Web filtering is another important part of network security. Filtering is a software service that is designed to block access to phishing and malicious software websites. For example, imagine that one of your company’s employees receives a phishing email in his or her email inbox indicating that a package is waiting for him or her at the nearest pickup and delivery station. If that person was expecting a package at the same time, they might immediately click on the link without thinking about it. And as some of you will have experienced, the linked website will download malware and install it on his or her workstation. If your workplace uses web filtering, when someone clicks on the link, the browser will open instead and display a message saying that this site has been blocked by the administrator. This eliminates the need for downtime, virus removal, and data and network recovery.
