In this article, we'll explain how to install The Uncomplicated Firewall (ufw) on a Debian 10/11 server and use the 'Zenarmor' to enable next-generation firewall features like content and application filtering. The Debian server can also be configured as a firewalling and routing platform for networks, especially small business (SMB) and home networks, with the help of 'ufw'. To defend Debian servers from cyber threats, it is common to configure 'ufw' as a host-based firewall. ufw not only provides an easy-to-use interface for those unfamiliar with firewall concepts, but it also simplifies complex iptables instructions to assist an experienced system administrator. ![]() It is particularly useful for host-based firewalls. The Uncomplicated Firewall ( ufw) is an iptables frontend application that includes a framework for managing netfilter and a command-line interface (CLI) for interacting with the firewall. Because iptables firewall configuration for an average user is difficult, many iptables frontend applications have been developed. Learning iptables principles and becoming an iptables guru, on the other hand, maybe cumbersome. 'iptables' is a firewall solution that is highly configurable and adaptable. When a packet arrives at the server, it is routed to the Netfilter subsystem, which accepts, manipulates, or rejects it based on the rules provided by userspace through iptables. A total of 5 years of security support is available for each Debian release.įor access control, Debian includes a built-in L4 packet filtering system called Netfilter, as well as an interface called iptables for configuring the Netfilter. It will be supported for around three years, including updates for major security and usability issues. ![]() Debian releases a new stable branch every two years. Many other distributions, including Ubuntu, are based on Debian. It is developed by the community-supported Debian Project, which was founded by Ian Murdock in 1993.
