CISA: Real-world Information Systems Auditing

Information Systems Auditing: Stories from the Field

Hey there, tech community! Let's talk about real-world information systems auditing. Through our CISA certification course, we've seen what makes audits succeed (and fail). Here's what we've learned from the trenches.

Modern Audit Reality

Remember when auditing meant endless checklists? Those days are gone. A financial services client recently showed us how modern auditing works:

Their audit team didn't start with checklists. Instead, they mapped out how their systems actually worked. They looked at cloud services, legacy systems, and most importantly - how everything connected. This revealed risks that no checklist would have caught.

"The real insights came when we stopped looking at systems in isolation," their lead auditor told us. By understanding system relationships, they found critical vulnerabilities that previous audits had missed.

Planning That Works

A healthcare organization recently nailed their audit planning. Instead of diving straight into testing, they spent time understanding their environment. They talked to system owners, watched operations in action, and identified what really mattered.

This approach paid off big time. They found several high-risk areas that previous audits had completely missed. Why? Because they looked at how systems were actually used, not just how they were supposed to work.

Control Testing in Real Life

Here's a story from a manufacturing company that gets it right. Instead of testing every possible control, they focus on what matters:

"We used to test everything," their audit manager shared. "Now we focus on controls that actually protect our critical operations." This targeted approach not only saved time but found more significant issues.

They spend time watching how controls work during normal operations. Often, they find controls that look great on paper but fall apart under real-world conditions. That's the kind of insight that makes audits valuable.

Evidence That Matters

One organization transformed their evidence collection after a simple realization: more evidence isn't better evidence. They now focus on quality over quantity.

Instead of gathering every possible document, they collect evidence that shows how controls actually work. Screenshots that demonstrate real issues. Logs that show actual problems. Documentation that matters.

Reports People Actually Read

A government agency revolutionized their audit reporting with one simple change: they started writing for their audience. Instead of technical jargon, they focused on:
