The core of the application is to provide an alarm device, method, electronic device and computer readable storage medium for an illegal operating system startup item, so as to effectively prevent the startup of a malicious startup item and generate an alarm record to facilitate the operation and maintenance personnel to perform device debugging and automatic operation and maintenance.
In order to more clearly and completely describe the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Generally, when a server performs Secure Boot, that is, Secure Boot, if it is found that a Boot item to be loaded is an illegal Boot item, the server intercepts Boot of the Boot item. However, in the prior art, the related interception condition for the illegal boot item is only currently displayed on the display screen interface or the KVM remote display interface, which has display timeliness and is inconvenient for the operation and maintenance personnel to perform problem analysis and maintenance. In view of this, the present application provides an alarm scheme for an illegal operating system boot entry, which can effectively solve the above problem.
Referring to fig. 1, an embodiment of the present application discloses an alarm device for an illegal operating system boot entry, which is applied to a basic input output system controller (BIOS controller) in a server, and the device includes:
the security verification module 101 is configured to perform security verification on an operating system boot entry through the basic input output system in a security boot process of the server;
a result judgment module 102, configured to judge whether an operating system startup item that fails to be checked exists;
and the alarm interface module 103 is configured to intercept the operating system startup item that fails to be verified, obtain corresponding verification failure information, and send the corresponding verification failure information to the baseboard management controller, so that the baseboard management controller performs interface information display and log recording on the operating system startup item that fails to be verified.
Specifically, the bios (basic Input and Output system), i.e., a basic Input and Output system, is a set of programs that are fixed on a chip on a motherboard in a computer, and stores the most important power-on self-test, hardware initialization program, and service program of the system bottom layer of the computer.
The alarm device provided by the application can specifically utilize the BIOS to realize the safety check and alarm of the starting item of the operating system in the safety starting process of the server system. The Secure Boot is a server operating system Boot method for preventing malicious software from invading, and the malicious software cannot pass the security check, so that the system cannot be infected.
Specifically, in the secure boot process of the server, based on the secure verification module, the application performs the secure verification on the boot items of the operating system, mainly the grub boot items, by using the BIOS. The grub (grand unified bootloader) is a bootable kernel program of a bootable multi-operating system from the GNU project, is an implementation of a multi-boot specification, and allows a user to simultaneously own a plurality of operating systems in a computer and select an operating system which the user wants to run when the computer is booted.
If the operating system boot item which fails to be checked exists, the alarm interface module 103 intercepts the operating system boot item to prevent the boot of the illegal operating system boot item. Meanwhile, the alarm interface module 103 also provides a communication line with a BMC (Baseboard Management Controller), and can send related verification failure information to the BMC, and the BMC performs interface display and log archive recording. Therefore, follow-up maintenance personnel can call the BMC log to perform problem analysis and system maintenance, and debugging efficiency of the maintenance personnel is greatly facilitated.
It should be further noted that, in the present application, the server needs to start the enabling of the secure boot in advance, so as to enter the secure boot mode after the system is powered on and booted. Specifically, for example, a server with a NF5280M5 installed with an operating system may log in to the web in advance, open the remote KVM service, and click a power-on button to power on the server. Then in the process of POST (Power On Self Test), clicking DEL Key to enter a Setup interface, changing CSM Support option to Disable (not enabled), Factory Key Provision option to Enable (enabled), changing Secure boot option to Enable (enabled), and storing and restarting. Therefore, the restarted server automatically enters a Secure boot mode after being powered on and started.
Therefore, the warning device for the illegal operating system startup items disclosed in the embodiment of the application can send the verification failure information of the operating system startup items to the BMC for display and log recording by performing the security verification on the operating system startup items in the server security startup mode and using the warning interface module 103 in communication connection with the BMC, thereby greatly facilitating the problem analysis and system debugging of operation and maintenance personnel and improving the automatic operation and maintenance efficiency for the server.

judging whether the operating system startup item is a signed startup item or not through the basic input and output system based on a preset public key; if so, judging that the starting item of the operating system is successfully verified; if not, the starting item of the operating system is judged to fail to be checked.
Specifically, the process of secure boot may specifically be a process of performing secure verification based on a secret key. When the mainboard leaves a factory, some reliable public keys can be built in, and any operating system or hardware driver which is to be loaded on the mainboard needs to pass the authentication of the public keys. That is, only the program signed by the corresponding private key can pass the public key verification, otherwise, the main board refuses to load and determines it as an illegal program.

the acquired verification failure type information and the acquired startup item configuration information are used as verification failure information; the configuration information of the startup item comprises the name of the startup item, the drive path and the file path of the startup item of the operating system with failed verification.
Specifically, by recording verification failure type information and startup item configuration information in detail, operation and maintenance personnel can be helped to quickly and effectively locate problem faults, and operation and maintenance efficiency is improved.
As a specific embodiment, the warning device for an illegal operating system boot entry disclosed in the embodiment of the present application further includes, on the basis of the foregoing content:
the enabling detection module is used for judging whether the safe starting service of the server is enabled or not before the server is safely started; and if the safety starting service is not enabled, generating corresponding prompt information.
