LOGON/AUTOLOG/LINK Journaling Option LOGON/AUTOLOG/LINK journaling is a system generation option that records
all unsuccessful LOGON attempts and all LINK attempts using different
Fossible passwords. LINK journaling records all linking (successful and
unsuccessful) including directory links to protected minidisks --those
whose password for the type link being attempted is anything except ALL. LOGON/AUTOLOG/LINK journaling is provided by generation of new types
of accounting records (types 04, 05, and 06). These record types are
generated whenever a user reaches an installation defined threshold of
invalid passwords in attempting to issue LOGON/AUTCLOG and LINK co.mands. Additionally, an installation defined userid is notified when
a second threshold is reached. Accounting routines that expect only
previously defined record types and fail if they encounter any other
type, will also fail if the journaling option is chosen since the
accounting records generated are new.
This option modifies the current mechanism that limits invalid LOGON/AUTOLOG and LINK commands to a fixed value tefore disabling those co.mands. LOGON/AUTOLOG and LINK commands are disabled when an
installation defined threshold now specified via the new SYSJRL macro
instruction is reached and journaling is set on. Messages generated when the threshold for consecutive incorrect LOGON/AUTOLOG and LINK passwords has been reached or exceeded are sent
to the userid specified in the SYSJRL macro instruction. The system administrator is also notified of unsuccessful uses of the LOGON and
LINK commands.
The new JOURNAL operand has been added to the CP QUERY and SET co •• ands to reflect support of LOGON/AUTOLOG/LINK journaling. The QUERY JOURNAL command is used to question the status of the journaling option
while the SET JOURNAL command turns LOGON/AUTOLOG/LINK journaling on cr
off.
To support the LOGON/AUTOLOG/LINK journaling option, two additional
control blocks are added: PWDIBLOK (Passwcrd Invalid Block) JPSCBLOK (Journaling and Password Suppression Control Block)
