Privacy and Data Governance Reforms

The recent reforms in privacy and data governance emphasize transparency and accountability. Organizations are now required to demonstrate their data handling processes clearly and are subject to regular audits to ensure compliance with the new standards.

Preventative Measures and Best Practices

Cyber Security Hygiene and Credential Management

Practising good cybersecurity hygiene is foundational to preventing breaches. Patch your systems regularly, implement multi-factor authentication (MFA), and enforce password best practices. Regular penetration testing of web-facing applications helps identify and remedy vulnerabilities before they are exploited.

Implementing Robust Data Protection Protocols

Encryption is a key measure to protect stored and transmitted data. Organizations must critically assess their need to store sensitive data and apply robust security measures for any data retained. A well-exercised cyber incident response plan is crucial for effective mitigation.

Lessons from Recent Breaches

Learning from past incidents is vital. Implementing ASD's Essential Eight and adhering to the Open Web Application Security Project (OWASP) Top Ten Proactive Controls can significantly enhance security postures. Additionally, maintaining a cyber security incident register can assist with ensuring that appropriate remediation activities are undertaken.

The Role of Public Awareness and Reporting

Increased Reporting and Public Scrutiny

Increased reporting of cyberattacks has become a notable trend, particularly following breaches at major corporations. This heightened awareness and responsiveness are crucial for improving overall cyber security. Public scrutiny not only holds companies accountable but also encourages better security practices across industries.

Educational Initiatives by Regulatory Bodies
