Which of these is a major part of incident response?

Forensics analysis is a major part of incident response because it involves the systematic examination and evaluation of data collected from various sources after a cybersecurity incident has occurred. This process helps cybersecurity professionals understand the nature of the breach, how it occurred, and the extent of the damage. Forensics analysis is crucial for identifying the vulnerabilities that were exploited by attackers and for gathering evidence, which may be essential for legal actions or reporting requirements. It provides insights that are essential for improving security measures and preventing future incidents.

The other options, while important in different contexts, do not directly contribute to incident response. Market research and trends, for instance, focus on understanding market dynamics and consumer behavior rather than managing cybersecurity incidents. Software development relates to creating applications and systems but doesn't address how to deal with incidents after they occur. Employee training programs are vital for enhancing overall security awareness and preparedness, but they are more proactive measures than reactive forms of incident response.
