Research Paper: Outline Security Policy.

Scenario: To stay competitive in the financial institution market, the First World Bank Savings and Loan wishes to provide all banking services online to its customers. These services also include the online use of credit cards for loan applications. The organization estimates over $100,000,000 a year in online credit card transactions for loan applications and other banking services. A task team has been formed to study the cost, performance, and security of maintaining a Linux and open source infrastructure. According to rough estimates, annual cost savings in licensing fees alone can be up to $4,000,000. At the same time, the confidentiality, integrity, and availability (CIA) triad perspective needs to be taken into account for infrastructure maintenance.The task team has engaged a network engineer with the network and routing design. The team has determined the following server services that would be needed to support the online transaction infrastructure:

?? A database server

?? A Web server

?? A file server

?? A Simple Mail Transfer Protocol (SMTP) server

?? A Lightweight Directory Access Protocol (LDAP) server

All servers would be physically located in a third-party data center.
