Enable sinkhole VPN mitigation for iOS devices

Network threats can be mitigated using a sinkhole VPN profile in the MTD Local Actions policy. Once you enable the MTD Local Actions Network Sinkhole option, you can optionally specify specific IP addresses, domains, and countries through the Threat Management Console. See Sinkhole mitigation by IP address, domain, or country.

NOTE:

MobileIron recommends selecting the Network Sinkhole action ONLY for network-related threats. Use of Network Sinkhole action for device and application threats can result in disabling network connectivity to the device without the ability to restore network connectivity.

Before you begin 

• Make sure you have reviewed Creating MTD local actions in Core.

Procedure
