Cybersecurity Basics for Business Users

Category: Security Basics · Audience: Client · Updated: March 2026

Practical security habits every business user should follow to protect their accounts, devices, and company data. No technical knowledge required.

1. Use Strong, Unique Passwords

Every account should have its own password — never reuse the same one across multiple sites. Use your password manager (e.g. Keeper) to generate and store passwords. Aim for at least 14 characters.

Bad: Password123, Company2024, same password everywhere.

Good: A random string like Kx9#mP2v$nL7qR4w generated by your password manager.

2. Enable Multi-Factor Authentication (MFA)

MFA adds a second step to sign-in — usually an approval on your phone. Even if someone steals your password, they can't get in without the second factor. Enable MFA on every account that supports it, starting with email and Microsoft 365.

3. Think Before You Click

Phishing emails are the most common attack method. Before clicking any link or opening any attachment:

  • Check the sender's actual email address — not just the display name.
  • Hover over links to see where they really go.
  • Be suspicious of urgency — "Act now or your account will be locked" is a classic phishing tactic.
  • When in doubt, don't click. Call the sender directly to verify.

4. Lock Your Computer When You Walk Away

Press Windows key + L (Windows) or Ctrl + Command + Q (Mac) every time you leave your desk — even for a minute. An unlocked computer is an open door.

5. Keep Software Updated

Software updates include security patches that fix known vulnerabilities. Don't postpone them.

  • Windows: Let Windows Update run automatically. Restart when prompted.
  • Mac: Enable automatic updates in System Settings → Software Update.
  • Browsers: Chrome, Edge, and Firefox update automatically — just restart the browser when prompted.
  • Mobile: Enable auto-updates for apps and operating system on your phone.

6. Be Careful with USB Drives

Never plug in a USB drive you found or received unexpectedly. Malicious USB drives can install malware the moment they're connected. If someone leaves a USB drive on your desk or in a common area, hand it to your IT contact — don't plug it in.

7. Use Your Company Network and VPN

When working from home or a public location, connect to the company VPN if one is provided. Avoid using public Wi-Fi for work tasks without a VPN — public networks are not secure and can be monitored by attackers.

8. Don't Share Credentials

Never share your password with anyone — not colleagues, not managers, not IT support. ATS Systems will never ask for your password. If someone requests it, report it.

If a colleague needs access to something, the correct approach is for their administrator to grant them access — not for you to share your login.

9. Report Anything Suspicious

If something looks off — a strange email, an unexpected MFA prompt, a pop-up warning, or unusual behaviour on your computer — report it. Call ATS Systems on 07 3523 3660 or tell your IT contact. It's always better to report a false alarm than to ignore a real threat.

10. Know What to Do in an Emergency

If you think your account has been compromised or you've clicked something suspicious:

  1. Disconnect from the network (turn off Wi-Fi or unplug Ethernet).
  2. Call ATS Systems on 07 3523 3660 immediately.
  3. Don't try to fix it yourself — our team will guide you.
  4. Don't delete evidence — keep the email, browser tab, or error message open.

Remember: Security is everyone's responsibility. Attackers target people, not just technology. Staying aware and following these basics makes a real difference.
