Information security risk assessment in 5 steps (no consultant-speak)
A risk assessment sounds heavy, but it is just structured thinking about what can go wrong. Here is how to do one yourself in five understandable steps.
By Limburg Cyber Group
A risk assessment is the foundation under any serious security approach, and under NIS2 even an explicit expectation. Yet the word puts people off. Unjustly: at its core it is simply structured thinking about what can go wrong and what you do about it. Here it is in five steps, without jargon.
Step 1: map your crown jewels
Start with what you have to protect. Which data and systems can your business not do without? Client files, financial records, your email, that one system everything runs on. You cannot protect everything equally heavily, so determine what is really important.
Step 2: consider what can go wrong
For each crown jewel, run through the threats. Think of: outage, theft, ransomware, human error, a hacked account, a rogue supplier. You do not have to be exhaustive, but do be realistic.
Step 3: estimate likelihood and impact
For each risk, two simple questions: how likely is it (low/medium/high) and how bad is it if it happens? The combination determines urgency. A risk that is both likely and severe you tackle first; something unlikely with small impact can wait.
Step 4: choose your measures
For each important risk, decide what you do. Usually that is: reduce (take a measure, such as MFA or backups), transfer (for example insure), or consciously accept if likelihood and impact are low. Accepting is a valid choice too, as long as it is made consciously.
Step 5: record and repeat
Put the outcome in a simple overview: risk, estimate, measure, who is responsible. This document is immediately your evidence of “demonstrable control” towards clients and regulators. Repeat the assessment yearly or on major changes.
Starting small is fine
Your first risk assessment does not have to be perfect. A simple version on one page is infinitely better than none. It brings focus: you suddenly know where to direct your energy.
