Abstract
A method and a system for dynamically scanning, filtering, and blocking harmful database queries that would otherwise consume significant resources and adversely impact overall system performance are provided. The method includes: receiving a user request for data from a database, the first request including a query; applying database access rules to the query in order to determine whether the query is potentially harmful; when the query is determined as not potentially harmful, forwarding the request to a server configured to respond to the request; and when the first query is determined as being potentially harmful, transmitting a warning message to the user. The database access rules may include a maximum memory consumption rule and a maximum CPU consumption rule. Machine learning techniques are used for adjusting the database access rules based on historical data.
