Assignment 5 Cloud-Native Application Security for a Tech Startup | CSIS 343 - Cybersecurity

4. Additional Security Considerations

4.1. Third-Party Dependencies: Evaluate third-party dependencies used within your serverless functions. Ensure that libraries and modules are kept up to date to patch vulnerabilities and vulnerabilities. 4.2. Cold Start Optimization: Optimize your serverless functions for cold starts. Minimize initialization time by reducing the size of deployment packages and leveraging caching mechanisms to speed up function invocations. 4.3. Logging Sensitive Data: Be cautious about logging sensitive data. Avoid logging sensitive information like passwords or personally identifiable information (PII). Implement log redaction or filtering to prevent data exposure. 4.4. Identity Management: Implement strong identity management practices. Use authentication and authorization mechanisms to ensure that only authenticated users or systems can trigger and access serverless functions. 4.5. Content Security Policy (CSP): Implement CSP headers to control the sources from which content can be loaded by your serverless applications. CSP helps mitigate cross-site scripting (XSS) attacks. 4.6. Application Layer Security: Focus on application layer security by implementing input validation, output encoding, and other security controls to protect against common web application vulnerabilities like SQL injection and cross-site scripting.
