Your Cybersecurity Checklist

Cybersecurity often gets pushed aside when you’re handling the day-to-day realities of running a business. But whether you realise it or not, your systems are working around the clock — and they’re only as strong as the attention you give them.

A Practical, No-Fuss Guide to Cybersecurity Best Practices

You don’t need to be a technical expert to protect your business and manage your IT. You just need a plan that’s simple, structured and repeatable. Let’s walk through the key elements of your IT security checklist.

1. When Did You Last Check Your Antivirus?

Antivirus software isn’t exciting, but it’s a foundational part of cybersecurity best practices. Always ready, but only effective if it’s healthy and up to date. Check the essentials:

• Is your subscription active?
• Are automatic updates enabled?
• When was the last full system scan? Are automatic regular scans enabled?
• Are all devices — including remote laptops — covered?

2. Is Your Firewall Actually Doing Its Job?

Your firewall acts as a fence around your business. Check if your firewall is being actively managed and if intrusion-prevention features are turned on. For most organisations, the firewall is installed once and rarely touched again. Taking the time to review it can significantly improve your overall business cybersecurity posture.

3. How Strong Are Your Passwords, Really?

Passwords are still one of the biggest vulnerabilities in any organisation. Attackers rely on predictable passwords. A safer approach for every user would be to:

• Use long, unique passwords
• Store all passwords in a business-grade password manager
• Avoid personal details
• Set clear internal password guidelines

4. Have You Enabled MFA Everywhere You Can?

If passwords are the first lock on your door, Multi-Factor Authentication (MFA) is the deadbolt — simple, strong and incredibly effective. Turn it on for:

• Email accounts
• Cloud platforms (Microsoft 365, Google Workspace, Xero)
• VPN and remote access
• Admin-level accounts

5. Are Your Devices Updated and Patched?

Updates often feel like interruptions, but in cybersecurity terms, they’re frontline defence. Unpatched systems are among the most exploited weaknesses. Good patch management looks like:

• Automatic updates turned on
• Regular patching for apps and operating systems
• Tracking older or unmanaged devices
• Reviewing third-party software, not just Windows or macOS

This step closes the majority of known vulnerabilities.

6. Do You Have a Clear Offboarding Process?

Technology isn’t your only risk point — people and processes play a major role too. When someone leaves your organisation, access must be removed quickly and cleanly to reduce human error or oversight. A good offboarding process includes:

• Disabling accounts
• Reclaiming devices
• Removing access to cloud tools
• Updating all shared passwords
• Reviewing integrations or automations they set up

7. Are You Following the Essential Eight Cybersecurity Strategies?

If you’re operating in Australia, the Essential Eight cybersecurity model is a practical benchmark. It’s designed to help businesses reduce the risk of common cyberattacks. Essential Eight includes:

• Application control: Using only authorised software in your IT ecosystem
• Patch applications: Installing updates for all software to fix vulnerabilities
• Patch operating systems: Installing updates for operating systems to limit risk
• Multi-Factor Authentication: Enabling MFA to log into accounts
• Restrict admin privileges: Limiting the number of users who have administrative access
• Restrict Microsoft Office macros: Disabling macros (or repetitive commands) from untrusted sources
• User application hardening: Configuring and securing applications to reduce their attack surface
• Regular backups: Creating and maintaining regular backups of important data

Final Thought: Cybersecurity Doesn’t Need to Be Complicated

Strong cybersecurity doesn’t require technical expertise — just awareness and consistency. Work through this list, one step at a time. Small improvements can make a big difference in protecting your business, staff, and clients.
