    ETTING TARTED WITH THE The DFL-M510 is a transparent network device. To ensure there is no disruption to your network, it can be installed in In-Line mode with a hardware bypass function enabled. The hardware bypass ensures that if the DFL-M510 crashes, experiences a power out or some other problem, your net- work is still up and running.

    Click the Parameter tab. The following screen appears. This tab defines management parameters. PERATION The DFL-M510 only protects and monitors your net- work when set to In-Line mode. The other modes offer limited monitoring and are used for integrating the DFL-M510 smoothly with your network.

  • Page 43

    DFL-M510 will detect all events by inspecting all packets. In this mode, the DFL-M510 will log all events, but will not take any countermeasure (reset, drop actions). It is suggested to monitor net- work traffic in this mode before setting In-Line mode, in order to fine tune your security policy and network performance.

    That is, the network mask contains only two pairs: the leading 1s, and the following 0s. NOTE DMZ Bypass prevents the DFL-M510 from causing a bottleneck in your intranet.

    Information Security Gateway A VLAN (Virtual LAN) is a group of devices on one or more LANs that are configured (using management software) so that they can communicate as if they were attached to the same wire, when in fact they are located on a number of different LAN segments. Because VLANs are based on logical instead of physical connections, they are extremely flexible.

    HAPTER ROUPS A host is a client computer with a network interface. A group is a set of hosts. The DFL-M510 learns host information from packets passing through the device. Host information includes the MAC address, IP address and VLAN address. In order to manage the host internet access, we can lock a host with a MAC address and/or an IP address.

    HAPTER OLICY Policy is the most important information in the DFL-M510 Management System. A policy can consist of thousands of patterns. Each pattern defines how to detect an application, how to respond when an application is detected, what to block, and when to block. You can view and modify the settings, including applying scope, acting schedule, actions and information such as category, and constraints.

  • Page 66: Running The Template Wizard

    DFL-M510 After the policy database is published and fetched, it is uploaded to the DFL-M510.
