Embodiment 1

[0045] Such as figure 1 and figure 2 As shown, a security flow control device for a mimetic switch, including:

[0046]The security situation awareness module is used to maintain the message feature database and formulate security policies; the message feature database records the message feature tuples related to the security of the mimic switch, and the security policy is a dynamic rule formulated by the current security situation , including message filtering mechanism, external fingerprint and internal fingerprint mapping relationship information;

[0047] The drainage module formulates dynamic drainage strategies, maintains the data path of the security traffic of the mimic switch between the physical port of the mimic switch and the data transfer module, and maintains the data path between the data transfer module and the virtual port of the heterogeneous executive body;

[0048] The data transfer module executes the message parsing process on the traffic from the phy...

Embodiment 2

[0058] Such as image 3 and Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that: the data transfer module sets an executive agent, and the executive agent includes a main executive and a distribution agent module, and the distribution agent module receives data from the physical port of the mimic switch The traffic is redirected to the main executive body and establishes connection with each heterogeneous executive body; the main executive body manages the configuration information, and distributes the configuration information to each heterogeneous executive body through the distribution agent module. Wherein, the main executive is elected from the pool of heterogeneous executives according to the election algorithm specified by the security situation awareness module. In particular, the distribution agent module redirects the traffic from the physical port of the mimic switch to the main executive and establishes SSH connections with each het...

Embodiment 3

[0064] Such as Figure 5 As shown, the difference between this embodiment and embodiment 2 is that a specific common security message is provided, such as protocol messages such as ARP and ICMP, the security flow control method:

[0065] ①Assume that the traffic enters from the physical port 17 of the mimic switch;

[0066] ②The message is captured by the drainage rules of the drainage module and redirected to the data transfer module;

[0067] ③The data transfer module analyzes the external fingerprint carried by the message, that is, the frame mark, and knows that the message enters from port 17, and needs to send it to the corresponding port 17 of the main executive;

[0068] ④The data transfer module completes the fingerprint transformation according to the mapping relationship between the internal fingerprint and the external fingerprint;

[0069] ⑤The message is sent from the data transfer module, carrying the VLAN tag that can be identified by the internal fingerprint...

Abstract

The invention provides a mimic switch safety flow control device and method. The device comprises a security situation awareness module, a drainage module and a data transfer module, and the method for controlling the security flow by using the device comprises the following steps that step 1, the security situation awareness module selects features of a security flow message to be controlled and formulates a security strategy; step 2, the drainage module obtains safety flow message characteristics from a mimicry switch physical port or a heterogeneous executor virtual port, and formulates a dynamic drainage strategy according to the message characteristics; and step 3, the data transfer module completes analysis of the message and then forwards the message to a mimicry switch physical port or a heterogeneous executor virtual port. The mimic switch safety flow control method solves the problems that in mimic switch flow forwarding, message distribution, fingerprint conversion and distribution assignment links are large in development difficulty and too low in efficiency, and the attack difficulty of attackers is greatly increased.

Description

technical field [0001] The invention belongs to the field of network security protection, and in particular relates to a security flow control device and method for a mimic switch. Background technique [0002] As the cyberspace security situation becomes increasingly severe, cyberspace mimicry defense technology emerges as the times require. Mimic defense technology is an active defense mechanism that does not rely on prior knowledge by building a dynamic redundant system architecture and operating mechanism. [0003] A typical mimic defense model consists of an input agent, a functionally equivalent heterogeneous executive, an output arbiter and a feedback controller. The input agent completes the copy and distribution of external input information, the heterogeneous executive body obtains the external input information distributed by the input agent to calculate the output result, the output arbitrator performs multi-mode arbitrator according to the output result and is ...
