Kaspersky Security for Linux Mail Server

Key Features

Integrated protection against viruses and spam 

Improved!Advanced antivirus engine
Kaspersky Security for Linux Mail Server includes the latest version of Kaspersky Lab’s award-winning antivirus engine – with behaviour stream signatures – to help detect and remove malicious attachments from incoming emails.

New!Zero-Day Exploit and Targeted Attack (ZETA) Shield
Kaspersky’s ZetaShield offers protection against unknown malware and exploits – to defend you from zero-day and zero-hour attacks and APTs (Advanced Persistent Threats).

Improved!Powerful Anti-Spam Engine
Kaspersky Security for Linux Mail Server provides the latest version of Kaspersky’s anti-spam engine – including two powerful new technologies:

  • Enforced Anti-Spam Updates Service – uses push technology, directly from the Kaspersky cloud, to deliver real-time updates. By reducing the ‘update window’ from 20 minutes to approximately 1 minute, the Enforced Anti-Spam Updates Service helps to defend businesses against zero-hour spam and spam epidemics.
  • Cloud-assisted Reputation Filtering – fights against unknown spam, to enhance the spam capture rate and reduce the number of false positives.

New!Kaspersky Security Network
The cloud-based Kaspersky Security Network (KSN) gathers data from millions of participating users’ systems around the world to help defend your system from the very latest viruses and malware attacks. Potential threats are monitored and analysed – in real-time – to help block dangerous actions, before harm is caused.

Improved!Attachment filtering
The new Format Recogniser feature can filter attachments – using information about file type, name and message size. This helps businesses to enforce their email usage policy and can help to address corporate liability issues that can arise when users try to distribute illegal music or video files via the corporate email system.

Improved!Global Blacklists and Whitelists
In addition to creating corporate blacklists or whitelists, administrators can manage ‘allowed’ or ‘denied’ senders email – using IPv4 and IPv6, wildcards and regular expressions.

New!Personal Blacklists and Whitelists
Users also can create their own blacklists and whitelists.

New!Backup and personal backup with flexible search
Blocked email is quarantined in a backup system. If the system uses Microsoft Active Directory or OpenLDAP, individual users can access their personal backup via the web so they’re less likely to need to call your helpdesk.

Improved!Integration with most popular MTAs (Postfix, Sendmail, Exim, qmail and CommunigatePro)
Kaspersky Security for Linux Mail Server lets you select the method of integration, depending on your choice of Mail Transfer Agent (MTA) – so you can integrate as a filter or using a Milter API.

Improved!Antivirus command line file scanner
The Kaspersky Anti-Virus On-Demand Scanner can be used for on-demand virus checking of objects – which can include directories, regular files and devices such as hard drives, flash drives and DVD-ROMs.

New!Amavisd-new
Kaspersky Security for Linux Mail Server supports integration with Linux mail systems using the high-performance AMaViS interface.

Improved!Monitoring and Reporting features

  • SNMP (Simple Network Management Protocol) support – any type of event can be monitored using SNMP events and traps
  • A new dashboard gives an at-a-glance view of status and monitoring
  • Detailed, flexible reporting in PDF format – for customisable reports that help in the monitoring and analysis of security and policies
  • Notification system – informs administrators and document owners about policy violation incidents
  • Detailed logs – on all product actions, to help in identifying problems

Improved!Easy to deploy, maintain and manage

  • System administrators can run manual updates or set the rules for fully automatic updates of antivirus, anti-spam and ZetaShield
  • Integration with Active Directory and OpenLDAP
  • Rich email traffic management rules – administrators can create rules according to corporate security policies
  • IPv6 support
  • Scalable architecture – the entire system can be easily migrated from a test server to a production environment

Benefits overview

Enhanced spam detection with fewer ‘false positives’
Kaspersky Lab’s latest technologies offer improved spam detection – to ensure that even fewer spam messages get through to your email system.

In addition, Kaspersky’s latest solution achieves a lower rate of false positives than our previous products – so your email system benefits from a high level of protection, without the inconvenience of significant numbers of legitimate emails being quarantined.

  • A recent Kaspersky study found that 43% of all spam emails in a new spam attack are distributed within the first 10 minutes. Kaspersky Security for Linux Mail Server incorporates Enforced Anti-Spam Update Service – that is designed to reduce the ‘window of exposure’ to less than one minute so new spam attacks are less likely to get through to systems that are protected by Kaspersky.
  • Kaspersky Security for Linux Mail Server includes integration with Kaspersky Security Network (KSN) – to access Kaspersky’s cloud-based database and obtain real-time information about new spam.
  • Kaspersky’s cloud-based Reputation Filtering technology uses sophisticated content-analysis tools to identify possible spam and also employs cloud-assisted capabilities to ‘compare notes with other users’. As a result, Kaspersky Security for Linux Mail Server processes messages with minimal latency, while also reducing the number of false positives and increasing the overall detection rate.

Enhanced anti-malware and zero-hour detection
Kaspersky’s latest antivirus engine delivers faster scanning and a higher detection rate – for more rapid, accurate detection of malicious email attachments. In addition, our new ZetaShield (Zero-Day Exploit and Targeted Attack Shield) is designed to identify malware within targeted attacks. The combination of Kaspersky’s antivirus engine and ZetaShield significantly boosts the malware detection rate – to help deliver an even higher level of protection for your business.

High throughput and high performance
All anti-malware and anti-spam engines add some overhead to a system. However, Kaspersky Security for Linux Mail Server has been designed to deliver high throughput – without significantly affecting system performance.

Flexible and easy to run and monitor
Kaspersky Security for Linux Mail Server has been designed to combine flexibility, ease of deployment and simplified management.

  • In addition to powerful email traffic rules and support for OpenLDAP and Active Directory, Kaspersky Security for Linux Mail Server also allows users to set up personal blacklists and whitelists – and also manage their own quarantined items. This empowers users and helps to reduce the number of calls to your helpdesk.
  • Administrators can choose to integrate Kaspersky Security for Linux Mail Server’s reporting and monitoring facilities into their organisation’s existing monitoring system (SNMP), or administrators can use Kaspersky’s new, web-based management console – which includes a dashboard that provides vital system statistics, at a glance.

Easy to integrate
Kaspersky Security for Linux Mail Server can be integrated with popular Linux-based Mail Transfer Agents (MTAs) – including Postfix, Sendmail, Exim, qmail and CommuniGate Pro – and can also be integrated with Linux-based mail systems using AMaViS. In addition, Kaspersky Security for Linux Mail Server supports IPv6.
