Abstract
An information processing apparatus includes: a processor configured to: acquire message data that indicate a message size and a response time of each response message identified from an encrypted packet group; identify, based on the message data, first peak sizes that satisfy a first condition from a first size distribution of the message size of each response message; determine based on the message data, when the first peak sizes include a second peak size different from third peak sizes, whether a first time distribution satisfies a second condition, the third peak sizes being peak sizes of the message size of each response message in a normal state, the first time distribution being a frequency distribution of the response time of each response message having the second peak size; and determine that a service is abnormal, when the first time distribution satisfies the second condition.
