What it is
Observability / management UIs: SNMP, Syslog, Prometheus, Grafana.
Why it is risky
Exposed SNMP communities and dashboards leak your infra map and credentials, and are abused for amplification DDoS.
What to do
Use SNMPv3·auth and keep monitoring ports/UIs on internal networks behind authentication.
