Today, CISA released the Eviction Strategies Tool to provide cyber defenders with critical support and assistance during the containment and eviction phases of incident response. This tool includes:

• Cyber Eviction Strategies Playbook Next Generation (Playbook-NG): A web-based application for next-generation operations.
• COUN7ER: A database of atomic post-compromise countermeasures users can execute based on adversary tactics, techniques, and procedures.

Together, Playbook-NG and COUN7ER create a systematic, tailored eviction plan that leverages distinct countermeasures to effectively contain and evict adversarial intrusions.

The Eviction Strategies Tool directly addresses a critical gap: the need for a clear understanding of the necessary actions to properly contain and evict adversaries from networks and devices.

CISA encourages cyber defenders to use the Eviction Strategies Tool available on the CISA Eviction Strategies Tool webpage or download it directly from GitHub at https://github.com/cisagov/playbook-ng.
