    A framework for reasoning about the human in the loop

    Get PDF
    Many secure systems rely on a \u27human in the loop\u27 to perform security-critical functions. However, humans often fail in their security roles. Whenever possible, secure system designers should find ways of keeping humans out of the loop. However, there are some tasks for which feasible or cost effective alternatives to humans are not available. In these cases secure system designers should engineer their systems to support the humans in the loop and maximize their chances of performing their security-critical functions successfully. This paper proposes a framework for reasoning about the human in the loop that provides a systematic approach to identifying potential causes for human failure. This framework can be used by system designers to identify problem areas before a system is built and proactively address deficiencies. System operators can also use this framework to analyze the root cause of security failures that have been attributed to \u27human error.\u27 Examples are provided to illustrate the applicability of this framework to a variety of secure systems design problems, including anti-phishing warnings and password policies
