The ACSC's Essential Eight
The Australian Cyber Security Centre (ACSC) defines the Essential 8 as a set of foundational cybersecurity strategies designed to safeguard systems from a broad range of cyber threats.
These strategies emphasise proactive prevention, minimising the impact of incidents, and ensuring operational resilience. The Essential 8 includes critical measures such as timely application patching, restricting administrative privileges, and enhancing email security.
This framework is recommended for organisations across all sectors as a comprehensive baseline for strengthening their cybersecurity posture.
Who should consider the Essential 8?
The Essential 8 is crucial for any company that values the security of its systems, data and operations.
This framework is particularly relevant for businesses across industries such as finance, healthcare, legal, government, and education, where sensitive information and critical infrastructure are at high risk of cyber threats.
Organisations of all sizes- from small businesses to large enterprises- should consider implementing the Essential 8 to safeguard their digital assets and maintain operational continuity in the face of growing cyber threats.

Why your company should consider the Essential 8?

Cyber threats continue to evolve in sophistication and frequency, making it increasingly important for organisations to adopt comprehensive security measures.
The Essential 8 provides a structured approach to fortifying systems against a wide range of cyberattacks, such as ransomware, phishing, and data breaches. By implementing these strategies, businesses can reduce their vulnerability, minimise the impact of incidents when they occur, and ensure that critical data remains secure.
Moreover, complying with the Essential 8 helps companies meet regulatory requirements and industry standards, protecting their reputation and customer trust.
Where should the Essential 8 be implemented?
The Essential 8 should be implemented wherever digital systems and sensitive data are critical to the functioning of an organisation. This includes corporate networks, cloud environments and any other infrastructure that supports business operations.
The framework is especially necessary in industries where compliance with strict cybersecurity regulations is mandated, such as finance, healthcare, and government.
By ensuring the Essential 8 is embedded into their IT practices, businesses can protect themselves from data breaches, financial loss, and reputational damage.

The Essential 8

Application Control
Application control involves restricting the execution of unauthorised software on systems and networks.
​
It ensures that only approved applications can run, significantly reducing the risk of malware and other malicious software from compromising the system.

Patch Applications
This strategy focuses on regularly updating software applications to address known vulnerabilities.
​
By promptly applying security patches, organisations can close potential entry points for cybercriminals and maintain the integrity of their software system.

Configure Microsoft Office macro settings
This strategy involves managing the settings for Microsoft Office macros to prevent malicious code execution.
​
By disabling macros from untrusted sources and implementing strict controls, organisations can mitigate the risk of macro-based malware attacks.

User Application hardening
This approach involves configuring user applications to enhance their security posture. It includes disabling unnecessary features, removing outdated plugins, and implementing strict security settings to reduce the attack surface of commonly used applications.

Restrict Administrative Privileges
This strategy limits the number of users with administrative access to systems and networks.
​
By implementing the principle of least privilege and regularly reviewing access rights, businesses can minimise the potential impact of compromised user accounts

Patch Operating Systems
Similar to patching applications, this strategy focuses on keeping operating systems up-to-date with the latest security fixes.
​
Regular OS Patching helps protect against unknown vulnerabilities and ensures that systems have the latest security features and improvements.

Multi-Factor Authentication
This strategy adds an extra layer of security by requiring users to provide two or more pieces of evidence to verify their identity.
​
By implementing MFA, organisations can significantly reduce the risk of unauthorised access, even if passwords are compromised.

Regular backups
This strategy involves creating and maintaining copies of critial data and systems.
​
By implementing a robust backup strategy, organisations can ensure businesses' continuity in the event of data loss, system failures, or cyberattacks, allowing for quick recovery and minimal disruption.
