A threat management facility detects a device on an enterprise network and determines whether the device is one of a set of managed devices for the enterprise network. When the device is not one of the set of managed devices, the threat management facility may selectively direct the device to a portal that provides support to the user of the device while the device awaits admission to the enterprise network. As the user interacts with the portal, the portal may manage admission of unrecognized devices onto the enterprise network while making efficient use of network administrator resources.

Managing admission of unrecognized devices onto an enterprise network

Methods, systems and computer readable media for rogue device detection are described. The method may include automatically generating one or more dummy network identifiers associated with a wireless network, advertising the one or more dummy network identifiers, and identifying a device as a suspect device based on receiving a connection attempt to at least one of the one or more dummy network identifiers by the device. The method can also include allocating a virtual local area network within the wireless network to process traffic associated with the at least one of the one or more dummy network identifiers, and monitoring network traffic of the suspect device on the virtual local area network. The method can further include, if the monitored network traffic meets an abnormality threshold, determining that the suspect device is a rogue device, and performing an action to protect the wireless network from the rogue device.

System and method for rogue device detection

Methods, systems and computer readable media for rogue access point detection are described.

Point-controlled rogue AP avoidance + rogue AP detection using synchronized security

Methods, systems, and computer readable media for providing and managing security rules and policies are described. In some implementations, a method may include receiving, at a crowdsourcing security policy server, a security policy from a first user account, and providing a crowdsourced security policy user interface including a section corresponding to the security policy configured to make the security policy available for use by other user accounts. The method may also include receiving from one or more of the other user accounts, a security policy rating corresponding to the security policy, and receiving, from one or more of the other user accounts, a user account rating corresponding to the first user account.

Endpoint-controlled rogue AP avoidance + rogue AP detection using synchronized security

A threat management facility detects a device on an enterprise network and determines whether the device is one of a set of managed devices for the enterprise network. When the device is not one of the set of managed devices, the device may be directed to a portal that manages admission of unrecognized devices onto the enterprise network. Based on a response of the unrecognized device to the portal (e.g., if the unrecognized device does not respond to the portal), the device may be listed on an unclaimed device page published by the portal and accessible to authorized users of the enterprise network. An authorized user may claim the unrecognized device from the unclaimed device page and, in the process, may provide additional information regarding the unrecognized device. Once claimed, the previously unrecognized device may be permitted to communicate over the enterprise network.

Portal for managing admission of unrecognized devices to an enterprise network

A threat management facility detects a device on an enterprise network and determines whether the device is one of a set of managed devices for the enterprise network. When the device is not one of the set of managed devices, the threat management facility may determine whether the device is manageable. When the device is unrecognized and unmanageable, a portal may provide support to a user of the device by listing the device on an unclaimed device page published by the portal and accessible to authorized users of the enterprise network. An authorized user may claim the unrecognized device from the unclaimed device page and, in the process, may provide additional information regarding the unrecognized device. Once claimed, the previously unrecognized device may be permitted to communicate over the enterprise network.

Managing claiming of unrecognized devices for admission to an enterprise network

Implementations generally relate methods, systems, and computer readable media for providing threat index based wireless local area networks (WLAN) security and quality of service. In one implementation, a method includes receiving a request from a client device connected to a network via a network link. The method further includes determining a threat index value for the client device. The method further includes determining one or more security policies associated with one or more respective network resources, where each security policy applies one or more rules for allocating one of the network resources. The method further includes determining allocation of one or more of the network resources to the client device based on the one or more security policies and the threat index value.
