Java Security
By its nature, Java programs are written where security is absolutely paramount
- distributed systems, database connections, remote systems, and more.
So, security was one of the foundations upon which Java was built.
- The three pillars of security in Java include:
- Language design features, such as bounds checking on arrays, no pointer arithmetic, etc. Used incorrectly in other programming languages, these (mis) features allow hackers to see into your comptuer system.
- Access control that tells the code what it can and cannot do - such as write to a file from an applet.
- Code signing to authenticate the author of a program.
