Network Traffic Interceptor

Only Available With VSTK Enterprise

The Network Traffic Interceptor (NTI) is a new concept in virus scanning network traffic. Instead of using proxies like other products, NTI actually implements an antivirus firewall in the computer itself. This is a new standard in virus scanning because it intercepts any potential threat prior to it's access to user application memory.

80% of all attacks originate inside the LAN. A single point-of-control firewall can only stop attacks from the outside LAN, and if a large number of people attempt to use this centralized firewall, the network could suffer bandwidth problems. NTI implements a firewall for antivirus purposes on every workstation. By locating the most process- and bandwidth-intensive part of the firewall on the local system, there is no aggregate problem, and since NTI intercepts viruses at the IP packet layer, they can be analyzed prior to reaching an application where they can potentially execute - once a virus is at the application layer the system is threatened. This is especially true of email and web browsers with extensions such as Java.

NTI comes pre-configured to scan all ftp file transfers, http downloads, SSL secure sockets layer, https downloads, pop3 email, smtp email and SMIME email attachments. SSL encryption is used for all encrypted web page transactions (https), and is the backbone of e-commerce. NTI intercepts all encrypted SSL traffic prior to user access, then performs real time cracking and scanning of the SSL encrypted connection. If the data contains viruses, then the connection is broken and the user is sent a message as to the nature of the problem - the virus never enters the system application layer.

NTI also intercepts and virus scans all SMIME encrypted email messages and attachments. It does this by reading the SMIME decryption keys from the Netscape Browser SMIME key database, and uses these keys to decrypt the message for scanning. If the message or an included attachment is infected with a virus, then the message is blocked prior to entering the system application layer.
