3 ANTI SPAM SOLUTIONS TECHNOLOGY REPORT 3 INTRODUCTION As the war for corporate inboxes intensifies, and unmonitored s disrupt effective and secure working practices, Anti-Spam solutions continue to evolve to deal with this menace. In this, the second Anti-Spam Technology Report, we examine the functionality and performance of the leading products in this market, which are aimed specifically at the SME network environments. A key objective of the testing is to replicate the installation, configuration and use of the solutions in a real-world business environment to enable readers of the White Paper prospective buyers to make a meaningful assessment of the product that is right for protecting their corporate environment. Test Engineers have evaluated how the solutions install to ensure timely and effective spam protection. Consideration has also been given to the level of security administrator expertise and technical support required to facilitate both out-of-the-box operation and thereafter product training to ensure maximum effective spam protection. This reports provides an independent assessment of effectiveness with regard to: The features and functionality of the solution. Integration into a network infrastructure. The level of user administration required to operate the product effectively. Spam detection capability and rates of detection.
4 4 ANTI SPAM SOLUTIONS TECHNOLOGY REPORT TEST NETWORK WCL has a number of domains that collect genuine spam. These domains receive varying levels of spam and are consistent with different environments. To reflect the usage within a corporate environment, within each domain are a number of designated user accounts with a variety of practices and needs including some that are subscribed to a variety of newsgroups and mailing lists. Some user accounts actively contribute to mailing lists. The multiple domains designated for testing purposes were those that, between them, receive spam at a level consistent with the defined requirements of testing. Software solutions included in the test program were installed on servers that meet the minimum specifications required by the vendor. Appliance-based solutions were installed on the network according to the vendor's recommended placing. For hosted services, WCL testes through identified domains and changed the MX records to divert the mail stream through the hosted service.
5 ANTI SPAM SOLUTIONS TECHNOLOGY REPORT 5 TEST METHODOLOGY WCL initially performed the testing with an out-of-the-box configuration, changing only those settings on the solution needed to ensure correct operation in line with the vendor's recommended installation and configuration procedures. Further testing was then performed following the vendor's advice for the tuning or training of the solution under test. WCL fine-tuned the solution each day of the test, spending no more than half an hour per day undertaking such work. Throughout the course of testing, a mixture of was sent to the test domains from other addresses and domains controlled by WCL to mirror genuine activity common in business, for example, requesting meetings, sending notifications to groups and non-business related social s. s were also sent from web-based accounts such as Hotmail and Google's Gmail in order to simulate external users sending non-business related social s, and home workers. Thus, during the testing period the domains received some spam, some list/newsgroup mailings and "genuine" individual s.

9 ANTI SPAM SOLUTIONS TECHNOLOGY REPORT 9 TEST REPORT INTRODUCTION Filter by SurfControl is a software solution designed to be installed on either a Windows 2000 or 2003 Server. The application itself is provided on CD and comes packaged with an impressive amount of literature in the form of installation and administrator guides as well as a getting started guide. These guides are available for both the Report Central and End User Spam Management consoles, providing an administrator with a wealth of information for use during both the setup and operation of the software. For the duration of this test Filter was installed on a Dell Precision 360 running Windows 2000 Server, which was patched using Service Pack 4. Mail was routed through the service from one of the domains wholly owned and controlled by West Coast Labs.
10 10 ANTI SPAM SOLUTIONS TECHNOLOGY REPORT TEST REPORT INSTALLATION AND CONFIGURATION The installation process for Filter is both swift and uncomplicated, this is due to a combination of descriptions for each installation step and the use of a commonly used installation routine for Windows-based software. Any applications required for the proper use of Filter are checked for during installation, and are installed should any be missing or of the wrong version. Once this initial process is complete, the Configuration Wizard is launched, allowing an administrator to further define settings relating to the network on which Filter is to be installed. There are four categories to the Configuration Wizard, split across multiple screens: Your Organization, System Details, Mail Routing, and Filtering Options. If during the install procedure a required port is detected as being in-use, Filter provides the ability to specify an alternative. Throughout the installation, Filter provides clear descriptions of each step and informs the user of the reasons for requesting certain information. The entire installation is over in minutes, with Filter quickly configured and running.
