Computer error prevention and reduction

A computer system for automatically reducing computer errors, comprising:

• one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage devices, and program instructions stored on at least one of the one or more computer-readable tangible storage devices for execution by at least one of the one or more processors via at least one of the one or more computer-readable memories, wherein the computer system is capable of performing a method comprising:
• in response to detecting an interactive session on a command line interface associated with a computer, dynamically extracting data associated with a user by using a keylogging component and a camera associated with the computer, wherein the extracted data comprises user behavior data and user interaction data based on user interaction with the command line interface;
• based on performed real-time analysis on the extracted data and in response to a command being entered on the command line interface, determining a risk score associated with the entered command, whereby the risk score is used to dynamically determine whether to allow execution of the entered command or prevent execution of the entered command based on a risk that the entered command when executed causes a computer error;
• and
• in response to initiation of the entered command and determining that the risk score is at or above a threshold risk level based on the real-time analysis, automatically preventing the entered command from being executed and taking an additional preventive computing action, wherein the additional preventive computing action is proportional to a determined level at which the risk score exceeds the threshold risk level.

A computer program product for automatically reducing computer errors, comprising:

• one or more tangible computer-readable storage devices and program instructions stored on at least one of the one or more tangible computer-readable storage devices, the program instructions executable by a processor, the program instructions comprising:
• program instructions to, in response to detecting an interactive session on a command line interface associated with a computer, dynamically extract data associated with a user by using a keylogging component and a camera associated with the computer, wherein the extracted data comprises user behavior data and user interaction data based on user interaction with the command line interface;
• program instructions to, based on performed real-time analysis on the extracted data and in response to a command being entered on the command line interface, determine a risk score associated with the entered command, whereby the risk score is used to dynamically determine whether to allow execution of the entered command or prevent execution of the entered command based on a risk that the entered command when executed causes a computer error;
• and
• program instructions to, in response to initiation of the entered command and determining that the risk score is at or above a threshold risk level based on the real-time analysis, automatically prevent the entered command from being executed and taking an additional preventive computing action, wherein the additional preventive computing action is proportional to a determined level at which the risk score exceeds the threshold risk level.
