Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The inventor finds that the existing technology for carrying out security monitoring on the equipment accessed to the network only carries out vulnerability detection and result display on all the equipment accessed to the current network, and cannot realize real-time monitoring and reminding of equipment access, and particularly cannot remind a user that the network is switched and the detection is carried out in a new network environment in time after the network is switched.
In order to solve the above technical problem, an embodiment of the present invention provides a method for reminding access of a device in a network. Fig. 1 shows a flowchart of a method for reminding access of a device in a network according to an embodiment of the invention. Referring to fig. 1, the method may include at least the following steps S102 to S106.
Step S102, when it is monitored that one or more devices access to the current local area network, intercepting a Dynamic Host Configuration Protocol (DHCP) data packet corresponding to each device in the one or more devices.
Step S104, unpacking the DHCP data packet, and acquiring the basic information of each device in the one or more devices based on the unpacked data.
And step S106, performing access reminding of the one or more devices on a display interface, and displaying basic information of the one or more devices.
The reminding method for the equipment access in the network provided by the embodiment of the invention enables a user to timely acquire the current equipment access state and information in the network, further can perform further vulnerability detection based on the indication of the user, improves the user experience, and ensures the network security.
The method for reminding device access in a network provided by the embodiment of the invention can be operated on various types of terminals, such as a Personal Computer (PC) connected with a current local area network, a mobile phone, a tablet computer and the like, and can also be operated on a router.
In step S102, when it is detected that the device accesses the current lan, the DHCP packet corresponding to the device is intercepted.
The current local area network mentioned in the embodiments of the present invention mainly includes a home local area network, and the accessed devices may include various intelligent devices, such as a computer, a mobile phone, a tablet computer, a router, a camera, a child watch, a sweeping robot, and the like.
DHCP (Dynamic Host Configuration Protocol) is a network Protocol of a local area network, works using UDP, and is generally applied to a large local area network environment, and mainly functions to centrally manage and allocate IP addresses, so that a Host in the network environment dynamically obtains information such as IP addresses, gateway addresses, DNS server addresses, and the like, and can improve the utilization rate of the addresses.
When a device accesses a local area network, a DHCP data packet is transmitted between a DHCP client side and a DHCP server of the device for communication. Capturing the transmitted data packets through the packet filtering software, calling a specific protocol stack API (application program interface) to analyze the captured data packets, and determining whether the DHCP data packets exist or not, thereby realizing the interception of the DHCP data packets.
In the above step S104, the intercepted DHCP packet is unpacked to obtain basic information of the accessed device. The basic information of the device mentioned herein may include at least one of a device name, a device type, a device vendor, network address information, and the like. The network address information may include: an IP (Internet Protocol) address and a MAC (Media Access Control) address.
Specifically, after the intercepted DHCP data packet is unpacked, the name (self-owned name), the identification ID, the MAC address, the IP address, and some DHCP text contents of the device accessing the local area network may be obtained from the unpacked data. Further, according to the MAC address of the device, the manufacturer information of the device can be inquired through a specific network interface. Meanwhile, type information of the device may be acquired based on the identification ID of the device.
In the step S106, the access of the device is prompted on the display interface, and the basic information of the access device is displayed.
The display interface provided in the embodiment of the present invention may be a popup window or a main interface of a security detection tool corresponding to the method for prompting the device access in the network provided in the embodiment of the present invention. Wherein the popup and the main interface are always mutually exclusive, that is, the popup does not appear when the main interface is opened.
In practice, the pop-up window may appear in any suitable area of the screen, such as the lower right corner, and may alert the user. In addition, when the device access reminding is performed on the main interface, considering that the content displayed on the main interface is more, the device access reminding can be simplified into that a red dot near a device icon is used for indicating that the device is accessed to the current local area network.
Fig. 2 is a schematic interface diagram illustrating a popup window for performing access reminding when a single device accesses the popup window according to an embodiment of the present invention. As shown in fig. 2, a reminder message "you have a new device to access the network" may be displayed on the top of the pop-up window interface, and information such as the name of the device (e.g., a computer of a big bear), the type of the device (e.g., a mobile device), and the manufacturer (e.g., a Liteon Technology) may be displayed on the pop-up window interface, so that the user may know the access status and information of the device in the current network in time.
Fig. 3 is a schematic interface diagram illustrating a popup window for performing access reminding when a plurality of devices are simultaneously accessed according to another embodiment of the present invention. As shown in fig. 3, a reminder message "you have N new devices to access the network" may be displayed on the top of the pop-up interface, and information such as names, device types, and manufacturers of the devices may be sequentially displayed on the pop-up interface.
In order to enable the popup to comprehensively display the information of the access device, in an optional embodiment of the invention, when access reminding of a plurality of devices is performed on the popup, the size of the popup can be increased in a manner suitable for completely displaying basic information of the plurality of devices.
Further, in order to prevent the user from being interfered by the oversize pop window, the method for reminding the access of the device in the network may further include the following steps:
judging whether the size of the popup window is larger than a preset size or not;
if yes, reducing the size of the popup window to the preset size, and displaying basic information of the plurality of devices in a rolling mode.
By the method, the information of the access equipment is comprehensively displayed, meanwhile, the interference to the user is avoided, and the user experience is improved. The predetermined size mentioned herein can be set according to practical requirements, and the present invention is not limited thereto.
