Various groups and Java experts are trying to enhance the programming skills of Java developers for writing secure java applications. To meet the same purpose recently a new group of private-sector security experts have conducted a standardized exam to test developers' skills against the Java security standards.
 
To write a secure code in java you need to know various things besides having a deep knowledge of data hiding techniques. Just need to be aware of the following things:

1. Data handling techniques
2. User authentication rules
3. Access control
4. Capable administrator for session management and encryption services.

A secure Java application development is successful only if, it is written to meet both the quality and security purpose. A logical software design and a few guidelines driven from the experiences help to achieve a secure application.

There is no doubt that every programming language have its own weakness and strength and any developer can make a mistake while developing applications, but sometimes these mistakes become critical for the security purposes of an application and if such application is launched in the market it may cause a big loss or there could be a chance of data lost or stolen.
 
But programmers can achieve wrapping security into software applications easily with little efforts.

Following steps must be followed for a secure application development.

1. Logical software design
2. Proper validations
3. Well planed application development
4. Standardized security test

Every programming language have their own weakness and strength, so a little bit care and expertise in application development can keep your application safe from various attacks.
