The WCCP server (in this case, a Cisco router) accepts the registration request and sends a WCCP message as an acknowledgment ("This machine found your machine"). WCCP can be used in large network environments. Figure 2.18 shows a CiscoWSA cluster in which a Layer 3 switch redirects Web traffic to the cluster.136 Chapter 2 Network Security Appliances and Cloud ServicesFigure 2.18 CiscoWSA ClusterThe CiscoWSA runs the CiscoAsyncOS operating system. CiscoAsyncOS has a number of features, including the following, which can be used to defend against Web-based threats.Real-time anti-malware adaptive scanning: CiscoWSA can be configured to dynamically select an anti-malware scanning engine based on URL "reputation", content type, and scanner effectiveness. Adaptive scanning is a feature that allows CiscoWSA to detect embedded malware from files such as images, JavaScript, text, and AdobeFlash more quickly and cost-effectively. Adaptive scanning is an additional layer of security on top of the CiscoWSAWeb "reputation" filter, and includes support for Sophos, Webroot, and McAfee.Layer 4 Traffic Monitoring: A feature that allows Cisco WSA to detect and block spyware. Once this feature is enabled, CiscoWSA automatically adds the IP addresses of known malware domains to the site database and blocks such IP addresses.Third-party DLP integration: For compliance and data leakage prevention needs, you can have CiscoWSA redirect all outbound traffic to a third-party DLP appliance and have that appliance do a deep inspection of the content of the traffic. This allows network administrators to inspect the content of Web traffic based on headers, metadata, and file size, and even block users from storing files to various cloud drives (e.g., Dropbox and Google Drive) oo File Reputation: Using threat intelligence from Cisco Talos, File Reputation threat intelligence is updated every 3min~5min.o File sandboxing: When malware is found, CiscoAMP places it in a sandbox to detect its behavior and also
