Let’s face it — cybersecurity isn’t exactly the kind of topic you tend to chat about at the dinner table. But it probably should be. Especially when cyberattacks are on the rise, scams are getting smarter, and the digital world is where we live, shop, bank, and build businesses.
So if you’re looking to learn cybersecurity (not the jargon-filled, IT-only kind, but the practical, everyday kind) you’re in the right place. You don’t need a computer science degree or a tinfoil hat; a bit of know-how, the right tools, and some good digital habits will go a long way.
Whether you’re running a small business, managing your finances online, or just sick of scam texts from “Australia Post”, these cybersecurity basics will help keep you safe.
Why Cyber Security Matters More Than Ever
Australians are more connected than ever before. The average Australian household has 25 internet-connected devices, from smartphones to smart fridges. That’s 25 open doors for cybercriminals if you’re not careful.
And they’re not just going after big businesses or government departments anymore. Small businesses and individuals are now their favourite targets, simply because most don’t have strong defences in place.
The truth of the matter is that cyber attacks are no longer a matter of if. They’re a matter of when.
The best defence is education. So, if you want to avoid being the next victim, it’s time to get across some cyber security basics.
Cyber Security Basics: 5 Things Every Aussie Should Know
1. Not All Threats Come Through Email
Yes, phishing emails are still common (and still catching people out). But these days, threats also come through fake websites, infected ads, dodgy apps, public Wi-Fi, and even compromised browser extensions. And they look slicker than ever before.
If you’ve ever clicked “Allow” on a pop-up without thinking, you might’ve just opened the door to malware.
Learn cyber security rule #1: If it seems off, it probably is. Don’t click. Don’t download. Don’t enter your details.
2. Passwords Are Still a Big Problem
Using “Password123” or your dog’s name and year of birth? You’re not alone, but you’re also not protected.
Hackers can crack weak passwords in seconds using automated tools. And if you’re reusing passwords across accounts, one breach means all your logins are compromised.
Here’s what you can do:
- Use a password manager
- Turn on two-factor authentication (2FA)
- Change passwords often (yes, it’s annoying, but it’s not as annoying as getting hacked)
3. Antivirus Alone Isn’t Enough
Think your antivirus software is a digital forcefield? Think again. Most free antivirus programs don’t detect zero-day attacks, ransomware, or advanced malware.
The threats have evolved. Your defences need to as well.
Modern security means layered protection: think firewalls, malware scanners, secure hosting, penetration testing, and regular audits — not just the stuff that comes pre-installed.
4. Updates Aren’t Just a Nuisance
Those software updates you’ve been snoozing on for six months? They’re not just there for fun; they usually patch known security holes.
Outdated apps and plugins are a hacker’s dream.
So, if your business website is running on old WordPress themes or you’re ignoring your device’s security updates, you’re basically inviting trouble.
Here’s a pro tip: To make it easy on yourself, turn on automatic updates, apps, and devices as soon as they’re available.
5. Your Website is a Target Even If You Think It’s “Too Small”
Think no one would bother hacking a small tradie site or blog shop? You’d be wrong.. Hackers don’t always go for the big fish. They cast a wide net and look for the easiest catches.
That could be:
- Weak admin passwords
- Unpatched plugins
- No SSL certificate
- No firewall or threat monitoring
And once they’re in, they can steal customer data, inject malicious scripts, or redirect traffic to scam sites without you noticing until it’s too late.
