Abstract
The configuration of a firewall on an endpoint is secured to prevent changes by unauthorized processes, while permitting changes that are requested by authorized processes. Authorized processes can be stored in a tamper protection cache within a kernel of the operating system of the endpoint and secured with reference to a trust authority external to the operating system. When a process on the endpoint requests a change to the firewall configuration, the requesting process can be checked against the processes listed in the tamper protection cache, and any suitable rules can be applied to limit or prevent changes to firewall configuration.
