Description
Technical field
The present invention relates to security application technical fields more particularly to a kind of guest virtual machine local account essential information to obtain
Method, apparatus and system.
Background technique
Under virtualized environment, we term it offline virtual machines for the virtual machine in off-mode.Guest virtual machine
Local account essential information is stored in an inner binary file of operating system (such as Windows system), we term it
Account management file.
Under traditional Windows computer usage scenario, the local account base of Windows can be obtained by the following method
This information can also be obtained the local account essential information of Windows virtual machine by this method in the case where virtualizing scene: be passed through
The interface that Windows system provides obtains corresponding local account essential information.What Windows system described here provided connects
Mouth includes Windows API, application program, order etc..
There are two disadvantages for this method: one, this method depends on the operating status of Windows system to be checked, only exists
Windows system to be checked can just acquire the essential information of its local account when running；Two, this method depends on
The interface that Windows system provides, this method is unavailable under non-windows system.
In consideration of it, how independent of guest virtual machine operating system to be checked operating status and independent of guest
Interface that VME operating system provides and the local account essential information for obtaining guest virtual machine becomes needs at present and solves
Technical problem.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of guest virtual machine local account essential information acquisition side

Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, the technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is only
It is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiment of the present invention, ordinary skill people
Member's every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
Fig. 1 shows the process of the guest virtual machine local account essential information acquisition methods of one embodiment of the invention offer
Schematic diagram, as shown in Figure 1, the guest virtual machine local account essential information acquisition methods of the present embodiment are as described below.
101, by the account management file mount of guest virtual machine to be checked into the secure virtual machine pre-established, institute
State the local account essential information that account management file is stored with guest virtual machine.
Wherein, the local account essential information, it may include: user name, the full name of user, user's description, owning user group,
Whether account enables, whether account locks, password is never expired, the opposite mark of account login times, account (relative ID,
Abbreviation RID), the last landing time of account, password be finally arranged the time, account expired time, last time password wrong time,
Password errors number and country /region code etc..
It will be appreciated that under virtualized environment, carry account management file not by guest virtual machine to be checked (such as
Windows virtual machine etc.) operating status influence, when operation/stopping/suspended state can be carried out carry.
102, the account management file of carry is loaded into the memory of the secure virtual machine.
103, the block of information of each of the account management file loaded guest virtual machine local account is extracted.
In a particular application, account management file described in the present embodiment can be the binary file of honeycomb hive structure；
Correspondingly, for example, the step 103 can use registration table processing method or tool, what extraction had loaded
The block of information of each of account management file guest virtual machine local account.
It, can also be with it will be appreciated that the registration table processing method or tool those skilled in the art oneself can realize
It is realized using existing registration table processing method or tool.
Since the account management file is a binary file, so in a particular application, in the step 103
In, it is that each of account management file loaded guest virtual machine local account is sequentially extracted according to sequence from front to back
The block of information at family.
104, semantic analysis is carried out to the block of information of each guest virtual machine local account, extracts the sheet of guest virtual machine
Ground account essential information.
In a particular application, the block of information of guest virtual machine local account described in the present embodiment, comprising: concordance list and data
Body；
The concordance list gives each in the beginning of the block of information of each guest virtual machine local account
The length scale of initial position and this information of the local account essential information of guest virtual machine in current information block；
The data volume is the content-data (character string of such as name on account of the local account essential information of guest virtual machine
Deng)；
Correspondingly, the step 104, it may include the step 104a and 104b being not shown in the figure:
104a, from concordance list obtain each guest virtual machine local account essential information in current information block
The length scale of initial position and this information.
104b, since the initial position of the local account essential information of each guest virtual machine, read this information
Length scale data.
In a particular application, after the step 104b, can also include the steps that 104c is not shown in the figure:
104c, by the data conversion of reading at the data to match with preset rules.
Wherein, the preset rules can be with are as follows:
According to needed in the predetermined local account essential information with Chinese description information, need to English description
Information and the information of number description need to be used, will be needed in the data of reading during the information described with Chinese is converted to by encoding of chinese characters
Text will need to be converted to English by character code with the information of English description in the data of reading, will need to use in the data of reading
The information of number description is converted to decimal data.For example, the description information that the present embodiment predefines the accounts such as user name is read
The data taken need to use Chinese description, and in step 104c, the data that the description information of the accounts such as user name is read are passed through Chinese character
Code conversion is Chinese.For another example, the data of account login times reading are hexadecimal, and in step 104c, account is stepped on
The data that land number is read are converted to decimal data.
Fig. 2 shows the signals of the principle of guest virtual machine local account essential information acquisition methods provided in this embodiment
Figure, in a particular application, as shown in figure 3, guest virtual machine described in the present embodiment can be Windows virtual machine, but this implementation
