Effective Incident Response: A Cybersecurity Guide for Executives

This cybersecurity guide is inspired by David Cross’s insights on how to best handle a potential incident caused by a seemingly suspicious email sent to a marketing team.

He recently shared his recommendations on the CyberOXtales podcast, emphasizing the importance of having a clear incident response script, setting the threshold for management involvement, and conducting a post-mortem analysis after each activity.

Objective:

The goal of this playbook is to provide a clear and effective process for dealing with potential cybersecurity incidents within an organization. It aims to ensure a timely and consistent response to security threats, minimize impact, and facilitate post-event analysis for continuous improvement.

The main objectives include:

Respond quickly and effectively to potential cybersecurity incidents.
Clear communication and escalation process for incident reporting and management involvement.
Establish a consistent postmortem analysis and root cause analysis (RCA) process for learning and improvement.

Step 1: Identify and report the incident

Objective: The goal is to create a standardized and documented process for identifying, reporting and responding to potential security threats to ensure consistency and efficiency in incident handling.

Action items:

Promote training of your employees to recognize potential cybersecurity threats.
Implement a central reporting system for security incidents.

Step 2: First assessment

Objective: To systematically assess and review potential data leaks or security incidents so that proactive and thorough responses can be made and risks to the company’s data and systems can be mitigated.

Action items:

Level 1 support, incident responders or designated responders to assess the potential incident.
Determine the threshold for management involvement based on predefined criteria.

Step 3: Dealing with potential data breaches

Objective: To ensure rapid and informed support in assessing and responding to potential incidents, appropriate expertise and leadership must be involved so that the impact of potential threats on the organization is minimized.

Action items:

Use predefined protocols to evaluate potential data breaches.
Immediate involvement of key personnel, particularly the CISO, when a high level of certainty or probability of impact of a real event is identified.

Step 4: Communication and escalation

Objective: Providing management with timely and accurate information about potential threats when there is a high level of confidence or probability that an actual event will occur, to enable informed decision-making and resource allocation.

Action items:

Use defined templates for consistent communication with management regarding potential incidents.
Make sure the right levels are informed based on the playbook and owners to avoid misunderstandings.

Step 5: Postmortem and Root Cause Analysis (RCA)

Objective: Collect lessons learned and identify opportunities to learn and improve from addressing potential threats, foster a culture of continuous improvement and preparedness for future incidents; capture and institutionalize lessons learned from incident response, prepare the organization for future incidents, and foster a culture of preparedness and continuous learning.

Action items:

After the event, debrief and analyze to learn and improve.
Use a neutral facilitator to separate learning from blame and create an unbiased atmosphere.
Based on the lessons learned, develop playbooks and templates for future incidents.
