Guest Editorial: Special Issue on Behavior Data Analytics for Cybersecurity

Abstract

With rapid development of smart cities and digital economy, cybersecurity has already become the cornerstone to ensure the resilience of the entire ecosystem. On top of traditional systems/data/network security research, cybersecurity is facing new challenges. This is mainly due to the increasing scale of complex collaboration among stakeholders on a loosely regulated network of insecure devices. Advances in hacking and malware techniques, including APTs (advanced persistent threats), fileless malware, zero-days exploits, …, etc. already make active in-time defense difficult to achieve. Even worse, insider threats and human factors have already moved to the top in the main security threat list. Conventional security measures often find to be ineffective when dealing with them; and all these are just magnifying the negative impacts of cyber-attacks.
