## RECOMMENDED ACTIONS

Based on IPDebrief analysis, implement the following controls:

Firewall Rules:

• `iptables -A INPUT -s 93.137.40.16 -j DROP`
• `nft add rule inet filter input ip saddr 93.137.40.16 drop`

WAF/Proxies:

• Block at Cloudflare/AWS WAF with expression: `ip.src eq 93.137.40.16`
• Risk score 40 warrants defensive blocking for high-security environments

Assessment: While no active threats are present, the moderate risk score combined with DNSBL listings suggests precautionary blocking for sensitive workloads.
