Firewall Rules (iptables):

```

# Allow established connections

iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT

# Allow HTTPS (port 443) - required for web services

iptables -A INPUT -p tcp --dport 443 -j ACCEPT

# Allow HTTP (port 80) - required for web services

iptables -A INPUT -p tcp --dport 80 -j ACCEPT

# Allow SSH (port 22) with rate limiting

iptables -A INPUT -p tcp --dport 22 -m limit --limit 3/min -j ACCEPT

# Log and drop all other traffic

iptables -A INPUT -j LOG --log-prefix "IPDEBRIEF_DROP: "

iptables -A INPUT -j DROP

```
