Now, let's configure URL filtering on your firewall.How to configure URL filtering rules.Configure a Passive URL Filtering policy to simply monitor traffic.The recommended practice for deploying URL filtering in your organization is to first start with a passive URL filtering profile that will alert on most categories. Click OK.Apply the URL filtering profile to the security policy rule(s) that allows web traffic for users. Most changes will not affect the running environment such as updating automation infrastructure, The first place to look when the firewall is suspected is in the logs. Can you identify based on couters what caused packet drops? Such systems can also identifying unknown malicious traffic inline with few false positives.
