The Pareto Principle in Cybersecurity Risk Management: Focus on What Matters Most

The 80/20 rule, also known as the Pareto Principle, is a powerful concept that can make cybersecurity risk management way less daunting for businesses. For example, a small business might find that addressing just a handful of key vulnerabilities, such as unpatched software or weak passwords, could dramatically reduce the risk of a major breach. With all the security measures you could implement, it's easy to feel overwhelmed.

So, where to start?

The Pareto Principle tells us to focus on the 20% of risks that could cause 80% of the damage to your business. By zoning in on these areas, you can make a real impact with your cybersecurity efforts without driving yourself (or your team) crazy.

Vulnerabilities and Outsider Risk: Prioritise What Hurts Most

In cybersecurity, the sheer number of vulnerabilities out there can seem daunting. To start effectively managing risk, start by identifying the 20% of vulnerabilities that could cause the most chaos for your business. These are the low-hanging fruit, the critical gaps that bad actors are most likely to exploit. Make tackling these a priority, close those gaps and sleep a little easier at night.

Access Management: Protect the Crown Jewels

Not every system is created equal. Some hold your most sensitive or critical data, your "crown jewels" in other words. These are the systems that deserve the most attention when managing access. Make sure you've got tight controls around these critical systems to keep unauthorised folks out. And, monitoring these systems for anything weird is a smart move. Spot issues early before they become full-blown crises, such as unauthorised access attempts, unusual data transfers, or unplanned changes to critical systems.

Insider Risk: Watch the Gatekeepers

Not all employees have the same level of access, and not all access carries the same risk. When managing insider risk, focus on the folks with the keys to the kingdom. There's no point in locking down the intern's access to marketing PowerPoint slides, but it's crucial to keep an eye on those with privileged access to critical data & the cash. Watch out for unusual access patterns, like attempts to access systems at odd hours, repeated failed login attempts, or accessing data that isn't typically needed for someone's role, sometimes the biggest threat comes from the inside.

Threat Actors: Know Your Adversary

Another key part of applying the Pareto Principle to cybersecurity is knowing who might come after you, and what the most likely entry method is. Do you receive a lot of email traffic? How about handling lots of sensitive information like PII or credit card data? If yes, then email security and data protection should be top of the list. If you're exchanging a lot of files, make sure you've got solid malware protection. By figuring out where the most attacks are likely to come from, you can set up defences that count.

Constant Monitoring: Stay Ahead of Threats

The final piece of the puzzle is monitoring. It’s not enough to just put controls in place, you need to make sure they’re working. Constant monitoring keeps you ahead of the curve and helps you catch problems before they turn into serious incidents. By first focusing your monitoring on the 20% of areas that could cause 80% of the damage, you can maintain an effective security posture without drowning in alerts.

Start with the Essentials

Applying the Pareto Principle to cybersecurity won’t eliminate all risk, but it helps make sure you're putting your resources where they matter most. By focusing on the critical vulnerabilities, managing access to the important stuff, understanding where the biggest threats come from, and keeping an eye on things, you can take meaningful steps toward securing your business, even if you're not sure where to begin. And once you get started, then it's about making incremental improvements as you go!
