Probabilistically identifying anomalous honeypot activity
Disclosed herein are methods, systems, and processes for probabilistically identifying anomalous levels of honeypot activity. A honeypot dataset associated with a honeypot network is received and a representative usage value is determined from the honeypot dataset. The representative usage value is identified as being associated with anomalous behavior if the representative usage value deviates from an expected probability distribution. A remediation operation is initiated in the honeypot network in response to the identification of the representative usage value as being associated with the anomalous behavior by virtue of the representative usage value deviating from the expected probability distribution.

determining a representative usage value from the honeypot dataset, wherein the representative usage value comprises a number of connections to a port of the one or more ports or to an application of the one or more applications over the period of time;
identifying the number of connections as being associated with anomalous behavior, wherein the identification is based on a probability of a deviation of the number of connections from a historical average of the number of connections according to an expected probability distribution; and

determine a representative usage value from the honeypot dataset, wherein the representative usage value comprises a number of connections to a port of the one or more ports or to an application of the one or more applications over the period of time;
identify the number of connections as being associated with anomalous behavior, wherein the identification is based on a probability of a deviation of the number of connections from a historical average of the number of connections according to an expected probability distribution; and
