====== Ubuntu - Fail2Ban - Override the default configuration settings ======

Edit the **/etc/fail2ban/jail.d/defaults-debian.conf** file, and add configuration changes into the **[DEFAULT]** section to override.

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

[sshd]
enabled = true
</file>

<WRAP important>
**WARNING:**  Do not change entries in the **[sshd]** section, as that would override settings specifically for the sshd service.

  * Of course, if there is a need to override settings for the sshd service as well, then go ahead with changes in the sshd section.
    * See [[Ubuntu:Fail2Ban:Override the default configuration settings for the sshd service|Override the default configuration settings for the sshd service]].
