Firewalls are a key part of any network security architecture. OpenBSD and FreeBSD have long been known for their effectiveness as a network device and basic firewall. Now, with even more robust networking stacks and advanced capabilities like state synchronization and packet normalization, the BSDs are becoming enterprise-capable firewall platforms. With some forethought with respect to firewall placement and security policies, your BSD-based firewall will help keep intruders at the doorstep and away from your internal resources. |
