Method, device, and system for providing hot reservation for in-line deployed network functions with multiple network interfaces. A system includes a first Network Function (NF) unit, connected to an ingress router and to an egress router; and a second NF unit, connected to the ingress router and to the egress router. The first NF unit is initially configured as a controlling NF. The second NF unit is initially configured as a backup NF. The two NF units periodically exchange keep-alive messages via the two routers. The second NF unit, operating as the backup NF, automatically triggers a switchover if the second NF unit did not receive a keep-alive message from the first NF unit for at least a pre-defined time-period. Additionally or alternatively, the controlling NF initiates a switchover if the maintenance status parameters of the backup NF are better than those of the controlling NF.

A system monitors network activity of an end-user device that communicates with servers over a communications network. The performs analysis of packets of data that are transported via the network. The system detects a first set of communications in which a first server infects the end-user device with a cryptocurrency mining malware; a second set of communications, in which a second server activates the end-user device as an activated cryptocurrency mining bot; and a third set of communications, in which the second server allocates a cryptocurrency mining task to the end-user device and later receives a cryptocurrency mining output from the end-user device. The system determines that the first server is a malicious infecting web-server; that the second server is a malicious Command and Control server of a distributed bot-net of cryptocurrency mining bots; and that the end-user device is an infected and activated and operational cryptocurrency mining bot.

System, device, and method of deploying layer-3 transparent cloud-based proxy network element. A virtual network function is defined between a west-side router and an east-side router. A west-side interface receives east-bound traffic from a west-side Virtual LAN. East-bound queries from the west-bound router, are intercepted and responded to by the west-side interface, the response indicating the MAC address of the west-side router instead of the east-side router. The system enables the virtual network function to transparently intercept network traffic, and to selectively apply to such traffic one or more network functions or operations, prior to forwarding the traffic or a modified version thereof to the east-side router, in a Layer-3 transparent manner.
