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 …show more content…
Constrained User Interface incorporates similar concepts of two other access control models that have been detailed, Role Base and Rule Base. Constrained User Interface is defined as a user’s ability to get into certain resources based on the user’s rights and privileges. These rights and privileges are restricted and constrained on the asset they are attempting to access. While this requires many levels of protection it provides limitations on the request access to the resources available within the organization. Another example of a access control model that can be applied in this situation is known as the Clark and Wilson Integrity Model. This model provides improvements from the Biba Integrity Model of access control. Developed by David Clark and David Wilson, the mode concentrates on what happens when a user tries to do things they are not permitted to do, which was one flaw of the Biba Integrity Model . The other flaw that was addressed was the model also reviews internal integrity threats . There are 3 key elements of the Clark and Wilson integrity model; the first it stops unauthorized users from making changes within the system. The second, it stops authorized users from making improper changes, and the third, it maintains consistency both internally and externally . Within the Clark and Wilson model a user’s access is controlled by

The following groups (ShopFloor), (HumanResources), (ShopFloor, Manger), and (HumanResources, Manger) will be created with designated acces contols. (ShopFloor, Manger) and (HumanResources, Manger) groups has a common inherited object which is Manger. Access control will be granted based on the two groups needing to access the same object.
Control can be denied by limiting and clearly marking the approaches to buildings and properties, thereby channeling visitors into a defined area. Natural Access Control is the use of building and
Natural access controls are ways of making access limited to one or two areas, this is done by
The CRUD Security Matrix: A Technique for Documenting Access Rights by Lunsford & Collins (2008) mentioned to three types of access controls with more details: Mandatory access control (MAC), which must mean users get access formal clearance in all parts of the object before acquiring access to an object. In fact the administrator to delete a user based on the sensitivity of the information is responsible in the object and the level of the user's permission. The user is not entitled to other users to access the object. But in discretionary access control (DAC) grant or deny users access to objects under their control. It said DAC is the weakest form of access control; but it is useful in many places, and control role-based access (RBAC), the
The policies and procedures will be implemented using access control models. These models will work to enforce the rules and objectives of our security policy and will also dictate user access. Using a discretionary access control (DAC) model will allow the owner of the resources to control who has access as well as the operations that can be performed. Access will be based on the identity of the user and the role that the user plays within the company. This can be done through access control lists (ACLs), where permission is granted on a need-to-know basis.
Attribute Based Access Control (ABAC) models make utilization of characteristics claimed by the customers, the suppliers, and some different credits identified with the network. Decisions about access or deny are simply based on these attributes (Yuan & Tong 2005).
This is as opposed to ordinary techniques for access control, which allow or disavow client access on an inflexible, object-by-item premise. In RBAC, parts can be effectively made, changed, or stopped as the needs of the undertaking develop, without needing to exclusively redesign the benefits for each client.
The remote access policy is applicable to the employees, contractors, vendors and agents of an organization and also companies PCs or work stations which can be connected with bank network. This mainly allows the remote access connections of Five-fourth bank corporate network, which is useful in sending emails, viewing the web resources and so on. It includes all the technical implementations of a remote access to link the bank network
There is a wide range of computing environments and products that support these environments, with each one having distinctive security needs. Computing systems must have the flexibility to support many diverse types of security operating systems. This is the crux of the problem that has facilitated research into finding a system that is multi-faceted and able to provide fine-grained controls identifying who has access to which levels of data, determine which users have permission to information based on policies and procedures, and revoke access rights that had been established previously.
