With the availability of its latest firmware release 5.1, the Barracuda Spam & Virus Firewall continues to expand its feature set to offer customers more capabilities to secure their email infrastructure. Customers with current Energize Update Subscriptions can download this new firmware update. Major new features in this release are outlined below. Internal Email Protection With the Barracuda Microsoft Exchange Anti-Virus Agent, organizations can now protect their internal emails using the same virus definitions used by the Barracuda Spam & Virus Firewall. Viruses can easily be transmitted internally through the use of Outlook Web Access from home PCs, public kiosks and other machines not under the organization’s control. This can also apply to POP and IMAP if external access is allowed, and unauthorized machines are used to send email. Uploaded files can then be transmitted as email attachments to others within the organization. The agent, an add-in, runs as a Windows service on the Microsoft Exchange Server and enables the server to scan internal email for viruses. Via the agent, the Microsoft Exchange Server will receive constant virus definition updates. Seamless Encryption with Microsoft Outlook Senders now have the option to mark emails for encryption within Microsoft Outlook. The Barracuda Microsoft Outlook add-in includes an Encrypt Message button. While composing a message, the sender can mark the email for encryption using the Encrypt button and then send it. The encrypting process will be done by the Barracuda Spam & Virus Firewall and integrates with the existing outbound email encryption feature. Email Encryption Branding This release allows organizations to brand encryption notification emails as well as encrypted messages. The branding configuration is done on the Barracuda Spam & Virus Firewall on a per-domain level. Administrators can create custom subject and text or html message content in any language for the notification email. Encrypted messages on the Barracuda Message Center can be branded with a logo image and a domain name. IPv6 Email Transport New IPv6 support provides email receipt and delivery over IPv6 networks. The Barracuda Spam & Virus Firewall can receive email traffic from an IPv6 network, apply content policies, and deliver email traffic to either an IPv4 or IPv6 network. Email traffic can also be redirected by policy to an IPv6 server. Barracuda Reputation, DNS, and other Layer 3 checks will continue to be IPv4 only. Outbound Sender Based Rate Control To protect against compromised systems on internal networks sending high volume spam, Sender Based Rate Control feature for outbound emails is now based on the number of recipients. If the number of recipients from a sender exceeds the configured maximum in a 30-minute time window, the Barracuda Spam & Virus Firewall will defer further messages from the sender. Enhanced Barracuda Control Center Integration With this release, administrators can centrally manage more global policies of the Barracuda Spam & Virus Firewall using Barracuda Networks’ centralized management application, the Barracuda Control Center. Administrators can manage Basic features, Block/Accept policies, and most Advanced features. The Barracuda Control Center provides a single view for configuration and management of multiple Barracuda Spam & Virus Firewalls. The Barracuda Spam & Virus 5.1 firmware release includes additional user interface and mail processing enhancements. Please take a look at the 5.1 release notes for the details.
