Making Sense of Security Audits: A Human Guide to ISO 19011 and ISO 27001

Written by CourseMonster | 26/06/2025 11:39:30 AM

Let’s face it—security audits aren’t exactly what most of us dream about at night. The words “ISO standards” and “audit methodology” might make your eyes glaze over faster than a mandatory compliance training video. But here’s the thing: behind all that technical jargon lies something incredibly important—making sure your organization’s sensitive information stays protected in an increasingly risky digital world.

So grab your favorite beverage, and let’s break down this audit business into something that actually makes sense to those of us without “auditor” in our job titles.

 

Why Should You Care About These ISO Standards?

Think of ISO 27001 as your security playbook—it tells you what you need to do to keep information safe. It’s like the recipe for a security cake.

ISO 19011, on the other hand, is your cooking technique—it doesn’t tell you what ingredients to use, but rather how to mix them together properly. It’s all about the method.

Together, they’re like having both a great recipe AND knowing how to cook. One without the other leaves you with either ingredients you don’t know how to use or excellent technique but nothing to make!

Step 1: Figure Out What You’re Actually Doing

Before diving headfirst into audit-land, take a breath and ask yourself three simple questions:

  • Why are we doing this? Is it because you need that ISO certification to win new clients? Or because your boss is worried about security risks? Be honest about your objectives.
  • What parts of the company are we looking at? Maybe it’s just the IT department, or perhaps it’s the whole enchilada. Either way, define your boundaries.
  • What are we measuring against? You need a yardstick to know if something’s good or bad.

Pro tip: Write these down somewhere visible. When things get complicated later (and they will), you’ll thank yourself for having this clarity.

Step 2: Plan Your Audit Adventure

Now it’s time to map out your journey. This isn’t something you do on the fly—it needs structure:

  • How often will you audit? (Quarterly? Annually?)
  • Which teams are getting the audit spotlight?
  • Who’s going to do the auditing?

Remember how your parents always said they’d check your room more often if it was usually messy? Apply that same logic here. High-risk areas deserve more frequent check-ins than the parts of your organization that rarely see issues.

Step 3: Find People Who Know What They’re Doing

You wouldn’t ask a plumber to fix your car, right? The same principle applies to auditors.

Your audit team needs to understand both security AND how to conduct an effective audit. They should be:

  • Independent (no auditing their own work!)
  • Knowledgeable about security controls
  • Good at asking questions that make people think
  • Able to spot discrepancies without making people feel attacked

And please, rotate your auditors occasionally. Even the most objective person develops blind spots over time.

Step 4: Create Your Game Plan

This is your detailed battle plan that answers all the who-what-where questions:

  • “We’re auditing the finance department on Tuesday at 10 AM”
  • “We need to review the access control logs from the past quarter”
  • “We’re interviewing Sarah from IT security about incident response”

Share this plan with everyone involved—nobody likes surprise audits showing up like unexpected in-laws.

Step 5: Start With a Friendly Intro

The opening meeting sets the tone for everything that follows. If you come in like a stern teacher looking for troublemakers, guess what? People will hide things.

Instead, kick things off with:

  • A warm introduction
  • Clear explanation of what you’re doing and why
  • Reassurance that this is about improvement, not punishment
  • A chance for questions

Remember: “We’re all in this together” beats “I’m here to catch you doing something wrong” any day of the week.

Step 6: Do the Detective Work

This is where the rubber meets the road. You’re looking for evidence that security is actually happening, not just talked about in meetings.

Look at:

  • Risk assessments (are they thoughtful or just checkbox exercises?)
  • Security policies (does anyone actually read them?)
  • Access logs (who’s getting into what systems?)
  • Incident reports (what went wrong and did we learn from it?)

Don’t try to look at everything—you’ll drown in details. Instead, use smart sampling to get the big picture. It’s like checking a few apples to judge the whole barrel.

Step 7: Call It Like You See It

Be straightforward about what you find:

  • Things that look good? Great! Give credit where it’s due.
  • Things that could be better? Flag them as improvement opportunities.
  • Things that are clearly wrong? Those are your nonconformities.

For problems, be crystal clear: “The password policy requires 12 characters, but the system is configured to accept 8-character passwords” is much more helpful than “password controls are inadequate.”

Step 8: End on a Positive Note

When wrapping up, remember that how you deliver feedback is just as important as the feedback itself:

  • Summarize what you found
  • Acknowledge what’s working well
  • Explain issues without pointing fingers
  • Be open to questions and clarifications

Think of it less as a final judgment and more as a helpful review from a critical friend.

Step 9: Write It Down (But Make It Readable!)

Your audit report shouldn’t put people to sleep. Use clear language, visual aids, and a logical structure. Include:

  • What you looked at
  • What you found
  • What needs fixing
  • What’s working well

Pro tip: A good report is one that someone can actually use, not just file away and forget.

Step 10: Make Sure Things Actually Improve

The whole point of an audit is positive change. For each issue:

  • Make someone responsible for fixing it
  • Figure out why it happened in the first place
  • Fix it properly, not just with a band-aid solution
  • Check back to make sure the fix stuck

The Human Side of Auditing

When you combine ISO 19011’s approach with ISO 27001’s requirements, you get something powerful—a security program that actually works in real life, not just on paper.

Remember that behind every policy, control, and procedure are people trying to do their jobs. The best audits don’t just find problems—they help build a culture where security becomes second nature.

In a world where cyber threats keep getting scarier and regulations tighter, good security isn’t just a technical requirement—it’s a business necessity and a human responsibility.
