Abstract
Embodiments of the invention provide for adjusting authentication conditions in real-time. A graph-theoretic data structure is dynamically constructing, having nodes corresponding to received valid and invalid authentication credentials used in attempts to access a system. Based on the graph-theoretic data structure, embodiments compute a probability of an invalid credential being an authentication attempt by a particular type of user. If the probability is beyond a threshold probability, embodiments trigger a security event is to adjust an authentication condition of the system, e.g., to increase or decrease a maximum permissible number of failed login attempts within a certain period of time.
