1. A control system comprising a computer configured to remotely control at least one of charging and discharging of a power storage device mounted on a control target, wherein:
the computer is configured to transmit a first command indicating charging power or discharging power of the power storage device to the control target via each of a first communication path and a second communication path; and
the control system further includes a determination unit mounted on the control target and configured to:
determine whether or not any one of the first communication path and the second communication path is under a cyberattack by using a second command received by the control target via the first communication path when the computer transmits the first command, and a third command received by the control target via the second communication path when the computer transmits the first command;
in a case where the second command and the third command do not coincide with each other, determine that any one of the first communication path and the second communication path is under the cyberattack;
acquire first power indicating charging power or discharging power of the power storage device when charging or discharging in response to the second command is executed, and second power indicating charging power or discharging power of the power storage device when charging or discharging in response to the third command is executed, and
in a case where the second command and the third command coincide with each other, power indicated by the second command and the first power coincide with each other, and power indicated by the third command and the second power coincide with each other, determine that both the first communication path and the second communication path are not under the cyberattack.
