**Course Title:** Security Best Practices in Software Development **Section Title:** Incident Response and Management **Topic:** Develop an incident response plan for a hypothetical security breach. **Overview:** In this lab topic, you will develop an incident response plan for a hypothetical security breach. This plan will help you respond effectively to a security incident and minimize the impact on your organization. You will learn about the key components of an incident response plan, how to identify and contain a security breach, and how to eradicate and recover from the breach. **Objective:** Upon completing this topic, you will be able to: * Develop an incident response plan for a hypothetical security breach * Identify and contain a security breach * Eradicate and recover from a security breach * Understand the key components of an incident response plan **Materials Needed:** * Computer with internet access * Notepad and pen for note-taking * Incident Response Plan Template (optional) **Prerequisites:** Before starting this topic, you should have a basic understanding of security concepts and terminology, incident response planning, and security best practices. **Step 1: Define the Incident Response Plan Scope and Purpose** The first step in developing an incident response plan is to define the scope and purpose of the plan. This includes identifying the types of security incidents that the plan will address, the roles and responsibilities of the incident response team, and the goals of the plan. **Example:** Suppose you are the incident response manager for an e-commerce company. The company has experienced a security breach that resulted in the theft of customer credit card information. The scope of the incident response plan would include: * Identifying and containing the security breach * Notifying affected customers and stakeholders * Eradicating the root cause of the breach * Recovering from the breach and restoring normal operations * Reviewing and updating the incident response plan to prevent similar breaches in the future **Step 2: Identify the Incident Response Team** The next step is to identify the incident response team members and their roles and responsibilities. This includes: * Incident response manager * Security team members * IT team members * Communications team members * Stakeholders **Example:** Continuing with the e-commerce company example, the incident response team might include: * Incident response manager: John Doe * Security team members: Jane Smith, Bob Johnson * IT team members: Mike Davis, David Lee * Communications team members: Sarah Taylor, Emily Chen * Stakeholders: CEO, CIO, customers, shareholders **Step 3: Define the Incident Classification and Response** The next step is to define the incident classification and response. This includes: * Identifying the types of security incidents (e.g., unauthorized access, data breaches) * Classifying the incidents based on severity and impact (e.g., low, medium, high) * Defining the response to each type of incident **Example:** Continuing with the e-commerce company example, the incident classification and response might be: * Unauthorized access: Medium severity, respond within 24 hours * Data breach: High severity, respond within 1 hour * Denial of service: Low severity, respond within 72 hours **Step 4: Develop the Incident Response Plan** The next step is to develop the incident response plan. This includes: * Identifying and containing the security breach * Notifying affected customers and stakeholders * Eradicating the root cause of the breach * Recovering from the breach and restoring normal operations * Reviewing and updating the incident response plan to prevent similar breaches in the future **Example:** Continuing with the e-commerce company example, the incident response plan might include: * Identifying and containing the security breach: + Isolate the affected systems + Activate the incident response team + Notifying affected customers and stakeholders * Notifying affected customers and stakeholders: + Develop a notification plan + Execute the notification plan * Eradicating the root cause of the breach: + Conduct a post-incident analysis + Identify the root cause of the breach + Implement a fix to prevent similar breaches in the future * Recovering from the breach and restoring normal operations: + Develop a recovery plan + Execute the recovery plan * Reviewing and updating the incident response plan: + Conduct a post-incident review + Identify areas for improvement + Update the incident response plan **Step 5: Test and Review the Incident Response Plan** The final step is to test and review the incident response plan. This includes: * Conducting a tabletop exercise or simulation * Reviewing the plan with stakeholders * Updating the plan based on feedback and lessons learned **Example:** Continuing with the e-commerce company example, the incident response plan might be tested and reviewed through a tabletop exercise. The exercise would simulate a security breach and the incident response team would respond accordingly. The plan would be reviewed and updated based on the results of the exercise. **Conclusion:** In this lab topic, you developed an incident response plan for a hypothetical security breach. You learned about the key components of an incident response plan, how to identify and contain a security breach, and how to eradicate and recover from the breach. You also tested and reviewed the incident response plan through a tabletop exercise or simulation. **Additional Resources:** * National Institute of Standards and Technology (NIST) - [Guidelines for Incident Handling](https://csrc.nist.gov/publications/detail/sp/800-61/final) * SANS Institute - [Incident Response Process](https://www.sans.org/security-resources/posters/incident-response-process/50/download) * Cybersecurity and Infrastructure Security Agency (CISA) - [Incident Response Plan](https://us-cert.cisa.gov/government-users/incident-response-plan) **Leave a Comment/Ask for Help:** Please leave a comment or ask for help in the comment section below if you have any questions or need further clarification on any of the topics covered in this lab.
