Key Actions:
✔ Adhere to the Australian Privacy Principles (APPs) when collecting data.
✔ Ensure all stored and transmitted data is encrypted (using AES-256 and TLS 1.3).
✔ Secure explicit user consent prior to processing personal information.
Weak login credentials represent a significant attack vector. Implementing Multi-Factor Authentication (MFA) and role-based access control (RBAC) can significantly diminish unauthorized access.
Your application’s authentication system should be robust. There are various methods to strengthen the authentication process. Multi-Factor Authentication (MFA) is a widely adopted method to enhance security. Numerous MFA services are available today, including Google Authenticator and SMS-based one-time passwords (OTPs).
On both iOS and Android platforms, you can utilize Face ID and fingerprint scanners. Additionally, enforce minimum password length requirements and a combination of character types. This approach complicates unauthorized access attempts through brute force or guessing.
Key Actions:
✔ Implement MFA (SMS, biometrics, authenticator applications).
✔ Utilize OAuth 2.0 or JWT tokens to ensure secure sessions.
✔ Enforce password policies (minimum of 12 characters, no reuse).
Unencrypted data presents a significant risk for hackers. End-to-end encryption (E2EE) guarantees the safety of data both during transmission and while stored.
Key Actions:
✔ Utilize AES-256 for data at rest.
✔ Implement TLS 1.3 to secure network communications.
✔ Regularly rotate encryption keys.
APIs are key targets for cyberattacks. Unprotected APIs can result in data breaches, DDoS attacks, and violations of compliance regulations.
In the development of mobile applications, it is essential that the communication between the application and external services is secure; this includes APIs or servers. Ensure that all API requests from your application utilize HTTPS instead of HTTP, even when interacting with local or development servers. If sensitive information must be transmitted, confirm that it is encrypted using robust algorithms prior to transmission.
Key Actions:
✔ Employ OAuth 2.0 / JWT for authentication APIs.
✔ Introduce rate limiting to thwart brute-force attacks.
✔ Perform API penetration testing prior to deployment.
Security is not a one-off endeavor—continuous testing identifies vulnerabilities before they can be exploited by hackers.
Regular security assessments are the most effective method to uncover potential weaknesses. By proactively testing your application, you can significantly decrease the chances of a security breach.
We strongly advise conducting manual penetration testing. Automated tools often lack effectiveness. Rather than depending solely on automated testing tools, integrate both manual and automated testing to comprehensively evaluate your application more efficiently.
