In some cases, it may be necessary to require password access to websites in certain categories.
For example, your company may block URL categories that threaten the safety and
wellbeing of employees. However, certain employees may need access to these
categories for research or other legitimate purposes. To balance safety and business
needs, implementing URL admin overrides can be an effective solution.
To create a URL admin override, set the action for a category to
override. Then, create a password that users must enter
to access sites in this category. When users attempt to access a website in a
category that you have overridden, a
Continue and Override response page
appears. This page notifies users that a website is blocked and prompts them to
enter a password to continue to the site.
Allow Password Access to Certain Sites (Strata Cloud Manager)
If you’re using Panorama to manage Prisma Access:
Toggle over to the PAN-OS & Panorama tab
and follow the guidance there.
If you’re using Strata Cloud Manager, continue here.
Go to the URL Access Management dashboard.
Select
Settings.
Create a URL admin override password.
Go to URL Admin Overrides, and
Add URL
Admin Overrides.
(
Optional) Select a
Mode for prompting
users for the password:
Transparent—The password
prompt appears to originate from the original destination URL. The
firewall intercepts the browser traffic destined for sites in a
URL category set to override and issues an HTTP 302 to prompt for
the password, which applies on a per-vsys level.
Redirect—The password prompt appears from
an Address (IP address or DNS hostname) that you
specify. The firewall intercepts HTTP or HTTPS traffic to a URL
category set to override and uses an HTTP 302 redirect to send the
request to a Layer 3 interface on the firewall.
Enter a
Password, then enter
it again to
Confirm Password.
(
Optional) Select an
SSL/TLS Service Profile.
You can create and manage SSL/TLS service profiles by clicking Create
New and Manage, respectively.
Save your changes.
(
Optional) Set the duration of override access
and password lockouts.
By default, users can access websites in categories for
which they have successfully entered an override password for 15
minutes. After the default or custom interval passes, users must
re-enter the password.
By default, users are blocked for 30
minutes after three failed password attempts. After the user is
locked out for the default or custom duration, they can try to access the
websites again.
Customize the General Settings.
For
URL Admin Override Timeout, enter
a value (in minutes) from 1 to 86,400.
For
URL Admin Lockout Timeout, enter
a value (in minutes) from 1 to 86,400.
Save your changes.
Specify the URL categories that require password access.
On the URL Access Management dashboard,
under the
Access Control tab, go to URL Access
Management Profiles and modify or

(
Redirect mode only) Create a Layer 3 interface
to which to redirect web requests to sites in a category configured
for override.
Create a management profile to enable the
interface to display the URL Filtering Continue and Override Page
response page:
Select and click Add.
Enter a Name for the profile, select Response
Pages, and then click OK.
Create the Layer 3 interface. Be sure to attach the
management profile you just created (on the tab of the Ethernet
Interface dialog).
(
Redirect mode only) To transparently redirect
users without displaying certificate errors, install a certificate
that matches the IP address of the interface to which you are redirecting
web requests to a site in a URL category configured for override.You
can either generate a self-signed certificate or import a certificate
that is signed by an external CA.
To use a self-signed certificate, you must first create
a root CA certificate and then use that CA to sign the certificate
you will use for URL admin override as follows:
To create a root CA certificate, select and
then click
Generate. Enter a
Certificate Name,
such as RootCA. Do not select a value in the
Signed By field
(this is what indicates that it is self-signed). Make sure you select
the
Certificate Authority check box and then
click
Generate the certificate.
To create the certificate to use for URL admin override,
click
Generate. Enter a
Certificate Name and
enter the DNS hostname or IP address of the interface as the
Common
Name. In the
Signed By field,
select the CA you created in the previous step. Add an IP address
attribute and specify the IP address of the Layer 3 interface
to which you will be redirecting web requests to URL categories
that have the override action.
Generate the certificate.
To configure clients to trust the certificate, select
the CA certificate on the
Device Certificates tab
and click
Export. You must then import the
certificate as a trusted root CA into all client browsers, either
by manually configuring the browser or by adding the certificate
to the trusted roots in an Active Directory Group Policy Object
(GPO).
Specify which URL categories require an override password
to enable access.
Select and either select
an existing URL Filtering profile or
Add a
new one.
On the
Categories tab, set
the Action to
override for each category
that requires a password.
Complete any remaining sections on the URL Filtering
profile and then click
OK to save the profile.
Apply the URL Filtering profile to the Security policy
rule(s) that allows access to the sites requiring password override
for access.
Select and select the appropriate
Security policy to modify it.
Select the
Actions tab and
in the
Profile Setting section, click the
drop-down for
URL Filtering and select the
profile.
Click
OK to save.
Commit the configuration.
