The Security Services Settings section provides the following options for fine-tuning SonicWall security services:
•
|
Security Services Settings - This drop-down menu specifies whether SonicWall security services are applied to maximize security or to maximize performance:
|
•
|
Maximum Security (Recommended) - Inspect all content with any threat probability (high/medium/low). For additional performance capacity in this maximum security setting, utilize SonicOS Clustering.
|
•
|
Performance Optimized - Inspect all content with a high or medium threat probability. Consider this performance optimized security setting for bandwidth or CPU intensive gateway deployments or utilize SonicOS DPI Clustering.
|
The Maximum Security setting provides maximum protection. The Performance Optimized setting utilizes knowledge of the currently known threats to provide high protection against active threats in the threat landscape.
•
|
Reduce Anti-Virus traffic for ISDN connections - Select this feature to enable the SonicWall Anti-Virus to check only once a day (every 24 hours) for updates and reduce the frequency of outbound traffic for users who do not have an “always on” Internet connection.
|
•
|
Drop all packets while IPS, GAV and Anti-Spyware database is reloading - Select this option to instruct the SonicWall security appliance to drop all packets whenever the IPS, GAV, and Anti-Sypware database is updating.
|
•
|
HTTP Clientless Notification Timeout for Gateway AntiVirus and AntiSpyware - Set the timeout duration, in seconds, after which the SonicWall security appliance notifies users when GAV or Anti-Spyware detects an incoming threat from an HTTP server. The default timeout is one day (86400 seconds), the minimum time is 10 seconds, and the maximum time is 2147483647 seconds .
