Incident Management
Incident Management involves the identification, response, containment, eradication, and recovery from security events, incidents, and breaches that could affect the confidentiality, integrity, and availability (CIA) of an organization's information systems or data. These efforts require coordination between various teams, resources, and stakeholders to limit the impact of security incidents effectively, restore normal operations as quickly as possible, and ensure all pertinent lessons toward preventing future incidents can be learned. Within the security governance framework, incident management focuses on developing, implementing, and maintaining an organization-wide incident response plan that outlines roles, responsibilities, and procedures during incident handling.
Incident Management: A Guide for CISSP Studies and Exam Preparation
Incident Management is important as it helps organizations to handle unexpected events in a systematic and effective way, minimizing the disruption caused and preventing recurrence. These incidents range from critical business processes going down to network or data breaches.
What is Incident Management?
Incident Management is a term describing the activities of an organization to identify, analyze and correct hazards to prevent a future re-occurrence. These incidents within a structured organization are normally dealt with by either an Incident Response Team (IRT), an Incident Management Team (IMT), or Incident Management Service (IMS) using Incident Management Systems (IMS) to help manage the response.
How it works
The Incident management process can be broken down into several steps:
1. Incident identification
2. Incident logging
3. Incident categorization
4. Incident prioritization
5. Initial diagnosis
6. Incident escalation, if necessary
7. Incident resolution
8. Incident closure
Each process is guided by policies and procedures with the intention of restorative measures.
