## 1. OBJECTIVE & SCOPE

This Incident Response Plan (IRP) establishes a structured framework to detect, contain, investigate, and recover from cybersecurity incidents. 

This plan applies to all information systems, networks, physical locations, and personnel (including employees, contractors, and third-party partners) associated with **[Company Name]**.

## 2. INCIDENT RESPONSE TEAM (IRT) ROLES

In the event of a suspected or active security incident, the Incident Response Team (IRT) is activated. The following roles define key responsibilities:

| Role | Responsibility | Primary Contact | Secondary Contact |
| :--- | :--- | :--- | :--- |
| **Incident Commander** | Coordinates the response, authorizes containment, and leads daily briefings. | [Name/Title] | [Name/Title] |
| **Technical Lead** | Directs forensic collection, log analysis, containment, and system recovery. | [Name/Title] | [Name/Title] |
| **Legal Counsel** | Advises on regulatory disclosure, data breach notification, and liability risk. | [Name/Title] | [Name/Title] |
| **Communications Lead**| Manages internal and external communications, media statements, and alerts. | [Name/Title] | [Name/Title] |
| **Executive Sponsor** | Authorizes critical business decisions (e.g. system shutdowns, insurance claims). | [Name/Title] | [Name/Title] |

## 3. INCIDENT CLASSIFICATION LEVELS

Security incidents are categorized to determine the level of response and escalation required:

* **Low (Level 3):** Isolated events with minimal operational or security impact (e.g., single adware infection, minor policy violation).
  * *Response:* Handled by standard IT support tickets during business hours.
* **Medium (Level 2):** Incidents affecting multiple systems or sensitive data but contained (e.g., suspected phishing campaign, unauthorized logins, lost laptop).
  * *Response:* Triggers IRT notification and technical investigation.
* **High (Level 1):** Critical events causing active operational disruption or massive data exposure (e.g. active ransomware, suspected database exfiltration, total DDoS).
  * *Response:* Immediate emergency activation of the full IRT and external advisory contacts.

## 4. INCIDENT RESPONSE LIFECYCLE

### Step 1: Identification & Escalation
1. **Reporting:** Any employee or automated alert detecting suspicious activity reports it to **[Notification Email/Hotline]**.
2. **Triage:** Technical staff review log sources to verify the alert is a true incident.
3. **Escalation:** If verified, the Technical Lead notifies the Incident Commander to classify the event and activate the IRT.

### Step 2: Containment
1. **Network Isolation:** Disconnect compromised devices from local network and Wi-Fi. Do **not** power down devices if active malware/ransomware is suspected, as volatile RAM memory must be preserved.
2. **Access Control:** Revoke compromised user credentials and block malicious IP addresses at the firewall.
3. **Evidence Preservation:** Document all containment actions with exact timestamps. Ensure no logs or files are deleted.

### Step 3: Investigation (Forensics)
1. **Forensic Imaging:** Certified examiners make bit-stream clones of the affected drives using write-blockers.
2. **Log Audit:** Analyze setup logs, Setupapi histories, VPN logins, and cloud auditing records to determine root cause and timelines.
3. **Scope Analysis:** Identify what data was accessed, modified, or exfiltrated.

### Step 4: Eradication & Recovery
1. **Malware Removal:** Wipe affected drives and reinstall operating systems from clean gold-images.
2. **Credential Reset:** Force password resets and mandate new MFA matching values for all affected users.
3. **Restoration:** Methodically restore systems from offline, verified backups. Monitor network traffic for residual threat activity.

### Step 5: Post-Incident Review (Lessons Learned)
Within 10 business days of incident closure, the IRT holds a debriefing meeting:
* What went well, and what failed in the response?
* What vulnerabilities were exploited, and what controls must be implemented to prevent recurrence?
* Update the IRP documentation based on lessons learned.

## 5. EXTERNAL EMERGENCY CONTACTS

In a Level 1 (High) incident, coordinate with these external providers immediately:

* **Cyber Insurance Carrier:** [Provider Name / Policy # / Phone]
* **External Forensics / IR Firm:** [Provider Name / 24/7 Hotline]
* **Regulatory Authorities:** [Relevant State/Federal Agencies]
* **Law Enforcement (FBI Cyber Division):** [Local Office Contact]
