To solve problems faced by current power operation and maintenance

it proposes a design scheme of a trusted power operation and maintenance fortress machine.By creating an operation and maintenance work order with corresponding permissions by the operation and maintenance personnel account

it initiates the operation and maintenance.The interaction messages between the operation and maintenance terminals and the object being operated are encrypted

decrypted

and parsed.It carries out the real time monitoring

control

and secondary authorization of high-risk instructions

attack behaviors

and virus file downloading operations

and generates the full process recording

screen recording

and other log audit information of related operations.The practical application shows that this scheme can achieve comprehensive supervision of power operation and maintenance processes such as pre prevention

in-process protection

and post analysis.It standardizes operating procedures

and ensures the safety and controllability of operation and maintenance work.
