Guardium STAP for IBM i
Both QAUDJRN and SQL information is streamed to the Guardium collector

Global SQL Monitor using a view and instead of trigger captures SQL information and
puts them on a Unix queue
•
Audit server job
– Runs in batch
– Receives QAUDJRN audit entries and puts them on a Unix queue
– Runs a Guardium AIX executable in PASE to receive entries from the queue and
send them to the collector
– On an IPL we will restart automatically (you may have to start the subsystem)

Filtering Which Data to Capture
There are several places where audit data is filtered:
• Normal auditing controls filter what data goes into QSYS/QAUDJRN
• Filtering only specific Journal Entry Types can be configured
• Only certain journal entry types are processed and sent to Guardium
• Only certain attributes of the journal entries are processed and sent to Guardium
• The database monitor can filter data
• The same filtering available on STRDBMON can be configured
• Only certain monitor entries are processed and sent to Guardium
• Only certain attributes of the monitor entries are captured and sent to Guardium
• The Guardium collector can perform additional filtering via Policies.
For example:
• Only capture security failures
• Only capture failures for certain users or objects
• Etc. Etc. Etc.

Monitor Entry Type Filtering
Some of the entries are strictly of interest for isolating performance and response time problems.
These entries are omitted: (not sent to the Guardium appliance)
CH CLOSE (Hard)
HC CLOSE (Hard)
HH CLOSE (Hard)
JR Recycle Prestart Job
PD PREPARE DESCRIBE (except authorization errors are captured)
PR PREPARE (except authorization errors are captured)

Some of the DBMON entries are not useful from an audit standpoint.
These entries are omitted: (not sent to the Guardium appliance)
AD ALLOCATE DESCRIPTOR
HL HOLD LOCATOR
CL CLOSE
RE RELEASE
DA DEALLOCATE DESCRIPTOR
RG RESIGNAL
FE FETCH
SC SET CONNECTION
FL FREE LOCATOR
SD SET DESCRIPTOR
GD GET DIAGNOSTICS
SG SIGNAL
GS GET DESCRIPTOR
Xx Entries (-primarily X/Open)
Some statements are sub-statements of another statement, these are also omitted: (not sent)
IN INSERT that is part of a CREATE TABLE or DECLARE GLOBAL TEMPORARY TABLE AS ... WITH DATA
DL DELETE that is part of a MERGE
IN INSERT that is part of a MERGE
UP UPDATE that is part of a MERGE
10

QAUDJRN Filtering
The audit entries that we capture can be controlled by configuring which entry types should be captured.
By default, the following are returned:
ZR Read object
ZC Change object
CA Authority change
CP Change Profile
AD Auditing change
AF Authority failure
CO Create object
DO Delete object
GR General purpose audit record
OM Object moved or renamed
PG Primary group change
PW Invalid password or user ID
OW Change owner
OR Object restored
RA Restore authority change
RO Restore owner change
RZ Restore primary group change
SV System Value change
Note: CD Command string is supported, but not by default
Since the focus is primarily on database changes, we will only return entries related to objects that are database specific:
*FILE (a table, view, index, logical file, alias, or device file)
*SQLUDT (an SQL user-defined type)
*SQLPKG (an SQL package)
*PGM (a procedure, function, or program)
*SRVPGM (a procedure, function, global variable, or service program)
*DTAARA (an SQL sequence)
For entries that identify an object, the statement text part of the message will be constructed as follows:
XX - 30-byte-text 10-byte-library 10-byte-object-name 8-byte-object-type
For example:
ZC - Change object

