You can create, manage, and reorder Internet Access rules in the security rulebase.
Each Internet Access rule generates multiple security rules when implemented. The
rules inherit from folders and can also come from snippets. They reference objects
and configurations in their scope. This method integrates internet access control
with the existing security rule management.
Create a Security Policy Rule (Strata Cloud Manager)
Learn how to create a security rule.
To ensure that end users authenticate when they try to access your network
resources, authentication is evaluated before Security policy. For details, see
Authentication.
Add a rule.
Select and build your rule by configuring the following
rule
components.
Components marked with an asterisk(*) are mandatory.
In the
General tab, enter a descriptive
Name for the rule.
Give a
Description for your rule's intent.
Add
Tag to your rules to group them using keywords or
phrases.
Limit a security rule to specific times using a
Schedule.
Define the matching criteria for the source fields in the packet.
In the
Source tab, select a
Source
Zone.
Specify a
Source IP Address or leave the value
set to
ny.
You can search for specific
Usersor
User Groups to enforce policy for individual
users or a group of users. Specify the match criteria that define which
users and user groups.
- Sub string or partial string search is not supported for
performance reasons.
- Entire string search is possible when delimiters such as space
and hyphen is present.
- When number of users is more than 500 then string search use
quotes with exact string
If you're using GlobalProtect™ with host information profile (HIP)
enabled, you can also base the policy on information collected by
GlobalProtect. For example, the user access level can be determined from
the HIP that informs your environment about the user's local
configuration. The HIP information can be used for granular access
control based on the security programs that are running on the host,
registry values, and many other checks such as whether the host has
antivirus software installed.
If you decide to
Negate a
region as a source address, ensure that
all regions that contain private IP addresses are added to the
source address to avoid connectivity loss between those private
IP addresses.
Define the matching criteria for the destination fields in the packet.
In the
Destination tab, set the
Zone.
Specify a
Destination IP Address or leave the
value set to
any.
If you decide to
Negate a
region as the
Destination
Address, ensure that all regions that contain
private IP addresses are added to the
Destination
Address to avoid connectivity loss between those
private IP addresses.
As a best practice, use address objects as the
Destination Address to enable access
to only specific servers or specific groups of servers
especially for commonly exploited services, such as DNS and
SMTP. By restricting users to specific destination server
addresses, you can prevent data exfiltration and
command-and-control traffic from establishing communication
through techniques such as DNS tunneling.
Specify the
Application/Service that the rule will allow
or block.
As a best practice, always use application-based security rules instead
of port-based rules and always set the Service to application-default
unless you're using a more restrictive list of ports than the standard
ports for an application.
Under
Application,
Select
any
Applications,
Application
Groups, or
Application Filters
you want to safely enable. You can select multiple applications or you
can use application groups or application filters. Certain applications
may possess application dependency (also shown as
Depends
on when viewing application details), which you will
need to consider for inclusion into the security rule.
To view application dependency from the security rule:
Select an application and then click Dependent
Applications to display all associated
dependent applications and the rules they are used in.
Additionally, for certain applications, you can select these
dependent applications and either Add To Current
Rule or Add to Another
Rule.
Under
Service, keep the service set to
Application Default to ensure that any
applications that the rule allows are allowed only on their standard
ports. You can also select
Any or
Select specific
Services or
Services
Groups, as necessary.
As a best practice, always use application-based Security policy
rules instead of port-based rules and always set the Service to
application-default unless you're using a more restrictive list
of ports than the standard ports for an application.
(
Optional) Specify a URL category as match criteria for the
rule.
Select URL Category or Tenant
Restriction to specify a specific TCP and/or UDP port
number, a URL category, a tenant restriction as match criteria in the
security rule. If you select a URL category, only web traffic will match the
rule and only if the traffic is destined for that specified category.
Define what action you want the firewall to take for traffic that matches the
rule.
Configure the log settings.
- By default, the rule is set to Log at Session
End. You can disable this setting if you don’t want any logs
generated when traffic matches this rule or you can select
Log at Session Start for more detailed
logging.
- Select a Log Forwarding profile.
As a best practice, don't select the check box to Disable
Server Response Inspection (DSRI). Selecting this option
prevents the inspection of packets from the server to the client. For
the best security posture, both the client-to-server flows and the
server-to-client flows must be inspected to detect and prevent
threats.
Attach security profiles to scan all allowed traffic for threats.
In , select a Profile Group from the
drop-down to attach to the rule.
Select
Save to save the security rule, then
Push Config to your devices.
When you save the security rule, the rule is validated against the configured
security checks. If a security check fails, you can either
Override and Save the rule or
Close and Fix the
issue. You can override and save only if your
role includes the
Override Security Check Block Action
permission.
Monitor the security rule usage status and determine the effectiveness of the
security rule, and
optimize if needed.
