What’s keeping you up at night? Is it the constant worry about cyber threats hiding in the corners of our digital world? But here’s the big question: Do you have the right tools to fight back?
In this cybersecurity battle, your secret weapons are frameworks. Not just any frameworks, though – we’re talking about the ASD Essential 8, developed here in Australia, and the internationally renowned NIST Cybersecurity Framework (CSF).
But which one is right for your organisation? Join us as we explore these frameworks, comparing their strengths and differences and helping you make an informed decision that could be the cornerstone of your cybersecurity strategy.
Introduction to Cybersecurity Frameworks
Cybersecurity frameworks are structured guidelines designed to help organisations assess and improve their security posture. They provide a systematic approach to identifying, protecting against, detecting, responding to, and recovering from cyber threats. These frameworks are essential because they offer a common language and set of standards for addressing cybersecurity risks, enabling organisations to align their security efforts with industry best practices.
The ASD Essential 8 and NIST CSF are two widely recognised frameworks that have gained popularity in recent years. The ASD Essential 8, developed by the Australian Cyber Security Centre, focuses on eight key strategies to mitigate cybersecurity incidents, serving as a practical guide for defending against cyber threats. On the other hand, the NIST CSF, created by the U.S. National Institute of Standards and Technology, provides a more comprehensive approach to managing cybersecurity risks across an entire organisation, making it a versatile tool for information security risk management.
Overview of the ASD Essential Eight
The ASD Essential 8 is a prioritised set of mitigation methods that can assist organisations in defending their systems from various cyber threats. These methods, created by the Australian Signals Directorate- a key agency within the Australian government – and maintained by the Australian Cyber Security Centre, are based on the ASD’s expertise in reacting to cybersecurity incidents and conducting vulnerability assessments across numerous organisations.
The set of eight security strategies that make up the Essential 8 are:
- Application Control: This strategy prevents the execution of unapproved or malicious programs. It’s important because it significantly reduces the attack surface by ensuring that only trusted applications can run.
- Patch Applications: Regularly updating applications addresses known vulnerabilities. This is vital as many cyber attacks exploit known software flaws that have available patches.
- Configure Microsoft Office Macro Settings: By blocking untrusted macros, organisations can prevent a common attack vector. Macros are often used to deliver malware through seemingly innocent documents.
- User Application Hardening: This involves configuring web browsers and other applications for maximum security. It minimises vulnerabilities in commonly used applications that attackers could exploit.
- Restrict Administrative Privileges: Limiting administrative access based on user duties reduces the potential impact of a successful attack. It’s a key principle of least privilege.
- Patch Operating Systems: Similar to application patching, this ensures that operating systems are up-to-date with the latest security fixes.
- Multi-factor Authentication: This strengthens user authentication by requiring multiple forms of verification. It’s crucial to prevent unauthorised access even if passwords are compromised.
- Regular Backups: Maintaining the ability to restore systems and data is essential for recovery from ransomware and other destructive attacks.
The ASD Essential 8 primarily focuses on preventative measures to reduce the attack surface and make it harder for adversaries to compromise systems. It’s designed to be straightforward to implement and provides a clear starting point for organisations looking to improve their cybersecurity posture.

Overview of the NIST CyberSecurity Framework
The NIST Cybersecurity Framework was developed in response to Executive Order 13636, which called for a standardised security framework for critical infrastructure in the United States.
While developed in the United States, the NIST Cybersecurity Framework has gained international recognition and adoption, including in Australia. Its comprehensive approach to cybersecurity risk management has made it a valuable tool for organisations worldwide.
The NIST CSF is built around five core functions:
- Identify: Develop an organisational understanding of how to manage cybersecurity risk to systems, people, assets, data, and capabilities.
- Protect: Develop and implement appropriate safeguards to ensure the delivery of critical services.
- Detect: Develop and implement appropriate activities to identify the occurrence of a cybersecurity event.
- Respond: Develop and implement appropriate activities to take action regarding a detected cybersecurity incident.
- Recover: Develop and implement appropriate activities to maintain resilience plans and restore any capabilities or services that were impaired by a cybersecurity incident.
These functions are further broken down into categories and subcategories, providing a comprehensive set of outcomes and references.
The NIST CSF also includes implementation tiers that describe the degree to which an organisation’s cybersecurity risk management practices exhibit the characteristics defined in the framework. These tiers range from Partial (Tier 1) to Adaptive (Tier 4).
Additionally, the framework uses profiles to help organisations align their cybersecurity activities with business requirements, risk tolerances, and resources. These profiles can be used to identify opportunities for improving cybersecurity posture by comparing a “Current” Profile with a “Target” Profile.
