Incident Response Paperusing Nists Sp 800 61 Computer Security Incid

Incident Response Paper using NIST’s SP 800-61 “Computer Security Incident Handling Guide,” develop an incident response plan (IRP) that addresses one or more security risks identified in your risk assessment. The plan should include the following sections: roles and responsibilities, training, plan testing, incident definition, incident notification procedures, reporting and tracking, lessons learned, and specific procedures for addressing a selected security risk, including preparation, detection and analysis, containment, eradication, recovery, and post-incident activities. Use actual IRPs from the internet to review structure and content, and adapt scenarios from the NIST SP 800-61 appendix to develop effective response procedures, especially for one identified risk. The paper should be 5-7 pages, well-organized, minimally error-prone, with comprehensive recovery and mission restoration guidance.

Introduction

Effective incident response planning is a critical component of an organization’s cybersecurity framework. It ensures that risks are identified, appropriate response actions are defined, and recovery procedures are established to minimize damage and restore mission-critical functions swiftly. Based on NIST Special Publication 800-61, “Computer Security Incident Handling Guide,” this paper develops a comprehensive incident response plan (IRP) addressing specific security risks identified during a prior risk assessment.

Roles and Responsibilities

An incident response team (IRT) should be designated to respond promptly to security incidents. This team typically includes cybersecurity analysts, system administrators, legal advisors, and communication personnel. Primary responsibilities involve incident detection, response coordination, and communication with stakeholders. Notification and escalation procedures must be clear; for example, minor incidents may be handled internally, whereas major breaches requiring external notification, such as to law enforcement or regulatory bodies, should be escalated accordingly.

The IRP will designate a Incident Response Coordinator (IRC) charged with leading the team and updating the plan. The plan’s development and maintenance are the responsibility of the cybersecurity manager, ensuring that procedures stay current with evolving threats.

Training and Plan Testing

Regular training sessions are vital for maintaining an effective IRP. Training should occur at least semi-annually, including simulated incident exercises, tabletop scenarios, and review of procedures to ensure preparedness. The training process enhances team coordination, identifies gaps, and reinforces response protocols.

Plan testing involves simulated incidents, such as phishing attacks or network intrusions, to evaluate effectiveness. These drills should occur at least annually, with post-test evaluations driving continual improvements.

Incident Definition and Examples

An incident is any event that compromises the confidentiality, integrity, or availability of information or systems. Examples include malware infections, unauthorized access, data leaks, and wireless access point compromise, among others. For this plan, emphasis will be placed on wireless access points, based on a scenario in NIST SP 800-61, as an identified risk.

Incident Notification Procedures

Upon detection of an incident, immediate actions include confirming the event, containing further damage, and notifying the incident response team. Communication channels should be predefined, including internal reporting mechanisms and external notifications if required (e.g., law enforcement or compliance agencies). Documentation of the incident detection and notification timeline is essential for legal and management purposes.

Reporting and Tracking

All incidents must be documented in an incident management system, capturing details such as date/time, type, scope, detection method, response actions, and resolution status. Regular review of these records will facilitate trend analysis and enhance future incident response capabilities. Lessons learned are captured through debriefings, which inform plan updates and training.

Procedures for Addressing Wireless Access Point Incidents

Considering the specific risk of unknown or malicious wireless access points, procedures are developed based on NIST Scenario 11. This scenario guides the detection, analysis, and mitigation steps necessary when an unauthorized wireless device is found.

Preparation

Preparation includes maintaining an updated inventory of authorized access points, implementing wireless intrusion detection/prevention systems (WIDS/WIPS), and establishing baseline wireless network behavior. Staff training covers how to identify suspicious wireless activity and the importance of reporting anomalies.

Detection and Analysis

Detection involves using WIDS/WIPS tools to monitor for unknown access points. Any unauthorized device discovered should be logged, including signal strength, location, and MAC address. Analysis confirms whether the access point is malicious or benign, considering historical Wireless LAN environment data.

Containment

Containment involves isolating the suspicious access point, disabling or disconnecting it, and preventing further access. Physical containment might include disabling ports or wireless interfaces, while administrative measures include alerting network administrators and temporarily suspending related network segments.

Eradication

Eradication focuses on removing the malicious device and its configuration from the network. This may involve disconnecting the device, updating wireless access controls, and conducting scans to ensure no other rogue devices remain.

Recovery and Post-Incident Activities

Recovery includes restoring wireless services using authorized access points and verifying network functionality. Post-incident activities involve analyzing the root cause, reviewing detection effectiveness, and updating policies or controls to prevent recurrence. Lessons learned are documented, and staff are retrained as necessary.

Conclusion

A well-structured incident response plan, rooted in the NIST SP 800-61 framework, ensures organizations are prepared to manage security incidents efficiently. By defining clear roles, training participants, testing procedures regularly, and establishing detailed protocols for specific risks—such as rogue wireless access points—organizations can mitigate impact, recover swiftly, and enhance overall security posture.
