Assignment Identification, Authentication, And Authorization

Assignment Identification Authentication And Authorization Techniqu

The scenario for this assignment is based on the Acme Distribution Center, a fictitious company. You need to play the role of Sam, the system administrator. Acme is responsible for completing a huge target of 180,000 orders. It holds the reputation of having an extremely low error rate for the central distribution per the industry standards. Therefore, Acme is viewed as a model of efficiency.

Another good thing about Acme is that it operates 24X7 and even on holidays! At the Acme Distribution Center, your colleagues are the following employees: Robert, the lead warehouse receiver Jennifer, sales and accounts payable Bradley, the warehouse general manager LuEllen, the shipper Buster, the shipper Lloyd, the purchasing agent Spare, for temporary help Jennifer works in the Sales Department by day and part-time as the evening accounts payable clerk with credit memo privileges to correct customer orders. Jennifer is a valuable asset for the organization. Since she joined the accounts payable department, the late payment rate has dropped by 20% while the warehouse-shipping rate increased by 10%, and the overall profit has increased by a modest amount of 0.005% for the first reporting period.

Your General Manager, Bradley is concerned that there is a high-value inventory moving through the system, but the profits are, at best, meager for high margin items. Bradley discussed the issue of inventory volume with Lloyd to see if he knew of any reason for the miserable performance, since so many high-value items were being ordered and shipped. Your goal is to ensure that the users have only those access permissions that they need to perform their jobs effectively. A bit of research reveals that the warehouse has many goods to ship. You have developed the following matrix and scheme to identify conflicts in duties to address with the management.

This will help Acme during the pending audit and reduce asset risk. Using the following legend, provide the users with the appropriate rights and permissions: A = Assigned to the user F = Needed for primary function T = Temporary N = Never BP = By Position Assigned RO = Read Only Segregation of Duties Matrix (System User–Rights and Permissions)Department JenniferBusterBradleyLloydLuEllenRobertSpareSamReceivingAAAAAAAAShippingAAAAAAAASalesAAAAAAAAAccounts PayableAAAAAAAA Segregation of Duties Matrix (System User–Rights and Permissions)Department JenniferBusterBradleyLloydLuEllenRobertSpareSamReceiving Shipping Sales Accounts Payable After assigning the correct roles and access privileges to the users given in the scenario, answer the following questions: What were the incompatible functions in Jennifer’s access account, and why do you think such an incompatibility existed?

What were the potential conflicts and incompatible functions in Lloyd’s access account authorizations? What are the requirements for Buster and LuEllen?

Paper For Above instruction

This assignment emphasizes the importance of implementing effective identification, authentication, and authorization techniques within an organizational context, specifically focusing on the hypothetical Acme Distribution Center scenario. The goal is to analyze user rights and permissions based on a detailed access rights matrix, identifying potential conflicts and segregation of duties issues to mitigate risks and ensure operational integrity.

Introduction

In the modern organizational environment, maintaining secure and efficient access control is critical for safeguarding assets, preventing fraud, and ensuring operational efficiency. Properly implemented identification, authentication, and authorization techniques form the core of a secure access management framework. In this paper, we explore these concepts through the lens of the Acme Distribution Center scenario, illustrating how role-based access control (RBAC) frameworks can be used to assign appropriate permissions, manage conflicts, and enforce segregation of duties (SoD).

Identification, Authentication, and Authorization Framework

Identification involves establishing the identity of a user through credentials such as usernames or IDs. Authentication verifies that the presented credentials are valid, typically via passwords, biometrics, or two-factor authentication. Authorization determines what actions a verified user can perform within the system based on their roles and permissions. Together, these processes form a multi-layered security approach that prevents unauthorized access and limits user capabilities to their job requirements (Ferraiolo & Kuhn, 1992).

Role-Based Access Control in the Acme Scenario

At Acme, access permissions are assigned according to employee roles and responsibilities, reflected in the provided access rights matrix. This matrix segments duties among various departments, including receiving, shipping, sales, accounts payable, and management. Such role-based access control ensures users can only perform functions relevant to their duties, reducing the risk of internal fraud and operational errors (Sandhu et al., 1996).

Analysis of Jennifer’s Access Rights and Potential Conflicts

Jennifer holds roles that combine sales and accounts payable functions. The access matrix indicates she has permissions across multiple departments, which could include tasks that are incompatible or segregated to prevent conflicts. For example, if Jennifer has both sales and accounting rights, she might be able to process sales transactions and also modify payment records, leading to potential fraud or errors. The incompatibility likely existed due to overlapping responsibilities or insufficient role segregation during system setup, which can undermine internal controls (Moore et al., 2018).

Analysis of Lloyd’s Access Rights and Potential Conflicts

Lloyd, as the purchasing agent, requires permissions that enable him to manage procurement activities. However, if Lloyd’s access overlaps with inventory control or shipping functions, conflicts could arise, such as unauthorized inventory adjustments or shipment approvals. Potential conflicts include Lloyd executing orders that bypass approval processes or manipulating purchase data for personal gain (Viega et al., 2003). Proper segregation of duties, such as separating purchasing from inventory management, is essential to prevent fraud and errors.

Requirements for Buster and LuEllen

Buster, as a shipper, needs access permissions related to outbound logistics, such as viewing and processing shipping orders. LuEllen, as the general shipper, should have permissions that facilitate the actual shipment process, including order validation and dispatch. Their permissions must be carefully calibrated to allow efficient workflow while preventing unauthorized modifications to shipment details or access to inventory management functions.

Segregation of Duties (SoD) Principles and Practical Implementation

The core of effective access control lies in enforcing SoD principles by ensuring no single user has conflicting privileges. This minimizes risk by dividing responsibilities among different personnel. For example, the same individual should not have both the authority to create purchase orders and to approve or receive inventory. Role-based access matrices must be regularly reviewed and updated to adapt to organizational changes and emerging threats (Balanson et al., 2009).

Conclusion

Effective implementation of identification, authentication, and authorization techniques, especially role-based access control, is vital for maintaining operational security and integrity. The Acme scenario illustrates common challenges related to conflicting roles and inadequate segregation of duties. Addressing these issues through systematic role analysis and permission management can significantly reduce risk, support compliance, and enhance organizational efficiency.
