What is ISA Server 2004
• Microsoft Internet Security and Acceleration
(ISA) Server 2004 is the advanced stateful
packet and application-layer inspection
firewall, virtual private network (VPN), and
Web cache solution that enables enterprise
customers to easily maximize existing
information technology (IT) investments by
improving network security and performance.
ISA Server 2004 is available in two versions:
standard edition and enterprise edition.
What is ISA Server 2004
• ISA Server is particularly well suited for
protecting large enterprise network
configurations requiring multiple firewall
arrays in disparate locations that are running
Microsoft client and server applications, such
as Microsoft Office, Office Outlook Web
Access 2003, Office SharePoint Portal Server
2003, Internet Information Services (IIS),
Routing and Remote Access, Active Directory
directory service, and many other Microsoft
applications, servers, and services.
What is ISA Server 2004
• ISA Server contains a full featured,
application-layer aware firewall that helps
protect organizations of all sizes from attack by
both external and internal threats. ISA Server
performs deep inspection of Internet protocols
such as Hypertext Transfer Protocol (HTTP),
which enables it to detect many threats that
traditional firewalls cannot detect. The firewall
also provides VPN client inspection for
Microsoft Windows Server 2003-based
quarantine solutions, helping to protect
networks from attacks that enter through a
VPN connection.

What is Cache
• An area of disk space which stores the
text and graphics of a viewed web page.
When the web page is revisited, the Web
browser will retrieve the data from the
cache instead of downloading it again to
save time.
What is Cache
• Or, is an area on the hard disc of a computer
where web pages and page elements (graphics
etc) are stored when a page is downloaded
from the Internet. If a page is revisited and the
page, or elements of the page, are still held in
cache then the computer will use the cache
version to save time rather than download
afresh. It also allows previously visited pages
to be viewed offline.
