Advanced configuration 309 Configuring advanced parameters ■ Configuring Network Security console parameters ■ Configuring advanced parameters About parameters for clusters, nodes, and sensors Configurable parameters provide the tools for customizing the intrusion detection system to your environment at all levels. The majority of parameters can be set in both Network Security software nodes and 7100 Series appliance nodes, with a few exceptions. ■ Cluster parameter: Applies to all Network Security software nodes or 7100 Series nodes across an entire cluster. Setting QSP Port Number is set cluster-wide because it controls communication between all nodes in a cluster. It is applied first to the master node in a cluster, and then propagated throughout the cluster. ■ Node parameters: Apply to an individual Network Security software node or 7100 Series node, or a subset of nodes within a cluster. Some settings depend on the processing capacity of the node and the amount of traffic you expect it to monitor. ■ Software nodes: The Network Security software nodes include parameters that allow for variations from the default during installation, such as Setting Event Writer File, Setting Compression Command, and Setting Location of SCP Binary. These configurations are pre-determined for appliances. ■ Appliance nodes: The Setting Lock LCD Screen parameter applies exclusively to 7100 Series nodes. ■ Sensor parameters: Apply to sensor processes only, and can be applied to a single sensor or a group of sensors. About basic setup and advanced tuning Configurable parameters provide the tools for customizing the intrusion detection system to your environment. Two sets of parameters exist, for basic setup and customizing to your environment, and for advanced tuning for specialized circumstances. ■ Basic: Include the basic tools to customize Symantec Network Security to your environment. ■ Advanced: In most circumstances, advanced parameters are set with optimum defaults. For advanced users with very specialized circumstances, advanced parameters provide a way to tune the sensitivity.
