Network Security for E-commerce

  •  A network security is defined as a circumstance, condition with the potential to cause economic hardship to data or network resources in the form of destruction, disclosure, modification of data, denial of service, and/or fraud, waste, and abuse. 
  • The discussion of security concerns in electronic commerce can be divided into two broad types: 1. Client-Server Security 2. Data and Transaction Security

1. Client-Server Security 
  •  Client/server security uses various authorization methods to make sure that only valid users and programs have access to information resources such as databases. 
  • Access control mechanisms must be set up to ensure that properly authenticated users are allowed access only to those resources that they are entitled to use.
  •  Such mechanisms include password protection, encrypted smart cards, biometrics, and firewalls.

2. Data and Transaction Security
  • Data and transaction security ensure the privacy and confidentiality in electronic messages and data packets, including the authentication of remote users in network transactions for activities such as online payments. 
  • The goal is to defeat any attempt to assume another identity while involved with electronic mail or other forms of data communication. 
  • Preventive measures include data encryption using various cryptographic methods.

Explain CORBA architecture briefly.

  ARCHITECTURE OF CORBA The major components that make up the CORBA architecture include the: Interface Definition Language (IDL), Object Request Broker (ORB), The Portable Object Adaptor (POA), Naming Service, and Inter-ORB Protocol (IIOP). Interface Definition languages: CORBA uses the concept of an interface Definition language to implement the services. IDL is a neutral programming language method of defining how a service is implemented. The syntax of this language is independent of any programming language. IDL is used to define an interface, which describes the methods that are available and the parameters that are required when a call is made for a remote object. Object Request Broker (ORB): The foundation of CORBA architecture is based on the Object Request Broker (ORB). The ORB is prime mechanism that acts as a middleware between the client and the server. It provides a heterogeneous environment in which a client can remotely communicate with the server irrespective of t...

   Functions/Process of Management The management system is a system or process of interrelated and sequential components or function of management. The function of management have been specified and defined variously by different authors. Fayol has specified planning, organizing, commanding, coordinating and controlling as the function of management. Likewise, according to Koontz and O'donnell, planning, organizing, developing, coordinating and staffing as the functions of management. According to Linder Urbick, forecasting, planning, organizing, commanding, coordinating and controlling as the function of management. Luther Gulick has summarized the function of management as POSDCORB where P = Planning, O = Organizing, S = CO = Coordinating, R = Reporting and B = Staffing, D = Directing, Budgeting. In general, the following are the functions of management. 1. Planning Planning is the basic function of management. It is outlining the future course of action and decides in adva...

Short note on E-Government Architecture

-
Image
1)  Presentation layer The presentation layer identifies and describes the system users, who require access to government information at different capacities, and the channels through which information can be accessed.  During system development, one is required to explicitly identify the government user, the system is intended to serve, and also the means through which this information is to be accessed so that the system can be tailored to meet these requirements. It manages the user’s interface with the system. If a pro- project is to be successful, different stakeholders need to be identified at the beginning, involved in the initial stages and kept involved throughout development and implementation. 2) E-government layer E-government public services utilize very specialized applications that are only available to certain agencies and not all agencies participating in the consortium. The main goal of the e-government layer is to achieve a government that;  does not as...
