Legal Review in Incident Response

Legal experts must review incident response plans to ensure compliance with laws and guidelines, especially privacy rights. Seeking legal counsel is crucial if an incident has legal implications, like evidence collection or lawsuits.

Public Affairs in Incident Response

Depending on the incident's nature and impact, it might be necessary to inform the media and public.

Human Resources Role

HR gets involved if an employee is suspected of causing an incident, often supporting disciplinary actions.

Business Continuity, Incident Response

Incident response procedures and business continuity plans must align. Business continuity professionals play a crucial role in minimizing disruption caused by security incidents.

Abstract

  • Computer security incident response is a vital component of IT programs.
  • Effective incident response needs planning and resources.
  • This publication offers guidelines for incident handling, regardless of platform, operating system, protocol, or application.

Introduction

  • Authority: Developed by NIST under the Federal Information Security Management Act (FISMA).
  • Purpose: To provide practical guidelines for effectively handling computer security incidents.
  • Scope: Focuses on detecting, analyzing, prioritizing and handling incidents.
  • Audience: Intended for CSIRTs, administrators, security staff, CISOs, CIOs, and others involved in incident preparation or response.

Organizing a Computer Security Incident Response Capability

  • Definition of "incident": Organizations must precisely define "incident" to establish clear expectations.
  • Need for incident response: Cybersecurity threats are frequent, diverse, and impactful, requiring dedicated response capabilities.
  • Incident response capabilities: Involve planning and procedure creation. Effective communication with internal and external teams is critical.

Events and Incidents

  • Event: Any observable occurrence within a system or network.
  • Incident: A violation or imminent threat of a violation of computer security policies, or standard security practices.

Incident Response Policy, Plan, and Procedure Creation

  • Policy elements: Statement of management commitment; purpose & objectives; scope; definitions; roles/responsibilities; communication procedures
  • Plan elements: Mission; strategies and goals; senior management approval; incident response team structure and communication plan; roadmap for future improvements in incident handling capabilities.
  • Procedure elements: Standard operating procedures (SOPs) that detail the precise technical implementation of policies.

Sharing Information With Outside Parties

  • Important to communicate with outside entities: Law enforcement, media, other organizations.
  • Prioritization: The incident response teams need to prioritize the handling of incidents based on criteria such as the functional impact, information impact, and recoverability from the incident.

Incident Response Team Structure

  • Team Models: Central, Distributed, Coordinating.

Incident Response Team Services

  • Intrusion detection: Early detection of potential incidents.
  • Advisory Distribution: Advising on security vulnerabilities and threats.
  • Education and awareness programs: Educating users and staff on security measures.

Handling an Incident

  • Preparation: Establishing an incident response capability and preventing incidents.
  • Detection and Analysis: Identifying possible incidents (precursors and indicators) and analyzing them to determine the impact.
  • Containment, Eradication, and Recovery: Containing the damage, removing malware, and restoring systems to normal operations.
  • Post-Incident Activity: Learning from the incident and improving overall security mechanisms.
