Prisma Access

Use Test A Site to see how PAN-DB—the URL filtering cloud database—categorizes a specific URL and to learn about all possible URL categories.
You can also use Test A Site to submit a request to change the category for a URL if you disagree with how a specific URL is categorized.
Create a passive URL Access Management profile that alerts on all categories.
A log entry will be created for any website that exists in PAN-DB that is in a category set to any action other than
allow
.

.
Under URL Access Management Profiles, select the checkbox next to the best-practices profile and then
Clone
the profile.
The cloned profile appears under the profiles with the name

.
Select the
best-practices-1
profile and rename it. For example, rename it to
url-monitoring

Save
the profile.
Apply the URL Access Management profile to Security policy rules that allow traffic from clients in the trust zone to the Internet.
A URL Access Management profile is only active when it’s included in a profile group that a Security policy rule references.
Follow the steps to activate a URL Access Management profile (and any Security profile).
Make sure the
Source Zone
in the Security policy rules you add URL Access Management profiles to is set to a protected internal network.
Push Config
to commit the configuration.
View the URL logs to see which website categories your users are accessing. The categories you’ve set to block are also logged.

Next Steps:
For everything that you do not allow or block, use risk categories to write simple policy based on website safety. PAN-DB categorizes every URL with a risk-level (high, medium, and low). While high and medium-risk sites are not confirmed malicious, they are closely associated with malicious sites. For example, they might be on the same domain as malicious sites or maybe they hosted malicious content until only very recently.
You can take precautionary measures to limit your users’ interaction high-risk sites especially, as there might be some cases where you want to give your users access to sites that might also present safety concerns (for example, you might want to allow your developers to use developer blogs for research, yet blogs are a category known to commonly host malware).
Pair URL filtering with User-ID to control web access based on organization or department and to block corporate credential submissions to unsanctioned sites:
URL filtering prevents credential theft by detecting corporate credential submissions to sites based on the site category. Block users from submitting credentials to malicious and untrusted sites, warn users against entering corporate credentials on unknown sites or reusing corporate credentials on non-corporate sites, and explicitly allow users to submit credentials to corporate sites.
Add or update a Security policy rule with the passive URL Access Management profile so that it applies to a department user group, for example, Marketing or Engineering. Monitor the department activity, and get feedback from department members to understand the web resources that are essential to the work they do.
Consider all the ways of leveraging URL filtering to reduce your attack surface. For example, a school may use URL filtering to strict safe search settings for students. Or, if you have a security operations center, you might give only threat analysts password access to compromised or dangerous sites for research.
Follow URL filtering best practices.
