Security features in Java programming are crucial, including: Access control: Control access rights to different resources through the rights management module. Cryptography: Provides powerful encryption and decryption capabilities to protect data security. Input verification: Use tools to verify user input and prevent malicious attacks. Practical example: Use these features to build a secure login system that hashes passwords, validates input, and controls access.
Secure Programming in Java: Leveraging Java’s Built-in Security Features
In modern software development, security is crucial. The Java language provides a range of built-in security features that can help developers protect their applications from attacks. This article will explore Java's security features and show how to use them through practical examples.
Access Control
Java implements access control through the permission management module, which allows developers to specify access to different resources (such as files, data structures, methods) Required permissions. Access permissions can be set for the class through the following code:
1 2 3 4 |
|
Cryptography
Java provides a powerful cryptography API for encrypting and decrypting data. The following code demonstrates how to encrypt and decrypt a string using the AES algorithm:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 |

Input Validation
It is important to validate user input to prevent malicious attacks. Java provides some tool classes to help with input validation, such as:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |

Practical case: Secure login system
Consider an application that requires users to log in to the system. We can use Java's security features to achieve secure login:
By leveraging Java’s built-in security features, developers can build secure and reliable applications that protect user data and systems from threats.
