Richman Investments has decided to expand their business. We have been given their new growth projections of 10,000 employees in 20 countries, with 5,000 located within the U.S. Richman has also established eight branch offices located throughout the U.S. and has designated Phoenix, AZ being the main headquarters. With this scenario, I intend to design a remote access control policy for all systems, applications and data access within Richman Investments. With so many different modes of Access Control to choose from it is my assessment that by choosing only one model would not be appropriate for Richman Investments. My recommendation would be a combination of multiple Access Control Models that overlap to provide maximum coverage and overall security. Here are my suggestions for access controls. Role Based Access Control or RBAC, this will work well with the Non-Discretionary Access Control model, which will be detailed in the next paragraph. RBAC is defined as setting permissions or granting access to a group of people with the same job roles or responsibilities . With many different locations along with many different users it is important to identify the different users and different workstations within this network. Every effort should be dedicated towards preventing user to access information they should not have access to.
Non-Discretionary Access Control is defined as controls that are monitored by a security administrator. While RBAC identifies those with permissions, it is a security administrator that should further identify the level of access to each Role that is created. The security administrator should also designate certain users or workstations access to the information available within the network. Rule Based Access Control can also be linked to the first two models detailed in the paper (RBAC and Non-Discretionary), and is similar to RBAC. Rule Based Access Control is a set of rules to determine which users have access to
