How TupSight intercepts data of computer communications and enforces employee Internet policies?
TupSight boasts the broadest operation spectrum among the EIM (Employee Internet Management) products commercially available. 1) Gateway Mode: This is the default operation mode of TupSight. The NAT gateway technology embedded in the software enables a reliable LAN infrastructure/hardware-independent web monitoring and control at the Internet doorsteps. 2) Promiscuous Mode: In the early days of computer networking, the sharing nature of communication channels on a local computer network made packet sniffing possible, by which an intruding hacker picked up passwords and other useful information, and a network administrator diagnosed and trouble-shooted network traffic (see http://www.faqs.org/faqs/computer-security/sniffers/).
