An incident, in the context of information technology, is an event that is not part of the standard operation of a service and that causes, or may cause, an interruption to, or a decrease in, the quality of that service. Incidents could range from a simple overloading of the system to a full-scale cyber attack.

Incident response methodology is a structured approach to addressing and managing the aftermath of a security breach or cyber attack, also known as an incident. The goal is to handle the situation in a way that limits damage and reduces recovery time and costs.

Here is a detailed explanation of the incident response methodology:

1. **Preparation:** This is the first and most crucial step. It involves developing an incident response plan, setting up an incident response team, and ensuring all systems, processes, and personnel are ready to deal with an incident.

2. **Identification:** This step involves detecting and acknowledging that an incident has occurred. Detection can be done through system monitoring tools or through reports from users.

3. **Containment:** Once an incident has been identified, it needs to be contained to prevent further damage. This could involve isolating the affected systems or taking them offline.

4. **Eradication:** After the incident has been contained, the cause of the incident needs to be found and removed. This could involve removing malware, updating software, or changing passwords.

5. **Recovery:** In this step, systems and data are restored to normal operation, ensuring that no threats remain. This could involve restoring systems from clean backups, checking that no vulnerabilities remain, and monitoring systems for signs of recurrence.

6. **Lessons Learned:** After the incident has been dealt with, it's important to review what happened, why it happened, and how it was handled. This can help improve the incident response plan and prevent future incidents.

Remember, the key to effective incident response is preparation. Having a plan in place before an incident occurs can save a lot of time and resources when dealing with the aftermath of an incident.
