## Goal{% #goal %}

Detect the [SSH password guesser notice](https://docs.zeek.org/en/master/scripts/policy/protocols/ssh/detect-bruteforcing.zeek.html).

## Triage and response{% #triage-and-response %}

1. Identify the owners of the host that has been accessed.
1. Work with the team to understand if this authentication was expected/legitimate.
1. If it is determined that the activity is malicious:
   - Block the IP address, if it aligns with organization incident response processes.
   - Begin your organization's incident response process and investigate.
