I am CISM (Qualified) Now!!!

I had appeared for CISM (Certified Information Security Manager) on 8th June, 2013 in Kuwait.

Alhamdulillah (All Praises are for Allah [Glorified be He]), I was able to pass the exam, since I was not able to prepare as I had done at the time of CISA preparation.

Just as CISA exam demands you think like an Auditor when answering the CISA questions, CISM too demands you answer the CISM questions as an Information Security Manager would. It is more of a "Management" perspective of Security.

My current organization's ISMS (Information Security Management System) Implementation (i.e. ISO 27001) and me being a part of the core implementation team, really helped me a lot in answering the CISM exam.

[Re-post from Jaffar's Oracle blog] Deprecated database init. parameters in 12c

Deprecated database init. parameters in 12c

"Here is a very short blog about all the deprecated database initialization parameters in 12c.  It is sometime becomes essential to be familiar with those database features and init. parameters that are either de-supported or deprecated in a new release of Oracle database before proceeding with the upgrade. This is because, some of the legacy applications upgrade decision either directly or in-directly depends on those changes.

To obtain a list of deprecated database parameter in 12c, use the following SQL statement:

SQL> SELECT name from v$parameter WHERE isdeprecated = 'TRUE' ORDER BY name;
Here is the list:
I am little bit surprised to see the sec_case_sensitive_logon parameter in the list."

Oracle Database: To z/OS or To z/Linux? That is the Question!!!

Oracle has been supporting Oracle Databases on z/OS since version 8.

"Experiences with Oracle Database 10g on z/OS", is a good IBM Publication that describes experiences with the installation process of Oracle 10g on z/OS.

"Oracle® Database Installation Guide 10g Release 1 (10.1) for IBM z/OS (OS/390)" from Oracle is a detailed documentation on the subject.

The last supported Oracle Database on IBM z/OS operating system was Oracle Database 10g. Unfortunately, those with this combination of implementation will not benefit from the latest features and benefits of Oracle Database 11g R2 on z/OS.

My Oracle Support (formerly Metalink): Note 461234.1 Oracle Database on z/OS Support Status

The possible options for people with Oracle Database 10g on z/OS, is:
  1. Either, shift to a different RDBMS Database on z/OS (continuing on existing hardware investments);
  2. Or, continue with Oracle Database onto a different Operating System (possible investments in additional Hardware Environments).
Fortunately, IBM offers its "Linux on System z" as a possible alternative to run the Oracle Databases; and Oracle too supports its latest Oracle Database release on z/Linux.

This means that Oracle customers have an option to stick with the latest updates on Oracle Database and leverage their existing hardware investments, by switching on to Linux on System z (a.k.a. z/Linux) on Mainframes as their operating system.

The 10g migration from z/OS to z/Linux must be thoroughly tested. And once found satisfactory and stable, it can be upgraded to latest release of Oracle Database on z/Linux.

For more information on 11gR2 on z/Linux:

Toad World PIPELINE Newsletter (Sept '11 Issue) has my Third Technical Paper

The September 2011 Edition of Toad World PIPELINE Newsletter has published my third Oracle Technical Paper titled "How to resolve Root Certificate Expiry Issue for Enterprise Manager - Database Control".

In it I have tried to explain how to resolve the Oracle Enterprise Manager – Database Control configuration errors for Oracle Database versions or, as a result of the expired Root Certificate since 31st December, 2010.

I had written the paper in June 2011, after encountering and resolving the issue at my end. Not much has been written on this in detail, apart from the My Oracle Support. So I thought it will be a good idea to jot it down for others to benefit.

Click on the hyperlink to read the Toad World PIPELINE Newsletter (September '11 Issue):

I hope it is a nice read and means to a quick resolution.

Zaffer Khan, CISA

Got my CISA Certification today and now I am CISA Certified.

I had applied for Certification for CISA in March '11. And now I am a Certified Information Systems Auditor, as opposed to being Qualified based on passing the exam. The minimum benefit of this is that my name can have CISA appended to it. What more can I derive, is yet to come in my way as I progress in career. :)

To certify, I needed to show 5+ years of experience in Information Systems Security, Control or Audit. Obviously, I don't have any Auditing experience, but I applied based on Security and Control Experience. Got 1 year waiver for IT Experience and 2 years waiver due to my Bachelor and Master Degrees. So in all, I had to show only 2+ years of Information Systems Security, Control or Audit.
It took less than 2 months for the confirmation of certification. This is a great achievement, All Praises to God.
Thanks a lot for your well-wishes and support, especially Mr. Narendra Tater and Mr. Srinivas Dokku. I am indebted for your assistance.

I am CISA (Qualified) now

I had appeared for CISA (Certified Information Systems Auditor) on 11th December, 2010 in Kuwait.

Because of the amount of efforts put in for this examination, I have been anxiously waiting for the results. When I saw the email from ISACA in my inbox.... all I can say is my heartbeats were quite higher than normal... Adrenaline was doing its job. When I saw "PASSED" in the message body... there was a quick change of emotions.... Really felt the switch happening...
Going from Fear, through a mix of emotions to a big smile on my face.... Alhamdulillah (All Praises are for Allah [Glorified be He]).

The exam was difficult and it tested my CISA skills to the extreme. Never prepared so hard for any exam till date... Really felt that Oracle Certifications are piece of cake in front CISA examination. Was tough.... You really need to think like an auditor. It was difficult for me to think from an "Asessing" point-of-view as I have been studying, thinking and doing things from "Doing" point-of-view. Even when I worked on IT Governance and Balance Scorecard in my present company ()using COBIT 4.0), it was from a "Doing" perspective. Only when I was with the IS Auditors, I would try to understand how they do their work.

From a DBA's standpoint, I can see a lot of my work that needs improvement using the knowledge acquired by CISA contents. Personally, I need to audit my own work now, so as to suggest myself in areas of improvement (as observations) or to raise an NCR (Non-Compliance Report) for myself. This should help me self-assess my work and be proactive with preventive actions.

For more information about ISACA and CISA (and also a variety of certifications) please hop into ISACA's website:

For now, I look forward to certify my CISA soon.

Next in the queue should be CISSP, I think?
