The Essential Eight
Combine Essential Eight with broader cyber controls
What is the Essential Eight?
The Essential Eight is an Australian cyber security framework comprising eight crucial strategies from the ACSC’s “Strategies to Mitigate Cyber Security Incidents.” Introduced as a baseline cyber resilience model for Australian government and enterprise organisations.
Significantly Improve Security Posture
By implementing the Essential Eight, organizations can significantly improve their overall security posture, reducing their risk of a successful cyber attack.
Cost-Effective Approach
It is a cost-effective approach to cybersecurity, as it focuses on the most critical risks and does not require extensive investment in technology.
National Protection
Implementing best practices from government standards for cybersecurity can help protect citizens, businesses, and the country as a whole from the growing threat of cyberattack.
Roadmap for Prioritization
It provides a roadmap for organizations to prioritize their cybersecurity efforts, ensuring that they are focusing on the most critical risks.
Regulatory Alignment
Many organizations are required to comply with cybersecurity regulations and standards. Essential Eight provides a roadmap to meet these requirements and improve overall posture.
Multi-Framework Alignment
Cianaa integrates a multi-method approach using NZISM, ISO 27001, NIST 800-53 and PCI DSS to guide the audit process.
The Essential Eight Strategies
Eight crucial mitigation strategies, ranked for impact on the most common cyber security incidents.
Application Control
Ensure only trusted, approved applications can run on systems.
Patch Applications
Promptly apply security patches to third-party applications. Critical patch update in 48 hours.
Configure Microsoft Office Macro Settings
Disable or restrict macros in Office documents, especially from untrusted sources.
User Application Hardening
Harden user applications by turning off or removing risky features that aren’t needed.
Restrict Administrative Privileges
Limit admin accounts to only those who truly need them, and use the principle of least privilege.
Patch Operating Systems
Keep operating systems (Windows, macOS, Linux) up to date with the latest security patches.
Multi-Factor Authentication (MFA)
Require MFA for all users, especially for remote access and privileged accounts.
Perform Regular Backups
Perform daily or frequent backups of important data, software and configuration settings. Store backups securely offsite or offline.
The Auditor’s Philosophy
Scope & Objectives
The auditor works on the scope of the audit, establishes objectives and develops a plan for conducting the audit.
Identify Vectors
The auditors identify the people, processes and technologies in scope and identify potential attack vectors using design review and threat assessment.
Threat-Driven Method
Considering risks derived from the threat assessment, the auditors devise a robust method to evaluate each control sufficing due diligence.
Multi-Method Approach
We integrate a multi-method approach using NZISM, ISO 27001, NIST 800-53 and PCI DSS to guide the audit process. The approach makes the audit rigorous.
Control Effectiveness
The auditor looks into the effectiveness of the control to verify its presence to reduce the likelihood of threat and risks.
Evidence-Based Conclusion
The auditors collect and collate the evidence from different sources to conclude. The auditors take the necessary step to draw an evidence-based report.
