Which of the following is NOT a response sub-process?

The correct understanding of the question involves identifying what constitutes a response sub-process within the framework of incident management. The response phase typically includes planning, coordination, and communication, which are essential elements for successfully addressing incidents.

Planning the response strategy is a critical sub-process; it involves developing a structured approach to addressing identified threats or vulnerabilities. It sets the foundation for how the incident will be handled.

Coordinating response refers to the organization and management of the response team and resources during an incident. This sub-process ensures that efforts are unified and efficient, leveraging the strengths of various team members and stakeholders involved.

Communicating with stakeholders is also vital. Keeping relevant parties informed throughout the incident response process ensures transparency, which is key to maintaining trust and facilitating collaboration.

In contrast, performing malware analysis, while a significant activity within incident response, is more of a technical task rather than a broader sub-process aimed at managing the overall incident response. It involves the detailed examination of malicious software to understand its impact and behavior but does not encompass the strategic or managerial aspects that are critical to coordinating an effective response. Thus, it does not fit the definition of a response sub-process in the same way that the other options do.
