Humans have always felt the need of possessiveness of their belongings. Since ancient times, inhabitants used to live in secure caves so that they would be protected from unwanted attack from deadly animals. The improvement of civilization witnessed better and improved means of home system security being implemented by humans. Technological revolution of modern age has resulted in concept of home security finding widespread popularity. Everyone worth his salt thinks of protecting his hard earned precious possessions. Urban population particularly has become very careful of the important aspect of home security. India security system has several useful tools available to protect their beloved home. One can find latest technological innovations being employed to protect not only houses but also offices, buildings, and warehouses etc. Nobody likes to be robbed of his precious possessions and hence opting for a systems security makes sense. Also the fact that, crime rate has kept increasing further emphasizes the need of upgrading the home security. With changing times, even petty thieves have acquired new skills to rob your belongings. Most of the urban cities and metros are witnessing increased rate of crimes and that requires for installation of a safe and secure system to protect your valuables, family and home. To best explain the notion of a secure service, we will use the example of a healthcare application. Suppose we wish to get our credit report. We will contact a service provider that gets credit reports. First we should have the access to read the existence of such a service provider. Once we know about this service provider, we invoke this service provider. The service provider should ensure that we have the access to this particular service. Furthermore, it should ensure that the information about the credit it retrieves can be read by us. In order to do this, we also have to send some identification information to the service provider. If the service is not secure then anyone can obtain anyone's credit reports. Similarly, to obtain healthcare reports, the secure service provider should ensure that the person requesting the service has the appropriate credentials to read the healthcare records. Furthermore, the owner of the healthcare records may enforce various privacy policies in which case the service provider should only release appropriate information to the consumer. In some cases the consumer may use the service provider to purchase information. The service provider can state its privacy policies and if the consumer agrees with the policies, it can release private information about him/her. This simple example shows several aspects. One is that the user of the service has to be attested by the service provider. The service provider has to be trusted in the sense one does not want to get service from an unreliable provider. The service provider has to ensure that the user/consumer has the proper credentials to obtain the service and that any information released is something the consumer is authorized to read. The service provider also has to ensure that private information about a person is not released to the consumer. Essentially we need confidentiality, privacy, trust and integrity features to be enforced by the web services. |
