Abstract: A computing device can install and execute a kernel-level security agent that interacts with a remote security system as part of a detection loop aimed at defeating malware attacks. The kernel-level security agent can be installed with a firewall policy that can be remotely enabled by the remote security system in order to “contain” the computing device. Accordingly, when the computing device is being used, and a malware attack is detected on the computing device, the remote security system can send an instruction to contain the computing device, which causes the implementation, by an operating system (e.g., a Mac™ operating system) of the computing device, of the firewall policy accessible to the kernel-level security agent. Upon implementation and enforcement of the firewall policy, outgoing data packets from, and incoming data packets to, the computing device that would have been allowed prior to the implementation of the firewall policy are denied.
