ISA Server 2004 Management Interface

ISA Server 2004 Enterprise Edition Features ISA Server 2004 Enterprise Edition provides enhanced scalability by: Providing centralized storage and configuration of the ISA Server configuration data Supporting CARP for distributed caching Providing NLB integration

Differences Between ISA Server 2000 and ISA Server 2004 Multiple network support Policies assigned per network Routed and NAT network relationships Extended protocol support Advanced application filtering Enhanced authentication options VPN and quarantine integration Stateful inspection for VPN Export and import Delegated permissions wizard for firewall administrator roles

Lesson: Deployment Scenarios for ISA Server 2004 How ISA Server Works as an Internet Edge Firewall How ISA Server Works as a Back-End Firewall How ISA Server Works as a Branch Office Firewall How ISA Server Works as an Integrated Firewall, Proxy, and Caching Server How ISA Server Works as a Proxy- and Caching-Only Server

How ISA Server Works as an Internet Edge Firewall Use ISA Server to: Block all Internet traffic unless explicitly allowed Publish internal servers such as Web or Exchange servers Provide a VPN gateway for remote users Provide LAN proxy and Webcaching services Server ISA Server Web Serve r VP N Intern et Serve r User Exchange Server Remote User

How ISA Server Works as a Back-End Firewall Use ISA Server to: Securely publish Exchange servers Securely publish other internal Web servers Provide proxy and caching services LAN Web Server ISA Server Serve r Firew all Web Serve r Intern et User Exchange Server Remote User

How ISA Server Works as a Branch Office Firewall Use ISA Server to: Create an IPSec tunnel-mode VPN between offices Create a PPTP or L 2 TP with IPSec VPN between offices Inspect and filter all traffic between offices LAN Provide secure ISAaccess Server to the branch office or other VPN gateway Serve r User Intern et Corporate Headquarters ISA Server Internet LAN at the VPN Branch Office Tunnel

How ISA Server Works as an Integrated Firewall, Proxy, and Caching Server Use ISA Server to: Provide proxy and caching services to conserve Internet bandwidth Configure dial-up connections to the Internet Block all inbound network traffic Provide secure configurations using network templates and server publishing wizards LAN ISP Server ISA Server Serve r Intern et Web Server User

How ISA Server Works as a Proxy- and Caching-Only Server Use ISA Server with a single network adapter to provide proxy and caching services Deploying ISA Server with a single network adapter means that it does not provide additional security functionality LAN ISA Server Web Serve r Firewa ll User Intern et
