Offshore application security model for a leading public utility company
 
 
The client
The client is responsible for the operation of gas transmission and distribution throughout United Kingdom. It provides a state of the art information system to customers, employees and shippers. It operates more than 276,500km of pipeline in the UK. Its network of transportation system supplies gas to nearly 20 million customers through 60 shippers.
 
The challenge
The client wanted the target system to integrate real-time feeds from telemetry data and supply forecasting across the country and MIS applications. The challenges were made even greater by the business criticality of the application, and its distributed 3-tier architecture, which made security a very critical feature of the system itself.
 
The solution

Wipro conducted business workshops to understand the monitoring process of the application and suggested suitable deployment and technical solution. This was followed by architecture, design and implementation of the security solution using Netegrity SiteMinder, an access management security product, used to securely manage user access across applications. However, since SiteMinder deployment alone could not have achieved all the application security requirements of the system, additionally, a security administration module was also integrated with the application to provide role administration and reporting facilities.

The security features implemented for this project comprise of,
Authentication (UserId/ Password, SSL Certificate) and Single Sign On for all the web applications
Authorization Model that can be deployed in any application where SiteMinder or a similar Access Management product is chosen to implement Access Control.
Role Based Access Control - the security process intercepts all the user requests and performs an Access Control Check/User Validation before authorizing a user to gain access
Personalization Framework that can fit into all systems with similar requirements based on user privileges
Data Security - achieved by restricting user access to business activities of only those control centers to which he/she is associated.
Encryption - to ensure non-repudiation of business transactions
Audit and Reporting – Log and monitor business related events
 
Business benefits delivered
Wipro helped the client realize the project goals and achieve:
Flexible security model can be deployed in any application with an access management product
Reduction in deployment costs to the client due to Wipro’s Offshore Development model
Easy integration with other applications and infrastructure components
Substantial reduction in administration costs and complexity through Single Sign On
Integrated one-view of employees, shippers and clients simplifies processes and minimizes costs
Significant reduction in management and operational risks using Rational Unified Processing (RUP) model
Extended Unified Security model for customer’s existing and future applications, achieving reduction in operation costs