Audit Server Status information
STATUS_TIME
Timestamp of this request for status
SERVER_STARTED
Indicates whether the server is currently started or not (YES or NO)
START_TIME
Timestamp of the last time the server was started
SERVER_JOB
Job name of the server
NUMBER_JOBS_AUDITED_USING_SQL
Number of jobs that have processed an SQL statements since the server was started
NUMBER_PROCESSED_SQL_STATEMENTS
Number of SQL statements that have been processed since the server was started. This does not include SQL
statements filtered out by STRDBMON
NUMBER_ENQUEUED_SQL_STATEMENTS
Number of SQL statements that have been enqueued since the server was started. This does not include SQL statements
filtered out.
NUMBER_SKIPPED_SQL_STATEMENTS
Each job will attempt to put an SQL statement on the queue up to three times. This indicates that some number of
SQL statements could not be audited. Rare…typically indicates a queue problem.
NUMBER_PROCESSED_VARIABLE_SETS
Number of SQL statements that have variables since the server was started. Some SQL statements have variables and some
not. This does not include SQL statements filtered out.
NUMBER_SKIPPED_VARIABLE_SETS
Number of SQL statements whose variable values were discarded. Since the variable values are written to the
monitor PRIOR to the actual SQL statement, It is possible that several sets of variables will have to be saved until
the SQL statement shows up. Up to 300 sets of variables are saved so this is extremely unlikely.
NUMBER_PROCESSED_QAUDJRN_ENTRIES
Number of journal audit entries that have been processed since the server was started. This does not include audit entries
filtered out.
NUMBER_ENQUEUED_QAUDJRN_ENTRIES
Number of journal audit entries that have been enqueued since the server was started. This does not include
entries filtered out.
NUMBER_SKIPPED_QAUDJRN_ENTRIES
Number of journal audit entries that were discarded. This indicates that some number of audit journal entries could
not be audited. Rare…typically indicates a queue problem.
QUEUE_DAMAGED
Indicates whether or not the queue is damaged. (YES or NO)
NUMBER_MESSAGES_ON_QUEUE
Number of messages currently on the queue
SIZE_OF_MESSAGES_ON_QUEUE
Size of the queue
MAXIMUM_SIZE_OF_QUEUE
Maximum size of the queue (this is always 16 meg)
TOTAL_ENQUEUING_THREADS
Total number of threads enqueuing messages
LAST_DEQUEUE_TIME
Timestamp of the last dequeue operation
LAST_ENQUEUE_TIME
Timestamp of the last enqueue operation
QUEUE_OWNER
Owner of the queue. This is the user that started the server
LAST_END_MONITOR_JOB
Job of the user that last ended the monitor
LAST_END_MONITOR_USER
User that last ended the monitor

Best Practices
•
•
•
•
Capture only what you need by using filtering
Filtering at the IBM i is better than filtering at the Guardium collector
Create a new user profile and a unique job description for the audit server batch job
Create a unique group profile and use it to audit your highly privileged users

Alert On Failed Login (Exception Rule)
APPUSER is

account
Exception Type
= Failed Login
Min Count =

Reset Interval =

Action = Alert
So… Alert on 3

Contrasting DB2 for i - Data Security
DB2 for i Data Security options go well beyond the data model.
Open Database File (QIBM_QDB_OPEN) exit program is called when a
when a job is opening a database file. Use this interface to deploy blocking
and more.
Query Governor protects against over consumption of CPU or Storage
http://www-01.ibm.com/support/knowledgecenter/api/content/ssw_ibm_i_72/apis/xqrygovr.htm
IBM i Function usage IDs provide a granular role based security
authorization (allow or deny) based upon users or groups.
https://www.ibm.com/developerworks/community/wikis/home?lang=es#!/wiki/IBM%20i%20Technology%20Updates/p
age/DB2%20for%20i%20Security%20Enhancements
IBM i has exit programs for connection interfaces and commands. The exit
program can block or log or more.

Field Procedures and Data Encryption
Create a CUSTOMER table where the CCNBR column has a FIELDPROC.
Allows for transparent
encryption or
encoding/decoding of data
on SQL or native interfaces
CREATE TABLE CUSTOMER (
NAME VARCHAR(50),
ADDRESS VARCHAR(100),
CCNBR CHAR(16) FIELDPROC ENCRYPTLIB.ENCRYPTPGM1 )
Alter an existing CUSTOMER table to add a FIELDPROC to the CCNBR column.
ALTER TABLE CUSTOMER
ALTER COLUMN CCNBR SET FIELDPROC ENCRYPTLIB.ENCRYPTPGM1
