CISSP PRACTICE QUESTIONS – 20220104

Effective CISSP Questions

Assurance is the outcome of activities that decrease doubts and increase confidence. Which of the following provides the highest level of assurance? (Wentz QOTD)
A. Self-declaration
B. Attestation
C. Audit
D. Verification and Validation (V&V)

Kindly be reminded that the suggested answer is for your reference only. It doesn’t matter whether you have the right or wrong answer. What really matters is your reasoning process and justifications.

My suggested answer is C. Audit.

Wentz’s book, The Effective CISSP: Security and Risk Management, helps CISSP and CISM aspirants build a solid conceptual security model. It is a tutorial for information security and a supplement to the official study guides for the CISSP and CISM exams and an informative reference for security professionals.

Assurance, Attestation, and Audit

Auditing, Attestation, and Assurance by Edspira

While there is no such thing as a SOC 2 certification, many still refer to a clean SOC 2 report as a certification. A SOC 2 is actually an attestation report. A CPA firm attests that controls are in place and either designed effectively (Type I SOC 2), or designed effectively and operated effectively over a period of time (Type II SOC 2). Management asserts that controls are in place to meet the SOC 2 criteria and a CPA firm provides an opinion on whether or not they agree with management’s assertion.

In many cases, the opinion is positive and the CPA firm agrees with management’s assertion. In some cases, the CPA firm does not agree with management’s assertion and provides a qualified or adverse opinion. See this past blog post on qualified opinions. Although a SOC 2 is technically an attestation report, it’s very common for people to call a SOC 2 a certification. See the AICPA page related to attestation reports for more information.
