What is the reverse process of serialization, whereby object data is recreated from the serialized data?

• A. Unvalidated Redirects and Forwards
• B. Deserialization
• C. Web Service Attack
• D. Cookie Snooping

Answer: (B)

Deserialization is the process of recreating an object from serialized data. Serialization turns an in-memory object into a format (such as JSON or a binary blob) that can be stored or transmitted. Deserialization reverses that, rebuilding the object with its original state so you can continue using it in your program. For example, you might serialize a user profile to JSON and later parse that JSON back into a user object. This step is where issues can arise if untrusted data is deserialized, potentially leading to security vulnerabilities like code execution. The other terms refer to redirects, web service attacks, and cookie access, which aren’t about reconstructing objects from serialized data.
