CISM Exam Dumps - Certified Information Security Manager

The next thing an incident response team should do after establishing that an application has been breached is to isolate the impacted systems from the rest of the network, which means disconnecting them from the internet or other network connections to prevent further spread of the attack or data exfiltration. Isolating the impacted systems can help to contain the breach and limit its impact on the organization. The other options, such as maintaining the affected systems in a forensically acceptable state, conducting a risk assessment, or informing senior management, may be done later in the incident response process, after isolating the impacted systems.

= Data owner is the best suited to determine how the information in a database should be classified, because data owner is the person who has the authority and responsibility for the data and its protection. Data owner is accountable for the business value, quality, integrity, and security of the data. Data owner also defines the data classification criteria and levels based on the data sensitivity, criticality, and regulatory requirements. Data owner assigns the data custodian and grants the data access rights to the data users. Data owner reviews and approves the data classification policies and procedures, and ensures the compliance with them.

Assessing the risk of noncompliance ensures that decisions are based on an understanding of the business impact and security implications.

“Before reporting or remediating, it is critical to assess the risk associated with the control bypass to make informed decisions.”

 Information security is the most critical function when initiating the removal of system access for terminated employees, as it is responsible for ensuring that the access rights of the employees are revoked in a timely and effective manner, and that the security of the organization’s data and systems is maintained. Information security should coordinate with other functions, such as HR, legal, and help desk, to implement the access removal process, but it is the primary function that has the authority and capability to disable or delete the access credentials of the terminated employees. The other options are not as critical as information security, as they may have different roles or responsibilities in the access removal process, or they may not have direct access to the systems or tools that control the access rights of the employees. References =

CISM Review Manual 15th Edition, page 114: “Information security is responsible for ensuring that access rights are revoked in a timely and effective manner.”

SOC 2 Controls: Access Removal for Terminated or Transferred Users, snippets: “Systems access that is no longer required for terminated or transferred users is removed within one business day. For terminated employees, access to key IT systems is revoked in a timely manner. A termination checklist and ticket are completed, and access is revoked for employees as a component of the employee termination process.”

IT Involvement in Employee Termination, A Checklist, snippets: “Disable all network access. If your company uses a master access list of active passwords, tell the system to deny any passcodes associated with the user being terminated. If your system doesn’t have a deny function, delete the user and their associated passwords. Monitor employee access.”

Human resources (HR) is the most critical function when initiating the removal of system access for terminated employees because it is responsible for notifying the relevant parties, such as information security, help desk, and legal, of the employee’s termination status and date. HR also ensures that the employee’s exit process is completed and documented, and that the employee returns any company-owned devices or assets. HR also coordinates with the employee’s manager and team to ensure a smooth transition of work and responsibilities.

Comprehensive and Detailed Step-by-Step Explanation:

Risk-based vulnerability management prioritizes vulnerabilities based on the potential impact on critical assets.

A. The information available about the vulnerability: While important for assessing risk, it does not directly determine the priority.

B. The sensitivity of the asset and the data it contains: This is the BEST answer because prioritizing vulnerabilities based on the criticality of the affected assets ensures that high-impact threats are addressed first.

C. IT resource availability and constraints: These are logistical considerations but should not outweigh risk impact.

D. Whether patches have been developed and tested: Patches are important for remediation but do not determine prioritization.

The data owner is the most appropriate role to determine access rights for specific users of an application because they have legal rights and complete control over data elements4. They are also responsible for approving data glossaries and definitions, ensuring the accuracy of information, and supervising operations related to data quality5. The data custodian is responsible for the safe custody, transport, and storage of the data and implementation of business rules, but not for determining access rights4. The system administrator is responsible for managing the security and storage infrastructure of data sets according to the organization’s data governance policies, but not for determining access rights5. Senior management is responsible for setting the strategic direction and priorities for data governance, but not for determining access rights5.

A post-incident review is a process of analyzing an incident and its impact, identifying the root causes, and recommending corrective actions to prevent recurrence. The first step of a post-incident review is to perform root cause analysis, which is the process of identifying the underlying factors that contributed to the occurrence and severity of the incident. Root cause analysis helps to determine the most effective and efficient solutions to address the problem and avoid future incidents. References = CISM Review Manual, 16th Edition, Chapter 5, Section 5.5.2.11

Initiating incident response is the best course of action after a server has been attacked because it activates the incident response plan or process, which defines the roles and responsibilities, procedures and protocols, tools and techniques for responding to and managing a security incident effectively and efficiently. Reviewing vulnerability assessment is not a good course of action because it does not address the current attack or its impact, but rather evaluates the potential weaknesses or exposures of the server. Conducting a security audit is not a good course of action because it does not address the current attack or its impact, but rather verifies and validates the compliance or performance of the server’s security controls or systems. Isolating the system is not a good course of action because it does not address the current attack or its impact, but rather stops or limits any communication or interaction with the server.
