# --- Hardening -------------------------------------------------------------
|
|
# Unlike audit-endpoint.service, this one genuinely needs to write to the
|
|
# checkout (git reset --hard, npm install), hence ReadWritePaths below -
|
|
# everything else stays as locked down as the main service.
|
|
#
|
|
# NoNewPrivileges is deliberately NOT set here, unlike audit-endpoint.service:
|
|
# it flips the kernel's PR_SET_NO_NEW_PRIVS flag, which makes setuid bits
|
|
# (including /usr/bin/sudo's) inert for this process and everything it execs.
|
|
# deploy.sh's whole reason for running as this user is to call
|
|
# `sudo systemctl restart audit-endpoint` - a privilege escalation that is
|
|
# exactly what that flag exists to prevent. The two are fundamentally
|
|
# incompatible, not a configuration mistake to work around.
|
|
# The actual containment for that escalation is the narrow sudoers rule
|
|
# (audit-deploy-sudoers): exactly two "systemctl restart <unit>" commands,
|
|
# nothing else, regardless of this flag.
