DETECTION OVERVIEW

Rare Database Table Access

Risk Factors

After gaining access to a database server, an attacker can create simple SELECT SQL queries to search multiple tables in a database. For example, an attacker might be searching for tables with usernames and credit card information. As a result, an attacker learns where valuable information is located and targets databases for additional attacks.

The system might change the risk score for this detection.
