Technical Field
The invention belongs to the technical field of mimicry defense, and particularly relates to an efficient mimicry judging device and method.
Background
The mimicry defense technology changes the game rules of network space defense and provides a brand-new solution for realizing network security of network equipment. The mimicry defense system is generally composed of an input broker, a pool of heterogeneous executives, a resolver, and a scheduler. The input agent copies and distributes the external message to each heterogeneous executive body, and the input agent does not monitor whether the heterogeneous executive body fails or not; heterogeneous executables are typically implemented by operating systems or hardware modules with equivalent functionality; the resolver receives a message sent by the heterogeneous executive body, and judges whether the heterogeneous executive body is attacked or not through a mode of 'majority resolution' and the like; the scheduler is matched with the threat information output by the arbitration module to complete the dynamic scheduling of the heterogeneous executer. Although the judgment method can quickly detect the external attack, the judgment is difficult to be carried out due to the self fault of the heterogeneous executive body, so that the judgment of the resolver is mistakenly judged and the external attack is caused, and the problem of low judgment efficiency of the resolver is caused.

Detailed Description
The technical solution of the present invention is further described in detail by the following embodiments.
Example 1
as shown in fig. 1, an efficient mimicry defense system includes an input agent, a heterogeneous executive pool, and a resolver, and further includes:
The fault detector is used for detecting whether the heterogeneous executors in the heterogeneous executors pool have faults and recording the faults, and meanwhile, sending fault messages to the fault collector;
The fault collector is used for collecting fault information sent by the fault detector and sending the fault information to the fault recovery module, the resolver and the input agent; receiving fault recovery information sent by a fault recovery module, and sending the fault recovery information to a resolver and an input agent;
The fault recovery module is used for receiving fault information sent by the fault collector and setting software or hardware of the heterogeneous executer with the fault; and receiving heterogeneous executive body fault recovery information and transmitting the heterogeneous executive body fault recovery information to a fault collector.
As shown in fig. 2, the method for performing mimicry defense by using the high-efficiency mimicry defense system of the present embodiment includes the following steps:
step 1: the fault detector detects the running state of the heterogeneous executive hardware and software in real time, sends the detected fault information to the fault collector, and then the fault collector transmits the fault information to the resolver, the input agent and the fault recovery module;
Step 2: the resolver removes the resolution of the fault heterogeneous executive message;
And step 3: the input agent removes the distribution of the input message of the fault heterogeneous executive body;
and 4, step 4: the fault recovery module sends a setting command to the heterogeneous executive body with the fault or resets the heterogeneous executive body in a hardware mode;
after the fault recovery module resets the heterogeneous executive body, the fault recovery module receives the fault information of the heterogeneous executive body again within the specified time and removes the fault heterogeneous executive body from the mimicry defense system;
After the heterogeneous executive body recovers the fault, the fault recovery module informs the fault collector, the fault collector eliminates the fault record of the heterogeneous executive body and informs the arbitrator and the input agent to rejoin the message arbitration and distribution of the heterogeneous executive body.
example 2
The present embodiment is different from embodiment 1 in that, as shown in fig. 3 and 4: the fault detector comprises a heartbeat message transmitter designed on each heterogeneous execution body, and the fault collector is a heartbeat monitor. The heartbeat message comprises power supply and peripheral equipment states, a cpu utilization rate, a memory utilization rate, a software process state and a nos id of the corresponding heterogeneous executive.
the heartbeat detection function in the embodiment consists of a heartbeat message sender and a heartbeat monitor part; in order to monitor the running state of each heterogeneous executive body in real time, each heterogeneous executive body is provided with a heartbeat message transmitter; the heartbeat message sender sends heartbeat messages to the heartbeat monitor at regular time, the heartbeat messages contain the running state information (such as cpu utilization rate, memory utilization rate, whether each software process is normal or not and nos id) of the current heterogeneous executive body, the heartbeat monitor analyzes and judges the heartbeat messages after receiving the heartbeat messages, and after identifying abnormal information, the heterogeneous executive body is considered to have a fault; meanwhile, when the heartbeat monitoring module does not receive the heartbeat message within the specified time, the heterogeneous executive body is also judged to have a fault.
After judging that the heterogeneous executive body has a fault, the heartbeat monitoring module sends the nos id information of the heterogeneous executive body to the input agent, the resolver and the fault recovery module; after receiving the fault information, the input agent removes the fault executive from the input distribution queue, and does not distribute the message to the fault heterogeneous executive any more, so as to reduce unnecessary resource overhead of the input agent; after receiving the fault information, the resolver removes the heterogeneous executive bodies from the current resolution queue, so that the problem of low efficiency of the resolver caused by long-time waiting for the fault heterogeneous executive bodies to send resolution data is avoided; and after receiving the fault information, the fault recovery module restarts the heterogeneous executive body, and if the fault information of the current heterogeneous executive body is received again within the specified time, the fault recovery module completely puts the heterogeneous executive body off line. After the heterogeneous executive body executes the restart operation, the heartbeat monitor receives the heartbeat message again, and then informs the input agent and the arbitrator to add the heterogeneous executive body into the data distribution queue and the arbitrating queue again.
finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will understand that: modifications to the specific embodiments of the invention or equivalent substitutions for parts of the technical features may be made; without departing from the spirit of the present invention, it is intended to cover all aspects of the invention as defined by the appended claims.
