Security Features in Java

2013-01-30

When Sun Microsystems developed the general-purpose yet object-oriented computer programming language, little was known that Java would garner a lot of attention someday. While the class-based and structured program renders an intriguing slew of ‘write once, run anywhere’ function, the multi-paradigm Java hogs the maximum spotlight for incorporating impressive security features.

Although other programming languages help control access to resources, Java endeavours to walk a mile extra to proffer enhanced and additional security characteristics for the developers. Whether you rifle through the reliable approaches to manage signature generation or seek for trustworthy control access to resources, the in-built Java Security features cover just about everything. Take a look over the security attributes rendered by the effectual yet convenient-to-use Java Development Kit – which can certainly benefit a variety of audiences.

End Users

Integrated with targeted, built-in security, Java unremittingly enables developers to seamlessly safeguard their program from malevolent issues (including viruses). The software, enriched with high security and protection features, also allows users to protect the privacy of their important files and data.

Developers

On the other hand, developers may benefit largely from Java Security features by embedding useful API methods into their programs. To provide a quick gist, the API framework basically allows developers to identify and incorporate their own permissions, policy implementations, security manager implementations, and cryptography service implementations into their respective programs. By integrating Java Security functions, developers could also benefit from the classes that are provided to help manage public/ private key pairs.

System Administrators

Concurrently, security features in Java play an important role in helping system administrators manage their database of keys and certificates. What’s more, Java Security ensures that system administrators find it simpler and easier to create digital signatures for JAR files and confirm the accuracy and legitimacy of such signatures and signed documents.

Since Java does not pick assistance from memory pointers explicitly, the programming language ensures to operate under a ‘safe location’ termed as the sand box. The integrated ‘Security Manager’ and ‘public key encryption system’ further ensures that the Java applications are carefully and safely transmitted over the internet in an extremely secure encrypted form.  There’s an unique byte-code verifier function as well that testes out the classes after loading.

Having discussed about some of the security features, it is evident that Java is a huge platform with well established security features and the recent security hole doesn’t seem to bring an end to the era of Java.
