1.6. Wrapping Up

System security is a complex problem. It requires knowledge of the underlying operating systems, the applications running on the host, the network infrastructure, the business goals, and your potential attackers. System security is also divided into phases revolving around the lifecycle of a host. All these aspects must be pulled together in an attempt to keep a host secure and the system usable. As complicated as this may sound, there is hope. Many resources are available to assist in understanding the scope of system security. This book will help you install and configure a secure FreeBSD or OpenBSD system to provide critical services for your organization and hopefully provide insight that will be useful to you as you attempt to tackle the problems that you face.
