Specific embodiment
In order to clearly illustrate the technical characterstic of this programme, below by specific embodiment, and its attached drawing is combined, to this
Invention is described in detail.Following disclosure provides many different embodiments or example is used to realize different knots of the invention
Structure.In order to simplify disclosure of the invention, hereinafter the component of specific examples and setting are described.In addition, the present invention can be with
Repeat reference numerals and/or letter in different examples.This repetition is that for purposes of simplicity and clarity, itself is not indicated
Relationship between various embodiments and/or setting is discussed.It should be noted that illustrated component is not necessarily to scale in the accompanying drawings
It draws.Present invention omits the descriptions to known assemblies and treatment technology and process to avoid the present invention is unnecessarily limiting.
The method for security protection and system for being provided for the embodiments of the invention a kind of BMC serial ports with reference to the accompanying drawing carry out
It is described in detail.
As shown in Figure 2,3, the embodiment of the invention discloses a kind of method for security protection of BMC serial ports, the method includes
Following steps:
S1, BMC serial ports permission is distributed for legitimate user；
S2, by legitimate user's information preservation to legitimate user memory block；
S3, terminal user connect Serial Port Line use serial ports when, to terminal user carry out authentication；
S4, when verifying non-number of pass times and being more than given threshold, lock serial ports.
The distribution that user uses BMC serial ports permission is carried out by BMC administrator, i.e., specified legitimate user, for legitimate user point
With user name and initial password, it is stored in legitimate user information storage area.In embodiments of the present invention, safe to improve system
Property, if desired to the modification of the user name, password of a certain user, can only could be modified by BMC administrator, BMC administrator's
Permission highest.
The information of legitimate user, i.e., corresponding user name and encrypted message are stored by legitimate user memory block, this is deposited
Storage area domain is nonvolatile storage, can use flash storage medium, ensures still to be able to save the letter of user after system is powered down
Breath is not lost.
The username and password information from reception display module transmitting is received by authentication module, and retrieves conjunction
Method user information memory block carries out the comparison of user information legitimacy, comparison process specifically:
Comparison pass through after to receive display module send " TRUE " signal；
It is obstructed out-of-date to reception display module transmission " FALSE " signal to compare；
When continuously comparing obstructed out-of-date disabling serial port function three times, and " ERROR " signal is sent to display module is received.
It prompts user to input user name and password by receiving display module, and correlation is shown according to the input of user
Information, concrete operations are as follows:
When terminal user connects Serial Port Line request operation of serial-port, mentioning for " user name, password please being input " is shown in terminal
Show information, user is prompted to carry out the input of information；
When receiving " TRUE " signal of authentication module transmission, the information of " authentication passes through " is shown；
When receiving " FALSE " signal of authentication module transmission, and display " user name, password mistake, it is please again defeated
Enter " information；
When receiving " ERROR " signal of authentication module transmission, display " refusal uses, and please contact administrator "
Information.
After BMC administrator logs in administration page, allowed to work using the personnel assignment of serial ports, typing legitimate user's
User name and initial password information；In addition BMC administrator be responsible for carry out personal information management, including it is subsequent addition it is legal
The operations such as user, modification user password, deletion user, and audit is monitored using the behavior of serial ports to user, it is ensured that system
Safety.User, which obtains its username and password, to be obtained by way of contact BMC administrator.The user of legitimate user
Name and encrypted message are stored in the nonvolatile storage of BMC.
For terminal user when connecting Serial Port Line using serial ports, terminal user inputs username and password, to user's input
User name and password carry out authentication, when same user's checking number reach still verify three times it is obstructed out-of-date, will locking string
Mouth function, user will be unable to using serial ports, it is necessary to just can be carried out the unlock of serial ports by BMC administrator.When user uses serial ports
It finishes, close serial equipment or exits after its account logs in, there is still a need for the verifyings for carrying out identity when being again coupled to serial ports.
The embodiment of the present invention is arranged authentication module, is to close by BMC by increasing associated security module in BMC
The user of method distributes permission, and user needs to carry out authentication when using BMC serial ports, and serial ports could be used after being verified,
To prevent unauthorized person to improve the safety of BMC to the use of serial ports.The present invention is not needed to existing server master board
Hardware circuit carry out any modification, need to only increase associated security module in BMC by software mode, change software flow is
It can be achieved, to realize practicability height, strong feature can be operated.
As shown in figure 4, the embodiment of the invention also discloses a kind of safety system of BMC serial ports, the system comprises:
Serial ports authority distribution module, for distributing BMC serial ports permission for legitimate user；
Subscriber information storing module is used for legitimate user's information preservation to legitimate user information storage area；
Display module is received, for receiving the user information of terminal user's input and showing；
