Message Search From a single location within the user interface, Message Search allows you to confirm the status of messages that have passed through the appliance. It provides you with information about the , including whether it was delivered or blocked, if the message bounced, if it was quarantined, or held in a queue pending further action. Quarantine Configuration Quarantine Options 7

8 Introducing McAfee and Web Security Virtual Appliance Introduction to the virtual appliance features Feature Description Quarantine digests Allow users to handle quarantined items without involving the administrator. McAfee Quarantine Manager Consolidate quarantine management for McAfee products. Message Transfer Agent Reroute traffic on-the-fly based on criteria set by the administrator. For example, encrypted mail can be rerouted for decryption. Allow the administrator to determine the final status of each message. See a quick view summary of inbound messages by domain with drill-down facilities per domain and undeliverable by domain. Prioritize the redelivery of undeliverable based on domain. Pipeline multiple deliveries to each domain. Rewrite an address on inbound and outbound based on regular expressions defined by the administrator. Strip headers on outbound messages to hide internal network infrastructure. Deliver messages using TLS. Manage certificates. Web reputation and categorization Web Web Policies Scanning Policies [Web reputation and Categorization] McAfee SiteAdvisor Web Reputation Create lists of permitted and denied websites, permit access according to their category using McAfee SiteAdvisor Web Reputation, and carry out remote URL category lookups. You can also specify periods when the access to websites can vary. For example, allow access to sites classified as Monitor Access during the daytime. SiteAdvisor classifies sites according to their behavior or reputation, enabling policies on the appliance to block access or issue warnings about unsuitable websites. It reduces nuisances such as spam and adware that users might receive from some websites. McAfee Global Threat Intelligence Web Categorization Global Threat Intelligence Web Categorization provides a simple to configure feature that enables your organization to understand, filter, control, and monitor Internet usage.

Dashboard The Dashboard provides a single location for you to view summaries of the activities of the appliance, such as the flowing through the appliance, the web traffic being scanned, and the overall system health of the appliance. You can also configure a list of links to tasks that you often use. System Setup Wizard epo Managed Setup You can monitor the status of your appliances and also manage your appliance from epolicy Orchestrator. You can directly manage your appliances from epolicy Orchestrator, without needing to launch the interface for each appliance. In epolicy Orchestrator, the user interface pages that you use to configure and manage your and Web Security Appliances have a familiar look-and-feel to the pages that you find within the appliances. System Cluster Management Cluster management enables you to set up groups of appliances that work together to share your scanning workloads, and to provide redundancy in the event of hardware failure. From these pages you can back up and restore your configurations, push configurations from one appliance to others, and set up load balancing between your appliances. System Virtual Hosting Virtual Hosts For the SMTP protocol, you can specify the addresses where the appliance receives or intercepts traffic on the Inbound Address Pool. Using virtual hosts, a single appliance can appear to behave like several appliances. Each virtual appliance can manage traffic within specified pools of IP addresses, enabling the appliance to provide scanning services to traffic from many customers. System Users, Groups and Services Role-Based User Accounts In addition to the Kerberos authentication method, RADIUS authentication is also available. System Appliance Management System Administration Manage Internal Rescue Image When managing your and Web Security appliances, having the image for each appliance stored on a protected partition on the hard disk of each appliance enables you to remotely reimage your appliances. 9