In addition, in order to avoid the interference to the user caused by the long-time stay of the pop-up window on the screen, in an optional embodiment of the present invention, the method for reminding the device access in the network may further include the following steps:
if the cursor is detected not to be hovered on the popup, closing the popup if the operation of the user on the popup is not received within a specified time length from the start of accessing the one or more devices by the popup for reminding;
and if the cursor is detected to be hovering over the popup, keeping the popup, and closing the popup if the operation of the user on the popup is not received within a specified time length from the time when the cursor leaves the popup.
The operation of the popup mentioned here may be, for example, a click operation of any button in the popup interface. The specified time length can be set according to actual requirements, for example, set to 1min, 2min and the like.
In practical applications, users are often reluctant to be confused by various types of pop-windows or other information when they are in certain specific scenes (e.g., playing games, watching movies, etc.).
In an optional embodiment of the present invention, before the access notification of one or more devices is performed by using the pop-up window, the method for notifying the access of the devices in the network may further include a step of determining whether a current interface state of the user is in a specified mode. Accordingly, step S106 may be further implemented as:
if the current interface state of the user is judged to be the designated mode, filtering out the popup window;
and if the current interface state of the user is judged not to be the designated mode, performing access reminding of one or more devices in the popup window, and displaying the basic information of the one or more devices.
The designated mode mentioned here may include at least one of a game mode gm (game mode), a window Maximized mode wm (window Maximized mode), a server mode srv (server mode), a full screen mode fs (fullscreenmode), and a video mode vm (video mode).
How to determine the above-mentioned designated modes is described below:
(1) game mode
A game base is preset, and the game base comprises information of games on the market. When the current interface state of the user is judged, the name or the identification of the currently running process is identified, and whether the process name or the identification is contained in the game library is detected. If yes, judging that the current interface state of the user is a game mode.
(2) Window maximization mode or full screen mode
Whether the current interface state of the user is in a window maximization mode or a full screen mode is judged by detecting whether the area of the current window or picture covers the whole screen. For example, in windows, it can be determined whether the window is maximized by calling the Iszoom function.
For some applications (e.g., outlook, foxmail, etc.), the working interface is usually in the window-maximized state, and the pop-up prompt appears without interfering with the operation of the user. Therefore, the processes of the applications can be filtered when judging whether the current interface state of the user is in a window maximization mode or a full screen mode.
(3) Server mode
And judging whether the current interface state of the user is in a server mode or not by detecting whether a server of the system runs or not.
(4) Video mode
A video player library is preset, and the video player library comprises information of video players on the market. When the current interface state of the user is judged, the name and the identification of the currently running file or process are identified, and whether the name or the identification is contained in the video player library is detected. And if so, judging that the current interface state of the user is the video mode.
By filtering out the popup prompt (namely preventing the popup for accessing the reminder) when the current interface state of the user is judged to be the designated mode, the interference of the popup to the user is reduced, and the use experience of the user is improved.
In an optional embodiment of the present invention, when the basic information of the device includes a device name, after displaying the basic information of one or more devices on the display interface, the method may further include the following steps:
and in response to the naming operation of a user on one or some of the one or more devices displayed on the display interface, modifying the device name of the device displayed on the display interface.
For example, the user may modify the name of the device displayed on the display interface "hua as a cell phone" to the name "cell phone of big bear" with which the user is more familiar, so that the user may more conveniently recognize the accessed device.
In an optional embodiment of the present invention, after step S106 is executed, that is, after the access prompt of the one or more devices is performed on the display interface and the basic information of the one or more devices is displayed, the method may further include the following steps:
and in response to the trust setting of the user on one or some of the one or more devices displayed on the display interface, no longer reminding the access of the device under the current local area network.
This step is explained below with reference to fig. 2 and 3. As shown in fig. 2 and 3, a trust setting button may be provided in the vicinity of basic information of each access device displayed on the display interface, for example, a "no more prompt for this device" button may be provided in the vicinity of the name of the device. The user makes a trust setting for the device corresponding to the button by clicking the "no more prompt for this device" button. At this time, in response to a click operation of the button "no longer prompt this device" by the user, the corresponding device is identified as a trusted device, and when the device is accessed to the current local area network again later, the access of the device is no longer prompted. For example, in the pop-up interface shown in fig. 2, after the user clicks the "no longer prompt this device" button to perform trust setting on the device "computer of big bear", the pop-up interface is converted into the pop-up interface shown in fig. 4. In fig. 4, the device name "computer of big bear" is changed into "computer of trusting-big bear", which indicates that the device has been identified as trustable device and the access of the device in the current lan is no longer reminded. It should be noted that the arrangement of the buttons and the text information in the above figures is only illustrative and does not limit the present invention.
In an optional embodiment of the present invention, the method for reminding device access in a network may further include the following steps:
responding to the detection request operation of the user, carrying out vulnerability detection on one or more accessed devices, and acquiring and displaying vulnerability detection result information.
This step is still described below with reference to fig. 2 to 4. As shown in fig. 2 to 4, a vulnerability detection entry, such as an "immediate detection" button, may be provided on the display interface. A user can initiate a detection request by clicking an 'immediate detection' button in a display interface, at the moment, all accessed devices are subjected to security scanning to detect whether a vulnerability exists or not in response to the detection request of the user, and obtained vulnerability detection result information is displayed.
