[&] What is the primary risk associated with insecure deserialization?
- The ability to execute arbitrary code -- Correct
- Difficulty in data storage
- Slow network transmission speeds
- Loss of data between systems

[&] What must a deserialization process ensure to prevent vulnerabilities?
- It should validate the integrity and authenticity of the incoming data -- Correct
- It needs to convert data into a human-readable format
- It should remove all spaces from the data
- It should compress data before processing

[&] What is the purpose of serialization in programming?
- To encrypt an object for secure transmission
- To ensure data integrity over a network
- To compress data to save space during transmission
- To convert an object into a format for easy storage or transmission -- Correct

[&] What is insecure deserialization?
- It occurs when serialized data cannot be deserialized
- It involves encrypting serialized data
- It is a vulnerability where untrusted data is deserialized without proper validation -- Correct
- It leads to data being permanently lost during transmission

[&] Why can the Pickle library in Python be dangerous in terms of deserialization?
- It ignores JSON and XML formats
- It can execute arbitrary code during deserialization -- Correct
- It compresses data without user intervention
- It automatically encrypts data
