24 x 7 Infrastructure Attack Protection
As business become increasingly dependent on computer
technologies and Internet-based communication, significant
threats to the enterprise come in the form of:
- Denial-of-service attacks
- Dictionary harvest attacks
- Mail bombs
- Email flooding and other attacks
These are all designed to interrupt service or collect
corporate or personal email addresses. Propagating faster
than ever, these new attacks are causing greater damage than
their predecessors.
Securing your infrastructure is critical. Most people
today look to server and desktop solutions for security.
Without an upfront layer of protection these viruses, worms
and other malicious code are still a serious threat because
most hackers and junk-email vendors prey on open and
accessible Internet (SMTP) gateways.
Many enterprises have open gateways because their mail
exchange (MX) record routes, including primary IP addresses
and backup or failover servers, are publicly available.
Hackers leverage this information to understand IP
address ranges and server locations, and to connect directly
to enterprise email servers.
Our service eliminates this possibility with mxSECURE™
- a key feature that removes the threat of network probes
and completely shields your network from this vulnerability
and attack. By pointing your MX record to mxSECURE™,
its real-time filtering process:

How does mxSENTRY prevent Directory Harvest Attacks
mxSENTRY Attack Protection can defend your business network
against directory harvest attacks (DHAs), which bombard your
email servers with messages by using common name pairs or
email address patterns, or uses "brute force" to run through
alphanumeric combinations to identify valid addresses. Our
solution blocks DHAs at the network perimeter to prevent
spammers from gaining information about the validity of
random email addresses used to target businesses for future
attacks.
How does mxSENTRY protected against Denial of Service
attacks (DOS)
Denial of service (DOS) or Distributed Denial of service (DDOS)
attacks are hard to detect because while they are designed
to elude detection by masquerading as legitimate
transactions. The intent of the attacker is to launch them
on a widespread scale to overwhelm unprotected networks.
When mxSENTRY detects the excessive SMTP "chatter" like
those associated with DoS attacks, it limits the connections
it will allow from the attacking IP address, throttling back
the traffic and thereby mitigating the attack.
