Maximise your resources
The volume of unsolicited bulk correspondence, or spam, is growing by the day. Time spent deleting spam is time wasted, which costs your business money. Any comprehensive information security system should include protection against spam.
Keep mailboxes clean
Kaspersky Anti-Spam detects spam in incoming mail transmitted by SMTP and filters it out before mail is forwarded to the recipient. Depending on configuration, spam can be
delivered to the original address (as initially sent or with changes)
deleted
redirected to a predefined address
Multi-tier filtration
The solution analyses and filters incoming mail in a variety of ways, checking both the mail body and attachments:
formal attributes: sender and recipient address, senders IP address, size, format etc.
search for words and phrases typically used by spammers
Kaspersky® Anti-Spam protects both users of company mail systems and Internet providers from unsolicited mass mailing or spam.
Kaspersky Anti-Spam helps mail system users eliminate unwanted mail. It employs intelligent spam detection technology, which was developed using Kaspersky Lab’s extensive experience in protecting large-scale mail systems.
Features
Protection from spam
Lists. Messages are checked against blacklists of email addresses and sender IP addresses (e.g., DNSBL or DNS-based Blackhole Lists), which are maintained by service providers and public organizations. Administrators can also compile their own whitelists (e.g., friends list) of users, whose messages will automatically be delivered without undergoing analysis.
Analysis of formal attributes. Attributes that are typical of spam messages include modifications of sender addresses, no recipients specified or an excessive number of recipients, and the absence of an IP address in the DNS system. The size and format of messages are also taken into consideration during analysis.
Linguistic heuristic analysis. Both messages and attachments are filtered according to their content, which is scanned for specific word combinations and their distribution within messages.
Signature analysis. When a new spam message is detected, it can be automatically assigned a lexical signature, which is added to the signature database. From this signature, Kaspersky Anti-Spam can recognize the message or modified versions of the message.
Detection of graphic spam. Graphic signatures are created and added to the signature database in the same way as for ordinary spam. Using graphic spam analysis, images rather than words are analyzed in messages that include both images and text. |
