This cybersecurity playbook is inspired by Amy Chaney's experience with a significant cybersecurity event that shook the industry not long ago: the infamous Log4Shell vulnerability.
She recently spoke to the CyberOxTales podcast, sharing first-hand her experiences on the front lines at JPMorgan Chase during the crisis.
From understanding the complexities of vulnerability to managing global teams tasked with rapid response, Amy discusses the importance of preparedness, modernization, and teamwork.
Playbooks
objective:
The main goals are:
- Establish a comprehensive and accurate inventory system for all your software assets so you can quickly identify and mitigate vulnerabilities.
- Develop clear, well-practiced incident response plans, including war rooms and tabletop exercises, to ensure a coordinated and effective approach to dealing with cyber incidents.
- Implement system-wide upgrade and patch automation to minimize human error and ensure timely updates are applied.
- Ensure a modern, agile, and robust system architecture that is tolerant of single points of failure and can adapt to new threats.
- Adopt a strategic communications protocol that clearly defines roles, responsibilities and action steps, balancing both descriptive and prescriptive guidance to ensure precise responses during the event.
- Foster a culture of continuous improvement and learning that prioritizes security in all aspects of technology development and operations.
Step 1: Ensure comprehensive inventory management
objective: Ensure that an accurate and up-to-date inventory of all assets is maintained, including hardware, software, data, and dependencies.
Action items:
- Scan all assets regularly
- Classify assets according to their importance and business impact
- Maintain a configuration management database (CMDB) that contains all the relevant details for each asset
- Incorporate third-party and vendor asset information into the CMDB
Step 2: Conduct an incident response tabletop exercise
objective: Validate the effectiveness of your incident response plans and improve your team's readiness through simulated events.
Action items:
- Schedule and conduct regular tabletop exercises involving all relevant parties
- Develop scenarios that include, but are not limited to, common and emerging threats
- Review and revise your incident response plan based on lessons learned during the exercise
- Ensuring smooth collaboration between internal teams and external partners
Step 3: Create a verification and validation process
objective: Develop process flows for validating the effectiveness of defenses and implementation of security controls.
Action items:
- Automate security configuration validation checks
- Regularly test your backup and recovery processes
- Conduct penetration tests and vulnerability assessments
- Leveraging threat intelligence to inform the validation process
Step 4: Review your security-centric architecture design
objective: Integrate security considerations into your architecture design process to prevent single points of failure and increase resiliency.
Action items:
- Involve your security team in the early design stages of any project
- Promote modular and microservices architectures to reduce footprint
- Implement redundancy and failover mechanisms
- Follow the principle of least privilege in system design
Step 5: Understand descriptive and prescriptive communication
objective: Adapt your communication style to the appropriate context: strategic planning (descriptive) vs. active incident response (prescriptive).
Action items:
- The planning stage details how the system should be built or designed for security.
- During an active incident, issue clear, concise instructions detailing who needs to take action, where, and how.
Step 6: Focus on process modernization and automation
objective: Ensure your organization’s technology stack is up to date and security processes are automated, reducing manual errors and fatigue.
Action items:
- Create a legacy system modernization roadmap
- Implement an automated patch management and update process
- Leverage data-driven decision-making models to inform security operations
- Deploy tools for continuous monitoring and real-time alerts
Step 7: Data-driven reporting accuracy
objective: It provides a high level of accuracy and clarity in security data reporting, facilitating fast and informed decision-making.
Action items:
- Integrate with your security information and event management (SIEM) system for centralized logging and alerting.
- Establish clear lines of communication for data-driven insights
- Employing advanced analytics for incident forensics and prediction
Step 8: Prepare and develop your playbooks in advance
objective: Develop and maintain security playbooks for immediate action in the face of threats, prioritizing speed and agility of response.
Action items:
- Document incident response protocols and checklists
- Predefined roles and responsibilities within the incident response team
- Allows for rapid mobilization of resources to respond to incidents
- Perform regular review and updates of playbooks
