Unlike the technology firms, banks and financial institutions are very conservative about deciding the programming language to develop applications. There are also many instances when banks have to compensate customers to minor defects in their applications. But a number of reports have highlighted that Java is being used widely as a high performance programming language for building a wide variety of mission critical financial applications. There are also several reasons why Java is considered by many organizations for creating banking applications.

Java for E-Commerce business - Is it good?
The computing platform, Java is independent, secure as well as robust, ensuring high performance. This network savvy, portable as well as architecturally neutral language uses automatic memory management. The programming language can be used to develop ecommerce applications easily due to the several feature sets that make it an effective ecommerce platform. It is platform-independent, network-aware, multi-threaded as well as object-oriented which make it really flexible. Near about any platform can be used for its running. Some of the reasons that have made it suitable for ecommerce business are discussed here.
Java 2 Enterprise Edition- Also known as J2EE, it has proved to be a revolutionary influence in the arena of e-commerce. Strong server side application can be build through the robust and solid solution of J2EE. The technology is fully-able and is extremely beneficial as a development tool. Some of the tools included in it that helps in this respect are Servlets, JSPs or Java Server Pages, Enterprise JavaBeans or EJB, JNDI or Java Naming and Directory Interface, JDBC or Java Database Connectivity, JTA, JMS along with Java Mail.
No programmatic configuration of navigation- To set navigation, a specified pattern has to be implemented which can be really complicated as well as a time-consuming process. But when you are using JSF, all the complicated procedures can be avoided altogether. The framework handles the navigation entirely. All that is needed is to associate page views, URL patterns as well as logical outcomes together by using Faces configuration file. Developers can also follow another method- using the implicit navigation feature of JSF 2.0 that forwards requests automatically to a view having the same name as that of the requested URL pattern.
Good templating support- The Facelets technology can be used for templating and it helps maximize markup reuse so that redundancy in page views can be reduced. It also allows the preparation of views through standard XHTML syntax. It allows easy creation of template layout which is common for all page views. In fact the views can be rendered with the insertion of content that is view-specific in the template.
Neutral platform- Several kinds of communications are required in ecommerce and there is a lot of data that changes hands. For the interaction of so many various kinds of systems and platform, you need a neutral standard platform that helps in this data exchange. This requirement can be filled up with XML or eXtensible Markup Language. It is quite crucial; the role of Java here is that it provides a great support to XML which combines well with this programming language.
Validation support is in-built- Server side validation support is provided by JSF. All validation can be performed by creation of validator class as well as logic that is manually coded. The server-side validation will occur automatically by virtue of JSF at the particular phase.
View rendered with several markup languages- The API technology boasts of flexible rendering that enables the attaching of several renderers to component tree of an application that is JSF-enabled. Thus custom components can be created.
Server support- Java is supported by several application servers like IBM WebSphere, BEA WebLogic, etc which are full of different types of features. Now, any one of them can be easily chosen due to the support extended.
Labour division well-defined- A huge advantage of this technology is that there is a clean separation between presentation and behaviour of web apps. This is especially great for large projects since it provides separate development areas where various team members can focus differently.
Ecommerce developers prefer Java over any other platform since it offers a number of benefits in areas such as security, ease of use, portability, flexibility and accessibility. It is present at both server as well as client sides and coupled with its efficacy this makes for an unmatched killer combination.

