Real-Time Scan of SMTP, POP3, HTTP, and FTP Protocols
Three of the primary types of software tools in use on the Internet are email programs,
Web browsers, and file transfer programs, delivered over SMTP/POP3, HTTP, and
FTP protocols respectively. Since these programs and protocols are the primary ways
that malware can get onto your network and computers, any security solution that
wishes to be comprehensive must address each protocol in turn. InterScan Gateway
Security Appliance meets this requirement and does so strategically—right at the
Internet gateway.
InterScan Gateway Security Appliance performs real-time scans of SMTP, POP3,
HTTP, and FTP protocols, providing protocol-specific protection whether you are
sending and receiving email, browsing the Web, or transferring files to and from FTP
sites. By conducting real-time scans of SMTP, POP3, HTTP, and FTP traffic right at
the gateway, InterScan Gateway Security Appliance halts malicious payloads before
they can enter your network.
The Web Console
Trend Micro provides easy administration and management of InterScan Gateway
Security Appliance through a Web console, accessible from any machine outfitted
with a compatible Web browser. Compatible browsers are:
• Microsoft Internet Explorer 6.x
• Mozilla Firefox 1.x
Using the Web console, you have easy access to all InterScan Gateway Security
Appliances on the network. The InterScan Gateway Security Appliance Web console
lets you configure the appliance, customize settings, and generally manage all your
security processes from one convenient interface, accessible anywhere on your local
area network (LAN)—or even remotely, from over the Internet, while providing
security from unauthorized users. See
Accessing the Web Console on page 4-3 and
Navigating the Web Console on page 4-12 for more details.
Content Filtering
Objectionable content in email is a problem for both inbound and outbound mail.
Therefore, the content filter in InterScan Gateway Security Appliance provides a
means for the administrator to evaluate and control the delivery of email based on the
