Greetings!
Here is your iSeries security tip for October, 2006
from SkyView
Partners, Inc., World Class i5/OS
and OS/400 Security Experts.
I have been asked the same question – How do I get
information out of the i5/OS audit journal? – twice
within the last week! So I thought that some of you
may be wondering the same thing. The answer?
There are two methods you can use. #1 - Run the
DSPAUDJRNE command. The default is to look for the
AF - or authority failure entries. The result is only a
subset of the information from the AF audit journal
entries. However, there is often enough information
to determine what has caused a particular entry to
be generated.
However, if you want more of
the information that's in the audit journal entry or if
you see *N as the object name (indicating that the
object is in the IFS), then you must dump the audit
journal entries to an outfile and query the results.
To do that, create a duplicate of the model outfile
for the audit journal entry type
CRTDUPOBJ OBJ(QASYxxJ5) FROMLIB(QSYS) OBJTYPE
(*FILE) TOLIB(QTEMP) where xx is the audit journal
entry type you're looking for - in your case of an
authority failure, it would be "AF".
Then
display the audit journal to an outfile
DSPJRN JRN(QAUDJRN) FROMTIME('09/25/06') JRNCDE
((T)) ENTTYP(xx) +
OUTPUT(*OUTFILE) OUTFILFMT(*TYPE5) OUTFILE
(QTEMP/QASYxxJ5)
Now you can either
display the file or query the results (my preferred
method) and see all fields in the audit journal. V5R4
provides a command, CPYAUDJRNE which combines
the create duplicate object and display journal into
one command. The audit journal model outfiles are
described in Appendix F of the iSeries Security
Reference manual, available from the IBM Information
Center.

Policy Minder Tip - Discover “new” items.
Starting your Christmas list?
You might want to add a 30-
day free trial of the newest version of SkyView Policy
Minder to your list!
Policy Minder
version
1.2
offers some significant time-saving enhancements
including:
Create
templates to discover “new” items.
Using one of the new features of Policy Minder 1.2,
many administrators are creating templates to
discover “new” items on their systems. For example,
to discover when a new library has been created on
the system, they create a library template, include
all libraries and set the “Allow new libraries” attribute
to be *NO. Any new library created after taking an
initial baseline check will be identified. Now you can
discover the libraries created by installing vendor
software, programmers creating duplicate libraries to
test with, etc.
Administrators are using the “Allow new xxx”
template attribute to manage many aspects of their
system. Here are a few more examples:
- Creating a template for the
objects in QGPL
to discover what programmers are placing in the
library.
- Creating a template for all user
profiles
having *ALLOBJ special authority to discover any
new powerful profiles that get created or changed to
change *ALLOBJ.
- Creating a template for the root
(‘/’)
directory to discover newly created directories.
- Identifying new items and cross-
referencing
these with their HA system to ensure their HA
replication process is working as they expect.
- When migrating to a new system,
creating
user profile and object templates to identify new
objects being created on the existing system so that
they can also be created on the new system until
the cut-over occurs.

Are you overwhelmed with the details of managing
your security policy compliance requirements? Let
SkyView Policy Minder automate that process. IBM
thought enough of SkyView products to certify them
as ‘Server Proven” and as “i5/OS ready”.
