CAMELOT Security

Version
2005
CAMELOT Security 2005 is a server side based spam
filtering solution for MS Windows platforms. Incoming
messages run through a chain of different application
layers inside a multi-tier protection system. Several
methods of analysis are executed by active content
processors, using artificial intelligence with self-
learning filter processes. A special SMTP gateway
verifies the identity of the sending instance and
denies all further processing as soon as an invalid
incident occurs. This prevents unauthorized access
before the message is delivered to the regular mail
system. A structured profile set, based on network and
account attributes, is used to address message
contents in consideration of different requirements.
Individual anti spam rules are executed, depending on
the related user or network location. The evaluation
of unknown content schemes takes effect by Bayesian
classification methods. Intelligent content processors
identify the appropriate category by calculating the
conditional probability of the affected content. Also
pornographic contents in images can be detected in
this way. Well known anti virus products can be
integrated to prevent virus infection. A special
interface to Norman Virus Control offers a proactive
solution to protect the system against new and unknown
viruses. Multiple messages are processed simultaneous
in a multi threaded environment. This guarantees
unrestricted email transfer, even if the system is
busy with single large messages. The usage of SQL
databases for the storage of generated pool data
provides high performance also in large messaging
environments. The message processing is server side
based and thus controlled at a centralized level. This
protects the rest of the network from dangerous
contents. Explicit boundaries between secure and
insecure areas are set in this way. This minimizes the
remaining risk, caused by weak points somewhere in the
network.
