14. Security in Java (Cryptography & Access Control)
The chapter delves into the essential aspects of security in Java, focusing on cryptography, authentication, access control, and the corresponding APIs provided by the Java framework. Key components such as the Java Cryptography Architecture (JCA), Java Authentication and Authorization Service (JAAS), and the SecurityManager illustrate how Java supports secure application development. Furthermore, best practices in Java security are emphasized to mitigate risks associated with data breaches and unauthorized access.

What we have learnt
- Java provides robust frameworks for security through APIs like JCA for cryptography and JAAS for authentication.
- Access control in Java is managed by the SecurityManager, which utilizes policy files to govern resource access.
- Best practices in Java security include using cryptographically strong random values and keeping software updated to prevent vulnerabilities.
Key Concepts
- -- Java Cryptography Architecture (JCA)
- A framework that provides a set of cryptographic functionalities including key management, encryption, and digital signatures.
- -- SecurityManager
- A component that manages access control to system resources using defined policies.
- -- Java Authentication and Authorization Service (JAAS)
- A framework that enables applications to authenticate users and enforce access control based on user roles.
