Case Study:Threat Tree
Suppose there is a Social Department of Municipality of New Delhi divided into three subgroups: the Financial Section, the Children’s and Family Section and the Custody and Non-Institutional Care Section. There are about 40 employees in the organization. The major activity of social department is to investigate reports and applications directed to (IFO) Individual and Family Care to determine what contributions are needed to be made for the client. like institutional care or a contact person. There is no information security policy documented. The employees are allowed to bring laptops and their unfinished work home. As the department is handling sensitive information about e.g. addicts, incest case and recipients of social assistance, the problem of the confidentiality is significant. The personnel have no education in information security. Decisions are made when a situation arises, but they are only verbal agreements. This can endanger both the integrity and confidentiality of the client. The information is a huge security concern.
