High Security Issues

[INTERNET-MON-001] Automatic NetworkManager stop/start on connectivity failure

install_internet_monitor.sh : 380-423

Monitor calls systemctl stop/start NetworkManager when ping fails.

Impact: Flapping connectivity causes repeated network restarts (DoS).

Medium Issues

[INTERNET-MON-002] play_audio passes basename-only path to Asterisk

install_internet_monitor.sh : 260-266

When audio exists only under SOUND_DIR, basename alone passed to rpt localplay.

Impact: Audio alerts may silently fail to play.
