A firewall is as good as its policies and the security of its VPN connections. The latest generation of firewalls offers a dizzying array of powerful options; they key to success is to write concise policies that provide the appropriate level of access while maximizing security.
This book covers the leading firewall products: Cisco PIX, Check Point NGX, Microsoft ISA Server, Juniper s NetScreen Firewall, and SonicWall. It describes in plain English what features can be controlled by a policy, and walks the reader through the steps for writing the policy to fit the objective. Because of their vulnerability and their complexity, VPN policies are covered in more depth with numerous tips for troubleshooting remote connections.
. The only book that focuses on creating policies that apply to multiple products.
. Included is a bonus chapter on using Ethereal, the most popular protocol analyzer, to monitor and analyze network traffic.
. Shows what features can be controlled by a policy, and walks you through the steps for writing the policy to fit the objective at hand"

This book presents practical information on the clinical applications of short pulse laser systems and the techniques for optimizing these applications in a manner that will be relevant to a broad audience, including engineering and medical students as well as researchers, clinicians, and technicians. Short pulse laser systems are useful for both subsurface tissue imaging and laser induced thermal therapy (LITT), which hold great promise in cancer diagnostics and treatment. Such laser systems may be used alone or in combination with optically active nanoparticles specifically administered to the tissues of interest for enhanced contrast in imaging and precise heating during LITT. Mathematical and computational models of short pulse laser-tissue interactions that consider the transient radiative transport equation coupled with a bio-heat equation considering the initial transients of laser heating were developed to analyze the laser-tissue interaction during imaging and therapy. Experiments were first performed to characterize the tissue optical properties needed to optimize the dose for thermal therapy. Experiments were then performed on animal models to characterize the heat affected zone for LITT. The experimental measurements were also validated using the computational models.

Thirty-two mostly fictional stories about people who had a brief encounter with Jesus. Provides background about the person, what caused them to have the encounter, how they reacted to meeting and speaking with Jesus and what it did to their subsequent lives. At the end of each story there is a contemporary reflection to help the reader understand how they might have reacted if they had met Jesus face-to-face.

An intriguing collection of 20 poems inspired by the names of the 2009 Kentucky Derby thoroughbreds in the order they finished. The poet explores the spiritual landscape of hope, loss, love, addiction, and the mysterious bond between women and horses.
