In the current era of advanced technology, cyber threats have become a major concern for businesses of all sizes. As a result, it has become increasingly important for organisations to have robust cyber security frameworks in place. Essential Eight is a recognised framework recommended by the government in Australia, and CIS Controls is one of the most globally recognised frameworks in this domain. These frameworks offer structured guidance to organisations to strengthen their defences against cyber attacks.
In this article, we will explore the details of these frameworks. We will break down their components, practicality, and impact on modern cyber security practices. By doing so, we will better understand how these frameworks can help organisations protect their important assets from cyber threats.
Understanding the Essential Eight and CIS Controls:
Essential Eight:
Like many other countries, Australia faces an increasing number of cyber threats that can compromise sensitive data and disrupt operations. To strengthen the nation’s Cyber Security resilience, the Australian Cyber Security Centre (ACSC) has identified the Essential 8 Controls as fundamental strategies to mitigate Cyber Security risks.
The Essential 8 Controls are a comprehensive set that forms the foundation for a robust Cyber Security framework, ensuring the protection of an organisation’s critical systems and sensitive data.
Why Does Your Company Need the Essential 8 Controls?
Protection: The Essential 8 Controls cover a broad spectrum of security measures, including application whitelisting, patching applications, configuring Microsoft Office macro settings, and many more. Implementing these controls ensures that your organisation has a multi-layered defence strategy.
Adaptation to Changing Threats: Cyber threats constantly evolve. The Essential 8 Controls provide a flexible framework that allows your organisation to adapt and respond effectively to emerging threats.
Compliance and Regulations: Many industries are subject to stringent data protection and Cyber Security regulations. By adopting these controls, your company can demonstrate compliance with legal and regulatory requirements.
CIS Controls:
The CIS Controls, formerly known as the SANS Critical Security Controls, are a set of best practices developed by the Centre for Internet Security (CIS) to help organisations defend against and respond to cyber threats. These controls provide a prioritised framework of cyber security measures that effectively prevent and mitigate cyber-attacks.
There are 20 CIS Controls organised into three categories:
Basic Controls: These are fundamental security measures that organisations should implement first. They focus on basic cyber hygiene practices such as inventory and control of hardware assets and continuous vulnerability management.
Foundational Controls: These controls build upon the basic controls and provide additional layers of security. They include areas such as secure configuration for hardware and software, continuous vulnerability assessment and remediation, controlled use of administrative privileges, and maintenance, monitoring, and analysis of audit logs.
Organisational Controls: These controls involve strategic cyber security management and governance practices. They include areas such as security awareness and training, application software security, incident response and management, penetration tests and red team exercises, and security metrics.
The CIS Controls are designed to be flexible and scalable, allowing organisations of all sizes and industries to tailor them to their specific cyber security needs. By implementing CIS Controls, organisations can improve their overall cyber security posture and better protect their assets, data, and systems from cyber threats.
Comparing the Two:
While the Essential Eight and CIS Controls share a common objective of fortifying organisations against cyber threats, they diverge in their approach, scope, and granularity of recommendations.
Overlap and Distinctions:
There is a significant overlap between the Essential Eight and CIS Controls, especially in foundational cyber security measures such as patch management, application control, and user authentication.
While the Essential Eight offers a concise and pragmatic set of strategies tailored to mitigate common cyber threats, the CIS Controls adopt a more granular approach, delineating a hierarchical framework comprising Basic, Foundational, and Organisational controls.
The Essential Eight’s focus on practical mitigation strategies resonates with organisations looking for tangible outcomes, while the CIS Controls’ comprehensive framework appeals to entities aiming for a more nuanced understanding of cyber security risk management.
Scalability and Flexibility:
The modular structure of the Essential Eight allows organisations to scale their cyber security initiatives according to their changing needs and risk profiles.
On the other hand, the tiered hierarchy of the CIS Controls accommodates organisations of different sizes and levels of maturity, providing a roadmap for advancing from basic cyber security practices to advanced threat detection and incident response capabilities.
By delineating the nuances between the Essential Eight and CIS Controls, organisations can make informed decisions regarding the most suitable framework for their cyber security needs. Let’s continue expanding on the comparison to provide a comprehensive analysis.
