Cybersecurity is crucial for any business, no matter the size. With cyber threats becoming more frequent and sophisticated, organisations need to be more vigilant than ever.
Protecting your business against these threats requires a comprehensive strategy that covers everything from system updates to employee education. A combination of practical measures, like the Essential 8 framework and CERT NZ’s critical controls, can significantly uplift your organisation’s security posture.
Here’s a closer look at the key cybersecurity measures businesses should consider and how frameworks like the Essential 8 and CERT NZ’s Critical Controls can help strengthen your defences.

What Are the Key Cybersecurity Measures?
To safeguard against the most common cyber threats—such as malware, ransomware, phishing, and data breaches—businesses must focus on addressing vulnerabilities in applications, operating systems, and user behaviours.
A strong cybersecurity posture involves the implementation of essential measures such as:
ACSC Essential 8
These strategies are developed by the Australian Cyber Security Centre (ACSC) and focus on practical, cost-effective ways to enhance your organisation’s cybersecurity:
1+2: Patch Applications and Operating Systems
Regularly update software and operating systems to close security gaps and prevent vulnerabilities from being exploited.
3: Multi-Factor Authentication (MFA)
Add an extra layer of security by requiring users to verify their identity with more than just a password.
4: Restrict Administrative Privileges
Limit admin access to essential personnel only to reduce the risk of unauthorised access to critical systems.
5: Application Control
Use application whitelisting to prevent malicious software from executing on your network.
6: Restrict Microsoft Office Macros
Disable macros in Office documents, which are often used to spread malware.
7: User Application Hardening
Harden web browsers and other user applications to prevent exploitation.
8: Regular Backups
Ensure that critical data is regularly backed up and securely stored, allowing quick restoration in the event of an attack.
CERT NZ Critical Controls
In addition to Australia’s Essential 8 strategies, many of which align with CERT NZ’s recommendations, CERT NZ also recognises additional cybersecurity practices to strengthen your defences, including:
- Provide and Use a Password Manager: Ensure strong, unique passwords across systems by using a password manager.
- Centralised Logging: Aggregate logs from all endpoints to monitor network activities and enhance incident detection.
- Security Awareness Building: Conduct regular training to educate employees on recognising threats like phishing and social engineering attacks.
- Asset Lifecycle Management: Maintain an up-to-date inventory of assets to ensure timely updates, patches, and secure disposal of outdated equipment.
- Network Segmentation and Separation: Divide networks into segments with strict access controls to limit the spread of malware.
Why Should Businesses Implement These Cybersecurity Measures?
As cyber threats become more sophisticated—especially with the rise of AI-driven cybercrime—they are also becoming harder to detect. This makes it crucial for businesses to adopt proactive security strategies. The financial impact of cybercrime is staggering and continues to grow. The costs go beyond direct financial losses from data breaches and ransomware attacks; businesses also face indirect costs such as operational disruptions, reputational damage, and legal expenses.
For small to medium-sized businesses, even a single cyberattack can be devastating, sometimes leading to closure. That’s why strong cybersecurity processes are essential. By implementing these measures, businesses can:
- Reduce Cyber Risk and Protect Against Common Attacks: By regularly patching applications and operating systems, limiting unnecessary administrative privileges, and controlling which applications can run, businesses can defend against common cyber threats like ransomware, phishing, and malware.
- Ensure Compliance and Avoid Penalties: In Australia, businesses must follow the Protective Security Policy Framework (PSPF) and the Notifiable Data Breaches (NDB) scheme. Similarly, in New Zealand, businesses must comply with the Privacy Act 2020. Implementing strong cybersecurity measures ensures compliance with these regulations and reduces the risk of penalties.
- Strengthen Incident Response and Minimise Damage: Regular backups, MFA, and restricted admin access help businesses recover faster after a cyber-attack. These steps make it harder for attackers to access critical systems, minimising the impact of breaches.
- Build Trust and Strengthen Cyber Resilience: Strong cybersecurity not only protects data but also builds trust with customers and partners. By securing your data, you safeguard your reputation and strengthen your ability to respond to future threats.
Building a Resilient Future
Investing in strong cybersecurity isn’t just about protecting data—it’s about securing the future of your business. By adopting frameworks like the Essential 8 and CERT NZ’s Critical Controls, businesses can significantly reduce cyber risks, improve incident response, and build trust with customers and partners.
