What is the Essential 8?
This resource explains the Essential 8, a set of key cybersecurity strategies recommended by the ACSC to protect organisations from cyber threats and enhance their overall security posture.
The Essential 8 is a set of baseline mitigation strategies recommended by the Australian Cyber Security Centre (ACSC) to help organisations protect themselves against various cyber threats. These strategies are designed to be the most effective measures to prevent cyberattacks and limit their impact. Implementing the Essential 8 can significantly reduce the risk of cyber incidents and enhance an organisation’s overall cybersecurity posture.
Understanding the Essential 8
The Essential 8 comprises eight key strategies that form the foundation of a robust cybersecurity framework. These strategies address common vulnerabilities and are designed to protect against a wide range of cyber threats.
1. Application Whitelisting
Objective: Ensure only approved applications can execute on systems.
- Description: Application whitelisting is a security measure that allows only trusted and approved applications to run on an organisation’s devices. By maintaining a list of authorised applications, organisations can prevent malicious software and unapproved programs from executing.
2. Patch Applications
Objective: Regularly update applications to protect against known vulnerabilities.
- Description: Patching applications involves applying updates and fixes to software to address security vulnerabilities. Regularly updating applications ensures that known security weaknesses are resolved, reducing the risk of exploitation by cyber attackers.
3. Configure Microsoft Office Macro Settings
Objective: Minimise the risk of macro-based malware.
- Description: Macros can be used to automate tasks in Microsoft Office, but they can also be exploited to deliver malware. Configuring macro settings to only allow macros from trusted locations or digitally signed macros helps prevent malicious code from running.
4. User Application Hardening
Objective: Reduce the attack surface of applications.
- Description: User application hardening involves configuring applications to minimise their vulnerabilities. This can include disabling or restricting features that are not needed, such as Flash, Java, and other browser plugins, to reduce potential entry points for attackers.
5. Restrict Administrative Privileges
Objective: Limit administrative privileges to reduce the risk of credential misuse.
- Description: Restricting administrative privileges involves limiting the number of users with administrative access to systems. By ensuring that only essential personnel have administrative rights, organisations can reduce the risk of misuse or compromise of these powerful accounts.
6. Patch Operating Systems
Objective: Regularly update operating systems to protect against known vulnerabilities.
- Description: Similar to patching applications, patching operating systems involves applying updates and fixes to the OS to address security vulnerabilities. Keeping operating systems up-to-date ensures that security weaknesses are patched, reducing the risk of exploitation.
7. Multi-Factor Authentication
Objective: Strengthen authentication processes to protect against credential theft.
- Description: Multi-factor authentication (MFA) adds an extra layer of security by requiring users to provide two or more verification factors to gain access to systems. This reduces the risk of unauthorised access even if credentials are compromised.
8. Regular Backups
Objective: Ensure data can be recovered in the event of a cyber incident.
- Description: Regular backups involve creating copies of critical data and storing them securely. In the event of data loss or a cyber incident, having up-to-date backups ensures that data can be restored, minimising disruption to business operations.
Benefits of Implementing the Essential 8
- Improved Security Posture: Reduces the risk of cyber incidents by addressing common vulnerabilities.
- Cost-Effective Protection: Provides a set of practical and cost-effective measures to enhance cybersecurity.
- Compliance: Helps organisations meet regulatory and compliance requirements related to information security.
- Business Continuity: Ensures that critical data can be recovered, minimising downtime and disruption.
- Trust and Reputation: Demonstrates a commitment to cybersecurity, enhancing trust with clients, partners, and stakeholders.
Implementing the Essential 8
To effectively implement the Essential 8, organisations should follow a structured approach:
- Assess Current Practices: Evaluate existing cybersecurity measures and identify gaps.
- Prioritise Strategies: Determine the most critical strategies based on the organisation’s specific risks and resources.
- Develop an Implementation Plan: Create a detailed plan outlining the steps, resources, and timelines for implementing each strategy.
- Train Employees: Educate staff on the importance of the Essential 8 and their roles in maintaining cybersecurity.
- Monitor and Review: Regularly assess the effectiveness of the implemented strategies and make necessary adjustments.
Conclusion
The Essential 8 provides a comprehensive and practical approach to enhancing cybersecurity for organisations of all sizes. By implementing these eight strategies, organisations can significantly reduce their risk of cyber incidents and protect their valuable information assets.
