What is a Zone?
A Zone is a logical grouping of one or more interfaces and/or VLANs designed to make
management, such as the definition and application of Access Rules, a simpler and more intuitive
process than following strict physical interface scheme. Zone-based security is a powerful and
flexible method of managing both internal and external network segments, allowing the
administrator to separate and protect critical internal network resources from unapproved access
or attack.
A network security zone is simply a logical method of grouping one or more interfaces with friendly,
user-configurable names, and applying security rules as traffic passes from one zone to another
zone. Network security zones provide an additional, more flexible, layer of security for the firewall.
With the zone-based security, the administrator can group similar interfaces and apply the same
policies to them, instead of having to write the same policy for each interface.
Benefits
The extensible signature language used in SonicWALL’s Deep Packet Inspection engine also
provides proactive defense against newly discovered application and protocol vulnerabilities.
SonicWALL IPS offloads the costly and time-consuming burden of maintaining and updating
signatures for new hacker attacks through SonicWALL’s industry-leading Distributed Enforcement
Architecture (DEA). Signature granularity allows SonicWALL IPS to detect and prevent attacks
based on a global, attack group, or per-signature basis to provide maximum flexibility and control
false positives.
Alternatively, SonicWALL Global Management System (SonicWALL GMS) provides global
management capabilities that enabled administrators to manage SonicWALL IPS across multiple
SonicWALL security appliances from a central location. SonicWALL GMS and SonicWALL
ViewPoint solutions allow administrators to create detailed reports based on attack source,
destination and type of intrusion, such as “Top Intrusions,” “Destinations Over Time” and “Intrusions
Over Time.”

and SonicWALL ViewPoint.
Note Refer to the SonicWALL Gateway Anti-Virus Administrator’s Guide for information
you need to successfully activate, configure, and administer SonicWALL Gateway
Anti-Virus on a SonicWALL security appliance, located on the SonicWALL Web site:
