Paper For Above instruction

Risk assessment is an essential component of information security management, providing a structured approach to identifying, analyzing, and evaluating risks to organizational assets. To conduct an effective risk assessment, it is crucial to select an appropriate framework that guides the process and ensures comprehensive coverage of potential threats and vulnerabilities. The NIST Special Publication 800-30 Revision 1 offers a well-established framework that aligns with best practices in risk management, emphasizing a systematic approach to assessing threats, vulnerabilities, likelihood, and impact.

Risk Assessment Framework: NIST 800-30 Revision 1

The NIST SP 800-30 Revision 1 framework delineates a series of steps designed to facilitate thorough risk assessments within federal agencies and organizations alike. It begins with preparation, where scope and purpose are defined, and then moves to risk identification, where threats and vulnerabilities are systematically identified. The framework emphasizes the importance of understanding organizational impact, likelihood, and risk levels, which are quantified through qualitative and quantitative measures. It advocates for documenting findings, prioritizing risks, and recommending control measures accordingly.

Specifically, NIST 800-30 adopts a risk-based approach that considers both the probability of threat occurrence and the potential consequence to organizational assets. It encourages organizations to develop a risk matrix that categorizes risks into levels such as low, moderate, or high, facilitating the prioritization of controls and mitigation strategies. This structured method ensures that all pertinent factors, including threat sources, vulnerabilities, and existing controls, are considered in a cohesive manner.

Furthermore, the framework underscores the importance of ongoing risk monitoring and reevaluation, recognizing that threats evolve and controls must adapt accordingly. Its flexibility allows organizations to tailor assessments to specific contexts and assets, making it an adaptable tool for diverse operational environments.

Conducting the Risk Assessment

Based on the provided evidence, the risk assessment considers several organizational vulnerabilities that could compromise the security of sensitive business data stored on local servers within a single building. The assessment addresses threats such as unauthorized access, data breaches, insider threats, and loss of data integrity, alongside vulnerabilities like weak password policies, lack of password changes, ineffective user account management, absence of off-site backups, and physical security risks associated with centralized server storage.

Threats and Vulnerabilities:

• Password Policy Weakness: The minimum password length of six characters is insufficient according to best practices, which recommend at least 12 characters with complexity requirements. This vulnerability can be exploited via brute-force or dictionary attacks, especially since passwords are not mandated to be changed regularly. Thus, attackers may gain unauthorized access through password guessing (Menn et al., 2017).
• User Account Management: The failure to delete accounts of departed employees creates vulnerabilities by allowing former staff indefinite access, increasing insider threat risks and unauthorized data exposure. This vulnerability is compounded by the lack of account review and de-provisioning policies (Anderson et al., 2020).
• Storage of Sensitive Data on Local Servers: Localized storage in a single building increases physical security risks, especially without adequate controls. Theft, physical tampering, or natural disasters could compromise data availability and integrity (Chen & Zhao, 2018).
• No Backup Strategy: The absence of backups means data loss risks are heightened. In the event of hardware failure, malware attack, or physical damage, data could be permanently lost, significantly impacting business operations (Rittinghouse & Ransome, 2017).

Risk Levels and Scoring:

Applying qualitative scoring based on NIST guidelines, the risks are evaluated as follows:

• Password Policy Weakness: Risk level: High. The likelihood of successful brute-force attack is increased, and the potential impact of unauthorized access is significant, given the sensitivity of business records.
• User Account Management: Risk level: High. The prolonged existence of active accounts of departed employees elevates insider threat risk, with potentially severe data misuse.
• Physical Server Storage: Risk level: Moderate to High. Physical security controls are not specified; thus, theft or sabotage is possible, with high impact if data is compromised.
• No Backup: Risk level: High. Data loss from any cause could be catastrophic, with considerable operational and reputational impacts.

Quantitative scoring would classify these risks with likelihood and impact values, but qualitative analysis confirms that the highest priorities involve addressing password policies, user account termination, and backup procedures.

Recommendations for Internal Controls

Based on this risk assessment, the following internal controls should be prioritized during an IT audit:

1. Password Policy Enforcement: Implement a policy requiring minimum 12-character passwords with complexity requirements and mandatory periodic password changes to mitigate brute-force and dictionary attacks (Moore et al., 2020).
2. User Account Management Procedures: Establish strict policies for timely disabling or deleting accounts of employees who leave or change roles, including regular account reviews and audits (Alarifi & Alsevie, 2021).
3. Enhanced Physical Security: Deploy access controls, surveillance cameras, and environmental controls at the server site to prevent theft, tampering, and environmental damage (Hua et al., 2019).
4. Data Backup and Recovery: Develop and implement off-site and encrypted daily backups, with periodic testing of restore procedures to ensure data integrity and availability in case of disasters (Kumar et al., 2019).
5. Monitoring and Incident Response: Establish continuous monitoring of access logs, and set up an incident response plan to detect and mitigate unauthorized activities promptly (Zhao et al., 2022).

Addressing these controls will significantly reduce organizational risk, prevent data breaches, and ensure compliance with security standards and best practices.

Conclusion

Effective risk management requires a systematic assessment and prioritization of vulnerabilities and threats. Applying the NIST 800-30 framework facilitates a comprehensive understanding of organizational risks, guiding the development of targeted internal controls. By strengthening password policies, managing user accounts diligently, securing physical infrastructure, and implementing robust backup strategies, the organization can significantly mitigate potential security breaches and data loss, ensuring operational resilience and trustworthiness.
