First embodiment
Referring to figure 3., Fig. 3 is a kind of stream for camera Internet of Things mimicry means of defence that first embodiment of the invention provides
Cheng Tu, the method are applied to electronic equipment.Process shown in Fig. 3 will be described in detail below, the method includes：
Step S110：Obtain the request data package that outside access end is interacted with camera internet of things equipment.
Optionally, electronic equipment can be obtained by way of installation monitoring programme or log collection or traffic monitoring
The request data package that outside access end is interacted with camera internet of things equipment, wherein the request data package is from access end to institute
State camera initiation.
Step S120：Based on the request data package, judgement can with whether the behavior that the camera interacts belongs to
Doubt attack.
Certainly, before judging whether to belong to suspected attack behavior with the behavior that the camera interacts, electronics is set
It is standby request data package to be parsed, obtain the source IP and request content of the request data package.
Wherein, the source can be the IP for issuing the access end of interbehavior with IP, and the request content can be described
The content that access end is requested access to the camera, the content requested access to include access character.
As an alternative embodiment, whether belonging to suspicious attack with the behavior that the camera interacts in judgement
When hitting behavior, may include：
Judging that the source IP is not belonging to pre-set white list range, or is judging that the request content is wrapped
When the character contained belongs to the character in predetermined attack character repertoire, judge that the behavior interacted with the camera belongs to
Suspected attack behavior starts mimicry protection mode to camera, and intercepts the interbehavior.
Otherwise, judge that the behavior interacted with the camera is not belonging to suspected attack behavior, and to the camera shooting
The behavior that head interacts is let pass.
As another optional embodiment, it when electronic equipment parses request data package, can parse pre-
If the multiple request data packages got in the period obtain source IP, the request content of each request data package,
And the request number of times in the difference source IP.At this point, whether belonging to suspicious attack with the behavior that the camera interacts in judgement
When hitting behavior, may include：
Judging that the source IP is not belonging to pre-set white list range, or is judging that the request content is wrapped
The character contained belong to it is predetermined attack character repertoire in character or the request number of times be greater than preset value when, judgement with
The behavior that the camera interacts belongs to suspected attack behavior, starts mimicry protection mode to camera, and intercept the friendship
Mutual behavior.
Otherwise, judge that the behavior interacted with the camera is not belonging to suspected attack behavior, and to the camera shooting
The behavior that head interacts is let pass.
Wherein, the source IP of multiple non-suspicious interbehaviors of characterization is saved within the scope of pre-set white list, in advance
The attack character of multiple suspicious interbehaviors of characterization is saved in determining attack character repertoire.
Step S130：When judgement belongs to suspected attack behavior, to the corresponding outside access end of the suspected attack behavior
Return to modified response data packet.
Wherein, it is non-camera that the modified response data packet, which characterizes the identity of the camera,.
Optionally, modified response data packet is returned to the corresponding outside access end of the suspected attack behavior, it can be with
Including：
The port of the former response data packet of modification and/or protocol type and/or data field, obtain modified response data
Packet；The modified response data packet is returned to the corresponding outside access end of the suspected attack behavior.
Second embodiment

According to packet.
Wherein, it is non-camera that the modified response data packet, which is used to characterize the identity of the camera,.
Optionally, the judgment module 420, specifically can be used for：
The request data package is parsed, source IP, the request content of the request data package are obtained；Judging the source
IP is not belonging to pre-set white list range or is judging that it is predetermined that character that the request content is included belongs to
When attacking the character in character repertoire, judgement belongs to suspected attack behavior with the behavior that the camera interacts.
Optionally, the judgment module 420, specifically can be used for：
The multiple request data packages got within a preset period of time are parsed, each request data package is obtained
Source IP, request content, and the request number of times in the difference source IP are judging that the source IP is not belonging to pre-set white name
Single range, or in the character for judging that character that the request content is included belongs in predetermined attack character repertoire, or
When request number of times described in person is greater than preset value, judgement belongs to suspected attack behavior with the behavior that the camera interacts.
Optionally, the judgment module 430, specifically can be used for：
The port of the former response data packet of modification and/or protocol type and/or data field, obtain modified response data
Packet；The modified response data packet is returned to the corresponding outside access end of the suspected attack behavior.
Optionally, the acquisition module 410, specifically can be used for：
By way of installation monitoring programme or log collection or traffic monitoring, outside access end and camera object are obtained
The request data package of networked devices interaction.
The present embodiment to the process of the respective function of each Implement of Function Module of camera Internet of Things mimicry protective device 400,
