Welcome to Firewalls For Dummies, a book written to help the average
Joe understand how firewalls work and how to configure a firewall.
This book meets the needs of the person just finding out about computers,
as well as the network administrator who needs to implement his or her first
Hàng phòng vệ đầu tiên chống lại những kẻ hay đi xâm nhập trộm là firewall: một tập hợp những thủ thuật chuyên môn có thể giúp ngăn chặn ý đồ xâm nhập xấu vào máy tính và hạn chế những gì đi ra khỏi máy. Windows cũng bao gồm một firewall riêng và router (giúp kết nối máy tính với Internet) cũng có router riêng. Trong bài viết này, chúng tôi sẽ giải thích firewall là gì, chúng hoạt động như thế nào và làm thế nào chúng giúp máy tính được bảo vệ an toàn.
Check Point Access Control Solution
A Security Gateway at the network boundary inspects and provides access control for all traffic. Traffic that does not pass though the gateway is not controlled. A security administrator is responsible for implementing company security policy. The Security Management Server enables administrators to enforce security policies consistently across multiple gateways. To do this, the administrator defines a company-wide security policy Rule Base using SmartDashboard and installs it to the Security Management Server.

The Grid is a highly dynamic environment. The standards governing grid services are currently
being defined and software implementations are subject to revision. The resources available are
continually being expanded and changing in configuration. The user community is geographically
widely distributed and volatile. Managing security in this environment, whilst retaining the desired
level of accessibility for users is a challenge for software designers, implementers and site

This module provides students with the knowledge and skills that they will need
to design a complex installation of multiple products on a single server. After
completing this module, students will be able to:
Choose a hardware platform.
Determine the Microsoft® Windows® 2000 operating system configuration
for the Web infrastructure servers.
Select the appropriate technology for a highly available solution based on
Microsoft Internet Information Services (IIS).
Design a highly available COM+ (Component Object Model) Environment
by using Microsoft Application Center 2000.
Check Point IPS is an Intrusion Prevention System (IPS). Whereas the Security Gateway firewall lets you
block traffic based on source, destination and port information, IPS adds another line of defense by
analyzing traffic contents to check if it is a risk to your network. IPS protects both clients and servers, and
lets you control the network usage of certain applications. The new, hybrid IPS detection engine provides
multiple defense layers which allows it excellent detection and prevention capabilities of known threats, and
in many cases future attacks as well.
When the need arises to protect selected user workstations from intrusion and virus epidemics,
the administrator usually has to visit each computer to manually install and configure its firewall
to comply with corporate security policies. Practically always, the same settings and tools are
used with each workstation. In complex distributed networks this requires an administrator to
spend a lot of time duplicating the same sets of operations multiple times. Moreover, the
administrator must manually reapply all modifications made by each individual user.
