What Is NIST Incident Response?

NIST Incident Response is a comprehensive framework designed by the National Institute of Standards and Technology (NIST) to help organizations effectively and efficiently tackle cybersecurity incidents.

This framework is based on the NIST Special Publication 800-61, which outlines the essential steps and processes for addressing cyber threats.1 NIST Incident Response is built upon four key phases: Preparation, Detection & Analysis, Containment, Eradication & Recovery, and Post-Incident Activity.

Role Of An Incident Response Team

An incident response team is essential for detecting, containing, and mitigating security incidents while ensuring a smooth recovery for the organization. The team is responsible for creating and executing an incident response plan, educating the organization on its importance, and addressing the risks of inadequate responses.

Composed of security-savvy individuals with incident response experience, the team should be well-versed in the organization’s security policies and procedures and have access to IT systems and networks for effective investigation and response.

The team’s main tasks include swiftly identifying the incident source, determining its scope, and deciding on the best course of action for containment and mitigation. They should also provide recommendations for incident response and future prevention while supporting staff and customers during security incidents.

Importance Of Incident Response

Incident response is a vital component of an organization’s cybersecurity program, involving the management and mitigation of security breaches or attacks. A successful incident response plan should encompass:

Clear roles and responsibilities: Define who is accountable for responding to security incidents and how they will coordinate efforts.
Established processes and procedures: Implement well-defined processes for incident identification, severity assessment, and appropriate response.
Access to necessary resources: Ensure the availability of personnel, technology, and external partners for incident response.
Communication plan: Develop a strategy to inform stakeholders about the incident and its progress.
Documentation: Record the incident response process, detailing steps taken, decisions made, and outcomes to learn from past experiences and improve the plan.

An up-to-date, regularly tested incident response plan is crucial for organizations to respond swiftly and effectively to security incidents, minimizing damage and ensuring business continuity.

Why Is NIST Providing Incident Response Recommendations?

The National Institute of Standards and Technology (NIST) is a non-regulatory agency under the US Department of Commerce that fosters innovation and industrial competitiveness. Among its offerings are technical standards and guidelines, including the NIST Incident Response framework, which assists organizations in effectively addressing security incidents.2

NIST Incident Response aims to provide best practices and processes for identifying, containing, and eliminating threats swiftly and effectively while minimizing long-term risks. Adhering to the framework’s steps ensures preparedness for any security incident.

Organizations can bolster their security posture by following the NIST Incident Response recommendations, ensuring effective and efficient responses to various security incidents. Additionally, the framework supports the development of a tailored incident response plan, reducing the risk of long-term damage.

Benefits of Incident Response Plan

A comprehensive incident response plan is beneficial for organizations of all sizes, as it enables prompt and efficient responses to security incidents, reducing the impact and damage caused. The primary advantages of implementing a NIST incident response plan include:

Enhanced Security Posture: NIST guidelines help organizations identify and address potential threats in a timely manner, maintaining a secure environment and lowering the risk of breaches.
Faster Incident Response: With a structured plan, organizations can react to incidents more quickly and effectively, minimizing the impact and damage.
Better Collaboration: The NIST framework fosters a cooperative environment for incident response, streamlining efforts and involving the right personnel in the process.
Increased Compliance: Adopting a NIST incident response plan aids in meeting regulatory and compliance requirements, demonstrating a commitment to security and proper data protection measures.
Well-documented Processes: A NIST plan ensures organizations document their incident response processes, verifying adherence to the right steps and actions for data protection.

NIST Incident Response Framework Steps

The NIST Incident Response Framework is a comprehensive set of guidelines for organizations to follow when responding to security incidents. It outlines the key steps of incident response and provides recommendations on how to manage them effectively.

Step #1: Preparation

The first step in the NIST Incident Response framework is preparation. This crucial phase involves assembling an incident response team, formulating a plan, and setting up policies and procedures.

The incident response team should consist of members from various departments, such as IT, legal, and HR. They must be well-versed in the incident response plan, which outlines steps, procedures, roles, responsibilities, escalation processes, and reporting guidelines.

Organizations need to establish policies and procedures that ensure adherence to the incident response plan. These may include data security, access, and retention policies.

Moreover, it’s essential to equip the incident response team with the necessary tools, resources, and access to software, hardware, and personnel.

By preparing for incidents, organizations can guarantee their response team’s ability to tackle security incidents quickly and effectively.3

Step #2. Detection & Analysis

The second step in the NIST Incident Response framework is detection and analysis, which focuses on identifying, examining, and addressing security incidents. This stage entails gathering incident information, assessing severity and scope, and deciding on the appropriate response.

First, collect information on the incident, such as system and network data and logs, and other relevant data from affected and potentially involved systems. Next, analyze the data to determine incident severity, scope, type, potential impact, and source, whether it’s an external attack or an internal issue.

Determine the appropriate response by identifying the best course of action to mitigate the incident, like implementing additional security measures or restoring systems. Decide if reporting the incident to law enforcement or other authorities is necessary.

Finally, implement the response, including necessary security measures and system restoration. Monitor the affected systems to confirm incident resolution and prevent further incidents.3

Step #3. Containment, Eradication, & Recovery

Containment, eradication, and recovery is the next critical step in the NIST incident response framework.

Containment focuses on isolating the incident to prevent it from spreading. Identify affected systems and networks, separate them from the rest of the network, and implement security measures to stop further spread. Ensure access to the affected systems and networks is restricted.
Eradication involves removing malicious code or activity and restoring the system to its original state. Analyze the incident, identify the malicious components, and remove them. Ensure that any affected data or files are restored to their original state.
Recovery requires restoring lost or damaged data, and system functionality, and confirming incident resolution. Ensure lost or damaged data is restored, system functionality affected by the incident is recovered, and the affected system or network is secure.

Step #4. Post-Incident Activity

After containing, eradicating, and completing the recovery process, the incident response team should focus on post-incident activities such as evidence collection, post-incident review, and implementing corrective actions.

The team should first collect evidence, like logs and network traffic, to investigate the incident thoroughly. Next, they must conduct a post-incident review to discuss the incident, how it was handled, and any potential improvements to prevent similar events in the future.

Finally, the incident response team should implement corrective actions, such as updating security policies, introducing new technologies, and training employees on security best practices. These actions help reduce the risk of future incidents.3
