Frequently asked questions
What is incident response and why is it critical for organizations?
Incident response is the structured process an organization follows to detect, contain, eradicate, and recover from cybersecurity incidents. It is critical because the speed and effectiveness of the response directly determines the business impact of an attack, including how much data is lost or stolen, how long systems are unavailable, and how significant the regulatory and reputational consequences are.
What are the main phases of an incident response process?
The standard incident response lifecycle consists of six phases: preparation (building the team, tools, and playbooks), identification (detecting that an incident has occurred), containment (limiting the spread and damage), eradication (removing the threat from the environment), recovery (restoring systems to normal operation), and lessons learned (reviewing what happened and improving future response).
What should an incident response plan include?
An incident response plan should define the incident response team members and their roles, the communication chain including executive and legal notification procedures, categorization criteria for classifying incident severity, technical playbooks for common attack types such as ransomware and phishing, contact lists for external resources such as forensic firms and legal counsel, and requirements for evidence preservation and regulatory reporting.
How frequently should organizations test their incident response capabilities?
Organizations should conduct tabletop exercises at least annually to walk through incident scenarios with all key stakeholders, and technical tests such as simulated phishing campaigns and red team exercises on a regular basis. After any significant real incident, a post-mortem exercise should be conducted to identify improvements. Regulatory frameworks such as DORA for financial institutions may impose specific testing frequency requirements.
