Overview

Overview

Definition

URL filtering regulates online behavior by controlling which URLs users can access. For certain category of URL packets, the AP can change the DSCP value (DSCP priority) in the packets, so that other network devices can distinguish between packets based on the changed DSCP priorities and take a specified action on each type.

NOTE:
Currently, URL filtering can filter only HTTP URL requests.

Objective

With rapid development of Internet applications and the popularity of computer networks, the acquisition, sharing, and dissemination of information have become more widespread than ever, which brings unprecedented threats to enterprises.

  • Visiting non-work-related websites during working hours reduces work efficiency.
  • Visiting illegitimate or malicious websites may result in information leaks and threats such as worms, viruses, and Trojan horses.
  • When the intranet is congested, employees may be unable to access work-related websites, such as the company homepage and search engine, deteriorating work efficiency.

URL filtering allows you to manage users' online behavior on an individual basis, by user or user group, by schedule, and through the security zone. In addition, URL filtering technology allows you to change the DSCP priorities of different category of URL packets, so that other network devices can take differentiated actions on the URL traffic.
