirements, O.AUDITS can be
realized.
By FAU_GEN.1, the security audit log data are generated for the
auditable events: (However, audit is unnecessary for the following
functional requirements for each reason described below.)
- FAU_STG.4: The total number of security audit log data events is
fixed. The data are stored and updated automatically.
- FCS_CKM.1: When cryptographic key generation fails, a system error
occurs at the time of booting of the MFD.
- FSC_COP.1: An encryption failure is monitored as job status.
- FDP_IFF.1: The flow is fixed. No event is to be monitored.
- FMT_MSA.3: No change is to be applied to default values and rules.
By FAU_SAR.1, the authorized system administrator can read the
security audit log data from an audit log file.
By FAU_SAR.2, only the authorized system administrator can access the
security audit log data.
By FAU_STG.1, the security audit log data stored in an audit log file is
protected from unauthorized deletion and alteration.
By FAU_STG.4, when the security audit log data is full, the oldest stored
audit record is overwritten and a new audit event is stored into the audit
