LGI_BRK_LIM

   LGI_BRK_LIM specifies the number of failures that can occur at
   login time before the system takes action against a possible
   break-in. The count of failures applies independently to login
   attempts by each user name, terminal, and node. Whenever login
   attempts from any of these sources reach the break-in limit
   specified by LGI_BRK_LIM, the system assumes it is under attack
   and initiates evasive action as specified by the LGI_HID_TIM
   parameter.

   The minimum value is 1. The default value is usually adequate.

   LGI_BRK_LIM is a DYNAMIC parameter.
