Common Security Mistakes

Common Security Mistakes

Learning from common mistakes helps avoid repeating them:

Storing Sensitive Data Insecurely: Developers often store passwords, API keys, or personal data in plain text within the application or in easily accessible storage locations. Always encrypt sensitive data and use platform-provided secure storage mechanisms.

Weak Network Security: Failing to implement proper SSL/TLS, not validating certificates, or transmitting sensitive data over unencrypted channels leaves applications vulnerable to network attacks. Always use HTTPS and implement certificate pinning for sensitive applications.

Insufficient Input Validation: Mobile apps often trust user input without validation, leading to injection attacks and data corruption. Validate all input on both client and server sides, treating all external data as potentially malicious.

Poor Authentication Implementation: Weak password requirements, lack of multi-factor authentication, or storing credentials insecurely compromises user accounts. Implement strong authentication using platform capabilities and industry best practices.
