  7. Verified Effectiveness • West Coast Labs • Industry recognized spam testing facility • Premium Antispam certification • Requires 97% catch rate • Forefront Security for ExchangeBeta 2 Test Results • 99% spam catch rate • False positive rate of 0.0005%

  8. FSE Antispam Deployment Edge Internal Network Exchange Edge Exchange Hub Exchange Mailbox Spam Exchange CAS User

  9. SMTP Send Delivery Queue SMTP Receive Submission Queue Categorizer SMTP SMTP Recipient API Ex Submit (MAPI -> SMTP) Pickup Directory Exchange Biz Logic • Exchange Integration • Forefront is built on the top of Exchange’s publically documented Transport APIs • Forefront premium antispam agents can be deployed separately or in conjunction with basic Exchange agents (excluding Content Filter) • Forefront architecture is highly adaptive, extensible, and engine independent. Forefront Antispam Transport Agent/Message API Agent Run Time Engine (MEx) AD

  10. FSE Antispam ProtectionAreas of analysis • IP Source • SMTP / Envelope • Content • Outlook client integration

  11. FSE Antispam ProtectionIP Source Related • IP Allow / Deny Lists • DNSBL • Microsoft Hosted – No additional cost • Aggregates multiple RBL feeds

  12. FSE and DNSBLHow it works • 1. Forefront DNSBL agent is triggered by connection request from the Internet FSE-protected Exchange server • Response • Match returns 127.0.0.x code (drop)No match returns NXDOMAIN (accept) • Microsoft hosted DNSBL is totally transparentThere is nothing additional to purchase or configure Forefront DNSBL agent constructs and sends a specially formatted DNS query to the Microsoft hosted DNSBL server I N T E R N E T Connecting Client 3. Microsoft hosted DNSBL server validates and responds to the query FOSE DNSBL Servers

  13. FSE Antispam ProtectionSMTP Envelope / Data Related • Per Organization • Backscatter Protection • SenderID Verification • Global Sender Filtering • Global Recipient Filtering • Global Exclusion List • Per Recipient • Safe / Blocked Senders • Safe / Blocked Recipients

  14. FSE SenderID FilteringHow it works • 1. Forefront agent is triggered by connection request from the Internet FSE-protected Exchange server • Support for current and legacy representation of DNS entries • SPF 1.0 and SPF 2.0 • DNS record types TXT and SPF (type 99)x Forefront SenderID agent queries the sending mail domain’s DNS server I N T E R N E T 3. Mail senders’s DNS responds to the query Connecting Client 4. Forefront SenderID agent verifies IP of connecting client is authorized to send mail for the domain Mail Domains DNS Servers

  15. FSE Antispam ProtectionContentRelated • New content filtering agent • Integration of Cloudmark Authority ® technology • Carrier grade performance, accuracy and protection • Configurable ranges for certain vs. suspect spam allowing for deletion or quarantine of gray-mail • Forefront Keyword Filtering • Forefront True File Type Filtering

  16. Cloudmark® Content Fingerprinting Fingerprint Cache Spam Reject Legit. FSE-protected Exchange recipient • Message preprocessing occurs to normalize content • Relevant parts of the message are analyzed • Message components reduced to a short set of anonymous fingerprints • Fingerprints compared to local cache of known bad fingerprints • Match :message is identified as abuse • No match: Heuristics are applied • No match & No heuristics: message is identified as legitimate

  17. Content Filter Spam Confidence Level • All “good” e-mail gets assigned an SCL of -1 • Forefront will reassign an SCL of -1 to all mail determined to be in the range of 0 – 4 by the content analyzer. • Prevents re-evaluation by Outlook • E-mail within 5 to 9 is subject to the following actions: • Reject • Delete • Stamp and Continue • Quarantine

  18. FSE Antispam ProtectionOutlook Client Related • No more junk mail… almost • Mail determined to be clean is delivered directly to the user’s inbox • User’s custom settings are evaluated on the server

  28. BackscatterThe Problem • ‘Backscatter spam’ gums up many e-mail inboxes • Dubbed backscatter spam, this latest fad is clogging email accounts and slowing victims’ inboxes to a crawl. Up to 3% of all email today is backscatter… http://www.usatoday.com/tech/news/2008-10-20-backspatter-spam_N.htm • 90% of FOSE bounce messages are backscatter • 6 million / day • Number 2 customer complaint

  29. FOSE Backscatter ProtectionHow it works – Valid NDR I N T E R N E T Valid User (you@example.com) FOSE Receiving Mail Server • 1. Outbound customers sends email through FOSE 3. Receiver cannot deliver, must send bounce message The FOSE Server inserts custom tokens • 4. FOSE Inbound Server looks for tokens 5. Tokens exist, deliver NDR to user <prvs=12we34fnr=you@example.com>

  30. FOSE Backscatter Protection • How it works – Backscatter NDR I N T E R N E T Valid User (you@example.com) Receiving Mail Server FOSE Spammer 1. Spammer generates an email with a forged MAIL FROM address and sends to receiving email server<you@example.com> 3. FOSE Inbound Server looks for tokens 4. No tokens exist! Message is backscatter spam! Receiver cannot deliver, must send bounce message

  31. Outbound Spam Mitigation FOSE Regular Outbound Customer 1 Customer 2 Customer 3 FOSE NDR Pool FOSE Spam Filter

  33. Hybrid Solution Bringing together on-premise and hosted protection

  34. FOSE GatewayThe bridge between on-premisee and the cloud • Managed from on-premise systems • Forefront Code Name Stirling console • FSE Stand alone UI • Synchronizes on-premise data with FOSE • Active Directory information • FSE Antispam policy • Collects data from FOSE to on-premise systems • Quarantine information • Statistics

  35. FOSE Gateway – Policy ManagementHow it works I N T E R N E T FOSE Gateway FOSEBackend Forefront Stirling Console Forefront Edge Server 1. Antispam policy defined on Stirling Console 3. FOSE Gateway pushes policy to FOSE Backend via web service call 2. Policy assigned to asset group and pushed out to Edge Server and FOSE Gateway 4. Antispam policy put into effect on FOSE Backend

  36. FOSE Gateway – Data CollectionHow it works I N T E R N E T FOSE Gateway FOSEBackend Forefront Code Name Stirling Console 1. FOSE Server makes scheduled web service calls to FOSE Backend to collect quarantine and statistics information 2. FOSE Gateway sends data to the Stirling Server for centralized storage 3. FOSE information available to administrator alongside on-premise data via the Stirling Console
