Query: Decentralised firewall for malware detection   This paper describes the design and development of a decentralized firewall
system powered by a novel malware detection engine. The firewall is built using
blockchain technology. The detection engine aims to classify Portable
Executable (PE) files as malicious or benign. File classification is carried
out using a deep belief neural network (DBN) as the detection engine. Our
approach is to model the files as grayscale images and use the DBN to classify
those images into the aforementioned two classes. An extensive data set of
10,000 files is used to train the DBN. Validation is carried out using 4,000
files previously unexposed to the network. The final result of whether to allow
or block a file is obtained by arriving at a proof of work based consensus in
the blockchain network.
