In the foreseen 5G and beyond networks, billions of wireless devices will participate in big data aggregation and smart automation in order to interface the cyber and physical worlds. Such large-scale ultra-dense wireless connectivity is vulnerable to malicious software (malware) epidemics. In particular, malware worms can exploit different forms of device-to-device communications to stealthily compromise large numbers of devices without being noticed by security servers at the core network. Compromised devices can then be used by adversaries to remotely launch cyberattacks that cause large-scale critical physical damage and threaten public safety. This talk will introduce and motivate a percolation theoretic approach to characterize and thwart malware diffusion in dense wireless networks. First, a brief tutorial on percolation theory will be introduced. Then, the talk will explain the utilization of percolation theory to develop security countermeasures for malware epidemics in 5G and beyond networks.
