$AUDIT_EVENT

Appends an event message to the system security audit log file or sends an alarm to a security operator terminal.

Format

SYS$AUDIT_EVENT [efn] ,[flags] ,itmlst ,[audsts] ,[astadr] ,[astprm]

C Prototype

int sys$audit_event (unsigned int efn, unsigned int flags, void *itmlst, unsigned int *audsts, void (*astadr)(__unknown_params), int astprm);

Arguments

efn

OpenVMS usage: ef_number

type: longword (unsigned)

access: read only

mechanism: by value

Number of the event flag to be set when the audit completes. The efn argument is a longword containing the number of the event flag; however, $AUDIT_EVENT uses only the low-order byte. If efn is not specified, event flag 0 is used.
Upon request initiation, $AUDIT_EVENT clears the specified event flag.
flags

OpenVMS usage: mask_longword

type: longword (unsigned)

access: read only

mechanism: by value

Flags specifying options for the $AUDIT_EVENT system operation. The flags argument is a longword bit mask, where each bit corresponds to an option.
Each flag option has a symbolic name. The $NSADEF macro defines the following symbolic names.

Symbolic Name Description

NSA$M_ACL Specifies an event generated by an Alarm ACE or Audit ACE. This flag is reserved to Compaq.

NSA$M_FLUSH Specifies that all messages in the audit server buffer be written to the audit log file.

NSA$M_INTERNAL Specifies that the $AUDIT_EVENT call originates in the context of a trusted computing base (TCB) component. The auditing components use this flag to indicate that internal auditing failures should result in a SECAUDTCB bugcheck. This flag is reserved to Compaq.

NSA$M_MANDATORY Specifies that an audit is to be performed, regardless of system alarm and audit settings.

NSA$M_NOEVTCHECK Specifies that an audit is to be performed, regardless of the system alarm or audit settings. This flag is similar to the NSA$M_MANDATORY bit but, unlike the NSA$M_MANDATORY bit, this flag is not reflected in the NSA$W_FLAGS field in the resulting audit record on disk.

NSA$M_SERVER Indicates that the call originates in a TCB server process and that the event should be audited regardless of the state of a process-specific, no-audit bit.
Trusted servers use this flag to override the no-audit bit when they want to perform explicit auditing on behalf of a client process. This flag is reserved to Compaq.

itmlst

OpenVMS usage: item_list_3

type: longword (unsigned)

access: read only

mechanism: by reference

Item list specifying information to include in the audit record. The itmlst argument is the address of a list of item descriptors. The list of item descriptors is terminated by a longword of 0.
The item list for all calls to $AUDIT_EVENT must include the following item codes:

NSA$_EVENT_TYPE (see Table SYS-2)
NSA$_EVENT_SUBTYPE (see Table SYS-2)
At least one of the NSA$_ALARM_NAME item code or the NSA$_AUDIT_NAME item code.
If the event being reported is an object access (NSA$C_MSG_OBJ_ACCESS) or an object delete (NSA$C_MSG_OBJ_DELETE), the NSA$_FINAL_STATUS, NSA$_ACCESS_DESIRED, and NSA$_OBJECT_CLASS item codes must be specified.
If the event being reported is an object create (NSA$C_MSG_OBJ_CREATE), the NSA$_FINAL_STATUS and NSA$_OBJECT_CLASS item codes must be specified.
If the event being reported is a privilege audit (NSA$C_MSG_PRVAUD), the NSA$_PRIVS_USED or the NSA$_PRIVS_MISSING item code must be specified.
If the audit event being reported is a deaccess event (NSA$C_MSG_OBJ_DEACCESS), the NSA$_OBJECT_CLASS item code must be specified.

The item list is a standard format item list. The following diagram depicts the general structure of an item descriptor.

