Once Again Let Us Considerabc Inc Answer The Following Questionfo

Once again, let us consider ABC, Inc. Answer the following question. For access control, MAC, DAC, and RBAC are the popular options. In the context of ABC, Inc., state which of these are appropriate, with a brief justification. ABC Inc. is trying to purchase advanced authentication servers to accommodate the increasing customer activity. The CFO (chief financial officer) prefers to go with the lowest bidder. However, the CSO (chief security officer) prefers a more systematic approach. On behalf of the CSO, write a brief note to the CFO stating the aspects that need to be taken into account in the choice. ABC Inc. has a COO and a CSO. While the COO (chief operations officer) is responsible for the overall operation of ABC Inc., the CSO (chief security officer) is responsible for the security. Both report to CEO who, in turn, reports to the Board of Directors and to the Shareholders. Is there a need for intrusion detection in ABC Inc.? Which type(s) of products do you recommend? Justify. Do you think the defense-in-depth is relevant for ABC, Inc.? Justify.

In contemporary corporate environments, implementing effective access control mechanisms is crucial for safeguarding sensitive information and ensuring authorized access. Three prominent models—Mandatory Access Control (MAC), Discretionary Access Control (DAC), and Role-Based Access Control (RBAC)—offer distinct approaches suitable for various organizational needs. For ABC, Inc., a company experiencing increased customer activity, RBAC is particularly appropriate. RBAC assigns permissions based on roles within the organization, simplifying management and aligning security measures with organizational responsibility structures. This model enhances security by ensuring that users only access information pertinent to their roles, reducing the risk of privilege escalation or accidental data breaches (Ferraiolo, Kuhn, & Chandramouli, 2003).

When considering the procurement of advanced authentication servers, ABC's leadership must adopt a systematic approach rather than solely seeking the lowest bidder. Key aspects include evaluating the security features of the authentication solutions, scalability to support rising customer activity, vendor reputation, compliance with industry standards, and integration capabilities with existing systems. Furthermore, total cost of ownership, including ongoing support and maintenance, and the potential for future upgrades should inform the decision. A systematic evaluation ensures the selected solution provides robust security, reliability, and long-term value, aligning with organizational security policies and risk management strategies (Oza, 2014).

Within ABC, the roles of the COO and CSO highlight the importance of coordinated security and operational strategies. While operational efficiency falls under the COO's responsibility, the CSO must focus on safeguarding infrastructure and information assets. When communicating with the CFO about security investments, the CSO should emphasize risk mitigation, compliance requirements, and the potential consequences of security breaches. Aspects such as alignment with best practices, integration with existing security frameworks, and vendor support are critical. The note should clarify that investing in comprehensive security measures, including advanced authentication, is a strategic decision to protect organizational assets and reputation, which justifies a systematic approach beyond cost considerations.

Given the increasing sophistication of cyber threats, intrusion detection systems (IDS) are highly recommended for ABC, Inc. An IDS monitors network traffic and system activities to identify potentially malicious behavior, providing early warning of security breaches. Types of IDS include network-based intrusion detection systems (NIDS) and host-based intrusion detection systems (HIDS). For a growing company like ABC, NIDS can monitor global network activity, while HIDS can protect critical assets at the host level. Combining both offers a layered defense, enhancing detection capabilities and enabling rapid response to threats (Scarfone & Mell, 2007).

Defense-in-depth is highly relevant for ABC, Inc., especially considering its increasing customer activity and the critical need to protect sensitive data. This security strategy involves deploying multiple layers of defense—such as firewalls, intrusion detection/prevention systems, access controls, encryption, and security policies—to create a comprehensive security posture. This approach reduces the likelihood of a successful attack, as breaching one layer does not compromise the entire system. In fast-evolving threat landscapes, defense-in-depth ensures resilience, compliance, and continuous protection of organizational assets (Anderson, 2020).
