CISA's Open-Source Tool for Cyber Incident Eviction Strategies

CISA's New Eviction Strategy Tool

• 💡 CISA has released an open-source tool designed to address a gap in the incident response lifecycle, focusing on effective adversary eviction after an impact.
• 🎯 The tool aims to simplify the process of eradicating adversaries from an environment, moving beyond basic credential resets or system reformatting.
• 🔑 Challenges for incident responders include understanding the full extent of an attacker's actions, covering their tracks, and scoping the intrusion completely before remediation.

Building an Effective Eviction Plan

• 🛠️ The tool automates or simplifies the process of creating a customized eviction plan by breaking down technical steps into atomic tasks like changing passwords or reimaging machines.
• 🤝 It helps organize and convey necessary actions to various stakeholders, including system admins, network engineers, and SOC leadership, in the correct order.
• 🧩 The system integrates with the MITER ATT&CK framework and uses a database called COUNTER (counter with a 7) to identify countermeasures against adversary tactics, techniques, and procedures (TTPs).

Tool Accessibility and Use Cases

• 🌐 The tool is open-source to allow for examination in closed or classified environments and to encourage community development and adoption.
• 🏢 It is designed for any organization victimized by a cyber attack, from small to large, and is particularly useful for intrusions involving identity compromise.
• 📈 A key use case is for creating scenarios for tabletop exercises, helping organizations assess the time and resources needed for eviction before an actual emergency.

CISA's Mission and Future Development

• 🚀 The tool aligns with CISA's mission to support national cybersecurity by focusing on the critical but often overlooked containment and eradication phases of incident response.
• 🤝 CISA is adopting the tool internally and encourages the broader cybersecurity community to adopt, implement, and provide feedback for future improvements.
• ✨ The creators view this as a "gen one" capability, anticipating community contributions to evolve it into a more robust resource for critical infrastructure and other organizations.