Symbolic Name	Description
NSA$M_ACL	Specifies an event generated by an Alarm ACE or Audit ACE. This flag is reserved to Compaq.
NSA$M_FLUSH	Specifies that all messages in the audit server buffer be written to the audit log file.
NSA$M_INTERNAL	Specifies that the $AUDIT_EVENT call originates in the context of a trusted computing base (TCB) component. The auditing components use this flag to indicate that internal auditing failures should result in a SECAUDTCB bugcheck. This flag is reserved to Compaq.
NSA$M_MANDATORY	Specifies that an audit is to be performed, regardless of system alarm and audit settings.
NSA$M_NOEVTCHECK	Specifies that an audit is to be performed, regardless of the system alarm or audit settings. This flag is similar to the NSA$M_MANDATORY bit but, unlike the NSA$M_MANDATORY bit, this flag is not reflected in the NSA$W_FLAGS field in the resulting audit record on disk.
NSA$M_SERVER	Indicates that the call originates in a TCB server process and that the event should be audited regardless of the state of a process-specific, no-audit bit. Trusted servers use this flag to override the no-audit bit when they want to perform explicit auditing on behalf of a client process. This flag is reserved to Compaq.

The following table defines the item descriptor fields.

Descriptor Field Definition

Buffer length A word specifying the length (in bytes) of the buffer; the buffer supplies information to be used by $AUDIT_EVENT. The required length of the buffer varies, depending on the item code specified; each item code description specifies the required length.

Item code A word containing a symbolic code describing the nature of the information currently in the buffer. The location of the buffer is pointed to by the buffer address field. Each item code has a symbolic name. This section provides a detailed description of item codes following the description of arguments.

Buffer address A longword containing the address of the buffer that specifies the information.

Return length address Not currently used; this field is reserved to Compaq. You must specify 0.

See the Item Codes section for a description of the $AUDIT_EVENT item codes.

audsts

OpenVMS usage:	cond_value_type
type:	longword (unsigned)
access:	write only
mechanism:	by reference

Longword condition value that receives the final completion status from the operation. If a security audit is required, the final completion status represents either the successful completion of the resulting security audit or any failing status that occurred while the security audit was performed within the audit server process.

The audsts argument is valid only when the service returns success and the status is not SS$_EVTNOTENAB. In addition, the caller must either make use of the astadr argument or use the $AUDIT_EVENTW service before attempting to access audsts.

astadr

OpenVMS usage:	ast_procedure
type:	procedure value
access:	call without stack unwinding
mechanism:	by reference

Asynchronous system trap (AST) routine to be executed after the audsts is updated. The astadr argument, which is the address of a longword value, is the procedure value of the AST routine.

The AST routine executes in the access mode of the caller of $AUDIT_EVENT.

astprm

OpenVMS usage:	user_arg
type:	longword (unsigned)
access:	read only
mechanism:	by value

Asynchronous system trap (AST) parameter passed to the AST service routine. The astprm argument is a longword value containing the AST parameter. Item Codes This section provides a list of item codes that can be used to affect auditing.

NSA$_ALARM_NAME
NSA$_ALARM_NAME is a string of 1 to 32 characters specifying an alarm journal name to receive the record. To direct an event to the system alarm journal (that is, all enabled security operator terminals), use the string SECURITY.
NSA$_AUDIT_NAME
NSA$_AUDIT_NAME is a string of 1 to 65 characters specifying the journal file to receive the audit record. To direct an event to the system audit journal, use the string SECURITY.
NSA$_CHAIN
NSA$_CHAIN is a longword value specifying the item list to process immediately after the current one. The buffer address field in the item descriptor specifies the address of the next item list to be processed. Anything after NSA$_CHAIN is ignored.
NSA$_EVENT_FACILITY
NSA$_EVENT_FACILITY is a word value specifying the facility generating the event. All operating system events are audited as facility zero.
NSA$_EVENT_SUBTYPE
NSA$_EVENT_SUBTYPE is a longword value specifying an event message subtype. See Table SYS-2 for a list of valid event subtypes.
NSA$_EVENT_TYPE
NSA$_EVENT_TYPE is a longword value specifying an event message type. See Table SYS-2 for a list of valid event types.

