The Essential Eight Explained

Australia, like many other countries, has faced its share of cybersecurity challenges. Recent incidents in health insurance, vehicle, energy, and even government departments have highlighted the vulnerabilities that organisations face in an increasingly interconnected digital world. From data breaches to ransomware attacks, the need for comprehensive cybersecurity measures has never been clearer.

“The Essential Eight” strategies, developed by the Australian Signals Directorate (ASD), provide a roadmap for businesses to enhance their cybersecurity resilience. In the aftermath of recent incidents, these strategies have gained even greater relevance. Let’s delve into how each of them plays a pivotal role in in today’s IT environment.

1. Application Control

There are extreme risks associated with unapproved applications and unauthorised software. Application ‘whitelisting’, a fundamental aspect of “The Essential Eight,” allows organisations to regain control over their digital environment, preventing malicious software from compromising their systems.

2. Patch Applications

The importance of keeping software and operating systems up to date cannot be overstated, especially in light of recent attacks that may have exploited vulnerabilities. Timely patching remains a crucial strategy to defend against cyber threats.

3. Configure Microsoft Office Macro Settings

Cybercriminals often use Microsoft Office macros to deliver malware. Configuring macro settings is an essential defence to mitigate the risk of malware infiltration in a cloud-based environment.

4. User Application Hardening

In the wake of web-based attacks and malware distribution, hardening user applications, particularly web browsers and email clients, has become paramount. These measures help protect cloud applications and data.

5. Restrict Administrative Privileges

Restricting administrative privileges is essential. It is no surprise that unauthorised access and privilege escalation, leaves organisations wide open to threats, but nonetheless, its an important reminder to upgrade these systems if you haven’t already.

6. Patch Operating Systems

The need to maintain the security of underlying operating systems and software applications in a cloud environment is ever more critical. Regular patching remains a cornerstone of cloud security.

7. Multi-factor Authentication (MFA)

In a landscape where credential theft is a common method of attack, MFA is a powerful tool. Recent events underscore the importance of adding an extra layer of authentication to secure data and resources effectively.

8. Regular Backups

Data protection has never been more crucial. Regular backups are not just a best practice; they are essential for data recovery and business continuity.
