Web berkeley packet filters are a raw interface to data link layers and are a powerful tool for intrusion detection analysis. Web use bpf filtering to quickly reduce large packet captures to a reduced set of results by filtering based on a specific type of traffic. Web 4 lines (3 loc) · 148 bytes. The extrahop system constructs a synthetic packet header from the packet index data and then runs the bpf syntax queries against the packet header to ensure that queries are much faster than scanning the full packet payload.
