7 1 1 Introduction Run McAfee Web Gateway on Riverbed Services Platform to provide localized security at branch offices of your organization without the need for additional hardware. Contents About McAfee Web Gateway on Riverbed Services Platform McAfee Web Gateway overview RSP overview Requirements Deployment scenario About McAfee Web Gateway on Riverbed Services Platform McAfee Web Gateway provides comprehensive web security that can run as a virtual machine. McAfee Web Gateway consolidates key security applications, such as anti-virus, anti-malware, web cache, and URL filtering, into a single solution. Riverbed Services Platform (RSP) runs virtualized services on Riverbed Steelhead WAN optimization appliances. McAfee Web Gateway on RSP is a single-source, in-band package that passes data through the gateway to and from branch office locations. This allows administrators to provide local web security at branch offices without deploying additional hardware. McAfee Web Gateway overview McAfee Web Gateway is a web security product that provides filtering and policy management to defend against blended threats to your network. The gateway protects your network against threats from the web, such as viruses and other malware, inappropriate content, data leaks, and related issues. You can also use the gateway to ensure regulatory compliance and a productive work environment. The gateway connects your network to the web and implements web security rules by filtering the web requests, responses, and any embedded objects in the traffic that is sent to the web (requests) and sent from the web (responses).

8 1 Introduction RSP overview Features McAfee Web Gateway on RSP provides the following functions: AAA proxy functionality for: HTTP, HTTPS, FTP, Instant Messaging Additional proxies for SOCKS, RTSP, MMS User-based policy SSL content inspection Global Threat Intelligence-enabled web filtering Global reputation-based filtering Geolocation-based filtering Malware scanning Comprehensive, customizable application control within web applications Limitations on RSP When deployed on RSP, McAfee Web Gateway has the following limitations: Tested to support a maximum of 500 users Does not support: Hardware accelerator cards High availability Transparent bridge mode Transparent router mode RSP overview RSP consolidates virtualized services on a single Riverbed Steelhead appliance. RSP provides the following benefits: VMware-based virtualization Up to five virtualized services (packages) for each Riverbed Steelhead appliance Support for various service types: In-band The service is positioned in the optimized data path. Out-of-band The service is positioned separately from the optimized data path and provides infrastructure for the remote network. For more information about RSP, see the RSP User Guide at 8 McAfee Web Gateway Installation Guide for Riverbed Services Platform

9 Introduction Requirements 1 Requirements McAfee Web Gateway runs on Riverbed Steelhead appliances that meet the following requirements: Riverbed Steelhead appliance with 64-bit processor Riverbed Optimization System (RiOS) version 6.0 or later RSP version 6.0 or later, installed and licensed Available RSP slot 35 GB of free disk space 2 GB of free memory Deployment scenario McAfee recommends the following deployment scenario. In this scenario, the gateway is deployed in-band between RiOS and the Riverbed Steelhead appliance WAN interface. As a result, network traffic passes through the Riverbed Steelhead appliance and the gateway. In the data center, the gateway is deployed independently from the Riverbed Steelhead appliance. Additional configurations are available, but not tested. Figure 1-1 In-band deployment This deployment offers the following advantages: McAfee Web Gateway Installation Guide for Riverbed Services Platform 9

10 1 Introduction Deployment scenario A full next generation web security gateway, including: Global Threat Intelligence-empowered URL filtering Malware protection SSL Scanning URL filtering Virus protection Full Microsoft Active Directory integration for authentication and flexible policy control All of these running on the Riverbed Steelhead appliance Figure 1-2 In-band protection for the data center and branch office How the network traffic is processed is determined by its destination. The table shows how traffic destined for a remote LAN is processed compared to traffic destined for the Internet. Table 1-1 Traffic processing based on destination Traffic destination Processing Remote LAN 1 McAfee Web Gateway is configured as the proxy for web browsers and will proxy web traffic in general based on its policy, which can include destinations in the remote LAN. 2 RiOS determines that the destination is behind another Riverbed Steelhead appliance and optimizes traffic. Internet 1 When the traffic reaches McAfee Web Gateway, the traffic is filtered and continues to the Internet only if the security policy allows it. 2 RiOS determines that the destination is not behind another Riverbed Steelhead appliance and does not optimize the traffic. 10 McAfee Web Gateway Installation Guide for Riverbed Services Platform
