Plan the Installation
Decide how you are going to configure the Cisco S190 Web Security Appliance
within your network.
The Cisco S190 appliance is typically installed as an additional layer in the
network between clients and the Internet. Depending on how you deploy the
appliance, you may or may not need a Layer 4 (L4) switch or a WCCP router to
direct client traffic to the appliance.
Deployment options include:
• Transparent Proxy—Web proxy with an L4 switch
• Transparent Proxy—Web proxy with a WCCP router
• Explicit Forward Proxy—Connection to a network switch
• L4 Traffic Monitor—Ethernet tap (simplex or duplex)
–
Simplex Mode: Port T1 receives all outgoing traffic, and port T2
receives all incoming traffic.
–
Duplex Mode: Port T1 receives all incoming and outgoing traffic.
Security Services
L4 Traffic Monitor: • Monitor only
• Block
Acceptable Use Controls: Enable
• IronPort URL Filters
• Cisco IronPort Web
Usage Controls
Web Reputation Filters: Enable
Malware and Spyware Scanning: • Enable Webroot
• Enable McAfee
• Enable Sophos
Action for Detected Malware: • Monitor only
• Block
IronPort Data Security Filtering: Enable

Note To monitor true client IP addresses, the L4 traffic monitor should
always be configured inside the firewall and before NAT (Network
Address Translation).
If your installation includes multiple Cisco Web Security Appliances (S-Series)
or Cisco Email Security Appliances (C-Series), you may want to also use a Cisco
Content Security Management Appliance (M-Series) to manage them, as shown
in the following network diagram:

Install the Appliance in a Rack
Install the Cisco S190 Web Security Appliance using either the slide rails or fixed
rack mount brackets. For information about these installation options, see the
Cisco x90 Series Content Security Appliances Installation and Maintenance
Guide.
Appliance Placement in a Rack
• Ambient Temperature—To prevent the appliance from overheating, do not
operate it in an area that exceeds an ambient temperature of 104°F (40°C).
• Air Flow—Be sure that there is adequate air flow around the appliance.
• Mechanical Loading—Be sure that the appliance is level and stable to avoid
any hazardous conditions.

Plug In the Appliance
Plug the female end of the power cable into the power supply on the back panel
of the appliance. Plug the male end into an electrical outlet.
Temporarily Change Your IP Address for Remote
Access
To remotely configure the Cisco S190 using the network connection, you must
temporarily change the IP address of your computer. Alternatively, you can use
the serial console to configure the Cisco S190, without changing the IP address.
If you use the serial console, proceed to section 8 below.
Note Make a note of your current IP configuration settings because you will
need to revert to these settings after you finish the configuration.
For Windows
Step 1 Connect your laptop to the primary Management Port (labeled M1)
using the cross over or Ethernet cable included in the system box. The
Cisco S190 appliance uses the M1 Management port only.
Step 2 Go to the Start menu and choose Control Panel.
Step 3 Double-click Network and Sharing Center.
Step 4 Click Local Area Connection and then click Properties.
Step 5 Select Internet Protocol (TCP/IP) and then click Properties.
Step 6 Select Use the Following IP Address.

• IP Address: 192.168.42.43
• Subnet Mask: 255.255.255.0
• Default Gateway: 192.168.42.1
Step 8 Click OK and Close to exit the dialog box.
For Mac
Step 1 Launch the Apple menu and choose System Preferences.
