Adding auditing

Adaptive Server Enterprise

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.
