====== Ubuntu - Fail2Ban - Override the default configuration settings for the sshd service ======

sshd is the only service monitored by fail2ban by default.

Edit that **/etc/fail2ban/jail.d/defaults-debian.conf** file, and add configuration changes into the section of the sshd service.

<file bash /etc/fail2ban/jail.d/defaults-debian.conf>
[DEFAULT]
banaction = nftables
banaction_allports = nftables[type=allports]
backend = systemd

[sshd]
enabled = true

# The following lines override the default values for the sshd service
bantime = 600
findtime = 3m
maxretry = 5
action = %(action_mw)s
</file>

<WRAP info>
**NOTE:**  Various entries have been added into the **[sshd]** section to override the default values.
</WRAP>
