How to gain IS Audit experience for CISA

By Chidambaram Narayanan, , 2 min read

When I cleared my CISA, I thought my career was about to take off in a new direction.

I imagined diving into system audits, testing IT controls, and reviewing cybersecurity frameworks.

But reality hit differently.

Despite being certified, I was told — “You don’t have IS audit experience yet.”

That was the moment I realized: passing the exam was the peak of learning, but not the start of practice.

So instead of waiting for the opportunity, I decided to build it myself.

1) Start Where You Are: Look for IT in Every Audit

Every modern process — payroll, procurement, inventory, payments — runs on IT systems. So instead of waiting for a “pure IT audit,” I began identifying IT dependencies in my regular audits:

  • What systems process the transactions?
  • Who has access to change master data?
  • How are system-generated reports validated for accuracy?
  • Is there any evidence of change management or user access reviews?

These questions turned my financial audits into hybrid audits — and gradually, my work started reflecting IT control coverage.


2) Volunteer for Anything Tech-Related

I made it a point to volunteer whenever internal audit or compliance needed help with:

  • ERP access reviews
  • System implementation testing
  • Backup or change management checks
  • Policy and cybersecurity awareness reviews

Even if I was just documenting walkthroughs or checking logs, I was gaining exposure to real IT control environments — and learning from the IT audit team in the process.


3) Build Practical Skills on the Side

I realized knowledge alone isn’t enough — I needed to see how controls work in action. So I began:

  • Exploring ISACA’s Audit Programs for sample testing steps.
  • Taking short virtual labs (like TryHackMe and Cybrary) to understand logs, vulnerabilities, and system configurations.
  • Practicing data analysis using Excel and Power BI — after all, IT audit is about data, not just systems.

Every new skill gave me practical grounding for when I’d eventually lead an IS audit.


4) Network and Volunteer Outside Work

I reached out to peers in ISACA and other professional circles — and found that many chapters have volunteer-driven audit simulations, mentorship circles, or awareness campaigns. Even helping a nonprofit review its IT policies or basic security setup counts as real-world exposure.


5) Track and Build an “Experience Portfolio”

I started maintaining a personal log:

  • What IT-related procedures I performed
  • What controls I reviewed or tested
  • What systems I learned about
  • What outcomes or findings emerged

This record became my unofficial IS Audit Experience Portfolio — something I could confidently present when opportunities arise.


In short, experience isn’t something someone hands you. It’s something you build — one control, one walkthrough, one log review at a time.
