1. Purpose & Scope

This document defines the systemic approach for identifying, containing, and remediating security incidents within [Company Name] infrastructure. It applies to all employees, contractors, and third-party vendors accessing [Company Name] information assets.

2. Prerequisites

• Access to the [Secure Incident Management Portal/Tool].
• Pre-configured out-of-band communication channel (e.g., [Encrypted Messaging Platform]).
• Access to the [Company Name] network segment isolation controls.
• Hard-copy contact list for stakeholders (in case of total network failure).
• Forensic imaging tools (e.g., [Tool Name]).

3. Roles & Responsibilities (RACI)

4. Step-by-Step Procedure

Phase I: Preparation & Identification

• Monitor [Security Information and Event Management (SIEM) Tool] for anomalous activity.
• Validate incident trigger via [Verification Method].
• Log initial findings in [Incident Ticket ID].

Phase II: Containment

• Execute [Network Segmentation Protocol] to isolate affected [Server/Workstation].
• Capture volatile memory (RAM) and disk images for forensic analysis.
• Disable compromised credentials in [Identity Management System].

Phase III: Eradication

• Identify root cause using [Root Cause Analysis Framework].
• Remove malicious artifacts (e.g., malware, unauthorized access points).
• Patch vulnerabilities identified as the entry vector.

Phase IV: Recovery

• Restore services from [Verified Backup Source] dated [Date/Time].
• Verify system integrity via [Integrity Checking Tool].
• Increase monitoring sensitivity on affected systems for [Number] days.

Phase V: Post-Incident Activity

• Conduct "Lessons Learned" meeting with all stakeholders.
• Update [Incident Response Documentation] based on findings.
• Submit final report to [Executive Leadership/Board].

5. Quality Assurance, Pro-Tips, & Pitfalls

• QA Checklist: Ensure all logs are timestamped in UTC. Verify that chain-of-custody documentation is signed for all physical/digital evidence.
• Pro-Tip: Always maintain an "Out-of-Band" communication channel. If your internal email is compromised, attackers can monitor your response strategy.
• Common Pitfall: Rushing to reboot systems. Rebooting clears RAM, which often contains the only evidence of fileless malware or encryption keys.

6. FAQs

Q: When should we involve Legal Counsel? A: Immediately upon the discovery of a breach involving PII (Personally Identifiable Information) or PHI (Protected Health Information) to establish attorney-client privilege.

Q: Should we pay a ransom in a ransomware scenario? A: No. [Company Name] policy prohibits ransom payments as there is no guarantee of data recovery and it funds criminal enterprises. Consult with [Cyber Insurance Provider] before taking any action.