NSA$_FIELD_NAME
NSA$_FIELD_NAME is a string of 1 to 256 characters specifying the name of the field being modified. This is used in combination with NSA$_ORIGINAL_DATA and NSA$_NEW_DATA.
NSA$_MESSAGE
NSA$_MESSAGE specifies a system message code. The $FORMAT_AUDIT service will use the $GETMSG service to translate the message into text. The resulting text is inserted into the formatted audit message, with the "Event information:" prefix. For example, the operating system uses this item code to supply the privilege audit text associated with privilege audit events; this keeps the audit records small. By default, the $GETMSG service can only translate resident system messages. You can use the NSA$_MSGFILNAM item code to specify the name of an application or site-specific message file.
NSA$_MSGFILNAM
NSA$_MSGFILNAM is a string of 1 to 255 characters specifying the message file containing the translation for the message code in NSA$_MESSAGE. The default file specification is SYS$MESSAGE:.EXE. By default, $FORMAT_AUDIT uses the resident system message file.
NSA$_NEW_DATA
NSA$_NEW_DATA is a string of 1 to n characters specifying the contents of the field named in NSA$_FIELD_NAME after the event occurred. NSA$_ORIGINAL_DATA contains the field contents prior to the event.
NSA$_NOP
NSA$_NOP specifies that the item list entry should be ignored. This item code allows you to build a static item list and then remove those entries that do not apply to the current event.
NSA$_ORIGINAL_DATA
NSA$_ORIGINAL_DATA is a string of 1 to n characters specifying the contents of the field named in NSA$_FIELD_NAME before the event occurred. NSA$_NEW_DATA contains the field contents following the event.
NSA$_SENSITIVE_FIELD_NAME
NSA$_SENSITIVE_FIELD_NAME is a string of 1 to 256 characters specifying the name of the field being modified. This is used in combination with NSA$_SENSITIVE_ORIG_DATA and NSA$_SENSITIVE_NEW_DATA. Use NSA$_SENSITIVE_FIELD_NAME to prevent sensitive information, such as passwords, from being displayed in an alarm message. Sensitive information is written to the audit log.
NSA$_SENSITIVE_NEW_DATA
NSA$_SENSITIVE_NEW_DATA is a string of 1 to n characters specifying the contents of the field named in NSA$_SENSITIVE_FIELD_NAME after the event occurred. NSA$_SENSITIVE_ORIG_DATA contains the field contents prior to the event. Use NSA$_SENSITIVE_NEW_DATA to prevent sensitive information from being displayed in an alarm message. Sensitive information is written to the audit log.
NSA$_SENSITIVE_ORIG_DATA
NSA$_SENSITIVE_ORIG_DATA is a string of 1 to n characters specifying the contents of the field named in NSA$_SENSITIVE_FIELD_NAME before the event occurred. NSA$_SENSITIVE_NEW_DATA contains the field contents following the event. Use NSA$_SENSITIVE_FIELD_NAME to prevent sensitive information from being displayed in an alarm message. Sensitive information is written to the audit log.
NSA$_SUPPRESS
NSA$_SUPPRESS is a longword bitmask directing $AUDIT_EVENT to ignore the defaults for the following values and either omit the information from the event record or use the value provided in another parameter. The bits in the mask inhibit the use of default values for the following item codes:

NSA$V_ACCOUNT_NAME NAS$V_PROCESS_NAME

NSA$V_FINAL_STATUS NSA$V_SUBJECT_CLASS

NSA$V_IMAGE_NAME NSA$V_SUBJECT_OWNER

NSA$V_PARENT_ID NSA$V_SYSTEM_ID

NSA$V_PARENT_NAME NSA$V_SYSTEM_OWNER

NSA$V_PARENT_OWNER NSA$V_TERMINAL

NSA$V_PARENT_USERNAME NSA$V_TIME_STAMP

NSA$V_PROCESS_ID NSA$V_USERNAME

Use NSA$_SUPPRESS, for example, when auditing events from server processes when the default values for many of these items need to explicitly reference the client context rather than be defaulted from the environment of the server.

Description

The Audit Event service can be called by any program that enforces a security policy to append an event message to the audit log file or send an alarm to an operator terminal. For example, AUTHORIZE calls $AUDIT_EVENT whenever a UAF record is altered, and LOGINOUT calls the service whenever a user logs in.
