Explanation & Hint:

  1. iptables: This is a rule-based access control and logging system for Linux packet filtering based on IP addresses and network services. It is a legacy tool that has been widely used for configuring the Linux kernel’s netfilter framework.
  2. nftables: This is an application that allows Linux system administrators to configure network access rules that are part of the Linux kernel Netfilter modules. It is the successor to iptables and provides a new syntax for rule configuration.
  3. TCP Wrappers: This application uses a simple virtual machine in the Linux kernel where code is executed and network packets are inspected. However, the description might be a bit misleading as TCP Wrappers typically refers to a host-based networking ACL system, used to filter network access to Internet protocol servers on Unix-like operating systems. It does not use a virtual machine but instead is based on the libc wrappers.