13 Preparing to Install the Virtual Appliance This information helps you prepare your environment and presents topics to consider before you install the McAfee and Web Security Virtual Appliance. Contents Considerations before installing the virtual appliance Network information you need to collect Operating modes and how they affect network connections Explicit proxy mode Deployment strategies for using the device in a DMZ System requirements Considerations before installing the virtual appliance Consider the following before you start the installation process: Choose your virtual environment: VMware vsphere, VMware vsphere Hypervisor (ESXi), or VMware Server. To achieve optimum performance and throughput in a virtual environment, McAfee recommends that you run the virtual appliance on VMware vsphere. VMware Server is suited to smaller deployments. Use the virtual appliance within your organization behind a correctly configured firewall. The virtual appliance is not a mail server. You must configure your firewall, mail server, and other equipment to route traffic to the virtual appliance. The virtual appliance is not a web server or a caching web proxy server. Do not store or install extra software and files on the virtual appliance unless instructed by the documentation or your support representative. The virtual appliance cannot handle all types of traffic. Explicit proxy mode can route only supported protocols through the virtual appliance. Decide whether you want to use the out of band management interface. Network information you need to collect Gather the following information to complete the configuration: Protocols to scan (HTTP, SMTP, FTP, POP3, ICAP) Host name 13

14 Preparing to Install the Virtual Appliance Operating modes and how they affect network connections Domain name Default gateway LAN1 port IP address and subnet mask LAN2 port IP address and subnet mask Out of band management interface IP address and subnet mask DNS server IP address Operating modes and how they affect network connections The McAfee and Web Security Virtual Appliance can run in three operating modes. Before you install and configure your appliance, you must decide which mode to use. The following operating modes are available: Explicit proxy mode The virtual appliance acts as a proxy server and a mail relay. Transparent router mode The virtual appliance acts as a router. Transparent bridge mode The virtual appliance acts as an Ethernet bridge. The mode you choose determines how you physically connect your virtual appliance to your network. McAfee recommends that you run your virtual appliance in explicit proxy mode. Virtual appliances that run in either of the transparent modes are more difficult to set up and maintain in a virtual environment. Explicit proxy mode In explicit proxy mode, some network devices must be set up explicitly to send traffic to the device. The device then works as a proxy or relay, processing traffic on behalf of the devices. Explicit proxy mode is best suited to networks where client devices connect to the device through a single upstream and downstream device. TIP: This might not be the best option if several network devices must be reconfigured to send traffic to the device. Network and device configuration If the device is set to explicit proxy mode, you must explicitly configure your internal mail server to relay traffic to the device. The device scans the traffic before forwarding it, on behalf of the sender, to the external mail server. The external mail server then forwards the message to the recipient. 14

15 Preparing to Install the Virtual Appliance Explicit proxy mode In a similar way, the network must be configured so that incoming messages from the Internet are delivered to the device, not the internal mail server. Figure 1: Relaying traffic The device scans the traffic before forwarding it, on behalf of the sender, to the internal mail server for delivery, as shown in Figure 1: Relaying traffic. For example, an external mail server can communicate directly with the device, although traffic might pass through several network servers before reaching the device. The perceived path is from the external mail server to the device. Protocols To scan a supported protocol, you must configure your other network servers or client computers to route that protocol through the device, so that no traffic bypasses the device. Firewall rules Explicit proxy mode invalidates any firewall rules set up for client access to the Internet. The firewall sees only the IP address information for the device, not the IP addresses of the clients, so the firewall cannot apply its Internet access rules to the clients. Where to place the device Configure the network devices so that traffic needing to be scanned is sent to the device. This is more important than the location of the device. The router must allow all users to connect to the device. Figure 2: Explicit proxy configuration 15

