Barracuda Networks announced the Predictive Sender Profiling capabilities of the Barracuda Spam Firewall.Ã‚Â These capabilities provide industry-leading protection against spammers’ latest attempts to evade traditional reputation analysis.Ã‚Â Utilizing a network of more than 40,000 customer systems worldwide, Barracuda Networks has the most diverse compilation of email available for profiling the behavior of spammers.Ã‚Â Using this data enables the Barracuda Spam Firewall to more easily determine a sender’s identity when identity obfuscation techniques are used.
Modern spam trends require reputation data be augmented with behavioral profiling techniques.Ã‚Â For example, by taking control of networks of computers infected with malware, spammers can send email from diverse sources throughout the Internet, thus hiding their own identity from traditional reputation checks that profile sender network addresses.Ã‚Â By registering new domains or by redirecting to spam Web domains through reputable blogs, free Web site providers, or URL redirection services, spammers have also learned to hide their identity from traditional reputation checks that profile spam Web domains.
When spammers obfuscate their identities, the Barracuda Spam Firewall can profile behaviors of all senders.Ã‚Â Examples include:
” Sending too many emails from a single network address.Ã‚Â The Barracuda Spam Firewall prevents spamming behavior from an email server even when it does not have a previously established reputation for doing so.
” Attempting to send to too many invalid recipients.Ã‚Â The Barracuda Spam Firewall automatically rejects SMTP connection attempts from email senders that attempt to send to too many invalid recipients, a behavior indicative of directory harvest or dictionary attacks.
” Sending email blasts on the first day after registering a domain.Ã‚Â Barracuda Central maintains domain reputations and automatically adds newly registered domains to Intent Analysis databases.
” Using free Internet services to redirect to known spam domains.Ã‚Â Ã‚Â Barracuda Spam Firewalls with Multilevel Intent Analysis enabled, automatically follow URL redirections from free Internet services and analyze the reputation of the destination Web sites and their associated DNS configurations.
