Pros and cons of placing a Web server behind the firewall.
| ADVANTAGES | DISAVANTAGES |
| Fail-safe protection | Might not support all desired protocols (especially multimedia) |
| Reduces burden on O/S administrator to maintain optimum security configuration | Potential performance hit |
| Protects against mistakes in Web-server configuration (for example, accidentally leaving a dangerous network service running) | Increases risk to other systems on the Web server's LAN segment |
| Prevents server crashes from denial-of-service attacks | Additional cost |
| Convenient attack alert mechanism (paging, email, audio alarm) | Complicates management of remote access (approved users must be explicitly listed and authentication method configured) |
| Provides strong authentication method for remote access, accommodating remote updates to the server without increasing risk of attack |
