The processor can split the current session and the previous sessions into action windows. The processor can calculate a window similarity score for each action window of the current session using a pair-wise comparison with action windows of each of the previous sessions. The processor can aggregate the window similarity scores to generate a replay likelihood score for the current session with respect to each of the previous sessions. The processor can classify the current session as a replay attack in response to detecting that a replay likelihood score of the current session exceeds a threshold."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Detecting replay attacks using action windows","description":"An example system includes a processor to receive a current session and previous sessions associated with an account.
