Securing Your Network From Insiders

1. Limit access. Set strict rules on who has access to production servers, where data is most sensitive, and enforce them
2. Create activity logs. Activate auditing mechanisms and review such logs randomly—and religiously
3. Monitor the network. Establish a separate authentication server that stores monitored data in a secure location that programmers cannot access
4. Hire carefully. Do background checks on all staffers who have access to critical data
5. Regulate hours. Deny employees access to the network during off-hours
