ITS3104 IT Security - Course Project © 2016 South University Scenario A tire manufacturing company, who wishes to be called ABC, Inc. to protect its privacy, has recently fallen victim to a cybercrime. The customer information and some of its proprietary technology were compromised in the attack. This company has been in the business for a very long time and enjoys a large market share. If its identity is disclosed, the attack has the potential to cause it to lose customer confidence. Also, some of its competitors are constantly looking for opportunities to hack the company's important strategic and functional information. The company's head, Dermot Reed, is very concerned about the situation because a recent study shows that some of its competitors have started using its techniques. The source of the attack remains unknown. It could be that an internal, disgruntled, or greedy employee has been involved in the attack or has been revealing important information to its competitors. Moreover, there have been several attempts at hacking the company in the past, which have been unsuccessful prior to this incident. Ed Young, the network administrator, has requested a budget for a system overhaul to rebuild the infrastructure of the organization with an emphasis on security. The company does not have anything currently in terms of true security measures. Young is competent but has limited understanding of attack methodologies. The attacks were thwarted mainly due to automated antivirus programs installed on the servers. ABC, Inc. has a network with four servers that cater to around 450 employees. ABC, Inc. keeps track of its data using a MySQL database. However, some of the data is incorrect in its database since somebody has modified it outside of normal business operation hours. The database server is used for updating the inventory records. The database contains information about quantity of raw materials available, quantity of finished products, price of finished products, etc. Users from across the organization use the database to access different information. Therefore, availability of the server is critical. Young would like a recommendation from you on the fault-tolerance mechanism that can ensure uninterrupted business and security on the database to prevent unauthorized modifications. Ken Burton, the sales and marketing head is worried about the security of the laptops that the sales and marketing personnel carry with them while traveling. Burton has previously reported that data on these laptops has been leaked or hacked when these laptops are outside the organization’s network. Burton wants a system by which these computers can be secured while they move out of the organizational network and still maintain a secure connection to the home network. 2 In addition to the concerns above, ABC, Inc. wants to implement a computer use policy for its users that explains their responsibilities and the internal and legal implications to users who violate this policy. The intent is to prevent users from indulging in activities that put the company at risk. ABC, Inc. needs to create a charter that describes the following:    Hacking Violation of right of ownership Violation of privacy of user's personal data The management of ABC, Inc. decided that adequate security measures are required to protect internal data and entrusted Young with the responsibility of creating the security requirements. Young has created the following additional requirements:          User authentication must be performed before an employee can logon to the network. The organizational structure is given in Appendix A. Each department stores its data in separate folders that are shared in a central file server. Measures need to be taken to enable only the users in a department to access the department folder in the central file server. Personnel in a particular department should not be able to access the folder of another department. In addition, a mechanism is required that would record event data on each department folder on the central server. The network administrator will use this data to identify the events that generated security alerts. The computers in the accounts department need to be made secure. Employees in other departments currently use these computers as well. Sensitive data on these computers are accessible to any user who has physical access to the computer. A mechanism needs to be devised by which data belonging to a user on the local machine is accessible to that user only. Young suggests using encryption to secure data on local computers. The OSs installed on the computers need to be updated with the latest patches and fixes. All users in the organization currently use the database. However, only the heads of the departments, the network administrator, and the database administrator should have access to the database. The database administrator should have full control permissions, the department heads should have modify rights, and the network administrator should have read-only permission on the database. The computers in the marketing department need to be secured when the computers move out of the network. All computers in the organization are run on an outdated OS. The organization has identified that some of the hacking has occurred because computers running on this OS can be accessed from outside the organizational network by using terminal services. The OS needs to be updated and configured to prevent outsiders from accessing the computers. A mechanism is required to check if the computers in the organization are running the latest patches. In addition, a mechanism is required for implementing antivirus in the computers in the organization.
