• The audit trail, which consists of several audit devices and tables that you
determine at configuration time
• The syslogs transaction log device, which stores transaction logs
The sybsecurity
device and database
The sybsecurity device stores the sybsecurity database. The sybsecurity
database is created as part of the auditing configuration process. It contains all
the system tables in the
model database, as well as a system table for keeping
track of server-wide auditing options and system tables for the audit trail.
Tables and devices for
the audit trail
Adaptive Server stores the audit trail in system tables, named sysaudits_01
through
sysaudits_08. At any given time, only one of the audit tables is current.
Adaptive Server writes all audit data to the current audit table. A System
Security Officer can use
sp_configure to set or change which audit table is
current.
When you configure Adaptive Server for auditing, you determine the number
of audit tables for your installation. You can specify up to eight system tables
(
sysaudits_01 through sysaudits_08). Plan to use at least two or three system
tables for the audit trail and to put each system table on its own device, separate
from the master device. If you do this, you can use a threshold procedure that
archives the current audit table automatically, before it fills up and switches to
a new, empty table for subsequent audit records.
Device for syslogs
systems table
During auditing configuration, you must specify a separate device for the
syslogs system table, which contains the transaction log. The syslogs table,
which exists in every database, contains a log of transactions that are executed
in the database.
Overview of audit installation
There are two methods for installing auditing for the first time in Adaptive
Server:
•Use the
installsecurity script. For information, see the System
Administration Guide.
•Use the
auditinit utility. Tasks that you must perform before installing
auditing and instructions on using the
auditinit utility follow.
