Firewall Management

Last updated February 20th, 2024

Most mobile device platforms use built-in firewalls, but don’t provide granular control over firewall settings and activity. With the Knox¬†Platform, you can deploy firewall configurations specifically catered to your enterprise security needs.

Why manage and customize device firewalls?

Default firewalls may not provide your organization with the security and data protection it needs. In fact, some firewalls may not even let you see the rules they are enforcing. However, when configuring firewalls with the Samsung Knox Platform, you can know exactly what policies are deployed and take additional measures to secure your enterprise systems.

With the Samsung Knox Platform, you can:

  • Restrict and redirect Internet access to specific IP addresses and domains
  • Set firewall policies on a per-app or device basis
  • Produce logs reporting the blocked domains that users accessed

Granular control of Internet access

You can limit the permissible network connections to only trusted addresses, by setting the appropriate Internet access restrictions. The Knox Platform offers a variety of restriction methods, all of which can be used together:

  • IP address filters — Allow, deny, and redirect access to specific IP addresses. Configure a filter to apply to transmitted data, received data, or both. Allow or deny both IPv4 and IPv6 formatted addresses.
  • Domain name filters — Allow or deny access to an entire domain or sub-domain.
  • Per-app and device-wide modes — Give specific apps — for example, ones that handle confidential data — stronger firewalls, and all other apps on a device a more lenient firewall configuration.

Log unsafe URL access

The Knox Platform provides visibility into denied attempts to access blocked domains. The improved visibility helps you to remain aware of potential security breaches or insecure browsing practices within your organization.

The Knox Platform logs reports with the following information:

  • App name — The package name of the app attempting to access a blocked domain.
  • Blocked domain URL — The URL of the domain name blocked by your firewall.
  • Timestamp — The time the incident occurred, to assist with troubleshooting incidents.
