Today, Java is driving quite $100 billion of business annually. If we take a look at the enterprise side, more than $2.2 billion are being spent by the enterprises in Java application server. There’s no denying that Java is employed extensively for developing Java enterprise applications reason being Security. Java brings some of the most fascinating features or benefits that are impossible to find in any other programming languages or platforms.
Security is an important aspect and Java’s security model is one amongst the key architectural features that make it most trusting selection once it involves developing enterprise-level applications. Security becomes vital once package is downloaded across network and dead regionally, and Java easily mitigates the security vulnerabilities associated with the projects or applications.
Java’s security model is intended to assist and protect users from hostile programs downloaded from some untrusted resource inside a network through “sandbox”. It permits all the Java programs to run within the sandbox solely and prevents several activities from untrusted resources together with reading or writing to the native disk, making any new method or maybe loading any new dynamic library whereas vocation a native methodology.
No use of pointers
C/C++ language uses pointers, which can cause unauthorized access to memory blocks once different programs get the pointer values. Unlike conventional C/C++ language, Java ne’er uses any quite pointers. Java has its internal mechanism for memory management. It solely provides access to the information to the program if has applicable verified authorization.
Exception handling concept
The conception of exception handling allows Java to capture a series of errors that helps developers to get rid of risk of crashing the system.
Defined order execution
All the primitives’ square measure outlined with a predefined size and every one the operations square measure outlined during a specific order of execution. Therefore, the code dead in several Java Virtual Machines won’t have a unique order of execution.
Byte code is another thing that makes Java more secure
Every time once a user compiles the Java program, the Java compiler creates a category file with Bytecode, that square measure tested by the JVM at the time of program execution for viruses and alternative malicious files.
Tested code re-usability
The Java object encapsulation provides support for the conception of “programming by contract”. This allows the developers to re-use the code that has already been tested while developing Java enterprise applications.
Access Control functionality
Java’s access-control functionality on variables and methods within the objects offer secure program by preventing access to the vital objects from the untrusted code.
Protection from security attacks
It allows developers to declare classes or methods as FINAL. We all know that any class or method declared as final can’t be overridden, which helps developers to protect code from security attacks like creating a subclass and replacing it with the original class and override methods.
Garbage collection mechanism
Garbage collection mechanism aids additional to the protection measures of Java. It provides a clear storage allocation and recovering unutilized memory instead of deallocating memory through manual action. It will help developers to make sure the integrity of the program throughout its execution and avoids any JVM crash due to incorrect freeing of memory.
Type-safe reference casting in JVM
Whenever you employ associate object reference, the JVM monitors you. If you try to cast a reference to a different type, it will make the cast invalid.
Apart from of these, structured error handling contributes lots to the protection model of Java by serving to boost the lustiness of the programs. The above arguments definitely prove that the projects developed in Java are more secure as compared to the other programming language. However, it is the responsibility of the developers to follow some best practices while developing enterprise-level Java applications.
