Cybersecurity for Business:
Why the Essential Eight matters
Practical protection for real businesses
Cybersecurity is no longer just a concern for large banks and government agencies. If you own a clinic, an online shop, a booking system, or even if you run your business from a laptop, you're at risk. If you're handling customer or patient data, privacy and compliance are not optional; they’re legal requirements. This is where the Essential Eight comes in. Developed by the Australian Cyber Security Centre (ACSC), the Essential Eight is a straightforward framework designed to protect your business from common cyber threats. Think of it as your essential digital toolkit—practical, proven, and necessary.
What Is the Essential Eight?
Eight essential mitigation strategies to lower the risk of malware, ransomware, and unauthorised access:
Application control: Block unapproved software from running. Stops malware before it starts.
Patch applications: Keep apps like browsers, PDFs, and plugins current. Vulnerabilities get fixed fast.
Configure Microsoft Office macro settings: Prevent macros from running automatically—one of the oldest tricks in the book for malware.
User application hardening: Disable features you don’t need, like Flash or ads in browsers.
Restrict administrative privileges: Limit who has system-level access. Stops malware from spreading through admin rights.
Patch operating systems: Run updates regularly. Critical for closing security holes and staying protected.
Multi-factor authentication (MFA) adds a second layer to logins. Even if your password is stolen, your account will not be.
Regular backups: Schedule daily or weekly backups that are tested and stored safely. This way, if disaster strikes, you’ll be ready.
Even implementing these at a basic level dramatically improves your defences. They're scalable, and ACSC outlines three maturity levels depending on your risk profile.
Why Privacy and Compliance Matter
Privacy Act 1988 & the Australian Privacy Principles (APPs)
Personal data refers to any information that can identify an individual, such as names, addresses, phone numbers, and email addresses. Various laws and regulations govern the handling of this data. These guidelines specify how personal data is to be collected, detailing the type of information gathered and the methods used. They establish secure storage protocols to protect against unauthorised access and outline permissible uses of personal data, including marketing, and conditions for sharing or disclosing it to third parties, thereby safeguarding individuals' privacy rights.
Notifiable Data Breaches (NDB) scheme
In the event of a serious breach of personal data or privacy, take specific steps. First, inform the affected individuals about what happened, what data was compromised, and how they can protect themselves. Additionally, notify the Office of the Australian Information Commissioner (OAIC), the government body overseeing privacy laws and data breaches. This ensures appropriate action and guidance can be provided. In summary, communicate with affected individuals and relevant authorities to address the issue transparently.
