Query: Gargoyle: A Network-based Insider Attack Resilient Framework for
  Organizations   `Anytime, Anywhere' data access model has become a widespread IT policy in
organizations making insider attacks even more complicated to model, predict
and deter. Here, we propose Gargoyle, a network-based insider attack resilient
framework against the most complex insider threats within a pervasive computing
context. Compared to existing solutions, Gargoyle evaluates the trustworthiness
of an access request context through a new set of contextual attributes called
Network Context Attribute (NCA). NCAs are extracted from the network traffic
and include information such as the user's device capabilities, security-level,
current and prior interactions with other devices, network connection status,
and suspicious online activities. Retrieving such information from the user's
device and its integrated sensors are challenging in terms of device
performance overheads, sensor costs, availability, reliability and
trustworthiness. To address these issues, Gargoyle leverages the capabilities
of Software-Defined Network (SDN) for both policy enforcement and
implementation. In fact, Gargoyle's SDN App can interact with the network
controller to create a `defence-in-depth' protection system. For instance,
Gargoyle can automatically quarantine a suspicious data requestor in the
enterprise network for further investigation or filter out an access request
before engaging a data provider. Finally, instead of employing simplistic
binary rules in access authorizations, Gargoyle incorporates Function-based
Access Control (FBAC) and supports the customization of access policies into a
set of functions (e.g., disabling copy, allowing print) depending on the
perceived trustworthiness of the context.
