## 2.9. UFW Hardening
* **Description**: Defaults to `deny incoming` and (optionally) `deny outgoing`; automatically opens only whitelisted ports.
* **Primordial SSH exception**: `--primordial-ssh <port>` adds an outgoing-only UFW TCP exception for a bootstrap/recovery SSH
port when the live system's UFW outgoing policy is `deny`. It adds no incoming firewall rule and does not replace
`--ssh-port`. If the requested port already matches an existing outgoing SSH exception, the current hook still emits the
requested labelled rule because this repository has no separate UFW rule deduplication layer.
* **Rationale**: Implements a default-deny firewall, reducing lateral movement and data exfiltration risks immediately after
deployment.

Provides statistic only after successful building a CISS.debian.live-ISO. While enabling '--log-statistics-only'
the argument '--build-directory' MUST be provided.
--primordial-ssh <INTEGER>
Adds one outgoing UFW TCP exception for a bootstrap/recovery SSH port.
Outgoing only: no incoming firewall rule is added, and this option does not replace '--ssh-port'.
Effective only when the Live System's UFW outgoing policy is 'deny'.
Port MUST be a decimal integer between '1' and '65535'.
Example fragment:
./ciss_live_builder.sh --ssh-port 42842 --primordial-ssh 2222
--provider-netcup-ipv6
Activates IPv6 support for Netcup Root Server. One unique IPv6 address MUST be provided in this case and MUST be
encapsulated with [], e.g., [1234::abcd].
