The present generation of youth begins the day with the Facebook or other social website. Hundreds of millions of people all over the world make use of social websites, Internet portals, blogs, Wikis, etc. These sites such as MySpace, Facebook and YouTube have the essential features and equipped with the necessary computing facilities to keep gigantic online communities get going with secure manner. Due to rapid growth of networking, use of social networking sites in day to day life, data sharing, computer security has made a vital part of computer research & development. For maintaining the security in various applications like Ecommerce Online goods and services, Banking, Marketplace services Advertising, Auctions, Comparison shopping, Mobile commerce Payment, Ticketing, An electronic payment system (EPS),Online insurance policy management, we have to use high secured operating systems. In this regard a number of extremely secure operating systems i.e. Trusted Operating Systems like SELinux, Argus, Trusted Solaris, Virtual Vault have been developed by companies such as Argus-Systems Group, Hewlett-Packard, and Sun Microsystems to handle the increasing need of security. Normally, due to high security reason these operating systems are being used in defense. But still these secure operating systems have limited scope in commercial sector and are not popular in corporate due to lower performance; actually this security will come at a cost. In this paper we will propose SPF Model to maintain the balance between security and performance for these operating systems. This SPF model of TOS can be implement for various applications. For implementation of these SPF based trusted operating system we propose object oriented based Code generation i.e. forward engineering i.e. process of generating source code from one or more OO Rational Rose model for web application like social networking. In this research paper we will discuss the issues and UML-based software development solutions for SPF to manage the security, performance and modeling for Social networking sites.As the architecture in Figure 1.b shows, the additional security checks in the kernel will cause Trusted Operating Systems to be slower than traditional operating systems [5]. If we implement the same trusted operating system for web applications like social networking sites, e-commerce sites, job portals, then we get lower performance but more security User Applications Middleware Read(),Write(), Send(),Receive(), Share (), Post (), etc. Kernel Security Checks in ordinary Operating Systems Rest of the Kernel Hardware Part (a) User Applications Middleware Read(),Write(), Send(),Receive(), Share (), Post (), etc.
In this paper we will propose model driven software development and Security Performance Framework (SPF) Model to maintain the balance between security and performance for web applications. We propose that all security in a Trusted Operating System is not necessary. Some non-essential security checks can be skipped to increase system performance. These non essential security checks can be identified in any web application. For implementation of this Security Performance framework based trusted operating system, we propose object oriented based Code generation through forward engineering. This involves generating source code of web application from one or more Object oriented Rational Rose model. The novel integration of security engineering with model-driven software expansion approach has varied advantages. To maintain security in various applications like Ecommerce, Banking, Marketplace services, Advertising, Auctions, Comparison shopping, Mobile commerce Payment, Ticketing, Online insurance policy management, we have to use high secured operating systems. In this regard a number of trusted operating systems like Argus, Trusted Solaris, and Virtual Vault have been developed by various companies to handle the increasing need of security. Due to high security reason these operating systems are being used in defense. But still these secure operating systems have limited scope in commercial sector due to lower performance; actually this security will come at a cost. This paper analyzes UML-based software development solutions for SPF to manage the security, performance and modeling for web applications.
This paper describes UML-based foundations for model driven architecture and forward engineering of UML static models. In this paper, we propose an integrated environment for designing object-oriented enterprise models. In this projected process for Fast Prototyping, we design object models like use case diagram, sequence diagram, class diagram, etc. We use object-oriented conceptual modeling techniques to design and develop various applications like E-commerce, Banking, Comparison shopping, Ticketing, Online insurance policy management, product purchase system, etc. This paper suggests forward engineering to generate source code from object models through IBM Rational Rose software. This object oriented source code help software development team from analysis to maintenance phase as well as for round trip engineering. Due to high security concern, we have to use highly secure operating systems as a platform to run these web applications. In this regard, a number of trusted operating systems like Argus, Trusted Solaris, and Virtual Vault have been developed by various companies to handle the increasing need of security. The novel integration of security engineering with modeldriven software expansion approach has various advantages.As we observe that all security checks in a Trusted Operating System is not necessary. Some non-essential security checks can be skipped by administrator to increase system performance. These non essential security checks can be easily identified at the time of requirement analysis. For example, the majority of web servers deal with pure public information. The majority of data on a web server is publicly readable and available to all users, but these users should not be capable to change the data on the web server. In this application, the need for security checks during reads from disk seems like a waste of CPU cycles. The real security need for web servers seems to be the security of write accesses, not read accesses. In this paper, we propose code generation, Class identification and Modeling for web applications through UML 2.0. Further we propose Security Performance flexibility model for the same to maintain the balance between security and performance for web applications.
