Building a Simple Incident Response Plan for Automation

The Core Components of an IRP

Before you can automate your incident response, you need a well-defined plan. A basic incident response plan (IRP) should include the following steps:

1. Preparation: This involves identifying critical assets, developing security policies, and training employees on security best practices.
2. Identification: Detecting and identifying security incidents, such as malware infections, unauthorized access attempts, or data breaches.
3. Containment: Isolating affected systems to prevent the spread of the incident.
4. Eradication: Removing the threat from the affected systems.
5. Recovery: Restoring systems to normal operation and verifying their security.
6. Lessons Learned: Analyzing the incident to identify areas for improvement in security policies and procedures.

Tailoring Your IRP for Automation

To effectively automate your IRP, you need to define specific triggers and actions for each step. For example:

• Trigger: Detection of a suspicious login attempt from an unknown IP address.
• Action: Automatically block the IP address, notify the security team, and initiate a password reset for the affected user.

The key is to break down each step into discrete, repeatable actions that can be automated by a SOAR platform. When I tested Cortex XSOAR version 6.5, I found its visual playbook editor extremely helpful in mapping out these steps and defining the corresponding actions. The drag-and-drop interface allowed me to quickly create complex workflows without writing a single line of code.

Example IRP Scenario: Phishing Attack

Let's consider a simple phishing attack scenario:

1. Identification: An employee reports receiving a suspicious email.
2. Containment: The SOAR platform automatically quarantines the email and blocks the sender's address.
3. Eradication: The SOAR platform scans all other employee inboxes for similar emails and removes them.
4. Recovery: The SOAR platform provides training materials to employees on how to identify phishing emails.
5. Lessons Learned: The security team analyzes the phishing email to identify new indicators of compromise (IOCs) and update security policies.
