The AS/400 Takes You Securely Where You Want to Go


This article on the built-in security features of the AS/400 system originally appeared in the Midrange Computing’s Showcase Magazine, June 2000.

nat firewall  bits 5769-CE3 IP-Masquerading through NAT For added security, the AS/400 is able to perform IP-masquerading through Network Address Translation (NAT). NAT hides the real IP address of outbound packets, assigning them a single public IP address. This type of IP proxying secures the internal network by not broadcasting the real IP addresses making an AS/400 network less vulnerable to IP spoofing and being used a launch point for Denial of Service attacks.

IPSec VPNs for Extranets: Not what you want to wake up next to
