Chapter 12, Problem 7RQ
Explanation of Solution
Differences between screened-host firewall architecture and screened-subnet firewall architecture:
| Screened-host firewall architecture | Screened-subnet firewall architecture |
| It allows single host and defender host of defense against possible attack. | It is similar to screened-host firewall architecture, except that it has multiple defender hosts and lies behind a packet filtering router... |
