How to reduce the risk of data breaches and ensure compliance with Australian data protection regulations
Protecting Data in Transit
1. Encryption:
- Encryption protocols like TLS (Transport Layer Security) are used to encrypt
data as it moves between systems or over the internet. This ensures that even if
data is intercepted, it remains unreadable to unauthorised users. - Implement VPNs (Virtual Private Networks) to create secure, encrypted data transmission tunnels
2. Secure Communication Channels
- Use secure communication channels such as HTTPS for websites to encrypt
data exchanged between the client and server. - Utilize secure email protocols like S/MIME (Secure/Multipurpose Internet Mail Extensions) for encrypting email content
3. Authentication and Authorization:
- Implement strong authentication mechanisms to verify the identity of users and
devices before allowing data transmission. - Use role-based access control (RBAC) to ensure that only authorised personnel
can access sensitive data during transmission
4. Integrity Checks:
- Implement data integrity checks using cryptographic hash functions to ensure
data has not been tampered with during transmission
5. Network Security:
- Use firewalls, intrusion detection/prevention systems (IDS/IPS), and antimalware tools to protect the network infrastructure from unauthorised access
and threats. - Segment networks to limit the spread of potential attacks and to isolate sensitive
data
Protecting Data at Rest
1. Encryption:
- Use strong encryption standards (e.g., AES-256) to encrypt sensitive data stored on disks, databases, and other storage devices. This ensures that data remains protected even if physical storage devices are lost or stolen
2. Access Controls:
- Implement strict access control policies to limit who can access sensitive data. Use multi-factor authentication (MFA) for an additional layer of security.
- Regularly review and update access permissions to ensure only authorised users
have access to data
3. Data Masking and Anonymization:
- Use data masking techniques to obfuscate sensitive information in non production environments.
- Apply data anonymisation methods to remove personally identifiable
information (PII) from datasets when it’s not necessary for business operations.
4. Regular Audits and Monitoring:
- Conduct regular security audits and vulnerability assessments to identify and mitigate potential risks.
- Implement continuous monitoring solutions to detect and respond to
unauthorised access or anomalous activities in real time.
5. Physical Security:
- Ensure physical security measures such as locked server rooms, access control systems, and surveillance cameras are in place to protect physical storage
devices. - Implement clean desk policies to protect sensitive print copies.
6. Data Backup and Recovery:
- Regularly back up data to secure offsite locations. Ensure backups are encrypted
and test the recovery process periodically to ensure data can be restored in case
of an incident.
