Abstract
Methods and apparatus are provided for detecting suspicious network activity, such as in an enterprise network. An exemplary method comprises obtaining network event data for a plurality of user-server communications for a given user, determining a number of distinct servers the user communicated with during a predefined time window; determining a number of distinct servers the user failed in authenticating to during the predefined time window; and assigning a risk score to the user based on the number of distinct servers the user communicated with and the number of distinct servers the user failed in authenticating to during the predefined time window. Generally, the risk score provides a measure of an anomalousness of the user communicating with the number of servers during the predefined time window. An absolute score is optionally assigned based on an evaluation of the number of distinct servers the user communicated with during the predefined time window relative to a predefined threshold number.
