Specifies the access criteria that cause an audit message to
    be written to the system security audit log file. A message is
    recorded by default. A message is recorded only if ACL audits are
    enabled with the DCL command SET AUDIT/AUDIT/ENABLE=ACL.

1  –  Parameters

 options

    Specify one of the following attributes:

    Default      Indicates that an ACE is to be included in the
                 ACL of any files created within a directory. When
                 the entry is propagated, the Default attribute
                 is removed from the ACE of the created file. This
                 attribute is valid for directory files only.
    Hidden       Indicates that this ACE should be changed only by
                 the application that adds it. Although the Hidden
                 attribute is valid for any ACE type, its intended
                 use is to hide Application ACEs. To delete or modify
                 a hidden ACE, you must use the SET SECURITY command.

                 Users need the SECURITY privilege to display a
                 hidden ACE with the DCL commands SHOW SECURITY
                 or DIRECTORY/SECURITY. SECURITY privilege is also
                 required to modify or delete a hidden ACE with the
                 DCL command SET SECURITY. The ACL editor displays
                 the ACE only to show its relative position within
                 the ACL, not to facilitate editing of the ACE. To
                 create a hidden ACE, an application can invoke the
                 $SET_SECURITY system service.
    Protected    Protects the ACE against casual deletion. Protected
                 ACEs can be deleted only in the following ways:

                 o  By using the ACL editor

                 o  By specifying the ACE explicitly when deleting it

                    Use the command SET SECURITY/ACL=(ace)/DELETE to
                    specify and delete an ACE.

                 o  By deleting all ACEs, both protected and
                    unprotected

                    Use the command SET SECURITY/ACL/DELETE=ALL to
                    delete all ACEs.

                 The following commands do not delete protected ACEs:

                    SET SECURITY/ACL/DELETE
                    SET SECURITY/LIKE
                    SET SECURITY/DEFAULT

    Nopropagate  Indicates that the ACE cannot be copied by
                 operations that usually propagate ACEs. For example,
                 the ACE cannot be copied by the SET SECURITY/LIKE or
                 SET SECURITY/DEFAULT commands.
    None         Indicates that no attributes apply to an entry.
                 Although you can create an ACL entry with
                 OPTIONS=None, the attribute is not displayed.
                 Whenever you specify additional attributes with
                 the None attribute, the other attributes take
                 precedence. The None attribute is equivalent to
                 omitting the field.

 access

    Specify any access that is valid for the object class. See the
    OpenVMS Guide to System Security for a listing of valid access
    types. For an Audit ACE to have any effect, you must include the
    keywords SUCCESS, FAILURE, or both with the access types. For
    example, if the auditing criterion is a failure to obtain write
    access to an object, specify the following Audit ACE:

    (AUDIT=SECURITY,ACCESS=WRITE+FAILURE)
