containing-active-breach
Executes containment strategies to stop active adversary operations and prevent lateral movement during a confirmed security breach. Implements short-term and long-term containment using network segmentation, endpoint isolation, credential revocation, and access control modifications. Activates for requests involving breach containment, lateral movement prevention, network isolation, active threat containment, or live incident response.

# Containing Active Breaches
## When to Use
- A confirmed intrusion is in progress with an active adversary on the network
- Malware is spreading laterally across endpoints or servers
- A compromised account is being used for unauthorized access to systems
- Ransomware encryption has been detected and is actively propagating
- An attacker has established command-and-control communications from internal hosts
**Do not use** for post-incident cleanup when the adversary is no longer active; use eradication procedures instead.
