SonicOS 4.0 Enhanced
SonicWall’s latest firmware release, SonicOS 4.0 Enhanced, provides advanced features and configuration flexibility for the PRO series appliances.
SonicOS 4.0 Enhanced Supported Platforms
PRO 5060, PRO 4100, PRO 4060, PRO 3060, PRO 2040 SonicOS 4.0 Enhanced Feature Highlights: - Application Firewall
Application firewall is a set of application-specific policies that gives you granular control over network traffic on the level of users, e-mail users, schedules, and IP-subnets. The primary functionality of this application layer access control feature is to regulate Web browsing, file transfer, e-mail, and e-mail attachments. Using the digital rights management component of application firewall, administrators have the ability to scan files and documents for content and keywords. Application firewall allows you to restrict file transfers of certain file names, file types, e-mail attachments, attachment types, e-mail with certain subjects, and e-mail or attachments with certain keywords or byte patterns. - Stateful Failover with Statesync HF
Stateful Failover is a high availability feature that dramatically improves network reliability by ensuring uninterrupted operation during hardware or software failures. When Stateful Hardware Failover is enabled between two SonicWALL appliances, the primary appliance actively communicates with the backup to update most network connection information. As a result, the backup appliance is always prepared to take over the active connections seamlessly with almost zero impact to networked users. - Single Sign-On
Single Sign-On (SSO) is a transparent user authentication mechanism that provides privileged access to multiple network resources with a single workstation login. - Inbound Load Balancing
Allows administrators to configure policies that will allow inbound load balancing to happen for similar network resources. The SonicWALL can support Round Robin, Random Distribution, Sticky IP, Block Remap and Symmetrical Remap load balancing algorithms. - HTTPS Content Filtering
This feature allows the SonicWALL to intercept and inspect IP based HTTPS sessions using the Content Filtering Service (CFS) to prevent network users from accessing HTTP proxy sites. - SSL Control
SSL Control provides administrators visibility into the handshake of SSL sessions and a method for constructing policies to control the establishment of SSL connections. - Services Dashboard
Services Dashboard provides a visible representation of the current global and applicant count of blocked network threats when using the SonicWALL Gateway Anti-Virus, Anti-Spyware and Intrusion Prevention Service. - Packet Capture
Packet capture is a mechanism that allows administrators to capture and examine the contents of individual data packets that traverse SonicWALL firewall appliances. This information aids administrators in troubleshooting, diagnostics and general network activity, decreasing the time it take to investigate potential issues. - Virtual Access Points
Virtual Access Points enables SonicPoints to advertise up to eight SSIDs and allows each to be associated with a Security Zone. - Wireless IDS rouge detection
Wireless IDS Rogue Detection allows you to configure a set of authorized access points, defined by address object groups. If contact is attempted from an unauthorized access point, SonicOS generates an alert. - TCP Conformance
Added support for the TCP Window Scale option as defined in RFC 1323. - DHCP Server Persistence
DHCP Server Persistence is a solution where DHCP leases are saved in the flash memory of an appliance. Whereas in the case of an appliance reboot, the DHCP clients will receive the same lease before reboot. - DHCP options
Allows vendor specific DHCP options to be used in conjunction with DHCP leases - Diagnostic page tool tips
Incorporates self-documenting mouse-over descriptions for diagnostic controls in the graphical user interface. - MS-CHAP-V2 Support
Added support for MS-CHAP-V2 for L2TP over IPsec remote access connections. - Multiple SSH management sessions
Added support for multiple SSH management sessions. - Read-only administration login
Allows read only access to the SonicWALL management interface.
