Web Security Appliance (WSA)

The WSA main features are  L4 Traffic Monitor and Web Proxy. Other features are – URL filtering – Web usage controls – Application visibility & control – Anti-Malware scanning (Sophos, McAfee, Webroot) Secure web proxy monitors and scans web traffic for malicious  content. When you enable the web proxy, you can configure it to be in transparent or explicit forward  mode The L4 Traffic Monitor detects and blocks rogue traffic across all ports and IP addresses. The L4 Traffic Monitor listens to network traffic that comes in over all ports and IP addresses on the appliance and matches domain names and IP addresses against entries in its own  database tables to determine whether to allow outgoing traffic. L4 Traffic Monitor deployment is independent of the Web Proxy deployment. You can connect the L4 Traffic Monitor to a network tap or the mirror/span port of a switch. When you enable the web proxy, you can configure it to be in transparent or explicit forward mode. Deployment Features you enable determine how you deploy and physically connect the appliance to the network. Two main deployment methods are Explicit forward proxy and Transparent Proxy. Explicit Forward Proxy: Client applications, such as web browsers, are aware of the Web Proxy and must be configured to point to a single Web Security appliance. This deployment requires a connection to a standard network switch. When you deploy the Web Proxy in explicit forward mode, you can place it anywhere in the network. IP spoofing is disabled by default ON – IP address of original source is maintained. OFF – Changing IP address to WSA IP address Automatic: Configure each client application to use a PAC file to detect the appliance Web […]
