### Introduction to Security Risk Assessment

In today's digital landscape, especially within the financial services sector, a robust security risk assessment is paramount. The essence of such an assessment lies in identifying and mitigating potential risks that could lead to substantial financial losses, reputational damage, or regulatory penalties. A structured risk management program serves as the backbone of a financial organization, ensuring that vulnerabilities are addressed proactively. Key elements of a risk management program include risk identification, risk evaluation, risk treatment, and continuous monitoring. By integrating these elements, organizations can make informed decisions about resource allocation, thus reinforcing their security posture (Grobler, 2018).

The benefits derived from an effective risk management strategy extend beyond compliance. They encompass improved operational efficiency, enhanced stakeholder confidence, and a reduction in incidents that could disrupt business continuity. In the context of NCU-FSB, implementing a comprehensive risk management program is critical to safeguarding its operations and customer trust.

### Solutions to Employee Collusion

Employee collusion poses a significant threat, particularly in financial organizations where trust and integrity are paramount. To mitigate this risk, several strategies can be employed. First, implementing robust internal controls that include clear policies regarding dual authority can deter collusion by ensuring that no single employee can execute a transaction without oversight (Knight, 2017). Techniques such as transaction monitoring systems can also help identify anomalies that may indicate collusion.

Training and awareness programs can further educate employees about the ethical implications of collusion and the repercussions of violating company policies. Additionally, establishing an anonymous reporting mechanism could encourage employees to report suspicious behavior without fear of retaliation.

### Addressing Segregation of Duties (SoD) Issues

Segregation of duties (SoD) is a fundamental principle that reduces the risk of fraud and error. In compliance with regulations such as the Sarbanes-Oxley Act (SOX) and the Gramm-Leach-Bliley Act (GLBA), it is vital for financial institutions to segregate duties and rotate tasks among employees. This can be achieved by defining roles and responsibilities clearly and ensuring that multiple employees are involved in critical processes (Elnagy et al., 2016).

Given budgetary constraints that limit staffing, cross-training existing employees in multiple functions can be an effective solution. This strategy enables flexibility while adhering to SoD principles. Additionally, periodic audits and reviews can help ensure compliance with these guidelines, further reducing the risk of collusion.

### Changes to Server Settings and Configuration

To address MAC address collisions and prevent server compromises, several actions should be taken. First, implementing VLANs (Virtual Local Area Networks) can help isolate traffic and reduce the likelihood of MAC address conflicts between devices (Tokunaga, 2017). Network segmentation is crucial in this regard, providing a layered security approach that mitigates the impact of potential breaches.

Regularly updating and patching server operating systems is necessary to address vulnerabilities that could lead to exploitation. Configuring firewalls to restrict incoming and outgoing traffic based on predefined rules can also prevent unauthorized access to critical servers. Implementing comprehensive logging and monitoring systems will enable real-time detection of anomalies that may indicate a server compromise.

### Current Threat Landscape and Security Strategies

Enterprises today face several primary threats, including ransomware attacks, phishing schemes, and insider threats. The impact of these threats can be devastating, leading to financial loss and damages to reputation. A proactive security stance is required to combat these challenges (Grobler, 2018).

Comprehensive security strategies must integrate advanced threat detection systems, employee training, and incident response plans. Continuous assessment of the security landscape is also essential, allowing organizations to adapt to emerging threats. Collaboration with external cybersecurity experts can further enhance the effectiveness of security measures.

### Regulatory Compliance and Security Risk Analysis

Adhering to regulatory requirements is a vital aspect of security risk analysis. Various regulations necessitate ongoing risk assessments to protect sensitive data. Institutions like NCU-FSB must ensure compliance with regulations such as SOX and GLBA, which demand stringent measures for data protection and risk management.

### Taxonomy of Risk Elements for Cyber-Risk Management

Taxonomy refers to the classification of concepts or entities in a hierarchical structure. In the context of risk management, a well-defined taxonomy of cyber risks aids organizations in systematically identifying and evaluating risks associated with information security (Elnagy et al., 2016). Establishing a taxonomy allows for better communication about risks and facilitates the development of targeted mitigation strategies.

Additionally, using relational diagrams aids in visually conveying complex relationships among risk factors, enhancing stakeholder understanding. The inclusion of such tools in the risk assessment process is vital for effective decision-making and strategy development.

### Information Needed to Initiate a Security Risk Analysis

Initiating a security risk analysis requires gathering relevant data and establishing a well-defined flowchart for the eDiscovery process. Key information includes asset inventories, existing security policies, incident history, and threat intelligence data. A flowchart that outlines the steps involved in data collection, analysis, and reporting should be developed to ensure systematic execution of the risk analysis process.

In conclusion, as the new ISM of NCU-FSB, addressing the identified vulnerabilities and threats through a structured risk management strategy is critical. By focusing on the elements discussed, the organization can bolster its security posture and protect its valuable assets and clientele.
