Helping Hand Questions for CRISC

The best way to mitigate the risk of reputational damage from inappropriate use of social media sites by employees is to implement training and awareness programs that educate them on the acceptable andunacceptable use of social media, the potential consequences of violating the policy, and the best practices for protecting the organization’s reputation and information. Training and awareness programs can also help to foster a culture of risk awareness and responsibility among employees, and encourage them to report any incidents or issues related to social media use. References = Risk and Information Systems Control Study Manual, 7th Edition, Chapter 3, Section 3.2.4, page 131.

A security log is a record of security-related events or activities that occur in an IT system, network, or application, such as user authentication, access control, firewall activity, or intrusion detection1. Security logscan help to monitor and audit the security posture and performance of the IT environment, and to detect and investigate any security incidents, breaches, or anomalies2.

The integrity of a security log refers to the accuracy and completeness of the log data, and the assurance that the log data has not been modified, deleted, or tampered with by unauthorized or malicious parties3. The integrity of a security log is essential for ensuring the reliability and validity of the log analysis and reporting, and for providing evidence and accountability for security incidents and compliance4.

Among the four options given, the most important factor to the integrity of a security log is the inability to edit. This means that the security log data should be protected from any unauthorized or accidental changes or alterations, such as adding, deleting, or modifying log entries, or changing the log format or timestamps5. The inability to edit can be achieved by implementing various controls and measures, such as:

Applying digital signatures or hashes to the log data to verify its authenticity and integrity

Encrypting the log data to prevent unauthorized access or disclosure

Implementing least privilege access to the log data to restrict who can view, modify, or delete the log data

Using write-once media or devices to store the log data, such as CD-ROMs or WORM drives

Sending the log data to a secure and centralized log server or repository, and using syslog or other protocols to ensure secure and reliable log transmission

Performing regular backups and archiving of the log data to prevent data loss or corruption

The best way to ensure that access remains appropriate for an organization that practices the principle of least privilege is to review user access rights on a regular basis by obtaining an access control matrix and approval from the user’s manager. An access control matrix is a table that shows the access rights and permissions of each user or role for each resource or function. An access control matrix helps to verify that the users have the minimum level of access required to perform their duties, and to identify any unauthorized or excessive access rights. Approval from the user’s manager helps to confirm that the user’s access rights are consistent with their current role and responsibilities, and to authorize any changes or exceptions as needed. References = Risk and Information Systems Control Study Manual, 7th Edition, Chapter 3, Section 3.2.2, page 1281

Changes to data sensitivity during the data life cycle present the greatest risk for a global organization when implementing a data classification policy, as they may result in data being under-protected or over-protected, leading to potential data breaches, compliance violations, or inefficiencies. Data sensitivity refers to the level of confidentiality, integrity, and availability that the data requires, and it may changedepending on the data’s creation, storage, processing, transmission, or disposal. A data classification policy should consider the changes to data sensitivity during the data life cycle and ensure that the appropriate controls and procedures are applied at each stage. Data encryption not applied to all sensitive data, many data assets that need to be classified, and changes to information handling procedures not documented are not the greatest risks, as they do not affect the data classification policy itself, but rather the implementation or execution of the policy. References = CRISC Certified in Risk and Information Systems Control – Question211; ISACA Certified in Risk and Information Systems Control (CRISC) Certification Exam Question and Answers, question 211.
