## Recommended Actions

Based on the risk profile, the following firewall rules are recommended:

```bash

# iptables

iptables -A INPUT -s 156.225.1.37 -j DROP

# nftables

nft add rule inet filter input ip saddr 156.225.1.37 drop

# pfSense

156.225.1.37/32

# Cloudflare WAF

{"description":"Block 156.225.1.37 — IPDebrief risk score 40","action":"block","filter":{"expression":"ip.src eq 156.225.1.37"}}

# AWS WAF

{"Addresses":["156.225.1.37/32"],"Description":"IPDebrief risk 40"}

```

These recommendations are probabilistic and should be combined with additional threat intelligence signals before implementing blocking rules.

## Intelligence Assessment

IP 156.225.1.37 presents moderate risk primarily due to geolocation inconsistencies and DNSBL listings. No active threat indicators or malicious behavior were observed.
