Tag: Firewall Rule

UFW is the acronym for the Uncomplicated Firewall application used to administer your firewall rules on Ubuntu, Debian, and Arch Linux. As you proactively manage your firewall to avoid cyberattacks, blocking internet protocol (IP) addresses or whitelisting only those IPs allowed are two different firewall management approaches that can assist you. Regardless of the approach, all system administrators want to manage the incoming network traffic and firewall security to stop bad actors with harmful intentions.

Many companies have replaced their live office meetings with video conferencing. It is the easiest way to get all employees together, present the latest news and updates, and effectively gather employee feedback. Whether it is for your office or your home network, properly configuring a firewall benefits video conferencing.

Introduction

Just as regular visitors reach our server every day, so do others with more nefarious intentions. It is simply not reasonable to run an online service without some layer of protection. To protect against some of these attacks, Ubuntu ships with ufw (Uncomplicated Firewall). This is a tool designed to make Ubuntu firewall management as easy and user-friendly as possible. Specifically, ufw provides a cleaner interface for the core firewall tools netfilter and iptables, which, while robust, can be challenging to master.
