25 Chapter 3 VPN A virtual private network (VPN) is a private network that interconnects remote (and often geographically separate) networks through primarily public communication infrastructures such as the Internet. VPNs provide security through tunneling protocols and security procedures such as encryption. For example, a VPN could be used to securely connect the branch offices of an organization to a head office network through the public Internet. IPsec L2TP PPTP GRE Introduction to IPsec Internet Protocol Security (IPsec) is a protocol suite for securing Internet Protocol (IP) communications by authenticating and encrypting each IP packet of a communication session.

58 Chapter 6 IDS cooperation 6.1 Introduction Firewall device added up with IDS cooperation function in order to cooperate with IDS device. IDS device can detect network traffic if attacks exist and sent SNMIP Trap information to the firewall device with blocking information, including source IP address and destination IP address of the packets. When IDS cooperation function enabled, the firewall receives SNMP Trap information and generates blocked entry for the follow-up traffic. 6.2 IDS Integration Display IDS cooperation log To enter the display IDS cooperation log page, you choose Service > IDS integration > Display IDS cooperation log, as shown in Figure6-1.

59 Chapter 7 High Availability 7.1 VRRP High availability module provides the following features: VRRP Hot standby Interface synchronization group To enter the VRRP page, you choose Probe module > High availability > VRRP, as shown in Figure7-1. Figure7-1 High availability Introduction to VRRP Group During data communication process, software and hardware error may result network disconnection, causing data transmission failure. To avoid data communication disconnected, DPtech Probe service board module has provides Virtual Router Redundancy Protocol (VRRP) technology using backup solution when communication line or device failure, so that it ensure data communication smoothly and enhance network robustness and availability. Enhancing local network and outside network connection availability, VRRP is fit for the local area network which support multicast and broadcast (such as Ethernet). Through many devices forming a backup group, they have an exit gateway for the local network and they are all transparent inside the local network. In the back up group, if an FW device failure, it will be substituted by other device. So that the local host can still work without any modification, greatly enhance network communication availability. To enter the VRRP page, you choose Probe module > High availability > VRRP, as shown in Figure
