Cisco Cisco Web Security Appliance S380 Guida Utente

Use this guide as a resource to learn about the features of your appliance. The topics are organized in a 
logical order. You might not need to read every chapter in the book. 

You can also use this guide as a reference book. It contains important information, such as network and 
firewall configuration settings, that you can refer to throughout the life of the appliance. 

The guide is distributed as PDF and HTML files. The electronic versions of the guide are available on 
the Cisco IronPort Customer Support site. You can also access the HTML online help version of the book 
directly from the appliance GUI by clicking the Help and Support link in the upper-right corner.

Before you read this guide, review the Quick Start Guide for your appliance and the latest release notes 
for your product. In this guide, it is assumed that you have unpacked the appliance, physically installed 
it in a rack, and turned it on. 

If you have already cabled your appliance to your network, ensure that the default IP address for the 
IronPort appliance does not conflict with other IP addresses on your network. The IP address that is 
pre-configured on the Management port is 

192.168.42.42

PAC File Hosting

AsyncOS for Web 7.5 includes improvements to hosting PAC files on the Web 
Security appliance. 

You can now replace an existing PAC file with a new version of the file with 
the same name. When you upload a PAC file that has the same name of an 
already uploaded PAC file, the GUI asks if you want to replace the current file 
with the new file. 

You can also delete existing PAC files using the Delete button icon.

When you add a new row in the Hostnames for Serving PAC Files Directly 
section, the default PAC file is the first file uploaded to the appliance.

Authentication 
with Machine 
Credentials

In AsyncOS for Web 7.5, you can configure a timeout value to use when it 
processes machine credentials for authentication from Windows machines that uses 
NCSI.

Windows 7 and Windows Vista machines have a feature called Network 
Connectivity Status Indicator (NCSI). When clients on your network use NCSI and 
the Web Security appliance uses NTLMSSP authentication, you should configure 
the appliance so it uses a relatively small timeout value for machine credentials. Do 
this using the 

advancedproxyconfig > authentication

 CLI command:
