Java security encompasses a robust framework of APIs, tools, and implementations designed to ensure secure application development and management. It spans areas such as cryptography, authentication, secure communication, and access control. Below are the key concepts and criteria for assessing Java security:

Core Security Features

Java's security architecture is built on principles like type safety, automatic memory management, and bytecode verification. These ensure that only legitimate code is executed, reducing vulnerabilities like memory corruption or unauthorized access. Access modifiers (private, protected, public, package-private) further restrict access to classes, methods, and fields, enhancing encapsulation and security.

The Java Development Kit (JDK) includes modules like java.security, javax.crypto, and javax.net.ssl, which provide foundational APIs for cryptography, authentication, and secure communication.
