ImageNet CISO](https://blog.imagenetconsulting.com/author/stephen-demsky-imagenet-ciso) - [Tweet](https://twitter.com/share) In today’s online world, it feels like cybersecurity incidents are inevitable. It’s not a question of *if*, but *when*. The key to effectively navigating a security incident is a structured, well-tested response plan. At ImageNet, our Managed IT Security Team follows the proven framework outlined in NIST SP 800-61 (Computer Security Incident Handling Guide). Here’s how we approach it: **Step 1: Preparation** **Goal:** Be ready before an incident occurs. Strong preparation reduces both impact and response time. Key preparation activities include: - Developing and testing an Incident Response Plan (IRP) - Training employees on how to recognize and report suspicious activities - Deploying prevention, monitoring, and detection tools such as endpoint detection and response (EDR), intrusion detection and prevention tools, SOC (security operations center) monitoring, etc. - Establishing communication protocols - Ensuring backups are resilient and regularly tested Preparation is the foundation of all incident response. Without it, the following could be slower and less effective*.* **Step 2: Detection and Analysis** **Goal:** Identify and confirm potential incidents quickly. Both technical monitoring and user awareness can support detection efforts. Indicators of compromise (IOCs) may include: - Unusual network traffic or unauthorized access attempts/account lockouts - Unexpected system behavior, such as slowness, popups, or other abnormal activity - Signs of data exfiltration or encrypted files - Alerts from security tools or third-party monitoring teams Once suspicious activity is detected, gather evidence, confirm whether it constitutes an incident, and assess its severity and scope. Respond with urgency, but take care not to be reckless. Careless mistakes or jumping to conclusions can cause other unnecessary disruptions. **Step 3: Containment, Eradication, and Recovery** **Goal:** Limit damage, remove the threat, and restore normal operations. This phase includes three critical steps: **Containment** – Stop the spread of the attack - Isolate affected systems or segment contaminated networks; do not shut down or power off systems, as this could destroy forensic evidence. - Disable compromised accounts or services. - Block malicious IP addresses & domains. - **If applicable, notify your insurance carrier**. Most carriers are willing to contain an incident, but they may require you to utilize their own incident response teams or meet specific forensic evidence requirements. Failure to adhere to their requirements could result in a reduced payout (or none at all). **Eradication** – Eliminate the root cause - Identify the attack vector (VPN compromise, unauthorized remote access tools, weak firewall rules, etc.) - Remove malware, unauthorized accounts, or other persistent footholds - Patch exploited vulnerabilities - Reimage compromised systems if necessary **Recovery** – Safely restore operations - Restore from clean, validated backups - Monitor systems closely for signs of reinfection - Gradually reintroduce affected systems and services - Communicate with stakeholders throughout the process Note that containment, eradication, and recovery aren’t always one-and-done. New evidence may reveal additional, previously unseen threats. The goal of this phase is thoroughness, not speed. **Step 4: Post-Incident Activity** **Goal:** Learn from the incident to strengthen our preparations and refine our response process. Post-incident activities should include: - Finalizing documentation of the timeline of events and remediation actions - Conducting a root cause and lessons-learned review with relevant stakeholder teams (security, IT, legal, leadership, etc.) - Updating incident response processes and procedures - Deploying new security tools or enhancing existing configurations - Fulfilling reporting and disclosure obligations (impacted clients, regulatory bodies, insurance, etc.) A thorough post-incident review brings opportunities for organizational growth and a more resilient security posture. ***Key Takeaway:** Incident response is not just about reacting in the moment, but rather about preparing in advance, acting decisively (but not recklessly) during an incident, and improving from lessons learned. Following the **NIST 800-61 framework** ensures a repeatable, effective process that can bring calm to the chaos that is a cybersecurity incident.* **Are you confident in your organization’s security posture? ImageNet’s Managed IT Services implement layered and comprehensive cybersecurity solutions to protect your business from emerging threats:** **Managed Advanced Endpoint Prevention**: Our endpoint security controls leverage AI and machine learning to prevent up to 99% of unknown threats with reaction times measured in **milliseconds**, monitored 24x7 by a US-based Security Operations Center (SOC). **DNS Security and Content Filtering**: Defend against web-based threats such as phishing websites, botnets, and cryptomining. Prevent employees from accessing inappropriate or time-wasting sites, whether they work in the office or remotely. **Security Awareness Training:** An interactive awareness training platform that delivers annual cybersecurity training, weekly “micro trainings” to keep users engaged, phishing simulations, and automated dark web scanning for your business email addresses. **Managed Email & Cloud Security:** Leverage AI to analyze emails for context, sender/receiver relationship strength, and other indicators of compromise to cut through spam, analyze attachments and links before delivery, identify phishing, and prevent account takeover (ATO) attempts. Ensure cloud-based collaborative files are scanned for malware. Secure communications with mail encryption and prevent insider threats with data loss prevention (DLP) controls. **Vulnerability Scanning:** Regularly identify vulnerabilities that put your systems at risk. Contextual reporting identifies the severity and likelihood of exploitation, allowing for prioritization of remediation efforts. **Privileged Access Management:** Stop worrying about whether removing employee admin rights will hinder productivity. Our solution ensures your users can run the applications and services with the permissions they need without leaving your systems vulnerable to excessive (and often unneeded) administrative rights. **Password Management:** Secure password management solutions eliminate the need for employees to choose between reusing weak passwords across multiple accounts or writing down multiple complex passwords. **Cyber Insurance Assessment:** Let our trusted partner evaluate your current policy to ensure you are adequately covered in the event of a cybersecurity incident.
