New service, native on the host (not Docker) so it can call cscli and
read Asterisk's security log directly without bridging the
container/host boundary or exposing CrowdSec LAPI credentials to a
containerized frontend.
- Security Log tab: parses ~/docker/asterisk-digital-ocean/logs/full
for SIP auth failures (wrong password, unknown extension, etc.) with
timestamp/account/remote IP, classified by severity.
- CrowdSec tab: current bans via cscli, a delete/unban button per
entry, and ASN-exempt management for the Asterisk brute-force
scenarios (services/crowdsec.sh) without SSHing in.
- Link out to the existing Asterisk web admin (reads its domain from
asterisk-digital-ocean's own .env, doesn't hardcode or embed it).
Runs as a dedicated unprivileged system user (secdash), with sudo
scoped to exactly three commands via /etc/sudoers.d/security-dashboard
(cscli decisions delete --id <digits>, cscli decisions list -o json,
systemctl restart crowdsec) — validated with visudo -c. Listens on
127.0.0.1 only, reachable through Caddy, and refuses to proceed without
explicit confirmation if no Authelia (local or remote) is configured,
since this page can delete active security bans.
Stdlib-only Python (no framework), matching the RAM-conscious pattern
already used for Easy Asterisk's own web admin. All embedded code
(bash, Python, JS) syntax-checked; the generated sudoers rule
validated with visudo -c -f.
