In a pictographic way, the access of the terminal computer to the target needs to be translated through operation and maintenance safety audit. For example, the operation and maintenance security audit acts as a gatekeeper, and all requests to network devices and servers pass through the gatekeeper. Therefore, the operation and maintenance safety audit can intercept illegal access and malicious attack, carry out command blocking on illegal commands, filter out all illegal access behaviors to target equipment, and carry out audit monitoring on misoperation and illegal operation of internal personnel so as to facilitate the responsibility tracking after the fact.

And the device system cannot be applied to the power monitoring system. Moreover, the conventional bastion machine generally supports the conventional operation and maintenance protocol agents, such as character protocol: SSH, TELNET; the graphic protocol comprises the following steps: RDP, VNC; file transfer protocol: FTP, SFTP; and (3) database access: oracle, SQL Server, DB2, Sybase, Informix, Teradata, MySQL, PostgreSQL. The traditional bastion machine does not support the operation and maintenance protocol or the operation and maintenance tool specific to the power monitoring system, so that auditing of the operation and maintenance protocol specific to the power monitoring system or control of illegal commands and the like are not supported.
In an embodiment of the application, the operation and maintenance auditing method of the substation power monitoring system can be applied to an application environment as shown in fig. 1, namely, the application is applied to a three-layer connection architecture of a mobile bastion machine management side server, a mobile bastion machine device and a secure Ukey access device which are connected with each other through a network or other wireless signals in a mobile bastion machine device. The first terminal 102 is, for example, an operation and maintenance device which communicates with the mobile forter device 104 through a network, the mobile forter communicates with the mobile forter management side server 106 through the network, for example, a power monitoring system server, a secure Ukey access device can be arranged on the operation and maintenance device to ensure that the operation and maintenance device is used through the secure Ukey access device, and an operation and maintenance communication network which communicates with the mobile forter management side server through the mobile forter, for example, the power monitoring system server, is established by using a target account. Specifically, the first terminal 102 may be an operation and maintenance terminal, such as a notebook, a desktop, or an industrial personal computer, and is used for an operation and maintenance operator to send an operation and maintenance operation instruction to the power monitoring system, so that the power monitoring system executes a corresponding operation and maintenance action, and the safe and stable operation of the power monitoring system is ensured. The first terminal 102 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the power monitoring system server may be implemented by an independent server or a server cluster formed by a plurality of servers.

The method and the device can adopt a strong identity verification mode, namely a user name password and safe Ukey two-factor login mode to authenticate the identity of the operation and maintenance user. When an operation and maintenance user operates and maintains a target asset, login authentication is required to be performed firstly under the condition that the operation and maintenance terminal is credible, namely, a legal user account and a password are input, and the mobile bastion device can be used only after the user passes the verification. Therefore, the operation and maintenance operation instructions of the power monitoring system can be audited in real time, the operation of illegal external connection equipment which is not in conformity with the operation of the power monitoring system is avoided, and the operation and maintenance operation safety of the power monitoring system and the use safety of the power monitoring system of the transformer substation are effectively improved.
