Answers Explanation & Hints: nftables is a rule-based access control and logging system for Linux, which is used to configure network access rules that are part of the Linux kernel Netfilter modules. It provides the ability to filter and manipulate network traffic by creating and manipulating rules and filtering criteria. Unlike iptables, nftables uses a simpler syntax and provides more functionality, such as supporting IPv6 natively, being able to use sets, maps, and expressions, and providing better logging and monitoring capabilities. Therefore, nftables is a popular choice for Linux system administrators to configure host-based firewalls. |
