Executive Summary

The ISG series Integrated Security Gateways are firewall/VPN-based systems that deliver security features such as Intrusion Prevention System (IPS), Antispam, Web Filtering, and Internet Content Adaptation Protocol (ICAP) antivirus redirection support. The advanced system is further expandable with optionally integrated Intrusion Detection and Prevention (IDP) or as a General Packet Radio Service (GPRS) firewall/VPN for mobile network service provider environments. The widespread use of mobile computing and telecommuting has increased the need for effective protection of computing platforms. Traditional schemes that involve strengthening the security of individual systems or the use of firewalls at network entry points have difficulty accommodating the special requirements of remote and mobile users.
