SonicWALL security appliances provide automatic attack protection against well known 
exploits. The majority of these legacy attacks were identified by telltale IP or TCP/UDP 
characteristics, and recognition was limited to a set of fixed layer 3 and layer 4 values. As the 
breadth and sophistication of attacks evolved, it’s become essential to dig deeper into the 
traffic, and to develop the sort of adaptability that could keep pace with the new threats.
All SonicWALL security appliances, even those running SonicWALL IPS, continue to recognize 
these legacy port and protocol types of attacks. The current behavior on all SonicWALL security 
appliances devices is to automatically and holistically prevent these legacy attacks, meaning 
that it is not possible to disable prevention of these attacks either individually or globally.
SonicWALL security appliances now include an expanded list of attack categories that can be 
logged.
The View Style menu provides the following three log category views:
  •
All Categories - Displays both Legacy Categories and Expanded Categories.
  •
Legacy Categories - Displays log categories carried over from earlier SonicWALL log 
event categories.
  •
Expanded Categories - Displays the expanded listing of categories that includes the older 
Legacy Categories log events rearranged into the new structure.
The following table describes both the Legacy and Extended log categories.
