Steps to conduct comprehensive IT Audit
Let\’s talk about IT Audit in todays world. What do you know about IT Audit now? Have you ever performed such audits? I have been working for a Auditing company for almost 5 years and all this time 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 business of my company. However, we had performed separate IT Audits and IT Security Audits for various companies worldwide.
While performing such small IT audits during work for financial audit, you often hear such term as IT Risk Assessment. We need to consider 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 IT environments. That is why we always look at various reports about work performed, talk to different employees from IT department – our target is to ensure 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 affected by exploitation of some risk, which we had not seen during our work.
But in order to perform reliable IT Audit we need to use different IT Audit Tools and techniques. Such tools vary for different environments – for example for Windows environment we would use some tools provided by Microsoft company (e.g. MS Security Base Line Analyzer). And for UNIX environment these tools will be completely different. 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 in each case while performing IT Audit work you need to use different IT Audit Tools. This will significantly reduce the amount of manual work you need to perform.
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 another very challenging task, as you need to consider all issues which came to your attention during the IT Audit work. You need to combine all these issues, sort them, and conclude on which of them will go to final report. As a rule, this is done through classification of findings based on their criticality and impact to the business operations of the company. You can sort all isues as having Low, Medium or High impact. Usually we report only Medium and High findings to the management of the company. And the Low findings are reported only to local IT management in order to address the risk.
