10.11.5  P2P Download Security
When you download using P2P, you reveal your IP address. This increases the risk of hacking 
attacks, which can be protected against by a good firewall. 
Use a Hardware-based Firewall
Place a hardware-based firewall between your network and the Internet (a software-based firewall 
on your computer would just protect the computer itself, not the NSA since your computer is not 
between your NSA and the Internet). 
Figure 125   Firewall
Ideally your firewall should have the following:
• Stateful packet inspection to control access between the Internet and your network and protect 
your NSA (and computers) from hacking attacks.
• IDP (Intrusion Detection and Prevention) to detect malicious packets within normal network 
traffic and take immediate action against them.
