What Is ISA?
  • ISA is Microsoft Internet Security and Acceleration Server 2000
  • ISA is Microsoft’s new Internet firewall and Web-caching server built on Microsoft® Windows® 2000
  • ISA takes advantage of the advanced OS technologies provided by Windows 2000
  • ISA Server can use Microsoft® Active Directory™ to provide centralized and scalable management capabilities
introduction to isa 2000
Introduction to ISA 2000
  • Integrated firewall and Web cache management:
    • ISA protects your internal computers from Internet by installing packet filter
    • ISA server protects all communication between internal computers and the Internet
minimum system requirements
Minimum System Requirements
  • To use Microsoft Internet Security and Acceleration (ISA) Server, you need:
    • A computer with a 300 MHz or faster Pentium II-compatible processor that is running one of these operating systems:
      • Microsoft Windows 2000 Server with Service Pack 1 or later
      • Windows 2000 Advanced Server with Service Pack 1 or later
      • Windows 2000 Datacenter Server
minimum system requirements 2
Minimum System Requirements (2)
  • Additional requirements:
    • 256 MB of RAM
    • 20 MB of available hard-disk space
    • A Windows 2000-compatible network adapter for communicating with the internal network
    • One local hard disk partition formatted with the NTFS file system
migrating from microsoft proxy server 2 0
Migrating from Microsoft Proxy Server 2.0
  • Microsoft Internet Security and Acceleration (ISA) Server supports a full migration path for Microsoft Proxy Server 2.0 users.
  • Most Proxy Server rules, network settings, monitoring configuration, and cache configuration migrate to ISA Server.
  • Furthermore, ISA Server will continue to support Winsock Proxy client software, together with its own firewall client software, in a heterogeneous client base.
why upgrade from proxy 2 0
Why Upgrade from Proxy 2.0?
  • More than 10 times faster than Proxy 2.0
  • Superior Internet access control
  • Scaleable central management
  • Certified enterprise firewall
  • Extensible open platform
internet access
Internet Access
  • ISA Server manages Internet access consistently with access control policies
single management interface
Single Management Interface
  • Administrators benefit from a single management interface for firewall and Web caching
isa server
ISA Server
  • ISA Server is built for enterprise
  • ISA provides tiered policy management
  • ISA allows local array policies; it can inherit policies from enterprise level
  • In distributed environment, administrators can delegate various levels of ISA administration
isa and the network
ISA and the Network
  • ISA Server secures your network, allowing you to implement your business security policy by configuring a broad set of rules that specify which sites, protocols, and content can be passed through the ISA Server computer.
requests and responses
Requests and Responses
  • ISA Server monitors requests and responses between the Internet and internal client computers, controlling who can access which computers on the corporate network.
isa and internal clients
ISA and Internal Clients
  • ISA Server also controls which computers on the Internet can be accessed by internal clients.
firewall and security
Firewall and Security
  • Firewall and security overview:
    • ISA Server can be deployed as dedicated firewall that acts as the secure gateway to the Internet for internal clients
  • Outgoing access policy
  • Intrusion detection
  • Application filters
  • Authentication
  • Security wizard
outgoing access policy
Outgoing Access Policy
  • You can use ISA Server to configure site and content rules and protocol rules that control how your internal clients access the Internet.
  • Site and content rules specify which sites and content can be accessed.
  • Protocol rules indicate whether a particular protocol is accessible for inbound and outbound communication.
intrusion detection
Intrusion Detection
  • Integrated intrusion detection mechanisms can alert you when a specific attack is launched against your network.
security wizard
Security Wizard
  • The ISA Server Security Wizard allows you to set the appropriate level of system security, based on how ISA Server functions in your network.
application filters
Application Filters
  • ISA Server controls application-specific traffic with data-aware filters.
  • ISA Server uses the filters to determine if packets should be accepted, rejected, redirected, or modified.
authentication
Authentication
  • ISA Server supports the following user authentication methods:
    • Integrated Windows authentication
    • Client certificates
    • Digest
    • Basic
extensibility
Extensibility
  • Extensible administration
  • Application filters
  • Web filters
  • Extensible user interface
  • Extensible alerts
  • Extensible storage
