Abstract
A packet gateway may protect TCP/IP networks by enforcing security policies on in-transit packets that are crossing network boundaries. The policies may include packet filtering rules derived from cyber threat intelligence (CTI). The rapid growth in the volume of CTI and in the size of associated CTI-derived policies, coupled with ever-increasing network link speeds and network traffic volume, may cause the costs of sufficient computational resources to be prohibitive. To efficiently process packets, a packet gateway may be provided with at least one probabilistic data structure, such as a Bloom filter, for testing packets to determine if packet data may match a packet filtering rule. Packet filtering rules may be grouped into subsets of rules, and a data structure may be provided for determining a matching subset of rules associated with a particular packet.
