CISA Exam Dumps - Certified Information Systems Auditor

Granting access on a need-to-know basis ensures that a service provider only has the permissions necessary to perform their specific tasks. This principle minimizes the risk of unauthorized access oraccidental misuse of the system by restricting access to essential areas only. It aligns with the least privilege principle, a cornerstone of effective access control.

Limited Administrator Access with Expiration (Option A):This is helpful but does not ensure that the access granted aligns with the specific job requirements.

Deleting User IDs After Completion (Option C):This is a good practice but applies after the task, not during access.

Access Corresponding to the SLA (Option D):While important, this focuses on timeframes and does not restrict permissions effectively.

Comprehensive and Detailed Step-by-Step Explanation:

A lack ofMobile Device Management (MDM) enrollmentis the biggest concern, asunmanaged devicespose a serious security risk.

Not All Devices Enrolled in MDM (Correct Answer – C)

Unenrolled devices can bypass security policies.

Example:A stolen, unenrolled device may lack encryption, exposing corporate data.

Biometric Authentication Required (Incorrect – A)

Biometrics are anenhanced security measure, not a concern.

VPN Not Required for Internal Network (Incorrect – B)

VPNs are typically used for external access, not always needed internally.

Remote Wipe Requires Internet (Incorrect – D)

A limitation but stillless riskythan allowing unsecured devices.

Compliance testing ensures that the organization's incident response processes align with established cybersecurity frameworks and policies. This methodology provides objective and reliable conclusions about the maturity of incident response capabilities.

Judgmental Sampling (Option A):Relies on subjective judgment and is less reliable.

Data Analytics Testing (Option B):Useful for identifying trends but may not assess process maturity comprehensively.

Variable Sampling (Option C):Appropriate for statistical analysis but less effective in process maturity assessments.

Comprehensive and Detailed Step-by-Step Explanation:

Exploitationis the phase where testersleverage identified vulnerabilitiestogain unauthorized accessto systems.

Exploitation (Correct Answer – B)

Attackers use techniques such as SQL injection, buffer overflow, or privilege escalation.

Example:A tester exploits a weak password to gain admin access.

Exfiltration (Incorrect – A)

The process of stealing dataaftergaining access.

Reconnaissance (Incorrect – C)

The initial stage where attackers gather information about the target.

Scanning (Incorrect – D)

Involves identifying open ports and services but does not involve actual attacks.
