This object reports the username that was used in a failed web-based login attempt against the device's management interface. An admin monitoring the device's web management portal uses this field, similarly to the SSH equivalent, to detect and characterize unauthorized login attempts against the web interface. If both ciscoUrwbFailSshLoginUser and ciscoUrwbFailWebLoginUser show a burst of failed attempts around the same time, the admin might suspect a coordinated scan hitting the device on multiple management interfaces at once.
