What are the best practices for deserialization in programming?

When deserializing data, it's crucial to validate the input to prevent security vulnerabilities. Always use trusted sources.

Can you explain why input validation is so important?

Input validation helps prevent attacks like injection or data corruption by ensuring that only expected data formats are processed.

What libraries or tools do you recommend for safe deserialization?

Libraries like Jackson for Java or Newtonsoft.Json for .NET are great for safe deserialization, as they offer built-in security features.

Are there any common pitfalls to avoid during deserialization?

Yes, common pitfalls include deserializing untrusted data, failing to handle exceptions, and not using versioning for data formats.
