High Performance Proxy
Server With Content Security
To maximize employee productivity, organizations need to ensure a high
quality Internet experience for users. In addition, enterprises need to
implement content and user policies to manage Web traffic growth, while
effectively using network resources. But corporate security cannot be compromised
and Internet performance improvements can't be allowed to impact corporate
security.
BlueCoat Secure Proxy Servers:
First generation proxy servers - software-based applications running
on general-purpose operating systems - offered a point of control for securing
network access. But the performance, degrades under today's heavy Internet
and Intranet usage. In addition, as organizations look to maximize administration
resources, the management, scalability and reliability of these existing
software proxy servers demands improvement. BlueCoat Systems Web security
appliances provide next-generation proxy functionality that delivers business
and technology benefits to Web-dependent enterprises.
BlueCoat Proxy Servers Provide:
-
Optimised appliance for Web security well beyond traditional proxy caching
to enable content security, Web virus scanning and bandwidth management
-
Centralised device management and policy configuration for "one-click"
distribution across all Blue Coat products in the organisation
-
Granular, exceptions-based approach provides flexibility to control exactly
who, what, when, where and how users can access the Web
The BlueCoat Solution
Configured as a proxy caching server deployed between corporate users
and the Internet, these optimized appliances intelligently manage user
requests for content. When a user selects a URL, the request goes first
to the BlueCoat Proxy Appliance for authentication and authorization.
If the objects from the requested page are already in cache on the BlueCoat appliance, they are immediately served to the user. If the objects
are not stored locally, the BlueCoat security appliance acts as a proxy
for the user by communicating to the origin server via the Internet. When
the objects are returned from the origin server a copy is delivered to
the user and also stored on the systems cache to serve all subsequent requests.
The entire transaction is monitored and logged for reporting and planning
purposes.
The BlueCoat Technology Advantage
Blue Coat's unique Web Knowledge Framework allows enterprises to handle
all Web protocols, including HTTP, HTTPS, FTP, Microsoft streaming (MMS
and HTTP streaming), Real streaming (RTSP and HTTP streaming), QuickTime
streaming (over RTSP), MP3, Flash, and hundreds of other Web object types.
Our Patent-pending Policy Process Engine provides the power to define
a comprehensive set of rules for protection, control and acceleration,
and to tie those rules to any number of policy conditions - leveraging
user information in existing directories/databases. The solution uses an
authenticated identifier to trigger all actions and rules. Web requests
can be authorized and managed based on any combination of known identifiers.
The examples below illustrate the powerful policies that are possible
using BlueCoat Systems:
-
Security administrators facing a new security threat could implement a
policy that restricts the use of browsers susceptible to a security flaw,
and only allow access to certain web sites that are mission critical to
business operations for a given group of users.
-
Network managers with a need to control access to Web resources could create
a policy that allowed access to multimedia content only to users with membership
in the group marketing, using Microsoft Media Player, requesting an .asp
file, from www.media.com, during the hours of 8am and 5pm, and using the
HTTP protocol. BlueCoat's Web virus scanning enables security and network
administrators to assure that the files stored in the proxy cache are safe
and free from virus, worms and other network threats. Without virus scanning
this content, existing proxy caches simply serve dangerous content more
quickly.
All Web transactions through the Security Servers are logged,
providing detailed accounting information. This gives the visibility necessary
to determine web usage patterns, audit user history, track security issues,
and develop comprehensive web protection and control policy.
