What is Incident Response?

Q: How does IR integrate with cyber insurance?

Your carrier usually requires immediate notification (often within 24 hours), specifies approved response vendors, and dictates communication channels. Review your policy before an incident, not during.

Incident Response (IR) is the structured process for detecting, containing, eradicating, and recovering from cybersecurity incidents. A mature IR capability includes documented playbooks, defined roles, tested communication plans, and relationships with external specialists for incidents beyond internal capacity.

How It Works

How Incident Response works

Three-step view of how it operates in practice.

Prepare

Before an incident: playbooks, on-call rosters, vendor contracts, communication templates, table-top exercises.

Detect & contain

When something happens: investigate the alert, scope the compromise, isolate affected systems, stop the bleed.

Eradicate & recover

Remove the attacker’s persistence, restore from clean backups, harden against repeat, and document lessons learned.

Preparation

Policies, playbooks, tools, and tabletop exercises.

Most common

Detection & Analysis

Time-based one-time codes from an app like Microsoft Authenticator or Google Authenticator. Offline-capable and phishing-resistant against many attacks.

Convenient

Containment, Eradication, Recovery

The user approves a sign-in with a tap on their phone. Easy to use but vulnerable to MFA fatigue attacks — always pair with number matching.

Strongest

Post-Incident Activity

FIDO2 keys like YubiKey, or device-bound passkeys. Phishing-resistant by design — the key will not authenticate against a fake domain.

Pitfalls

Common Incident Response mistakes

No documented playbookFiguring it out live costs hours. Pre-decided first actions and escalation paths save days.
Untested planAdmins, finance, and anyone with access to money or sensitive data should use an app or hardware key — never SMS alone.
No legal & comms leadIR is more than technical. Insurance, notification deadlines, customer comms, and regulators all matter — pre-identified leads prevent chaos.
Single point of failureIf only one person knows how to do recovery, an incident plus that person’s absence becomes a catastrophe.

Common Questions

Incident Response frequently asked questions

Do we need an IR plan if we have cyber insurance?⌄

Yes — most insurers require a documented plan before issuing coverage, and will reject claims if response steps weren’t followed. The insurance carrier often has preferred IR vendors, which should be pre-identified.

What’s the first hour of incident response?⌄

Validate the alert is a real incident, isolate affected systems, preserve evidence (don’t reboot or wipe), notify the IR lead, and start an incident log. The log is your best friend in post-incident review and legal defense.

How often should we test our IR plan?⌄

Tabletop exercises annually at minimum, quarterly for high-risk sectors. Technical drills (actually running a simulated ransomware recovery) should happen quarterly.

Should we notify customers immediately?⌄

Depends on jurisdiction, contracts, and nature of incident. Most regulations allow 72 hours from confirmed breach to notification. Legal counsel should drive this, not IT alone.

How does IR integrate with cyber insurance?⌄

Have a documented recovery process before it happens. Typically an administrator verifies the user's identity through an out-of-band channel, temporarily disables MFA, and re-enrolls the user with a new device. Backup codes or a secondary security key reduce downtime.
