Introduction
Data breaches involving sensitive customer Personally Identifiable Information (PII) are rising in Australia, posing significant risks to businesses and individuals. This alarming trend erodes consumer trust and highlights the need for more effective security measures. This article explores the key factors contributing to this increase in data breaches and discusses how businesses can better enhance their data governance to protect sensitive information.
The Rapid Digital Transformation of Businesses
The accelerated digital transformation of Australian businesses, fuelled by the COVID-19 pandemic, has led to an increased reliance on online services and remote work. While this has provided numerous benefits, it has also created new vulnerabilities for cybercriminals to exploit. Many companies, in their haste to adapt, have yet to be able to implement robust security measures to protect their sensitive data, leaving them more susceptible to breaches.
The Increase in Sophisticated Cyber Attacks
Cybercriminals are becoming more adept at employing advanced tactics to infiltrate networks and steal data. These sophisticated attacks include social engineering, ransomware, and zero-day exploits. Unfortunately, many Australian businesses need to be equipped to defend against these emerging threats, leaving their customer PII vulnerable to breaches.
Insufficient Employee Training and Awareness
Human error remains one of the leading causes of data breaches. In many cases, employees are unaware of the potential risks and may inadvertently expose sensitive data through actions like opening phishing emails or using weak passwords. In addition, many Australian companies need to prioritise cybersecurity training, leaving their staff ill-prepared to identify and prevent threats.
Inadequate Security Regulations and Compliance
While the Australian government has made strides in enhancing cybersecurity regulations, such as the Notifiable Data Breaches (#NDB) scheme under the Privacy Act, many businesses still need to comply. Some organisations may be unaware of their responsibilities, while others ignore them. This lack of adherence to cybersecurity regulations exacerbates the risk of data breaches.
Enhancing Data Governance and Security Measures
To address these challenges, Australian companies should prioritise the following strategies:
Implement a Robust Cybersecurity Framework and Embrace Zero Trust Security Model
Businesses should establish a comprehensive cybersecurity framework that includes regular risk assessments, vulnerability scanning, and security audits. This will enable them to identify potential weaknesses in their legacy and new IT ecosystem and address them before they can be exploited.
Embracing a zero-trust security model will help businesses ensure that no user or device can be trusted by default, requiring verification at every process stage. By implementing this approach, companies can significantly reduce the risk of unauthorised access to their sensitive data.
Invest in Employee Training and Awareness
Providing employees with the necessary tools and training to identify and respond to cyber threats can significantly reduce the risk of human error. Therefore, regular security awareness training should be a mandatory part of every company's cybersecurity strategy.
Strengthen Data Governance and Sensitive Data Management
Establishing strong data governance policies, combined with sensitive data discovery, tagging, masking, and data access policy management, is essential for protecting sensitive information. Businesses can minimise the risk of unauthorised access and data breaches by identifying, classifying, and managing sensitive data more effectively.
At the bare minimum – Mask your PII data
When Personally Identifiable Information (PII) is not masked, it becomes more vulnerable to data breaches. Data masking is a technique to obscure or replace sensitive data with fictional or anonymised versions, which helps protect PII from unauthorised access. Here are some reasons why unmasked PII can lead to more data breaches:
Exposure during data processing and analysis: Organizations often use PII to conduct data analysis or perform specific business processes. If PII is not masked during these processes, it can be exposed to unauthorised personnel, increasing the risk of data breaches.
Test and development environments: Data is often transferred between production and testing environments. If PII is not masked, developers and testers might have access to sensitive information, which can increase the risk of accidental exposure or data leakage.
Increased attack surface: Unmasked PII is a valuable target for cybercriminals, who can use this information for identity theft, financial fraud, or other malicious activities. When PII is stored and processed in its original form, it becomes an attractive target, increasing the likelihood of a data breach.
Data sharing with third parties: Companies often share data with third-party service providers, partners, or vendors for various purposes. If PII is not masked before sharing, it increases the risk of breaches due to weak security measures or unauthorised access at the third-party organisation.
Compliance violations: Many regulations, such as the ISO 27001 (#ISMS) from ISO International, the Information Security Manual and Essential Eight from the Australian Cyber Security Centre (#ACSC), General Data Protection Regulation (#GDPR) and the California Consumer Privacy Act (#CCPA), require organisations to protect PII. Failure to mask sensitive data may result in non-compliance, leading to potential data breaches and subsequent legal and financial penalties.
By masking PII, organisations can minimise these risks and ensure that sensitive information remains secure, even if a breach occurs. Masking techniques such as tokenisation, substitution, or data anonymisation can protect PII while maintaining its utility for business processes and analysis.
Ensure Compliance with Relevant Regulations
Australian businesses must familiarise themselves with the current cybersecurity regulations and take steps to ensure compliance. Adherence to these regulations helps protect sensitive customer data and demonstrates a commitment to consumer privacy and security.
Conclusion
The increasing prevalence of data breaches in Australia demands urgent attention from businesses and regulators alike. By taking proactive measures to secure customer PII, implementing robust cybersecurity strategies, and enhancing data governance, companies can safeguard their reputation and protect their customers' sensitive information from falling into the wrong hands. And even if a business suffers a breach for some reason, if all the PII data is known using a sensitive data discovery (#SDD) tool and masked, the damage is minimised to zero.
