Package sshguard

Protects hosts from brute-force attacks against SSH and other services


Sshguard protects hosts from brute-force attacks against SSH and other
services. It aggregates system logs and blocks repeat offenders using one of
several firewall backends.

Sshguard can read log messages from standard input or monitor one or more log
files. Log messages are parsed, line-by-line, for recognized patterns. If an
attack, such as several login failures within a few seconds, is detected, the
offending IP is blocked. Offenders are unblocked after a set interval, but can
be semi-permanently banned using the blacklist option.

Version: 2.4.3
