Incident Response Fundamentals
Incident Response Fundamentals refer to the essential principles and practices involved in identifying, managing, and resolving security incidents within an organization. This includes preparing response plans, detecting threats, containing and eradicating malicious activities, recovering affected systems, and learning from incidents to improve future responses. Effective incident response minimizes damage, reduces recovery time and costs, and helps protect sensitive data and organizational reputation.
