The GRC buyer’s guide for 2025: Building resilience with AI-powered, federated solutions


What is ASD Essential 8?

The ASD Essential 8 is a set of cybersecurity practices developed by the Australian government to help organizations defend against common cyber threats. It provides a prioritized list of actions to improve security, such as patching software, using multi-factor authentication, restricting administrative privileges, and applying application whitelisting. By following these steps, organizations can strengthen their defenses and reduce the risk of cyber incidents.

Who must comply with ASD Essential 8?

While compliance with the ASD Essential 8 is not legally required, it is highly recommended for all Australian businesses, government agencies, and entities. Adopting Essential 8 helps organizations minimize cyber risks and improve their overall security posture. The framework is designed to address widespread cyber threats and establish strong security measures across various areas, including user access, application control, and regular backups. Aligning with Essential 8 helps organizations enhance their cybersecurity maturity and stay prepared to respond effectively to potential security breaches.

Key components of ASD Essential 8

The ASD Essential 8 framework, developed by the Australian Signals Directorate (ASD), provides a set of cybersecurity controls to help organizations protect themselves against a wide range of cyber threats. Each component plays a vital role in reducing vulnerabilities and ensuring resilience against attacks.

1. Multi-factor Authentication (MFA)

Multi-factor Authentication (MFA) requires users to provide two or more verification factors to gain access to systems, networks, or applications. These factors typically include something you know (password), something you have (security token or mobile device), and something you are (biometric authentication like fingerprints or facial recognition).
  • Why it’s important: MFA adds an extra layer of security beyond just a password, making it more difficult for cybercriminals to gain unauthorized access, even if they have stolen login credentials.
  • Benefit: Helps prevent unauthorized access to sensitive data and systems, reducing the risk of data breaches.

2. Application control

Application control involves restricting the execution of unauthorized applications within an organization’s environment. This is achieved by creating a whitelist of trusted applications, while blocking any other software that is not approved or required.
  • Why it’s important: Many cyberattacks, such as malware and ransomware, rely on executing malicious applications to infect systems. By allowing only trusted software, organizations can block the execution of harmful applications.
  • Benefit: Helps prevent malware and ransomware attacks, which often exploit vulnerabilities in unapproved applications.

3. Patching applications & operating systems

Patching refers to the process of updating software and operating systems to fix known vulnerabilities. These updates often include security patches that address bugs and flaws that could be exploited by attackers.
  • Why it’s important: Cybercriminals often target unpatched vulnerabilities in software to launch attacks. Regularly applying patches reduces the risk of exploitation by known threats.
  • Benefit: Protects systems from being exploited by attackers who target outdated software with unpatched security holes.

4. Restricting admin privileges

Restricting administrative privileges involves limiting access to critical systems and data to only those who absolutely need it. Users with admin rights have higher levels of control, so restricting their number reduces the risk of accidental or malicious changes to systems.
  • Why it’s important: Admin accounts have the ability to modify, delete, or install software and configurations that can affect the entire system. Limiting these privileges helps minimize the impact of a compromised account.
  • Benefit: Reduces the potential damage of an internal or external attack by preventing unauthorized changes and system access.

5. Daily backups

Daily backups involve regularly creating copies of important data and system configurations. These backups are stored in secure locations to ensure data can be recovered in the event of an attack, hardware failure, or disaster.
  • Why it’s important: In the case of data loss due to cyberattacks like ransomware, having recent backups allows organizations to recover quickly without paying a ransom or losing critical information.
  • Benefit: Ensures that business continuity is maintained, even if systems are compromised, by enabling rapid data recovery.

6. User application hardening

User application hardening involves securing applications used by employees, such as web browsers, office software, and email programs, by disabling unnecessary features that could be exploited by attackers.
  • Why it’s important: Many user applications come with features that are not necessary for daily tasks but could present security risks (e.g., macros in Microsoft Office). By hardening these applications, organizations reduce the attack surface that cybercriminals can exploit.
  • Benefit: Reduces the potential for vulnerabilities in user applications, lowering the chances of successful exploitation by attackers.
