What are the security features of the Java Virtual Machine?

The Java Virtual Machine (JVM) includes several security features such as the classloader, bytecode verification, and a security manager that enforces access controls.

How does the classloader contribute to security?

The classloader isolates classes from different sources, preventing unauthorized access and ensuring that only trusted classes are loaded.

Can you explain bytecode verification?

Bytecode verification checks the code for illegal operations, ensuring that it adheres to the JVM's safety rules before execution.

What role does the security manager play?

The security manager defines the security policies and permissions for Java applications, controlling what resources they can access.

Are there any common vulnerabilities in JVM?

Yes, common vulnerabilities include issues like deserialization attacks, improper access controls, and outdated libraries.
