1.
An organization is preparing for an ISO/IEC 27001 certification audit.
During the Stage 1 audit, the lead auditor discovers that top management
has defined an information security policy, but there is no documented
evidence demonstrating that interested parties and their relevant
requirements were considered when determining the ISMS scope. What
is the most appropriate auditor conclusion?
A. The organization automatically has a major nonconformity because
interested parties must be listed in the information security policy
B. The auditor should determine whether the organization has
determined relevant interested parties and their requirements as required
by the ISMS context process
C. The auditor should require management to include every possible
interested party in the ISMS scope
D. The auditor should disregard the issue because interested-party
requirements are only relevant to quality management systems
Answer: B.
Rationale: ISO/IEC 27001 requires the organization to determine
relevant interested parties and their relevant requirements when
establishing the context of the ISMS. The auditor should evaluate
objective evidence showing that this determination has actually
occurred and influenced the ISMS. There is no requirement to list
every conceivable interested party in the information security policy,
1

,and the issue cannot simply be dismissed because ISO/IEC 27001
explicitly addresses interested parties.


2.
During an audit of an organization operating a cloud-based financial
services platform, the auditor discovers that the ISMS scope excludes
the organization's cloud infrastructure provider. Management explains
that because the infrastructure is outsourced, it is outside the
organization's control and therefore outside the ISMS. Which response is
most appropriate?
A. Accept the exclusion because outsourced infrastructure can never be
part of an ISMS
B. Require the cloud provider to obtain ISO/IEC 27001 certification
before the organization's ISMS can be certified
C. Determine whether the outsourced services and associated interfaces
affect the organization's ability to achieve intended ISMS outcomes and
whether they have been appropriately addressed
D. Automatically expand the ISMS scope to include the cloud provider
as though it were an internal department
Answer: C.
Rationale: Outsourcing does not automatically remove security
responsibilities from the organization. The auditor should examine
how externally provided processes, products, and services are
controlled and how their security implications are addressed. The
organization does not necessarily need to bring the provider inside its
formal ISMS scope or require the provider to possess ISO/IEC 27001
certification, but it must appropriately manage relevant risks and
interfaces.

An organization has identified ransomware as a significant information
security risk. Its risk treatment plan states that the risk will be reduced
through endpoint protection, immutable backups, privileged-access
controls, and incident response procedures. During the audit, the auditor
finds that the treatment plan has not been updated for 18 months even
though the organization's infrastructure and threat landscape have
changed significantly. What should the auditor focus on?
A. Whether the organization has maintained an effective and appropriate
risk assessment and treatment process
B. Whether ransomware is specifically listed as a mandatory ISO/IEC
27001 risk
C. Whether the organization has purchased the most expensive available
endpoint protection solution
D. Whether the organization has eliminated all ransomware risk
Answer: A.
Rationale: ISO/IEC 27001 does not prescribe a mandatory list of risks
or specific technologies. The auditor evaluates whether the
organization's risk assessment and treatment processes are
established, maintained, and appropriate to the organization's
circumstances. Significant changes in technology and threats can
provide evidence that risk information should be reviewed and
updated.


4.
A lead auditor is reviewing an organization's information security
objectives. The organization has established an objective stating,
"Improve information security." No measurement criteria, responsible


3

, personnel, timeframe, or method for evaluating achievement has been
defined. What is the strongest audit concern?
A. The objective is acceptable because ISO/IEC 27001 does not require
objectives to be measurable
B. The objective is insufficient because information security objectives
should be consistent with the policy and appropriately planned and
evaluated
C. The objective is acceptable as long as the CEO approves it
D. The organization must replace the objective with a financial objective
Answer: B.
Rationale: Information security objectives must be appropriately
established and planned. An auditor should look for evidence that
objectives are measurable where practicable, monitored,
communicated as appropriate, and updated when necessary. A vague
statement such as "Improve information security" may be useful as a
strategic aspiration but does not by itself provide sufficient evidence of
a properly managed ISMS objective.


5.
During an audit, an auditor asks the organization's Chief Information
Security Officer to demonstrate how the organization determines
whether information security risks are acceptable. The CISO provides an
undocumented verbal explanation but cannot provide approved risk
acceptance criteria. What should the auditor do first?
A. Immediately issue a major nonconformity
B. Determine whether documented risk criteria are required by the
organization's established ISMS processes and whether objective
evidence exists elsewhere
