A data packet is received. The data packet is a unit of data transmitted across a packet-switched network. A determination is made whether a new connection is detected. The data packet is transmitted using the new connection. In response to determining that a new connection is detected, a connection context for the new connection is added to a current connection context in a dynamic event table. The dynamic event table includes the current connection context, one or more previous connection contexts, and a listing of one or more events. Each event of the one or more events is a malicious activity and is retrieved from a repository. A score for each event is calculated based on the current connection context. Each event in the dynamic event table is prioritized based on the calculated score for each event. The event with the highest score receives the highest priority.
