Embodiment Construction

[0039] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0040] see figure 1 As shown, it is a schematic structural diagram of a security defense system provided by an embodiment of the present invention. The system includes a core switch 110 deployed in a private cloud, a security resource pool 120, and multiple terminals, such as a terminal 131, a terminal 132, and a terminal 133. , a terminal 134, the security resource pool 120 includes a micro-isolation subsyst...

Abstract

The invention discloses a security defense system, comprising a core exchange, a security resource pool and a plurality of terminals. The security resource pool comprises a micro-isolation subsystem and a plurality of security components. The core switch is used for directing the received access flow to the secure resource pool, and sending the received access flow to the corresponding terminal after cleaning and protecting each security component in the secure resource pool. Each terminal is used for accepting corresponding access when the received access traffic is determined to be safe traffic based on its own micro-isolation policy. Its own traffic information is reported to the micro-isolation subsystem. The micro-isolation subsystem is used for outputting traffic details and access relationships of each terminal to adjust the micro-isolation policy of the corresponding terminal based on the traffic details and access relationships of each terminal. The technical proposal providedby the embodiment of the invention is used for unified security protection of east-west flow and south-north flow, and the security of the private cloud is enhanced. The invention also discloses a security defense method, which has corresponding technical effect.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a security defense system and method. Background technique [0002] With the application of the Internet in various fields more and more widely, various network attacks are also changing and increasing. In the private cloud built by enterprises and institutions, a large number of terminals may be deployed. Once attacked by the network, it will cause large economic losses to enterprises and institutions. Terminals under network attack are mainly due to weak security defense capabilities or loopholes in the system and application itself. [0003] At present, there are many kinds of network attacks. The traditional defense method is mainly to defend through firewalls. Firewalls are deployed at network ingress and egress to clean incoming and outgoing traffic and intercept attack traffic. [0004] This method is too simple and the defense capability is weak. Once the inter...
