Alarms notify administrators that OPSEC or other controls have failed, been compromised, or circumvented. The application of an alarm control is not difficult if one simple rule is followed: No sensor should exist that is not monitored by a person or other sensor.
Every type of logging or network traffic verification that is monitored to trigger an alarm must be tamperproof. To tamper proof a sensor is to be sure that it cannot be accessed for tampering. To do this, another sensor must be watching that first sensor for unauthorized activity. Each log file should be monitored and an alert sent whenever the log file has been created, deleted, or reduced. Each network sensor should be logged and watched by another network sensor as per its uptime, load, and activity.
