Security

Packet Filter and Firewall Examples

Here are some example scenarios of how to protect your AS/400 when connecting to an external untrusted network like the Internet. In general, the AS/400 has very good built in security...but layers of security can help as the rogue hacker must defeat each layer in turn before doing any real harm.

• The AS/400 as a Sacrificial Lamb.
• The AS/400 as a Bastion 'firewall'.
• The AS/400 with a Packet Filter.
• The AS/400 with a Bastion Host Firewall.
• The AS/400 with a Bastion Host Firewall and Packet Filter.

Note: More ways to secure a network can be found in any good network security book. The above are just a representative sampling.
