Security

Secured

Java is secured because:

• No explicit pointer
• Java Programs run inside virtual machine sandbox

• Classloader: adds security by separating the package for the classes of the local file system from those that are imported from network sources.
• Bytecode Verifier: checks the code fragments for illegal code that can violate access right to objects.
• Security Manager: determines what resources a class can access such as reading and writing to the local disk.

These security are provided by java language. Some security can also be provided by application developer through SSL, JAAS, Cryptography etc.
