The following figure shows a scenario of insertion attack in which packet "O" has a bad checksum. Why does NIDS let the packet pass through?     Question 10 options:   NIDS cannot detect the packet "O"   NIDS is not allowed to check the checksum of each packet   NIDS does not check single letter packet   NIDS is not programmed to validate the checksum of each packet
