8. What Are Enterprise Policies? Definition An ordered set of access rules and policy elements defined at the enterprise level Options Unless you configure enterprise policies, only array policies apply You can configure enterprise polices to be applied before or after the array policy Configure policy elements that can be used when configuring enterprise or array rules Unless you configure enterprise policies, only array policies apply You can configure enterprise polices to be applied before or after the array policy Configure policy elements that can be used when configuring enterprise or array rules

9. What Are Enterprise Networks? Definition A range of enterprise-level IP addresses that do not cross a security boundary To use enterprise networks, you can: Use the predefined enterprise networks, which are associated with array networks of the same name Define enterprise rules using enterprise networks Use enterprise networks to enable communication between arrays Manage the IP address space in the organization Use the predefined enterprise networks, which are associated with array networks of the same name Define enterprise rules using enterprise networks Use enterprise networks to enable communication between arrays Manage the IP address space in the organization

10. What Are Arrays and Array Policies? Array definition A group of ISA Server 2004 computers that share the same configuration Includes a Configuration Storage server and ISA Server Management computers Requires that ISA Server computers have a similar server configuration A group of ISA Server 2004 computers that share the same configuration Includes a Configuration Storage server and ISA Server Management computers Requires that ISA Server computers have a similar server configuration Array policy definition A set of access rules and publishing rules applied to all array members An array policy definition includes: Policy elements that can define array rules Array networks that define network configuration options A set of access rules and publishing rules applied to all array members An array policy definition includes: Policy elements that can define array rules Array networks that define network configuration options

11. What Are Effective Policies? Definition The resultant policy applied to an array member after the system policy, enterprise policy and the array policy rules are evaluated based on rule order Example: Enterprise policy rules applied before array firewall policy Allow HTTP and HTTPS access to the Internet for all users. Branch office array firewall policy rules Allow all protocol access from the Internal network to the Internet for all authenticated users Allow DNS protocol traffic from branch-office DNS servers Enterprise policy rules applied after array firewall policy Enable DNS protocol traffic from main-office DNS servers Enterprise policy rules applied before array firewall policy Allow HTTP and HTTPS access to the Internet for all users. Branch office array firewall policy rules Allow all protocol access from the Internal network to the Internet for all authenticated users Allow DNS protocol traffic from branch-office DNS servers Enterprise policy rules applied after array firewall policy Enable DNS protocol traffic from main-office DNS servers

12. How Enterprise Edition Integrates with Network Load Balancing Enterprise Edition integrates with network load balancing (NLB) by: NLB configuration is performed using ISA Server Management ISA Server provides NLB health monitoring Each network in an array can be configured for NLB ISA Server enables single affinity so clients always connect to the same ISA Server computer ISA Server supports bi-directional affinity for front- end/back-end firewall scenarios NLB configuration is performed using ISA Server Management ISA Server provides NLB health monitoring Each network in an array can be configured for NLB ISA Server enables single affinity so clients always connect to the same ISA Server computer ISA Server supports bi-directional affinity for front- end/back-end firewall scenarios

13. How Enterprise Edition Enables Virtual Private Networking Network load balancing can be integrated with virtual private networking to enable: Network load balancing for remote access VPNs The VPN clients must connect to the shared IP address Network load balancing for site-to-site VPNs The remote-site VPN server must connect to the shared IP address Client requests are automatically directed to the VPN tunnel owner Tunnel failover is automatically enabled Network load balancing for remote access VPNs The VPN clients must connect to the shared IP address Network load balancing for site-to-site VPNs The remote-site VPN server must connect to the shared IP address Client requests are automatically directed to the VPN tunnel owner Tunnel failover is automatically enabled Deploying a Site-to-Site VPN without NLB will disable automatic failover

14. How Enterprise Edition Enables Distributed Caching Using CARP CARP enables distributed caching: Without duplication of cache content Without network traffic between ISA Server computers That can adjust to the addition or removal of array members That evenly distributes the cache or distributes the cache based on load factors Without duplication of cache content Without network traffic between ISA Server computers That can adjust to the addition or removal of array members That evenly distributes the cache or distributes the cache based on load factors CARP works by: Using a script on the Web client that selects the ISA Server computer that will cache the Web content Using a script on the ISA Server computer to redirect client requests to the ISA Server compute that will cache the Web content Using a script on the Web client that selects the ISA Server computer that will cache the Web content Using a script on the ISA Server computer to redirect client requests to the ISA Server compute that will cache the Web content CARP does not use the shared IP address assigned to a NLB cluster
