Cyber security isn’t only a concern for large corporations. For a small business in Frankston or across the Mornington Peninsula, a compromised email account, lost laptop or ransomware incident can interrupt operations, affect customers and damage years of hard-earned trust.

The good news is that improving your security doesn’t have to mean building a complex technology department. A few practical controls can significantly reduce your exposure and help you respond confidently when something goes wrong.

The Australian Cyber Security Centre (ACSC) recommends that small businesses begin with foundational measures such as multi-factor authentication, software updates and regular backups. Email protection and staff awareness are equally important because many attacks begin with a convincing message or stolen password.

Here are five steps you can take to create a stronger cyber security foundation.

1. How can multi-factor authentication protect your most important accounts?

Multi-factor authentication (MFA) adds another layer of protection when someone signs in. Instead of relying only on a password, MFA asks for a second confirmation, such as a code from an authenticator app or an approval on your phone.

This matters because passwords can be guessed, reused or stolen through phishing. Even if a criminal obtains a password, MFA can make it much harder for them to access the account.

Which accounts should you protect first?

Prioritise accounts that would create the greatest business risk if compromised:

• Business email and collaboration platforms, such as Microsoft 365 or Google Workspace
• Online banking and payment systems
• Accounting and payroll software
• Customer relationship management systems
• Cloud storage and business applications
• Remote access tools and administrator accounts
• Social media and website administration accounts

Where possible, use an authenticator app rather than SMS. Authenticator apps generally provide stronger protection and don’t depend on your mobile service.

Make MFA a standard requirement for every team member. Store backup codes securely and establish a process for replacing a lost or damaged phone.

The result is simple: one stolen password is less likely to become a full business compromise.

2. How do reliable backups help your business recover?

A backup gives you a recovery path when data is deleted, corrupted, lost or encrypted by ransomware. Without a tested backup, an incident can force you to rebuild critical information from memory or negotiate with criminals.

Back up the information your business needs to operate, including:

• Accounting, payroll and invoicing data
• Customer and supplier records
• Contracts and important business documents
• Website files and databases
• Shared folders and cloud documents
• Email and other cloud-based business information
• Industry-specific records and systems

Automatic backups are more reliable than asking staff to remember to copy files manually. Consider the 3-2-1 approach:

• Keep at least three copies of important data
• Use two different types of storage
• Keep one copy off-site or in the cloud

Your backup system should also be protected from the same incident as your main systems. For example, a backup that is permanently connected to a compromised network may also be encrypted by ransomware.

Most importantly, test your backups regularly. A successful backup notification doesn’t always mean you can restore the files you need. Schedule restore tests at least quarterly and document how your team would recover essential systems.

Whole IT helps small businesses with data backup and cybersecurity hardening, including backup verification and integrity checks. That means you’re not only making copies of your data: you’re building a practical recovery plan.

3. Why are software and device updates a cyber security priority?

Updates close known security gaps before criminals can exploit them. When software vendors discover vulnerabilities, they release patches to fix them. Delaying those updates leaves an open door on computers, phones, servers and network devices.

Turn on automatic updates where appropriate for:

• Windows and macOS computers
• Mobile phones and tablets
• Web browsers
• Microsoft 365 and other business applications
• PDF readers and collaboration tools
• Antivirus and endpoint protection software
• Modems, routers and Wi-Fi access points
• Servers, printers and other connected devices

You should also remove applications and accounts you no longer use. Old software can create unnecessary risk, particularly if it no longer receives security support.

For a small business, it helps to create a regular patching routine. You might review device and application updates monthly, while allowing critical security updates to install sooner.

Don’t overlook staff working remotely. A laptop used at home or while travelling still connects to business systems and needs the same update standards as an office computer.

Keeping devices current reduces avoidable vulnerabilities and supports a more stable, reliable working environment.

4. How can you make business email safer?

Email security protects your business from phishing, invoice fraud and stolen credentials. Criminals often impersonate suppliers, customers, managers or financial institutions. Their messages may look genuine and create urgency around an invoice, payment or account problem.

Start with the security controls available through your email provider:

• Enable spam and phishing filters
• Turn on malicious link and attachment scanning
• Restrict automatic forwarding to external addresses
• Review sign-in alerts and unusual login activity
• Protect administrator accounts with MFA
• Keep your email platform and connected applications updated

Your business domain can also be configured with SPF, DKIM and DMARC. These settings help email providers identify messages that are authorised to come from your domain and make it more difficult for criminals to impersonate your business.

Technology is only part of the solution. Establish a clear payment verification process. If someone requests a change to bank details, ask staff to confirm it through a trusted phone number or another known channel. Don’t rely on the contact details included in the suspicious email.

The same rule applies to urgent requests for gift cards, transfers, password resets or sensitive information.

A short verification call can prevent a costly mistake.

5. How can staff awareness strengthen your first line of defence?

Well-informed staff are one of your strongest cyber security controls. Your team doesn’t need to become a group of technical specialists. They need clear guidance, regular reminders and an easy way to ask for help.

Train staff to recognise:

• Unexpected invoices or payment requests
• Urgent messages demanding immediate action
• Suspicious links or unusual attachments
• Slightly altered email addresses
• Fake delivery, banking, payroll or government notifications
• Requests for passwords or authentication codes
• Unusual messages appearing to come from a manager or supplier

Create a simple reporting process. Staff should know exactly who to contact if they click something suspicious, lose a device or notice unusual account activity.

Make early reporting a positive behaviour. People may hesitate to admit a mistake if they expect blame. A fast report gives your IT provider more time to secure accounts, isolate devices and limit the impact.

New starters should receive cyber security guidance as part of their induction. Existing staff should receive short refreshers throughout the year rather than one lengthy session that is quickly forgotten.

You can also use safe phishing simulations and practical examples to help your team recognise common scams. Whole IT provides cybersecurity assessments and staff phishing awareness training to help identify gaps and build confidence.

A security-aware team makes safer decisions every day: not only after an incident.

What should Frankston businesses do first?

You don’t need to complete every improvement at once. Start with the controls that provide the greatest immediate benefit:

1. Enable MFA on email, banking, accounting and administrator accounts.
2. Confirm that critical data is backed up automatically.
3. Check that computers, phones, applications and network devices are updated.
4. Review email filtering and introduce payment verification procedures.
5. Give staff clear guidance on scams and incident reporting.

Then create a simple improvement schedule. Review your access permissions, backup tests, software updates and staff awareness every few months. Your business changes over time, so your cyber security should evolve with it.

It’s also worth checking the ACSC’s Small Business Cyber Security Guide for practical Australian guidance.
