What are the best practices for serialization security?

The best practices for serialization security include validating input data, using secure serialization formats, and avoiding deserialization of untrusted data.

Can you explain why validating input data is important?

Validating input data helps prevent attacks such as injection and ensures that only expected data types are processed, reducing vulnerabilities.

What secure serialization formats do you recommend?

I recommend using formats like JSON Web Tokens (JWT), Protocol Buffers, or XML with strict schemas, as they provide better security features.

How can I avoid deserialization of untrusted data?

To avoid deserialization of untrusted data, always use a whitelist approach for classes that can be deserialized and implement strict type checks.
