IT Security Audit: Do You Need One?

An IT security audit is a high-level, systematic evaluation of the security of a company’s information system. Do you need one? Absolutely. It is vital that every company performs a security audit at least once or twice a year. Continue reading and we’ll explain in more detail why you should perform such an audit.

How Does An IT Security Audit Work?

Here’s how an IT security audit works. The first step is to define the assessment criteria. This determines the overall objectives the company needs to address in the audit, then breaking them down into priorities. Industry standards such as GDPR are things that must be considered. Maintaining a threat catalogue of all discovered risk vectors and utilize outside resources when possible is also looked at. Overall, the organisation’s priorities should not influence the outcome of the audit.

The second step is to prioritise your success criteria and business objectives. The necessary tools to complete the audit are identified and procured, and the methodologies to perform the audit are defined. An appropriate questionnaire or survey is needed to gather the correct data. This is what creates a great audit.

The third step is to conduct the audit. Providing the appropriate documentation and perform due diligence throughout the process is key. Monitoring the progress of the security audit is vital and the data points collected for accuracy. Throughout the audit, details will be uncovered that require further examination, but these will be prioritised first.

The fourth step is the completion of the audit and sharing the results. At this stage a list of action items will be created based on the audit’s findings. Then items that need fixing will be prioritised to remediate the security items discovered. Overall, it is supposed to uncover risks to the company so that action can then be taken.
