Question 1

?What is the main advantage of using Go for API development compared to other programming languages

Accepted Answer

One of the main advantages of using Go for API development is its strong performance due to its compiled nature. Go's concurrency model allows for efficient handling of multiple requests, making it ideal for building high-performance APIs. Additionally, its simplicity and readability make it easier to maintain and scale APIs over time.

Question 2

? How can you secure a Golang API against common security threats

Accepted Answer

To secure a Golang API, you can implement the following measures:

Authentication: Use authentication mechanisms like OAuth 2.0, JWT, or API keys to ensure that only authorized users or applications can access your API.

Authorization: Implement role-based access control (RBAC) to define and enforce permissions for different users or roles.

Input Validation: Validate and sanitize user inputs to prevent SQL injection, XSS, and other security vulnerabilities.

Rate Limiting: Implement rate limiting to prevent abuse and protect against DDoS attacks.

HTTPS: Always use HTTPS to encrypt data transmitted between clients and the API, ensuring data privacy and integrity.

Error Handling: Implement proper error handling to avoid leaking sensitive information in error responses.

Security Headers: Set security headers like Content Security Policy (CSP) and Cross-Origin Resource Sharing (CORS) to mitigate common web security risks.

Regular Updates: Keep your dependencies and libraries up to date to patch known vulnerabilities.

Security Testing: Perform regular security assessments, including penetration testing and code reviews, to identify and address security issues.
