Steps to perform comprehensive IT Audit
Let\’s talk about IT Audit in todays world. What have you heard about IT Audit now? Have you ever been involved in such audits? I have been working for a Big 4 company for almost 5 years and all always I was performing different types of IT Audit. Thus, I think that I have some IT Audit experience.
Most of my audits were targeted to financial audits, which is the main operations of my firm. However, we had performed separate IT Audits and IT Security Audits for different companies across CIS region.
While doing such small IT audits during work for financial team, you often hear such term as IT Risk Assessment. We need to remember about risks in all our work, thus it is nothing to do – but we need to determine how our clients perform IT risk assessments at their systems. That is why we always look at various reports about work performed, talk to different employees from IT department – our target is to confirm that this particular company has dialed with IT risk and no significant impact would arise to the company business operations. We just need to find any possible risks to our work, as our final report will be very important. It would be not very good, if in future this conclusion will be impacted by exploitation of some risk, which we had not seen during our work.
But in order to perform good and quality IT Audit we need to use various IT Audit Tools and techniques. Such tools are different for different environments – for example for Windows environment it would be some tools provided by Microsoft company (e.g. MS Security Base Line Analyzer). And for UNIX environment we would use another tools. The same is with databases – one IT Audit tools will be used for Oracle databases and another will be used for MS SQL databases. But always while performing IT Audit assessment you need to use different IT Audit Tools. This will significantly reduce the amount of manual work you need to accomplish.
Thus, by doing IT Audit assessments, we need to remember about IT Risk Assessment, which may be made by company itself, or we may perform such assessment. We need also to use some IT Audit tools and technics, and produce appropriate report for our analysis. And only after all these tasks are finished, we can start making our IT Audit Report. This is very hard work, as you need to consider all findings which came to your attention during the IT Audit work. You need to combine all these findings, sort them, and decide on which of them will go to final report. Usually, this is done through classification of findings based on their criticality and impact to the business operations of the company. You can classify all findings as having Low, Medium or High impact. Usually we report only Medium and High findings to the executives of the company. And the Low findings are reported only to local IT management in order to address the risk.
