Claim 14:
15. A log collection system comprising:
a log transmission controller configured to be equipped in a moving object; and
a server configured to be disposed at exterior of the moving object,
wherein the log transmission controller includes a first processor and a first memory that stores instructions configured to, when executed by the first processor, cause the first processor to:
acquire a log indicating respective states of a plurality of electronic control units connected to the log transmission controller;
store priority information indicating a priority for transmitting the log to the server;
acquire
a first update instruction, which is an update instruction generated by an update instructor configured to be equipped in the moving object, for instructing to update the priority information that is stored,
a second update instruction, which is an update instruction generated by the server, for instructing to update the priority information, and
a third update instruction, which is an update instruction generated by the server, for instructing to update the priority information;

update the priority information based on the first update instruction, the second update instruction, and the third update instruction; and
transmit the log to the server based on a priority indicated by the priority information that is updated, and

wherein the server includes a second processor and a second memory that stores instructions configured to, when executed by the second processor, cause the second processor to:
receive the log transmitted from the transmitter;
analyze the log received by the server and analyze a security fault generated at the moving object;
generate the second update instruction and the third update instruction for instructing to update the priority information based on an analysis result of the log; and
transmit the second update instruction and the third update instruction to the log transmission controller,

wherein the first update instruction and the second update instruction are instructions to update the priority indicated by the priority information to be higher than a predetermined priority, and
wherein the third update instruction is an instruction to update the priority indicated by the priority to the predetermined priority.
