# Incident Handling Process

Now that we are familiar with the cyber kill chain and its stages, we can better predict/anticipate the next steps in an attack and suggest appropriate countermeasures.

Just like the cyber kill chain, incident response follows a structured process. The **incident handling process** helps organizations **prepare, detect, and respond** to security events. However, its stages do not correspond directly to the cyber kill chain stages.

***

## **Stages of the Incident Handling Process**

According to **NIST**, the incident handling process consists of four distinct stages:

1. **Preparation**
   * Organizations establish security policies, train employees, and implement monitoring tools.
   * This is a continuous process to improve defenses and readiness.
2. **Detection & Analysis**
   * Security teams detect potential incidents using logs, alerts, and anomaly detection.
   * Proper analysis ensures accurate classification of incidents.
3. **Containment, Eradication & Recovery**
   * Contain the threat to prevent further damage.
   * Eradicate malware and compromised accounts.
   * Recover systems to resume normal operations.
4. **Post-Incident Activity**
   * Conduct lessons learned meetings.
   * Improve defenses based on findings.
   * Document the full incident report.

## **Key Points to Remember**

* Most time is spent in **Preparation** and **Detection & Analysis** stages.
* The process is **cyclic, not linear**, meaning new evidence can shift priorities.
* Skipping steps can lead to incomplete containment and tip off attackers.
* So, incident handling has two main activities, which are investigating and recovering.
* **Investigation** focuses on identifying patient zero, adversary tools, and compromised systems.
* **Recovery** ensures business continuity with a structured remediation plan.
* Final **reports** and **lessons learned** help prevent future incidents.

## **Quiz**

1. What is the primary goal of the incident handling process?

   * a) To document all security incidents
   * b) To prepare, detect, and respond to malicious events
   * c) To track all network activity
   * d) To prevent hackers from scanning the network

2. Which of the following is NOT a stage of the incident handling process?

   * a) Detection & Analysis
   * b) Preparation
   * c) Lateral Movement
   * d) Post-Incident Activity

3. What is the main focus during the Preparation stage?

   * a) Blocking all external traffic
   * b) Training employees, setting policies, and implementing security tools
   * c) Investigating attack sources
   * d) Removing malware from infected machines

4. Why is skipping steps in the incident handling process dangerous?

   * a) It saves time but reduces the efficiency of the recovery process
   * b) It can alert the attacker that they have been detected
   * c) It allows security teams to move faster
   * d) It helps contain the incident immediately

5. What is the purpose of post-incident activities?
   * a) To determine if an attack is still ongoing
   * b) To learn from the incident and improve security measures
   * c) To track attacker activity in real-time
   * d) To restore systems after an incident

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://digitalgarden.batamladen.com/notes/certificates/cdsa/module-1-incident-handling/incident-handling-process.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
