CC-FIDS: a federated intrusion detection system with low false negative rates via category consensus and hierarchical filtering

Journal of King Saud University: Computer and Information Sciences
In federated intrusion detection, the non-independent and identically distributed (non-IID) nature of data leads to an imbalanced distribution of tail attack categories across edge devices. This imbalance amplifies category bias after global aggregation,

Securing Cyberspace

, 2017
Cyber-security is thus a very serious issue. Attacks can have catastrophic consequences. The cyber-war is for real. Greater legal certainty, less confrontation between departments and more cooperation between governments, is the call of the hour. India has to make cyber-security a priority, if the government wants to go digital. Attitudes and behaviour
