Know More About Essential 8
Overview of the Essential Eight
The Essential Eight is a critical cybersecurity self-assessment tool developed by the Australian Cyber Security Centre (ACSC) to help organisations protect against cyber threats. This tool specifically targets Microsoft Windows-based internet-connected networks, providing a structured approach to enhance cybersecurity through a three-tier Maturity Model:
- Maturity Level Zero: Not yet aligned with the mitigation strategy.
- Maturity Level One: Partly aligned with the mitigation strategy.
- Maturity Level Two: Mostly aligned with the mitigation strategy.
- Maturity Level Three: Fully aligned with the mitigation strategy.
These maturity levels offer organisations a clear framework to assess and improve their cybersecurity measures progressively.
The Essential Eight mitigation strategies are as follows:
- Application Control: This strategy restricts unauthorised software, preventing malicious programs from breaching your network. Application whitelisting technologies ensure only known good files are allowed, significantly reducing the risk of malware.
- Patch Applications: Regularly updating software to apply functionality and security fixes is crucial. Patching applications prevent attackers from exploiting known vulnerabilities to breach the network.
- Configure Microsoft Office Macro Settings: Macros can automate tasks but also pose a risk if they contain malicious code. Configuring macro settings to block untrusted macros can prevent unauthorised access and malware infections.
- User Application Hardening: Reducing the attack surface by blocking or removing software commonly used to deploy malicious code helps protect against disruptions in ICT services.
- Restrict Administrative Privileges: Limiting admin access to essential functions only and regularly reviewing these privileges helps prevent unauthorised access and potential security breaches.
- Patch Operating Systems: Keeping operating systems up-to-date with the latest patches ensures that known vulnerabilities are addressed. Unsupported operating systems should be replaced to maintain security.
- Multi-factor Authentication (MFA): Implementing MFA, which requires at least two forms of authentication, greatly enhances security by making it difficult for attackers to gain unauthorised access to sensitive information.
- Regular Backups: Regularly backing up important data, software, and configuration settings ensures data integrity and availability. Testing backups periodically ensures that data can be restored when needed, and restricting access to backups prevents unauthorised modifications or deletions.
Benefits of Implementing the Essential Eight
Adopting the Essential Eight provides a robust baseline for cybersecurity, protecting against a wide range of threats. By following these strategies, organisations can:
- Enhance their overall security posture.
- Comply with government cybersecurity standards.
- Build trust with clients and stakeholders through demonstrated commitment to security.
For organisations looking to implement these strategies effectively, the Essential Eight Assessment Process Guide offers detailed steps and methodologies to ensure comprehensive protection.
