Strategies to mitigate cyber security Incidents in Australia

Table of Contents

Cybersecurity incidents have become a growing concern for individuals, businesses, and governments worldwide, including Australia. The Australian Bureau of Statistics (ABS) reported that the frequency and impact of cyber incidents have escalated significantly. In FY22, 22% of Australian businesses experienced cybersecurity incidents, compared to just 8% in FY20. These incidents have resulted in various consequences, including loss of time, service downtime, and decreased staff productivity.

Mitigating cyber security incidents requires a comprehensive approach encompassing proactive and reactive measures. It involves identifying vulnerabilities, implementing risk mitigation strategies, and promptly responding to incidents when they occur. At the forefront of Australia’s cybersecurity efforts, the Australian Signals Directorate (ASD) plays a pivotal role in safeguarding the nation’s digital assets.


Australian Signals Directorate (ASD) Strategies for Cybersecurity Risk Mitigation

The ASD has developed strategies to mitigate cybersecurity incidents and protect critical national infrastructure. These strategies, known as the TOP 4 mitigation strategies, include application whitelisting, patching applications, patching operating systems, and restricting administrative privileges. Implementing the Top 4 strategies to mitigate targeted cyber intrusion enhances an organisation’s cyber resilience from new threats.


Application Whitelisting

This strategy allows only approved and trusted applications to run on a computer system while blocking or preventing the execution of unauthorised or malicious software. This helps protect against the execution of malicious software and unapproved applications, which are a common source of cybersecurity threats.


Patching Applications

Patching applications, in the context of cybersecurity, refers to the practice of regularly applying updates and fixes (known as patches) to software applications. These updates are provided by the software vendors to address security vulnerabilities, improve functionality, and bug fixes.


Patching Operating Systems

Just like patching applications, it’s crucial to regularly apply security patches and updates to the underlying operating systems of computers and servers. Unpatched operating systems can be an easy target for attackers looking to exploit known vulnerabilities.


Restricting Administrative Privileges

Limiting administrative privileges is crucial for reducing the risk of unauthorised access and privilege escalation within an organisation. This minimises the potential impact of insider threats and the spread of malware and also limits access to cybercriminals.

ACSC Essential Eight Cybersecurity Risk Mitigation Strategies

ACSC Essential 8 is a set of cybersecurity strategies developed by the Australian Cyber Security Centre (ACSC) to help organisations protect their computer systems and networks from cyber threats. These strategies are designed to mitigate a range of cyber risks and enhance overall security.

The ACSC Essential 8 strategies to mitigate cyber security risks cover various aspects of cybersecurity, including application whitelisting, patching applications, patching operating systems, and restricting administrative privileges, which are also included in the ASD Top 4 Mitigation Strategies, and the other four are user application hardening, multi-factor authentication, configure Microsoft Office macros and daily backups.


User Application Hardening

This strategy focuses on ensuring that common user applications like web browsers and PDF viewers are securely configured. Secure configurations can help mitigate potential security risks associated with these applications, such as drive-by downloads and browser-based attacks.


Multi-Factor Authentication (MFA)

MFA adds an extra layer of security to user accounts. It typically involves requiring users to provide two or more authentication factors. MFA helps prevent unauthorised access, even if someone has acquired the user’s password.


Configure Microsoft Office macros

Microsoft Office macros can be used to deliver malware. This strategy involves configuring Office applications to block macros that originate from the internet or other untrusted sources while allowing macros from trusted sources to reduce the risk of macro-based attacks.


Daily Backups

Regularly backing up critical data and verifying the integrity of those backups is essential for data recovery in case of data loss, corruption, or ransomware attacks. Daily backups help ensure that recent data can be restored, minimising potential downtime and data loss in the event of a cybersecurity incident.


How to Enhance Your Organisation’s Cybersecurity Posture (Importance of a Strong Security Posture)

A strong security posture refers to an organisation’s overall security approach and ability to effectively prevent and respond to cyber threats. It involves a combination of technical controls, security policies, and employee awareness. Enhancing an organisation’s security posture is essential to minimise the impact of cyber security incidents and protect sensitive information from unauthorised access.


Implementing Best Practices for Cybersecurity Risk Mitigation

Implementing the best cyber security risk mitigation practices is crucial in maintaining a solid security posture. These practices include regularly updating and patching software, using strong and unique passwords, enabling multi-factor authentication, conducting regular backups, and encrypting sensitive data. Organisations can fortify their defences against potential cyberattacks by adhering to these best practices.
