Overview

The idea of breaking down the behavior of attackers in targeted attacks in cyberspace is called the cyber kill chain, and it is used in the study and design of multi-layered defenses that cut off threats at any one of the layers.
Current targeted attack countermeasures are based on this concept, and mainly focus on entrance and exit countermeasures, as well as detection and defense of known and unknown attacks.

On the other hand, malware that successfully infiltrates inside an organization (malware that infects a client terminal) attempts to spread infection or intrusion to other client terminals, MFPs, servers, etc. on the network.

Even if unknown malware can be detected by a Box-type security product at about the same time that malware successfully infiltrates, it is difficult to shut off a terminal already infected with malware from the network or restrict communication. or cost a lot.

Introduces the concept of security measures that limit communication by dynamically disconnecting the client terminal from the network when malware is detected.
