To control IP packet filtering, you would need a device called a firewall. A firewall is a network security device that monitors incoming and outgoing network traffic and decides whether to allow or block specific traffic based on defined security rules.

Firewalls play a crucial role in maintaining network security by acting as a barrier between a trusted internal network and untrusted external networks, such as the internet. They help prevent unauthorized access, data breaches, and other cyber threats.

How can you manage packet filtering in Linux?

What command is used to manage packet filtering in Linux?

Answer:

In Linux, the command used to manage packet filtering is iptables.

In Linux, the command used to manage packet filtering is iptables. It is a powerful command-line tool that allows you to set up rules for packet filtering and network address translation (NAT).

With iptables, you can create rules to allow or block specific types of traffic, define how packets should be forwarded, set up port forwarding, and more. It gives you granular control over network traffic, helping you enhance the security and performance of your Linux system.
