Why Patching Operating Systems Is Vital for Cybersecurity: A Guide to the Essential Eight
Keeping your operating systems (OS) up to date isn’t just about getting the latest features or a new look. It’s one of the most important steps you can take to protect your business from cyber threats. At Gray Area Consulting, we often compare unpatched systems to leaving your front door unlocked — you might be fine for a while, but eventually someone will notice and try to get in.
What Is Patching, Really?
Patching simply means applying updates released by software providers to fix bugs, improve functionality, and most importantly, close security gaps. These patches can address vulnerabilities that hackers actively look to exploit. When you’re running an outdated OS, you’re essentially driving with a cracked windscreen — it might hold up today, but it’s only a matter of time before it shatters.
The Essential Eight and Why Patching Is Front and Centre
The Essential Eight framework, developed by the Australian Cyber Security Centre (ACSC), outlines eight strategies that help organisations mitigate cyber risks. Two of these strategies focus specifically on patching:
- Patch operating systems
- Patch applications
The message is clear — if you’re not patching, you’re not protecting.
Why This Matters for Aussie Businesses
We’ve worked with small and medium businesses across Australia that have learned the hard way what skipping updates can cost. One Brisbane-based legal firm we supported had delayed patching their systems for months due to workload. They thought their antivirus and firewall were enough. Then came a ransomware attack through a vulnerability in their Windows OS. It took a weekend of urgent recovery work and a few grey hairs to get them back on track.
Had they followed the Essential Eight and kept their systems patched, the attack could’ve been stopped before it even began.
How Often Should You Patch?
Ideally, patches for operating systems should be applied within 48 hours of release, especially when the vulnerability is rated as critical. This is where having Managed IT Services really helps. At Gray Area Consulting, we automate patching as part of our service, so you don’t have to rely on good intentions or reminders.
The Risks of Skipping OS Updates
If you’re thinking, “We’ll do it next week,” consider what’s at stake. Delaying patches can expose you to:
- Ransomware attacks – where your files get locked until you pay up
- Data breaches – exposing client or staff information
- Compliance issues – especially if you’re in regulated industries like legal or healthcare
- Downtime – which can cost more than just money
How to Make Patching Part of Your Routine
Here’s a simple checklist to make OS patching easier:
- Enable automatic updates where possible
- Schedule regular patching windows (e.g., monthly)
- Use monitoring tools to track patch status
- Test critical updates in a controlled environment before rolling out
- Work with an MSP (like us!) to automate and manage the process
Don’t Forget About Third-Party Applications
While this article focuses on operating systems, it’s worth noting that patching applications is equally important. Programs like Microsoft Office, Adobe Reader, and even web browsers are common entry points for attackers if not updated regularly.
How We Can Help
At Gray Area Consulting, we take patching off your worry list. As part of our Managed IT Services, we include proactive patch management that aligns with the Essential Eight. That means faster updates, lower risk, and peace of mind.
If you’re unsure how well your patching strategy stacks up, we can also conduct a Cybersecurity Risk Assessment to give you a clear picture.
Wrapping Up
Patching your operating systems isn’t optional — it’s one of the most effective ways to stay ahead of cyber threats. Think of it like regular servicing for your car. Sure, it might seem like a hassle, but it keeps everything running safely and smoothly.
