Embarking on the journey to identify critical access logs is the first task in your audit checklist. But why is it so crucial? Access logs are the breadcrumbs of user activity, and knowing which ones to focus on can unravel the secrets of any unauthorized attempts. Arm yourself with tools like Splunk or ELK Stack to streamline this process.

Anticipate challenges such as data overload. How can this be remedied? Efficient tools and a good grasp of your organization’s security infrastructure are your allies. Make sure to grasp the role of these logs, for they are pivotal in snooping out irregularities that might slip under the radar otherwise.
