Pattern Match Group Menu
When a virus or other attack contains multiple patterns or strings, it is useful to combine them into one group and give the group a name that is easy to remember. When a pattern group is applied to a deny filter, Alteon matches any of the strings or patterns within that group before denying and dropping the packet. Up to five (5) patterns can be combined into a single pattern group. Configure the binary or ASCII pattern strings, group them into a pattern group, name the pattern group, and then apply the group to a filter.
The filtering commands enable the administrator to define groups of patterns and place them into groups. By applying the patterns and groups to a deny filter, the packet content can be detected and thus denied access to the network.
Alteon supports up to 1024 pattern groups.
Note: The pattern group matching feature is available only if you have purchased and enabled the Advanced Denial of Service Protection software key.
