Java Security Manager

A security feature in Java that enforces access control policies for applications.

Understanding:

The Java Security Manager is a security mechanism in Java that enforces access control policies to restrict what actions Java applications can perform.

Common Applications and Use Cases:

Preventing Unauthorized File Access – Restricts reading/writing sensitive files.
Restricting Network Connections – Controls which hosts an application can communicate with.
Sandboxing Java Applications – Protects against malicious or untrusted code execution.

Best Practices and Security Considerations:

Define Fine-Grained Security Policies – Enforce strict permissions.
Use the Latest Java Versions – Older versions have known bypasses.
Monitor and Audit Security Manager Logs – Detects policy violations.
