Аннотация:Micro-segmentation of local networks is an important element of network security. The main goal of micro-segmentation of network is to reduce a risk of compromising hosts during a cyber-attack.In micro-segmented networks, if one of the hosts has been compromised, the malicious code or attacker will be limited in the "horizontal" actions by the micro-segment to which the compromised host belongs. Existing methods of micro-segmentation of networks have operational drawbacks that impede their effective practical application.This article presents a new method of micro-segmentation of local wired and wireless networks based on download-able and wireless access control lists, which allows to achieve a high level of granularity of network access policies by minimizing the microsegment, along with high operational characteristics.
