A law office uses a Linux host as the firewall device for the network. The IT administrator is configuring the firewall iptables to block pings from Internet devices to the Linux host. Which iptables chain should be modified to achieve the task?
- INTERNET
- INPUT
- OUTPUT
- FORWARD
Explanation: The firewall iptables uses the concepts of chains and rules to filter traffic:
INPUT chain – handles traffic entering the firewall and destined to the firewall device itself
OUTPUT chain – handles traffic originating within the firewall device itself and destined to somewhere else
FORWARD chain – handles traffic originated somewhere else and passing through the firewall device
