## SOC ACTIONABLE RECOMMENDATIONS

Immediate Actions

1. DNSBL Validation: Investigate the 2 high-severity blacklist listings to determine specific feed sources and rationale

2. Traffic Monitoring: Monitor for outbound connections; no inbound services detected

3. Baseline Establishment: Establish traffic baseline for future anomaly detection

Mitigation Rules

```

# Block if DNSBL reputation degrades further

ipaddr 51.222.13.193 tcp dpt:25 reject reason "Policy: Reputational concern"

ipaddr 51.222.13.193 tcp dpt:587 reject reason "Policy: Reputational concern"

# Allow if investigation confirms false positive

ipaddr 51.222.13.193 tcp dpt:443 accept

```

Investigation Priority: **MEDIUM**

• The moderate risk score warrants attention but does not indicate immediate threat
• DNSBL presence requires verification against specific blacklist policies
• Cloud infrastructure nature suggests potential for legitimate enterprise use
