Query: Database Intrusion Detection Systems (DIDs): Insider Threat Detection
  via Behavioural-based Anomaly Detection Systems -- A Brief Survey of Concepts
  and Approaches   One of the data security and privacy concerns is of insider threats, where
legitimate users of the system abuse the access privileges they hold. The
insider threat to data security means that an insider steals or leaks sensitive
personal information. Database Intrusion detection systems, specifically
behavioural-based database intrusion detection systems, have been shown
effective in detecting insider attacks. This paper presents background concepts
on database intrusion detection systems in the context of detecting insider
threats and examines existing approaches in the literature on detecting
malicious accesses by an insider to Database Management Systems (DBMS).
