A multi-million dollar project with over 120 person years of effort, Chameleon's success could only be achieved through a spirit of co-operation and outstanding team work between ourselves and IBS. They created product to our specifications and worked with us in implementing system for two business units resulting in very smooth transitions for them. As project owner I could not have asked for more," added Akshay Shrivastava - Manager-Information Services, Cargo and Logistics, Emirates Group IT.

Special features enable data communication using mobile computers and handheld devices to improve flow control and piece-level tracking, and hence reduce operational errors. The system is expected to improve productivity and service levels by automating workflow, enabling paperless internal processes, and monitoring processes and performance. It also provides customers, suppliers and other partners direct control over logistics, processes and costs, while offering an advanced tool that boosts productivity and profitability - all of which will help Emirates to quickly boost its cargo revenue.

To restrict access to users for certain resources of an application, a process of identifying users becomes a necessity. Authentication enables to restrict a user to access resources by certain ways. It could be a combination of a username and password, a digital certificate, a smart card or a fingerprint reader. The validity of information provided by user helps identify user, so that user is provided access to requested resources. The process of successful identification of user implies that user is authenticated.

After identification of user is over, next step is to determine whether authenticated user has access to resources. The process of determining access to resources for a particular user is known as Authorization. In Windows based systems, resources have an Access Control List, which provides a list of users who have access to that resource. The list also specifies kind of access such as read, write, modify, and delete resource, for each user. For example, if a user requests an ASP page, operating system checks whether user has Read access to page and if user has read permission, then operating system allows IIS to fetch page. The IIS has authorization settings which enable IIS to control access of resources by users. File Access Control Lists are set for a given file or directory using Security tab in Explorer property page.
