The Ubuntu MATE blog have announced that SSHGuard will be enabled by default when users enable SSH in Ubuntu MATE for Raspberry Pi.
Ubuntu MATE 16.04.2 has disabled SSH by default, but once SSH is enabled by users — it will also enable SSHGuard at the same time. This will help protect the resource-limited Raspberry Pi devices against scripted attacks on their SSH service.
Users may also soon see SSHGuard pop up in other Raspberry Pi focused Linux distributions based on Ubuntu Pi Flavours for Raspberry Pi as per their blog.
SSHGuard team is pleased to see a Linux distribution install SSHGuard by default, and thanks the Ubuntu MATE for Raspberry Pi team for trusting SSHGuard to protect their users.
