This paper shows how to properly achieve elasticity for network firewalls deployed in a cloud environment. Elasticity is the ability to adapt to workload changes by provisioning and de-provisioning resources in an autonomic manner, such that at each point in time the available resources match the current demand as closely as possible. Elasticity for cloud-based firewalls aims to satisfy an agreed-upon...
Software-Defined Networking (SDN) controllers are considered as Network Operating Systems (NOSs) and often viewed as a single point of failure. Detecting which SDN controller is managing a target network is a big step for an attacker to launch specific/effective attacks against it. In this paper, we demonstrate the feasibility of fingerpirinting SDN controllers. We propose techniques allowing an attacker...
Rapid technological advancement has induced widespread adoption of smart, powerful and multi-purpose enduser devices (e.g., phones, tablets, set-top boxes, gaming console etc.) in our daily life. Unfortunately, the available mechanisms for accessing, configuring and controlling these devices are still primitive, and require physical access to the devices. Enabling remote access to these devices through...
Protection and performance are the major requirements for any Intrusion Detection and/or Prevention System (IDPS). Existing IDPSs do not seem to provide a satisfactory method of achieving these two conflicting goals. Intrusion Detection Systems (IDSs) fulfill the network performance requirement but exhibit poor protection under successive attacks. On the other hand, Intrusion Prevention Systems (IPSs)...
Modern production clusters are often shared by multiple types of jobs with different priorities in order to improve resource utilization. Preemption is a common technique employed by MapReduce schedulers to avoid delaying production jobs while allowing the cluster to be shared by other non-production jobs. In addition, it also prevents a large job from occupying too many resources and starving others...
