# Managing Packet Capture Files

The ATIC Management center captures packets that meet conditions in the packet capture task, and save them into a packet capture file. The packet capture file can be used by the administrator to view attack events, trace attack sources, parse attack packets, and extract fingerprints for obtaining features and details on attackers, so that suitable defense policies can be configured. The packet capture file can also be downloaded to the local for other operations.
