Abstract: In some examples, a network device includes an interface, and a processor to apply a restriction on multicast communication associated with an entity on the interface. The restriction on multicast communication includes detecting, on the interface, a multicast communication pattern associated with the entity, indicating, based on the multicast communication pattern on the interface violating a threshold, that the entity is malicious, and blocking processing of the multicast communication associated with the entity in response to indicating that the entity is malicious.

Abstract: Examples relate to selectively processing network packets. In one example, a computing device may receive, by the networking device, a network packet from a user device operating on the network; determine that the network packet is a search packet, the search packet specifying a particular service associated with a server device; provide a network controller with a query for the particular service; receive, from the network controller, an indication that the particular service is not provided by server devices operating on the network; and determine, based on the receipt of the indication, not to process the search packet.
