Modern vehicles are increasingly getting connected within the vehicles, with other systems, leading to more concerns about security. Controller area network (CAN) has become a de-facto standard for connecting internal vehicles' components. However, it lacks security features. Conventional security mechanisms fail to protect in-vehicle networks from attacks, requiring the development of an effective intrusion detection system (IDS). This work develops an IDS for in-vehicle networks called IDS-IVN based on a compact representation of location invariant and time-variant traffic features using deep learning. The IDS-IVN uses convolutional neural and long–short-term memory networks as encoder/decoder functions of autoencoder networks to extract features from raw data and classify them using latent space representation into intrusive and non-intrusive classes. A benchmark real-time ROAD dataset is used to demonstrate the IDS-IVN's performance compared to the existing methods. IDS-IVN reports 99% accuracy with a 0.32% low false-positive rate for detecting intrusions. [ABSTRACT FROM AUTHOR]

This paper proposes an intelligent system, called IDGADS, for detecting algorithmically generated domains in the early stages based on easy and automatic computable features of real domain name system (DNS) traffic quickly without investing time in reverse engineering and/or log monitoring or dependency on external information like WHOIS/DNS response. IDGADS is a supervised deep learning model, trained over 17M domains from the reputed sources. It is implemented in Python and served as a service over the cloud for free testing of the public in the form of a web app. IDGADS is capable of detecting malicious domains up to 99% accuracy. Till 17-April-2020, 1160963 domains have been tested, and it has detected 817069 DGA-generated domains by the users of different countries. Since IDGADS is developed to check DNS queries only, thus it can be installed as the first line of defence in security stack for validating DNS queries before sending to DNS server. [Display omitted] • An intelligent deep learning system for detecting algorithmically generated domains. • Extracted intrinsic features from domain names without any human intervention. • Proposed system as first line of defence system for analyzing real domain names as a web service.
