3. OPERATIVE CLAUSES & TERMS

SECTION 1: PURPOSE AND OBJECTIVES

1.1 Mandatory Scope. This Plan applies universally to all employees, contractors, temporary workers, third-party vendors, and executive leadership operating Company-owned or bring-your-own-device (BYOD) hardware connected to the Company network. 1.2 Operational Objectives. The primary objectives of this Plan are to:

• Minimize the duration, scope, and impact of any Incident.
• Preserve forensic integrity and chain of custody for legal and regulatory proceedings.
• Ensure timely, legally compliant notification to affected internal stakeholders, regulatory bodies, and external data subjects.
• Restore normal operational capability with optimized speed and minimized risk of reinfection.

SECTION 2: INCIDENT RESPONSE TEAM (IRT) & GOVERNANCE

2.1 Composition of the IRT. The Incident Response Team shall consist of pre-designated leads from the following functional domains:

• Executive Lead: Chief Executive Officer ([Name]) or designated board representative.
• Technical Lead: Chief Information Security Officer (CISO) or Director of IT ([Name]).
• Legal Lead: General Counsel or External Privacy Counsel ([Name]).
• Communications Lead: Director of Corporate Communications ([Name]).
• Operations/HR Lead: Chief Human Resources Officer ([Name]).

2.2 Command Authority. Upon the declaration of a Severity Level 1 or 2 Incident, the IRT Technical Lead assumes immediate operational command over all Company IT assets, with the explicit authority to isolate networks, sever internet connections, and disable user credentials without prior notice.

SECTION 3: INCIDENT SEVERITY CLASSIFICATION

Incidents shall be categorized into one of three operational tiers upon discovery: 3.1 Severity 3 (Low / Minor): Localized malware containment on a single workstation; unauthorized access attempts successfully blocked by perimeter defenses. Action: Handled via standard IT helpdesk ticketing; documented in weekly security logs. 3.2 Severity 2 (Medium / Moderate): Unauthorized access to non-critical internal file shares; targeted phishing campaign affecting multiple employees without credential harvesting; isolated operational disruption. Action: Immediate escalation to IRT Technical Lead; containment initiated within 4 hours. 3.3 Severity 1 (High / Critical - Data Breach/Ransomware): Confirmed deployment of ransomware; unauthorized exfiltration of sensitive PII/PHI, intellectual property, or financial records; complete outage of Critical Systems. Action: Immediate assembly of full IRT; activation of external forensics and legal counsel within 1 hour.

SECTION 4: PHASES OF INCIDENT RESPONSE

The lifecycle of an Incident shall strictly follow the National Institute of Standards and Technology (NIST) Special Publication 800-61 framework, executed in four sequential phases:

4.1 Phase 1: Preparation

• Conduct quarterly vulnerability scans and annual penetration testing.
• Maintain updated system architecture diagrams, asset inventories, and offline immutable backups of Critical Systems.
• Ensure all employees undergo mandatory annual cybersecurity awareness training.

4.2 Phase 2: Detection and Analysis

• Continuous monitoring via Endpoint Detection and Response (EDR) and Security Information and Event Management (SIEM) platforms.
• Any employee identifying an anomaly (e.g., unexpected screen locking, encrypted files, unfamiliar outbound network traffic) must immediately report it to [Security Operations Center / Email] via [Phone Number].
• The IRT Technical Lead shall triage the alert, verify IoCs, and assign a Severity Classification.

4.3 Phase 3: Containment, Eradication, and Recovery

• Containment: Isolate compromised hosts by disconnecting network cables or utilizing remote network isolation capabilities to prevent lateral movement.
• Eradication: Identify and eliminate root causes of the Incident (e.g., removal of malicious payloads, patching vulnerabilities, revoking compromised authentication tokens, resetting administrative passwords).
• Forensic Preservation: Capture volatile memory (RAM), disk images, and system logs while maintaining a strict chain of custody log ([Attachment A]).
• Recovery: Restore systems from verified clean backups, validate system integrity, and gradually reintroduce assets to the production network under heightened monitoring.

4.4 Phase 4: Post-Incident Activity (Lessons Learned)

• Within [Five (5)] business days following the resolution of a Severity 1 or 2 Incident, the IRT shall convene a Post-Mortem review meeting.
• Draft a comprehensive Incident Report detailing the timeline, root cause, impact assessment, and remediation measures implemented.
• Update security controls, policies, and training modules to prevent recurrence.

SECTION 5: REGULATORY NOTIFICATION & PUBLIC RELATIONS

5.1 Legal Review. No external communications, public statements, or regulatory notifications shall be dispatched without the explicit prior written approval of Designated Legal Counsel. 5.2 Regulatory Timelines. The Legal Lead shall oversee compliance with statutory breach notification windows (e.g., 72 hours for GDPR, state-specific timelines for US breaches). 5.3 Internal Communications. The Communications Lead shall issue controlled, factual updates to employees as directed by the Executive Lead to prevent panic and unauthorized disclosures.
