A Data Centre was full of hundreds of Departmental Web Application Servers (WAS) combined with respective Database Servers (DBs) to deliver Government services. The WASs were maintained in Demilitarized zone of the DC while the DBs were separately maintained in a different Firewall Zone. In one fine morning it was suddenly discovered that the one particular web based Application (A) was displaying an odd image in the middle of the screen and nothing could be done with it. It was realized that the server was hacked. Given the situation you are requested to analyze and find out the possible means and ways by which this 'A' was hacked.
In the DC environment as stated in Case Study I one Departmental Web Server was found to have been responding to requests very slowly and gradually reached a state of unavailability. However, the server cannot be said 'down'. As per health status, it was UP and running. You are requested to analyze and find out the possible reasons for such unavailability.
An application was planned and designed to serve a specific exam result of 10 lac candidates. The candidate was to enter roll no and the application was supposed to display the total marks secured by him/her. The consultant of the respective department demanded for 4 high-end servers with dedicated storage for the purpose and delivered the results successfully. You are requested to determine the possible reasons of asking four (4) high-end servers in place of one (1). What was the actual configuration to deliver the services successfully?
The application developers of a department once installed a LAMP based application which was supposed to deliver some Government services to the people. While resolving an issue it was discovered that the database server was accessed by, (perhaps) an intruder at a time when the application was not actually serving. Please find out what could be possible actions / attacks which could have been performed by the intruder and what could have been the losses in terms of CIA?
A few application developers of a Department were deploying a Software Application for delivering their services. They hired some space from the on-premise Cloud of the above-stated DC as IaaS. They downloaded the Operating System and all other System Software using the DC net service and installed these along with the Application within the stated space (Infrastructure). But it was observed that their application was failing at various stages and in various occasions. Assess the possible reasons for such failure.
