DenyHosts is a python program that automatically blocks SSH attacks by adding entries to /etc/hosts.deny. DenyHosts might also inform Linux administrators about offending hosts, attacked users and suspicious logins.
Example of use: check box-example
Simple:
- {
role: "sa-denyhosts"
}
Advanced:
my_whitelisted_boxes:
- "sshd: 192.168.0.10"
- "sshd: 192.168.0."
- "sshd: 192.168.0.0/255.255.255.0"
- {
role: "sa-denyhosts",
deploy_whitelisted_hosts: "{{my_whitelisted_boxes}}"
}
