PECB ISO-IEC-27035-Lead-Incident-Manager Exam With Confidence Using Practice Dumps

Comprehensive and Detailed Explanation From Exact Extract:

Improving controls in incident management is a proactive activity focused on directly adjusting and strengthening existing defenses. As per ISO/IEC 27035-2:2016, Clause 7.4, this process typically involves identifying deficiencies, updating or implementing new technical or procedural controls, and revising policies.

While risk assessments inform control decisions, simply documenting their results does not constitute direct improvement of controls. Hence, Option A is not part of the control improvement process itself.

Comprehensive and Detailed Explanation:

According to ISO/IEC 27035-2:2016, incident response exercises (including simulations such as phishing campaigns) must be carefully controlled to avoid confusion, escalation, or reputational damage. If an exercise is misunderstood by employees or external parties, it could lead to unintended consequences including external escalation, customer concern, or media involvement.

The best practice is to ensure that all involved—especially external stakeholders—are informed as soon as possible if they are exposed to simulated elements. Transparency ensures the organization maintains trust and mitigates potential fallout. This is part of effective communication during planned exercises.

Comprehensive and Detailed Explanation From Exact Extract:

ISO/IEC 27035 strongly encourages information sharing among trusted parties to enhance collective incident response capabilities and reduce the broader impact of cyber threats. Clause 6.5.6 in ISO/IEC 27035-1 highlights the importance of cooperation and communication with external parties, including industry-specific information-sharing forums, CERTs/CSIRTs, and trusted partners.

The practice of proactive information exchange allows organizations to:

Detect coordinated or widespread attacks

Accelerate response through shared indicators of compromise (IOCs)

Benefit from collective intelligence and incident analysis

Build sector-wide resilience

However, such exchanges must occur within well-defined protocols that preserve confidentiality, legal compliance, and operational integrity.

Option B and C reflect overly cautious or siloed approaches that may delay response or reduce the effectiveness of collaborative efforts.

Reference Extracts:

ISO/IEC 27035-1:2016, Clause 6.5.6: “Incident management should consider the importance of trusted collaboration, sharing of incident information, and threat intelligence between relevant entities.”

ENISA and FIRST.org also support this collaborative approach in their best practices.
