Incident Response
When something goes wrong, speed and preparation determine the outcome. Effective response minimizes damage, protects reputation, and gets you back to business.
Why Response Preparation Matters
Every minute counts during a security incident. Organizations with prepared response plans contain breaches in hours. Those without can take weeks—during which damage multiplies, costs escalate, and trust erodes.
Effective incident response means:
- • Clear roles and decision-making authority
- • Documented procedures and playbooks
- • Rapid containment of threats
- • Evidence preservation for investigation
- • Coordinated communication (internal and external)
- • Risk management for AI system failures
You don't want to be writing your response plan while under attack. Preparation saves businesses.

- • Insurance claim filing
- • Public relations management
- • Documentation for compliance
Incident Mitigation
Stopping the bleeding and preventing further damage.

- • Configuration changes
- • Temporary workarounds
The Incident Response Lifecycle
Preparation
Develop plans, train teams, establish tools and communication channels before incidents occur.
Detection & Analysis
Identify the incident, assess severity, determine scope, and classify the threat.
Containment
Stop the incident from spreading. Isolate affected systems while maintaining business operations where possible.
Eradication
Remove the threat from the environment. Delete malware, close vulnerabilities, revoke compromised credentials.
Recovery (next phase)
Restore systems, validate security, return to normal operations, and monitor for re-compromise.
Lessons Learned
Post-incident review to improve detection, response, and prevention for the future.
Common Incident Scenarios
Ransomware Attack
Files encrypted, systems locked, ransom demand received.
Response priorities: Isolate infected systems, identify patient zero, assess backup viability, activate recovery plan, notify law enforcement.
Phishing / BEC
Employee clicked malicious link or credentials compromised.
Response priorities: Reset passwords, review account activity, check for email forwarding rules, assess data access, notify affected parties.
Data Breach
Unauthorized access to sensitive customer or business data.
Response priorities: Determine scope of exposure, preserve evidence, close access path, assess notification requirements, file regulatory reports.
Insider Threat
Employee or contractor acting maliciously or negligently.
Response priorities: Revoke access, preserve logs, conduct investigation, coordinate with HR/legal, assess data exfiltration.
DDoS Attack
Systems overwhelmed by traffic, services unavailable.
Response priorities: Activate DDoS mitigation, identify attack vectors, communicate with ISP, maintain customer communication, assess for secondary attacks.
AI System Failure
AI producing biased, inaccurate, or harmful outputs.
Response priorities: Suspend AI system, assess impact, identify root cause, notify stakeholders, implement human review, document for compliance.
Managing AI System Incidents
AI incidents differ from traditional security incidents. They may involve:
- • Biased or discriminatory outputs affecting customers
- • Inaccurate predictions leading to bad business decisions
- • Data leakage through AI prompts or responses
- • Model poisoning or adversarial attacks
- • Regulatory violations (privacy, fairness, transparency)
- • Reputational damage from AI failures
Response to AI incidents requires: immediate containment (system suspension), impact assessment, stakeholder notification, root cause analysis, and process improvements.
Know Your Notification Requirements
NYDFS 23 NYCRR 500
Financial services must notify DFS within 72 hours of cybersecurity events affecting normal operations or requiring regulatory notification.
HIPAA Breach Notification
Breaches affecting 500+ individuals require notification to HHS, media, and affected individuals within 60 days. Smaller breaches reported annually.
State Breach Notification Laws
New York requires notification "in the most expedient time possible" after discovery. Most states have similar requirements with varying timelines.
Cyber Insurance
Your policy likely requires immediate notification of incidents that may trigger a claim. Delay can void coverage.
