Dynamic authorization of requested actions using adaptive context-based matching

Disclosed embodiments relate to context-based analysis of requested activities. Techniques include building dynamic context profiles for processes based on static parameters of the processes, dynamic parameters of the processes, and detected activity involving the processes; receiving an indication of current runtime activity involving at least one identity; matching the indication of current runtime activity to a dynamic context profile; determining a context-based probability that the current runtime activity is anomalous, suspicious, or non-valid with respect to the dynamic context profile; and performing a control action in association with either the current runtime activity or the process based on whether the current runtime activity is determined to be anomalous, suspicious, or non-valid.
