In today’s digital era, data is one of the most valuable assets for any organisation. However, with this value comes the responsibility to manage and protect data throughout its lifecycle. Effective data governance ensures data integrity, security, and compliance, particularly when it comes to data retention policies and mitigating the risks associated with data breaches.
With an increasing number of cyber incidents and regulatory requirements worldwide, businesses must implement robust data governance frameworks to prevent costly data breaches, comply with legal obligations, and maintain operational efficiency.
Data governance encompasses the policies, procedures, and standards that manage the availability, usability, integrity, and security of data within an organisation. It ensures that data is handled consistently and responsibly throughout its lifecycle—from creation and storage to usage and deletion.Implementing data governance across these stages ensures that data remains accurate, accessible, and secure, aligning with organisational goals and regulatory requirements.
Data retention policies define how long data should be kept and when it should be disposed of. These policies are crucial for several reasons:
Compliance: Many industries are subject to regulations that mandate specific data retention periods. Non-compliance can result in legal penalties.
Cost Management: Storing unnecessary data can lead to increased storage costs. Effective data retention policies help optimise storage resources.
Risk Reduction: Retaining data longer than necessary can expose organisations to risks, especially if the data is sensitive. Proper data disposal minimises the potential impact of data breaches.
For instance, a major airline's data breach in 2018 highlighted the risks of inadequate data retention practices. The airline stored payment card information for 95 days during a software test but continued collecting this data without a valid business reason, leading to a significant breach and a £20 million fine.
Data breaches can have devastating consequences, including financial losses, reputational damage, and legal liabilities. Effective data governance serves as a proactive measure to prevent such incidents through:
Access Controls: Ensuring that only authorised personnel can access sensitive data.
Data Encryption: Protecting data in transit and at rest to prevent unauthorised access.
Regular Audits: Monitoring data access and usage to detect and address vulnerabilities promptly.
By implementing these measures, organisations can significantly reduce the likelihood of data breaches and their associated impacts. With an optimised data governance strategy, businesses can improve productivity and ensure that employees have quick access to valuable data while eliminating clutter.
Recent Data Breach litigations in ANZ like Optus, Medibank, Latitude, Genea etc resulted in number of sensitive and personal records being exposed. In one instance The stolen data was leaked on the dark web, raising serious concerns about data protection laws and patient privacy rights. This incident highlights the need for stronger data retention and disposal policies to ensure that sensitive patient data is securely managed and deleted when no longer required.
The Office of the Australian Information Commissioner (OAIC) provides specific guidance on data retention, emphasising the importance of managing personal information in compliance with the Australian Privacy Principles (APPs).
In an age where data breaches and regulatory enforcement are increasing, businesses must prioritise data governance throughout the data lifecycle. Implementing a comprehensive data retention policy is key to reducing cybersecurity risks, legal liabilities, and operational inefficiencies.
By proactively managing data retention and disposal, organisations can safeguard sensitive information, ensure compliance, and enhance overall business resilience in today’s digital world.
