# deploy-ansipa-policies.yml — deploy the policy enforcement daemon to enrolled clients.
|
||
#
|
||
# Installs ansipa-enforce-policies.sh and a systemd timer that runs it every 30 minutes.
|
||
# Device policies (FreeIPA host groups — applied to the whole machine):
|
||
# dev_daemon-enable-<unit> Ensure <unit> is enabled and running; reverted when host leaves group
|
||
# dev_daemon-disable-<unit> Ensure <unit> is disabled and stopped; reverted when host leaves group
|
||
# dev_timeshift-backup Enforce daily Timeshift snapshots (03:00)
|
||
# dev_security-scan Enforce daily ClamAV + rkhunter + chkrootkit scans + SMB upload (02:00)
|
||
# dev_no-local-users Lock local account passwords; only FreeIPA accounts can auth
|
||
# dev_local-sudo-<username> Grant <username> local sudo on this device; reverted when host leaves
|
||
# dev_ssh_<userid> Distribute <userid>'s SSH public keys from IPA to authorized_keys
|
||
# on this device; allows that IPA user to SSH in from any of their
|
||
# registered keys without a password. Keys stored in IPA via:
|
||
# ipa user-mod <userid> --sshpubkey='ssh-ed25519 AAAA...'
|
||
#
|
||
# User policies (FreeIPA user groups — follow the user across all enrolled devices):
|
||
# usr_admin Grant full sudo on every enrolled host (sudoers drop-in, SSSD-resolved)
|
||
# usr_block-binary-<name> Block execution of <name> via a PATH-priority wrapper
|
||
# usr_prt_<printer> Auto-add printer at login (per-user); URI in IPA group description
|
||
# usr_scan-notify Fetch alerts from server, notify user every 10 min until acknowledged
|
||
# usr_smb_r_<name> Mount read-only Samba share ~/‹name› for members; credentials in IPA group description
|
||
# usr_smb_rw_<name> Mount read-write Samba share ~/‹name› for members (rw beats r if both)
|
||
#
|
||
# CheckMK monitoring policies (device host-groups, unless noted):
|
||
# dev_mon_base Install CheckMK agent; register host in CMK; check: installed packages.
|
||
# Credentials auto-discovered from IPA dev_mon_base description (set by
|
||
# ansipa-checkmk-setup.sh on the FreeIPA container).
|
||
# CPU/RAM/disk/uptime reported by built-in agent sections.
|
||
# dev_mon_malware Local check reporting ClamAV scan results from dev_security-scan log.
|
||
# Complement — does not replace dev_security-scan; both can coexist.
|
||
# dev_mon_timeshift Local check for most recent Timeshift snapshot age.
|
||
# WARN if >5 days, CRIT if >10 days, CRIT if no snapshots found.
|
||
# dev_mon_power Local check for CPU package TDP/power via Intel RAPL or lm-sensors.
|
||
# usr_mon_logins (User group) Local check for SSH login attempts in last 24h.
|
||
# Reports: successful + failed + invalid-user counts with thresholds.
|
||
#
|
||
# Prerequisites:
|
||
# - Host enrolled in FreeIPA (sssd + ipa CLI available)
|
||
# - For dev_security-scan / usr_scan-notify: samba-client installed (handled below)
|
||
# - For dev_security-scan / usr_scan-notify: smb_scan_password set (use ansible-vault in production)
|
||
# - For security-scan tools: also add host to dev_mod_anti-malware group
|
||
# - For timeshift-backup: also add host to dev_mod_timeshift group
|
||
#
|
||
# Usage:
|
||
# ansible-playbook -i inventory deploy-ansipa-policies.yml \
|
||
# -e smb_scan_password=<password> # or use --vault-password-file
