Communication systems, including cellular networks, and the devices that are connected to them, can have both legitimate and illegitimate uses. Such communication systems, including systems that utilize, permit, or leverage machine-type-communications, may benefit from monitoring for suspicious events. A method can include receiving a monitoring request regarding a user equipment or a category of devices. The method can also include performing a monitoring activity regarding the user equipment or the category of devices with respect to at least one suspicious event. The method can further include responding to the monitoring request indicating whether monitoring will be performed for the user equipment or the category of devices.