16 Preparing to Install the Virtual Appliance Deployment strategies for using the device in a DMZ The device must be positioned inside your organization, behind a firewall, as shown in Figure 2: Explicit proxy configuration. Typically, the firewall is configured to block traffic that does not come directly from the device. If you are unsure about your network s topology and how to integrate the device, consult your network expert. Use this configuration if: The device is operating in explicit proxy mode. You are using (SMTP). For this configuration, you must: Configure the external Domain Name System (DNS) servers or Network Address Translation (NAT) on the firewall so that the external mail server delivers mail to the device, not to the internal mail server. Configure the internal mail servers to send messages to the device. That is, the internal mail servers must use the device as a smart host. Ensure that your client devices can deliver messages to the mail servers within your organization. Ensure that your firewall rules are updated. The firewall must accept traffic from the device, but must not accept traffic that comes directly from the client devices. Set up rules to prevent unwanted traffic entering your organization. Deployment strategies for using the device in a DMZ A demilitarized zone (DMZ) is a network separated by a firewall from all other networks, including the Internet and other internal networks. The typical goal behind the implementation of a DMZ is to lock down access to servers that provide services to the Internet, such as . Hackers often gain access to networks by identifying the TCP/UDP ports on which applications are listening for requests, then exploiting known vulnerabilities in applications. Firewalls dramatically reduce the risk of such exploits by controlling access to specific ports on specific servers. The device can be added easily to a DMZ configuration. The way you use the device in a DMZ depends on the protocols you intend to scan. Contents SMTP configuration in a DMZ The DMZ is a good location for encrypting mail. By the time the mail traffic reaches the firewall for the second time (on its way from the DMZ to the internal network), it has been encrypted. Devices which scan SMTP traffic in a DMZ are usually configured in explicit proxy mode. Configuration changes need only be made to the MX records for the mail servers. NOTE: You can use transparent bridge mode when scanning SMTP within a DMZ. However, if you do not control the flow of traffic correctly, the device scans every message twice, once in each direction. For this reason, explicit proxy mode is usually used for SMTP scanning. 16

17 Preparing to Install the Virtual Appliance SMTP configuration in a DMZ Mail relay Figure 3: Device in explicit proxy configuration in a DMZ If you have a mail relay already set up in your DMZ, you can replace the relay with the device. To use your existing firewall policies, give the device the same IP address as the mail relay. Mail gateway SMTP does not provide methods to encrypt mail messages you can use Transport Layer Security (TLS) to encrypt the link, but not the mail messages. As a result, some companies do not allow such traffic on their internal network. To overcome this, they often use a proprietary mail gateway, such as Lotus Notes or Microsoft Exchange, to encrypt the mail traffic before it reaches the internal network. To implement a DMZ configuration using a proprietary mail gateway, add the scanning device to the DMZ on the SMTP side of the gateway. Figure 4: Protecting a mail gateway in DMZ In this situation, configure: 17

18 Preparing to Install the Virtual Appliance Workload management The public MX records to instruct external mail servers to send all inbound mail to the device (instead of the gateway). The device to forward all inbound mail to the mail gateway, and deliver all outbound mail using DNS or an external relay. The mail gateway to forward all inbound mail to the internal mail servers and all other (outbound) mail to the device. The firewall to allow inbound mail that is destined for the device only. NOTE: Firewalls configured to use Network Address Translation (NAT), and that redirect inbound mail to internal mail servers, do not need their public MX records reconfigured. This is because they are directing traffic to the firewall rather than the mail gateway itself. In this case, the firewall must instead be reconfigured to direct inbound mail requests to the device. Workload management The virtual appliance includes its own internal workload management, distributing the scanning load evenly between all appliances configured to work together. You do not need to deploy an external load balancer. System requirements Make sure that your host computer adheres to the system requirements for whichever VMware virtual environment you choose. NOTE: Go to the VMware website to get the system requirements for your VMware product. Additionally, ensure that the virtual machine where you will run McAfee and Web Security Virtual Appliance meets the following minimum system requirements: Option Processor Available virtual memory Free hard disk space Definition Two virtual processors 2 GB 80 GB NOTE: The appliance's interface is optimized for Microsoft Internet Explorer 7.0 or later, and Mozilla Firefox 3.5 or later. 18

19 Sample installation scenarios This section contains information about installing the virtual appliance in different server configurations. Running the virtual appliance as the only virtual machine on the host This information illustrates a possible single server deployment of the virtual appliance on your chosen VMware virtual environment. VMware ESX, VMware vsphere, or VMware ESXi are dedicated servers to the virtual appliance.
