  Linux-based Virtual Private Network (VPN)
The Virtual Private Networking / Firewall solution is designed to maximize network security without compromising network performance. It uses data encryption, user authentication and the Internet to securely connect telecommuters, remote offices, customers or suppliers to the corporate office while avoiding the cost of private leased lines or dial up charges. A browser-based interface eases VPN configuration and management. VPN functionality is based on IPSec and PPTP protocols and uses 3DES 128- bit encryption to ensure that information remains private. The Firewall security utilizes Stateful Packet Inspection and provides optional anti-virus protection.

Key characteristics of the VPN

• Protection from unauthorized access
• Ensure data/information integrity
• Ensure confidentiality

Key characteristics of the Firewall

• Stateful packet inspection
• Conceal internal network structure through Masquerading, SNAT, DNAT
• Application layer security using HTTP, DNS, SMTP, SOCKS proxies
• Alerting the administrator of relevant network events