11 ANTI SPAM SOLUTIONS TECHNOLOGY REPORT 11 TEST REPORT INTERFACE Once installed, there are several methods of accessing individual components belonging to Filter. Most of the interfaces are available through two folders located in the start menu: SurfControl Filter and SurfControl Report Central. Within the Filter folder are several programs, all of which can be run independently from a standard Microsoft Console, such as QueueView, Rules Administrator, Monitor, and Message Administrator. Also available within this folder is Dictionary Management, which displays the word and phrase categories that are scanned for by Filter. The initial screen provides a count of the number of entries in each category, and when viewing each category the list of included words and phrases is shown, along with their respective score. Both of these fields can be edited; for example, terms that may normally be associated with pornographic spam can be given a lower score than is awarded by default. Message Administrator provides in-depth information of the messages contained within Filter's various queues. The top half of this console lists the queues, which include virus, offensive, anti-spam agent, and a count of the number of contained messages. Next to this is a window showing the attributes of these messages, including the recipients, subject, dictionary score, and sender. Clicking on each individual message allows the administrator to view the body and any associated files or attachments, and this is displayed in the lower half of this screen. The QueueView is a simplified version of Message Administrator. When launched it lists each queued message along with details including date, time, recipient, sender, and subjects. Also displayed here are the number of attempts to deliver the message and a brief description for the reason of failure. This shortened version allows an administrator to constantly monitor the offending messages that are being detected by Filter. The Rules Administrator console is where the Administrator controls the actions that Filter
12 12 ANTI SPAM SOLUTIONS TECHNOLOGY REPORT TEST REPORT performs on every categorized message. The top half of the screen lists each rule present on Filter and whether they are currently active. Clicking on one of the rules displays how the rule works in an intuitive If-Then diagram, and the creation of rules from within this console is made easy by a simple drag and drop interface. This method of displaying and creating rules is a refreshing approach and provides a very quick and easy way to configure Filter. For remote administration there is a web interface available, which listens on a non-standard port. The left hand side of the interface provides a menu, from where each of the message queues can be viewed. Clicking on one of the queues displays the messages contained, including standard information such as the sender and recipient addresses, along with the subject and date. Below this the queues are links to the Logs and the Dictionary Management, with the latter providing the same level of customization as available in the console described earlier. Finally a.pdf version of the Administrator's Guide is available for local download.
13 ANTI SPAM SOLUTIONS TECHNOLOGY REPORT 13 TEST REPORT REPORTING Information is available to the user in two ways, either through the SurfControl Monitor or via the Report Central Java-based web interface. The latter, Report Central, may be launched from the second of the two start menu folders mentioned earlier. When the interface is launched, the user is presented with a login screen. Once logged in, the Administrator may choose from two individual report types: Standard Reports and Custom/Scheduled Reports. Selecting one of these displays the categories that are available to the administrator. For example, under Standard Reports, the administrator can select to view reports based on either rules or traffic statistics, each with an array of individual reports available. Rules reports may be viewed by date, various levels of sender details, and various categories of most common rules used by Filter. Each of the ten reports available under the Rules Reports tab contain eight fields that may be further customized, these include rules, weekday, recipients, recipient domains, options, date/time, senders, and sender domains. The second report type to be found under Standard Reports is traffic statistics. Like the Rules Reports this category also contains ten individual reports, which break the traffic down into categories including bandwidth by date, bandwidth by hour, messages by size, and messages by weekday. Also included within the traffic statistics category are reports displaying the top 15 recipients, sender by total messages, and total size. Should the administrator wish to customize what information is generated in a report, these particular settings and configurations can be saved under customized/scheduled reports. By allowing the administrator to save customized reports, very specific reports can be generated time and again without having to continuously specify the same options.

16 16 ANTI SPAM SOLUTIONS TECHNOLOGY REPORT SECURITY FEATURES BUYERS GUIDE DEVELOPMENTS IN THE PRODUCT OVER THE LAST 12 MONTHS AS STATED BY SURFCONTROL Over the last year SurfControl Filter for SMTP has been enhanced to not only help organization's better address their spam threat, but also address the broader risks posed by including viruses, phishing attacks, spyware, confidential data loss and regulatory violations. These enhancements include new compliance-related dictionaries and pre-configured compliance rules that help customers meet corporate governance and regulatory requirements. Support of Transport Layer Security (TLS) and Secure SMTP (SMTPS) allows Filter to send and receive encrypted traffic, protecting the privacy of s while being transmitted across the Internet. The implementation of Sender Policy Framework (SPF) helps to guard against spoofed s, phishing, fraud and spam and helps distinguish authentic messages from forgeries. Other new features have given administrators and end-users improved visibility and control over spam and other related threats. New market-leading reporting now incorporates additional high level dashboard and forensic-style, drill-down reports. The addition of connection-level reporting gives customers exceptional visibility of the threats targeted at their infrastructure and allows them to see the effectiveness of connection-level anti-spam measures such as Real-time Black Lists (RBLs), Directory Harvest Attack and Denial of Service protection and take effective measures to protect against such threats. The message search capability has been significantly enhanced to reduce the administrative burden of managing isolated spam and other s. Also, improvements to Filter's end-user management tool, Personal Manager, provide comprehensive administration of isolated s at the end-user level, resulting for greater productivity for both administrators and end-users.
