Securing Control and Data Planes From Reconnaissance Attacks Using Distributed Shadow Controllers, Reactive and Proactive Approaches

QoS-aware composite scheduling using fuzzy proactive and reactive controllers

We consider in this paper downlink scheduling for different traffic classes at the MAC layer of wireless systems based on orthogonal frequency division multiple access (OFDMA), such as the recent 3rd Generation Partnership Project (3GPP) long-term evolution (LTE)/LTE-A wireless standard. Our goal is to provide via the scheduling decisions quality of service (QoS), but also to guarantee fairness...

Proactive and reactive inhibitory control in rats

Inhibiting actions inappropriate for the behavioral context, or inhibitory control, is essential for survival and involves both reactively stopping the current prepared action and proactively adjusting behavioral tendencies to increase future performance. A powerful paradigm widely used in basic and clinical research to study inhibitory control is the stop signal task (SST). Recent years have s...

Securing Manet from Blackhole and Wormhole Attacks

Mobile Ad-Hoc networks are self-configuring and self-organizing multi-hop wireless networks. They do not have any fixed infrastructure or centralized management. Due to this, the ad hoc networks are vulnerable to attacks. The routing protocol for MANET considered in this paper is AODV(Ad hoc On-demand Distance Vector Routing Protocol). Blackhole and Wormhole nodes are malicious nodes which degr...

Securing Cloud Computing from Different Attacks Using Intrusion Detection Systems

Changing proxy-server identities as a proactive moving-target defense against reconnaissance for DDoS attacks

We consider a cloud based multiserver system consisting of a set of replica application servers behind a set of proxy (indirection) servers which interact directly with clients over the Internet. We study a proactive moving-target defense to thwart an attacker’s reconnaissance phase and consequently decreases the success rate of the planned attack. The moving-target defense is a dynamic identit...