Ways to enhance security of Java web applications
Through web applications, end users are provided with client access for server functionality. Mostly the applications enforce intuitive, simple security policies. However, despite that recently there have been a number of attacks on them like cookie theft, cross-site scripting, browser hijacking, session riding, etc. So it is high time that we rethink the security strategy of web applications and enhance it so that it becomes harder for security breaches to take place.
Input validation- This ensures that whatever data is entered by the users or has been derived as input from applications is without any security hazards and clean. This is a very critically secure coding practice which should be implemented. The design of web applications aims to perform functions or set of functions according to user input. Generally those who attack are also users and commonly the applications used by them do not validate input since they enter arbitrary inputs to successfully perform attacks. Malicious file execution may also result due to lack of input validation. So applications should have inherent capability to validate input for protection against attacks.
Defence in depth- This defence strategy for computer systems aims towards building multiple protection layers so that possible attackers may be isolated from whatever you need to protect. To make this system more secure the approach should be combination of factors that can hinder the accessing attacker from the target; the goal should be made costly so that it proves to be unworthy for him.
Mechanism economy- This principle is a very important one and is often known as Keep It Simple, Stupid or KISS in short. This is due to the fact that architects as well as developers keep this in mind when building solutions so that they are focused on the main problem. This helps in the reduction of possibilities of attackers finding ways of accessing the application which are not foreseen or tested.
Rules validation as well as data entry- These must be performed in back end always even if the validation has already been done at front end. For web applications, input validation must be performed by using JavaScript. Validating rules both on front as well as back end allows you to have an environment which you can completely control regarding what may be or may not be allowed.
Enforcing minimum privileges- Each user and each program must be operating within the minimum privileges that are needed for their capability to perform the related duties. When this principle is followed, the damage that may arise from security breaches is limited so that the interactions between the system components may be reduced to minimum. This facilitates access control and audits case of failures or errors.
Setting standards-based fault- This helps in preparation of architecture and functionality so that decisions may be based on permission instead of exclusion. An example of this is using white lists and not black lists.
Using manifest attributes- A large number of manifest attributes helps ensure that your Java applet or application’s security is not compromised. Permissions attribute may be used for ensuring of the permission level being requested by the application to be exactly what has been specified in JNLP file or applet tag for invoking of applications. Codebase may be used to restrict JAR file’s code base to specified domains. To identify locations where the application may be found, you can use application-library-allowable-codebase. You can also identify domains from where calls may be made to the application by JavaScript code; this helps deny access of unknown JavaScript code to the application.
When considering the security aspects of Java applications one thing that should be kept in mind is that security should be implemented at every level of an application. It may not be possible for us to have applications that are 100% secure but implementing a certain amount of security measure will help eliminate some basic risks.

Why is Java considered as the most secure language?
The development language called Java is used mainly for the creation of software which may be used regularly. Most people have downloaded some program or the other that requires Java runtime. The design of the platform puts strong emphasis on the security factor. The core of the language is type-safe, providing automatic garbage collection to enhance the application code’s robustness. A verification mechanism and secure class loading ensures the execution of legitimate Java codes only. Initially the platform version resulted in the creation of safe environment to run codes that are potentially untrusted like Java applets that have been downloaded from public networks. With the widening as well as growth of the range of deployment, there has been corresponding evolvement of its security architecture so that a bigger range of services can be supported. The architecture constitutes of a large number of tools, APIs as well as algorithms, protocols and mechanisms that may be implemented.
The platform has a set of APIs that span major security areas counting public key infrastructure, cryptography, secure communication, access control as well as authentication.
Public Key Infrastructure- PKI for short, this refers to a framework which enables secure information exchange through public key cryptography. Identities are bound to digital certificates, providing a means to verify authenticity of certificates. Certificates, keys, trusted Certification Authorities which generate as well digitally sign certificates and public key encryptions are encompassed by PKI. It has two tools in-built called keytool which is used for the creation as well as management of key stores and jarsigner which is used for signing or verifying signatures of JAR files.
Cryptography- This framework helps to access as well as develop cryptographic functionality. There are some APIs which render many kinds of cryptographic services that include symmetric bulk encryption, message digest algorithm, symmetric stream encryption, digital signature algorithm, elliptic curve cryptology, password based encryption, key generators, key agreement algorithms and message authentication codes.
Secure communication- Data travelling across network is susceptible to security risks since anybody can access it; it is especially a risky business if the data is concerned with private information like credit card numbers or passwords. So the data must be made unintelligible so that unauthorized parties cannot understand it. You should also ensure that the data is being sent to the appropriate party without any intentional or unintentional modification during transport. For the best secure communication, cryptography acts as a base through SSL/TLS, SASL, Kerberos and GSS-API.
Access control- This ensures that the Java platform is protected from access to sensitive application code or sensitive resources. A security manager mediates all decisions for access control. APIs that help in this process are permissions, access control enforcement and policy.
Authentication- The process helps in the determination of a user’s identity when a Java program is being executed. Sometimes login module plug-ins while in some cases cryptography related services, are needed for authentication.
Bytecode- After successful java program compilation, a class file is generated by java compiler with .class extension containing the program’s Bytecodes. The generated Bytecodes are secure which may be run on any JVM containing machine. There is a verifier which is invoked so as to ensure the execution of just legitimate bytecodes in Java runtime. It ensures that bytecodes and Java language conform to each other so that namespace restrictions or rules are not violated. Verifier also looks for stack overflows or underflows, memory management violations as well as illegal data typecasts. After verification, the execution may be conducted.
Java is often considered as the most secure language amongst all other languages. However, still some people feel that it is not secure since the plug-ins pose some problems. In fact, they certainly do that, but the inherent nature of the language is very secure. The security infrastructure is very strong with so many APIs and tools which contribute towards making it more secure than many other languages.
