Security Loopholes
Utpal had just joined SystemX as Systems Manager. But he was a worried man looking at the current state of affairs at SystemX. As a part of assessing hardware and software requirements, it was found that out of the 364 desktops at the corporate office; more than half did not have their antivirus software updated with recent virus signature files. Three fourths had not changed the default e-mail password (it was the user name) and no one had installed OS patches. And one of its local mail servers seemed to be an open relay! For a fleeting moment, he wondered about the situation at the seven branch offices across the country.
SystemX used the Net extensively in dealing with its branches, customers and suppliers. Information like contract documents, marketing plans, Cheque and Draft numbers, bank account details and collection details were regularly transmitted by e-mail. Utpal's first thought was that he would recommend that SystemX bring in a security consultant. But the budget constraints meant that his recommendation was unlikely to find favour. He was beginning to feel a bit out of depth and was wondering what he should do to ensure that SystemX's data remained safe and secure.
Questions:
1. What security loopholes come to the fore in the situation described? How can these be plugged?
2. What is the importance of a "security budget" in the context of the given situation?

Q.5
Discuss the case study with answers of following questions.
Order Fulfillment Process
Order fulfillment is a common process found in practically every company in the USA. The process begins when a customer places an order, ends when the goods are delivered, and includes everything in between.
Typically, the order fulfillment process involves a dozen steps performed by different people in different departments. First, someone in
14

customer service receives the order, logs it in, and checks it for completeness and accuracy. Then the order goes to finance, where someone else runs a credit check on customer. Next, someone in sales operation determines the price to charge. Then, the order travel to inventory control, where someone checks to see if the goods are on hand. If not, the order gets routed to production planning, which issues a back order.
Eventually, a warehouse operation develops a shipment schedule. Traffic determines the shipping methods such as rail, truck, air, or water, and picks the route and carrier. Product handling picked the products from the warehouse, verifies the accuracy of the order, assembles the pickings, and loads them. Finally, traffic releases the goods to the carrier, which takes responsibility for delivering them to the customer.
Common complaints that most companies received are: first, once an order enters the process, no one can tell the customer where the order is when it will arrive. Second, errors are investable with so many people having to handle and act separately on the same order. Thirdly, even if every person involved in it did his or her job perfectly and in exactly the time allotted, the process would still be slow error-prone. Finally, the process can't be made flexible enough to deal with special requests or to respond to inquiries.
Questions:
1. What are the root causes of the problems?
2. If you are a manger, how you can resolve all such problems? Discuss in detail.
