What Australian regulations affect REST API development?

The Privacy Act 1988 and Australian Privacy Principles (APPs) are fundamental for any API handling personal information. Financial services must comply with APRA CPS 234 for information security. The Notifiable Data Breaches scheme requires reporting of eligible breaches within 72 hours. Critical infrastructure providers face additional requirements under the Security of Critical Infrastructure Act. Healthcare APIs must consider My Health Records Act requirements.

How do we implement OAuth 2.0 for Australian compliance?

OAuth 2. 0 implementation for Australian compliance requires specific configurations beyond standard setup. Use the authorisation code flow with PKCE for public clients, implement short-lived access tokens (typically 15-60 minutes), and enforce refresh token rotation. Store tokens securely using encryption at rest, never in browser local storage. Implement consent screens that clearly explain data usage per APP 5 requirements. Include scope limitations aligned with data minimisation principles.

What encryption standards are required for Australian APIs?

Australian APIs must implement TLS 1. 3 as the minimum encryption standard, with TLS 1. 2 acceptable only for legacy system compatibility. Use AES-256 for data encryption at rest, particularly for personal and sensitive information. Implement perfect forward secrecy through ECDHE key exchange. Certificate pinning adds extra security for mobile applications. For highly sensitive data, consider implementing field-level encryption within API payloads.

How should we handle API rate limiting for Australian businesses?

Implement tiered rate limiting based on authentication levels and client types. Unauthenticated requests might receive 100 requests per hour, authenticated users 1000 per hour, and premium clients 10000 per hour. Use sliding window algorithms rather than fixed windows to prevent burst attacks. Implement geographic rate limiting to protect against international threats while ensuring legitimate Australian traffic flows freely.

What logging is required for API compliance in Australia?

Comprehensive logging is essential for Australian compliance, particularly under the Notifiable Data Breaches scheme. Log all authentication attempts (successful and failed), API endpoint access with timestamps and client identifiers, data modifications with before/after states for critical fields, and any security events or anomalies. Retain logs for minimum periods specified by relevant regulations (typically 7 years for financial data).

How do we ensure API data sovereignty compliance?

Data sovereignty requires careful API architecture design for Australian businesses. Implement geo-fencing to ensure data remains within Australian borders when required. Use Australian-hosted cloud regions (AWS Sydney, Azure Australia East/Southeast) for data storage and processing. Configure CDNs to cache only non-sensitive data internationally. Implement data residency headers in API responses to verify processing location.

What API testing is needed for security compliance?

Security testing must cover multiple layers to ensure compliance. Conduct OWASP API Security Top 10 assessments quarterly, focusing on broken authentication, excessive data exposure, and injection vulnerabilities. Perform penetration testing annually or after significant changes, using PTES or OWASP methodologies. Implement automated security scanning in CI/CD pipelines using tools like OWASP ZAP or Burp Suite. Test rate limiting effectiveness under load conditions.

What are the critical REST API security practices for Australian businesses?

Australian businesses must implement OAuth 2.0/JWT authentication, TLS 1.3 encryption, rate limiting, input validation, and comprehensive audit logging. APIs handling personal data must comply with Privacy Act 1988 and APPs, while financial APIs need APRA CPS 234 compliance.

Australian businesses struggle to balance API performance with stringent security requirements while ensuring compliance with local data protection regulations and international standards.

Implement a comprehensive API security framework that addresses authentication, encryption, rate limiting, and monitoring while ensuring full compliance with Australian privacy and data protection requirements.
