Document Information
- Title: Computer Security Incident Handling Guide
- Revision: 2
- Publication: NIST Special Publication 800-61
- Authors: Paul Cichonski, Tom Millar, Tim Grance, Karen Scarfone
- Date: August 2012
- DOI: http://dx.doi.org/10.6028/NIST.SP.800-61r2
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.
