Certified: The CISSP Prepcast

Welcome to The Bare Metal Cyber CISSP Prepcast. This series helps you prepare for the ISC squared CISSP exam with focused explanations and practical context.
In this episode, we focus on a critical area of cybersecurity operations—incident management, with specific attention on preparation and response. Incidents can range from malware infections and data breaches to insider threats and accidental data loss. What separates effective organizations from vulnerable ones is not the absence of incidents, but how they prepare for and respond to them. Incident management is not just a technical function. It is an organizational discipline that requires planning, coordination, and continual improvement. As a future Certified Information Systems Security Professional, you must understand the importance of readiness and structured action when security events occur.
Let us begin by understanding what incident management entails. Incident management refers to the structured processes and procedures used to detect, respond to, and recover from cybersecurity incidents. These processes are designed to minimize harm, restore operations quickly, protect assets, and ensure regulatory compliance.
Effective incident management includes everything from monitoring for early warning signs to post-incident reviews that capture lessons learned. It provides a framework for coordinated action, clear decision-making, and transparent communication during times of stress and urgency. It is about being ready—before something happens—and knowing what to do the moment it does.
Incident management minimizes impacts by containing damage early. It reduces downtime by restoring systems quickly. It preserves evidence for forensic analysis. It helps your organization meet legal and contractual obligations. And it builds trust—internally and externally—by showing that you are prepared, responsible, and in control.
When incident management is clear, structured, and practiced, organizations become more resilient. They respond faster, recover better, and learn continuously. That is the true goal of incident management—reducing harm, building strength, and continuously raising the bar.
Let us now turn to best practices for incident preparation. Preparation begins with having a documented and well-understood incident response plan. This plan should define the roles and responsibilities of the incident response team, describe escalation paths, outline communication protocols, and provide checklists for each phase of the response.
Your response plan should be tailored to your organization’s structure, systems, and risk profile. It should clearly indicate who leads the response, who communicates with stakeholders, and who handles technical containment and eradication. It should also define how to escalate issues to legal, compliance, or executive leadership.
Preparation includes regularly testing the plan. Conduct tabletop exercises to walk through response scenarios. Run simulated attacks to practice detection, containment, and recovery. These drills reveal gaps in knowledge, coordination, and procedures—while providing hands-on experience.
A formal incident response team must be established. This team should include security analysts, system administrators, network engineers, legal advisors, and communication specialists. Their responsibilities should be well-defined and supported with authority to act swiftly when needed.
Monitoring is another pillar of preparation. Deploy logging systems, S I E M platforms, endpoint detection and response tools, and intrusion detection systems. These tools allow you to detect incidents early—before the damage spreads. Logging should be continuous, centralized, and securely stored.
Finally, prepare your people. Train staff across all departments to recognize signs of incidents and know how to report them. Provide playbooks, checklists, and quick-start guides. Make sure everyone understands the importance of reporting suspicious activity and knows what to do when something goes wrong.
With preparation in place, let us now explore effective incident response strategies. Incident response typically follows five structured phases: identification, containment, eradication, recovery, and post-incident analysis.
The first phase is identification. This means detecting that an incident has occurred. Identification can come from automated alerts, manual reports, user submissions, or intelligence feeds. The goal is to determine quickly whether an event is a legitimate incident, what systems are affected, and what actions may be necessary.
Once an incident is identified, the next step is containment. This involves isolating affected systems, accounts, or services to prevent the incident from spreading. Containment may involve disconnecting systems from the network, disabling user accounts, or blocking specific ports or IP addresses. The goal is to limit the damage and stabilize the environment.
After containment comes eradication. This means removing the threat from the environment. Eradication might involve deleting malicious files, restoring clean configurations, patching vulnerabilities, or decommissioning compromised systems. You must also investigate how the threat entered and what vulnerabilities were exploited.
The fourth phase is recovery. This involves bringing affected systems back online, restoring data from backups, validating system integrity, and monitoring for signs of reinfection or ongoing compromise. Recovery must be done carefully, to avoid reintroducing the threat or rushing back into an insecure state.
Finally, the fifth phase is post-incident analysis. This includes reviewing the incident timeline, identifying lessons learned, and adjusting policies, controls, and procedures. It is an opportunity to improve, educate, and strengthen.

Let us now discuss what happens after an incident is resolved—post-incident activities. A thorough review should be conducted to document the event, evaluate the response, and identify what went well and what needs improvement.
Root cause analysis is key. Ask why the incident happened. Was it a phishing email? A missing patch? A misconfigured firewall rule? Understanding the root causes allows your organization to correct underlying issues—not just symptoms.
Document lessons learned. What gaps in detection, response, or communication were uncovered? What improvements should be made to technology, training, or processes? This documentation becomes the foundation for future enhancements and justifies changes to leadership.
Share findings with the right stakeholders. This includes internal teams, executives, regulators, and sometimes customers. Transparency builds trust and accountability. It also reinforces the importance of ongoing vigilance and continuous improvement.
Update your training programs. If the incident revealed a lack of awareness or coordination, use those insights to inform your next training cycle. Revise your incident response plan to incorporate what you’ve learned. Improve communication trees, escalation rules, or tool configurations based on real-world feedback.
Next, let’s look at the security controls that support incident management. Your environment must be equipped with strong detection capabilities. This includes S I E M systems, intrusion detection and prevention systems, and endpoint detection and response tools. These platforms help identify threats in real time.
Secure communication is essential. Incident responders must be able to communicate clearly and securely during an event. Use encrypted channels and out-of-band communication tools to coordinate actions without tipping off attackers or losing sensitive data.
Vulnerability assessments, penetration tests, and internal audits all help proactively uncover weaknesses. These findings guide hardening efforts and improve readiness. Documentation is also essential. Maintain incident logs, investigation records, and resolution details in secure storage. This supports compliance and allows for deeper forensic analysis.
Finally, enhance response with analytics and intelligence. Use real-time dashboards to track incident status. Integrate threat intelligence feeds to match observed behavior with known attacker tactics. The more informed your response team is, the more effective they will be.
Continuous improvement is what turns good incident management into great incident management. Review and refine your response plans regularly. Adjust your strategy based on new threats, changing business needs, and updated regulations.
Use metrics like Mean Time to Detect and Mean Time to Respond to evaluate performance. Compare response timelines to incident severity. Analyze detection rates, containment times, and recovery durations. Use this data to guide staffing, investments, and training.
Involve all departments. Incident management is not just a security team function—it includes operations, legal, communications, and leadership. Cross-functional collaboration ensures that your response is coordinated and effective.
Train regularly. Practice with new scenarios. Rotate leadership roles during simulations. Reinforce knowledge through tabletop exercises, threat modeling, and after-action reviews. Preparedness is not a one-time task. It is a discipline.
