Risk Assessment For A Large Fictitious Organization: Access

Risk Assessment for a Large Fictitious Organization: Access and

This paper explores the comprehensive risk assessment process for a large, fictitious organization, focusing on issues related to identity and access management. The organization, named GlobalTech Solutions, is headquartered in the United States and operates in multiple countries across North America, Europe, and Asia. As a rapidly growing enterprise specializing in software development and cloud services, GlobalTech Solutions has an intricate organizational structure comprising multiple departments, including research and development, sales, customer support, and IT infrastructure management. The structure is hierarchical but also emphasizes cross-departmental collaboration, with a defined chain of command and communication channels to ensure operational efficiency.

GlobalTech Solutions’ primary operations involve deploying cloud-based software solutions, managing customer data, and supporting international digital platforms. The organization must adhere to jurisdiction-specific data sovereignty laws, such as the General Data Protection Regulation (GDPR) in Europe and the California Consumer Privacy Act (CCPA) in the United States. The company’s success hinges on maintaining secure, efficient, and compliant access to sensitive data and IT resources, which necessitates robust identity and access management (IAM) practices.

Scenario and Use Cases for Risk Assessment

The risk assessment focuses on potential threats stemming from inadequate access controls and permissions management. The following scenario exemplifies a critical threat:

Scenario: An insider threat arises when a disgruntled employee with excessive access rights, gained through improper provisioning or role changes, attempts to exfiltrate sensitive customer data. This threat underscores the importance of precise access controls and continuous monitoring.

Use Case 1: Employee Provisioning

In the current process, new employees are onboarded with access rights assigned via Active Directory groups. However, when employees change roles or leave the organization, their access isn’t consistently revoked or adjusted, leading to privilege creep and unauthorized access. This insecure practice increases the risk of data breaches and insider threats.

Use Case 2: Separation of Duties

Admin accounts permit extensive privileges, including server management and Active Directory modifications. Currently, administrators can create accounts, delete groups, and alter logs without sufficient oversight, violating the principle of least privilege. This poses risks such as insider abuse, accidental misconfigurations, or data tampering. Segregation of duties is crucial to prevent privilege abuse and ensure regulatory compliance, such as with Sarbanes-Oxley (SOX).

Additional Use Cases

1. Third-Party Vendor Access Management: External contractors require temporary access to the organization’s systems. The current lack of automated de-provisioning exposes the organization to risks of lingering access after contracts end, increasing breach potential.

2. Multi-Factor Authentication Enforcement: Employees accessing sensitive data use single-factor login processes, rendering accounts vulnerable to credential theft. Implementing multi-factor authentication (MFA) reduces the risk of unauthorized access, especially on remote or untrusted devices.

Risk Assessment Planning and Methodology

The risk assessment will adopt a systematic, multi-phase approach aligned with industry standards such as NIST SP 800-30 and ISO/IEC 27005. The process includes:

• Asset inventory and classification: Identifying critical systems, data repositories, and access points vital to organizational operations.
• Threat identification: Cataloging potential malicious and negligent threats, including insider threats, phishing attacks, and system misconfigurations.
• Vulnerability analysis: Evaluating current access controls, provisioning processes, and audit measures to identify weaknesses.
• Likelihood estimation: Assessing the probability of occurrence based on current controls, historical incident data, and threat intelligence.
• Impact analysis: Determining potential damages to business continuity, compliance status, and reputation in the event of a breach.
• Risk determination: Combining likelihood and impact to prioritize vulnerabilities for remediation efforts.

Collaborative Teams Involved

Effective risk assessment necessitates collaboration among various organizational units:

• Information Security Team: Leads the risk assessment, defines evaluation criteria, and implements controls.
• Human Resources: Facilitates employee onboarding, role management, and offboarding procedures.
• IT Operations and Infrastructure: Provides technical insights into system configurations, access logs, and monitoring tools.
• Legal and Compliance: Ensures regulatory requirements such as GDPR, CCPA, and SOX are integrated into risk mitigation strategies.
• Executive Management: Approves policies, allocates resources, and oversees strategic alignment.

Impact of Poor Access and Authorization Management

Inadequate management of access rights jeopardizes both organizational security and operational continuity. On the security front, poorly controlled permissions open pathways for insider threats, data breaches, and regulatory violations. For example, excessive privileges enable malicious insiders or negligent employees to access, modify, or delete sensitive data, risking significant financial and reputational damage. Attackers exploiting permissions gaps can also initiate lateral movement within networks, escalating privileges to compromise entire systems.

From a business perspective, improper access management can disrupt workflows, impair regulatory compliance, and lead to legal liabilities. For instance, failure to enforce segregation of duties may result in fraudulent activities or regulatory penalties under SOX; similarly, failure to timely revoke access after employee departures can enable ongoing unauthorized data exposure. These risks highlight the importance of implementing organized, role-based access controls (RBAC), continuous monitoring, and automated provisioning and de-provisioning processes.

Stakeholders and Activities Involving Access

Key stakeholders include employees, managers, IT administrators, compliance officers, and external partners. Each group interacts with organizational data and resources differently:

• Employees: Need role-based access to perform job functions, including database access, application use, and communication tools.
• Managers: Approve access requests, oversee role changes, and enforce policy adherence.
• IT Administrators: Manage user accounts, configure access controls, monitor system logs, and respond to security incidents.
• Compliance Officers: Ensure access controls meet regulatory standards and perform audits.
• External Partners: Require limited, time-bound access to specific resources, necessitating secure provisioning
• .

All these activities depend on a clear understanding of user roles, access needs, and security policies to prevent unauthorized data exposure while enabling efficient operations.

Conclusion

In sum, the risk assessment process for GlobalTech Solutions centers on identifying vulnerabilities within the existing identity and access management practices. By systematically evaluating threats, weaknesses, and controls, the organization can prioritize mitigation strategies aligned with business objectives. Collaboration across departments, enforcement of best practices like least privilege and segregation of duties, and leveraging automated tools are essential to reducing security risks and fostering a resilient, compliant enterprise environment.
