|SonicOS Feature Summary|
Achieve deeper network security
Dell SonicWALL NSA Series firewalls are capable of providing organizations of any size with a deeper level of network security because they are designed using a scalable, multi-core hardware architecture and a patented, single-pass, low-latency, Reassembly-Free Deep Packet Inspection® (RFDPI) engine that can scan every byte of every packet while maintaining high performance. The Dell SonicWALL NSA Series goes deeper than other firewalls with an RFDPI engine that combines real-time SSL decryption and inspection, an intrusion prevention system (IPS) that features sophisticated anti-evasion technology and a network-based malware protection system that leverages the power of the cloud. Now organizations can block daily new threats as they appear.
It is estimated that organizations are blind to approximately one third of their network traffic due to SSL encryption. SSL Decryption and Inspection technology available on the Dell SonicWALL NSA Series enables the RFDPI engine to decrypt and inspect all of network traffic on every port.
Every hour new variants of malware are developed. The Dell SonicWALL NSA Series keeps you abreast of these threats with network-based malware protection that leverages a cloud database which is updated continually and currently contains more than 13 million variants of malware.
The Dell SonicWALL Intrusion Prevention Service (IPS) protects against an array of network-based application vulnerabilities and exploits. New application vulnerabilities are discovered every day making ongoing IPS updates critical in keeping protection up to date from emerging threats. Dell SonicWALL goes a step beyond traditional solutions with an intrusion prevention system that features sophisticated anti-evasion technology. It scans all network traffic for worms, Trojans, software vulnerabilities, backdoor exploits, and other types of malicious attacks. Cybercriminals often try to circumvent the IPS by using complex algorithms to evade detection. Dell NGFWs feature advanced threat protection to decode hidden attacks before they can harm your organization. By focusing on known malicious traffic, Dell SonicWALL IPS filters out false positives while increasing network reliability and performance. Designed to protect against both internal and external threats, Dell SonicWALL IPS monitors network traffic for malicious or anomalous behavior, then blocks or logs traffic based on predefined policy.
Reassembly-Free Deep Packet Inspection engine
The Dell SonicWALL Reassembly-Free Deep Packet Inspection (RFDPI) engine provides superior threat protection and application control without compromising performance. It relies on streaming traffic payload inspection to detect threats at Layers 3-7, and takes network streams through extensive and repeated normalization and decryption in order to neutralize advanced evasion techniques that seek to confuse detection engines and sneak malicious code into the network.
Once a packet undergoes the necessary pre-processing, including SSL decryption, it is analyzed against a single, proprietary memory representation of three signature databases: intrusion attacks, malware and applications. The connection state is then advanced to represent the position of the stream relative to these databases until it encounters a state of attack, or other “match” event, at which point a pre-set action is taken.
In most cases, the connection is terminated and proper logging and notification events are created. However, the engine can also be configured for inspection only or, in case of application detection, to provide Layer 7 bandwidth management services for the remainder of the application stream as soon as the application is identified.
Security and protection
The dedicated, in-house Dell SonicWALL Threat Research Team works on researching and developing countermeasures to deploy to the firewalls in the field for up-to-date protection. The team leverages more than one million sensors across the globe for malware samples, and for telemetry feedback on the latest threat information, which in turn is fed into the intrusion prevention, anti-malware and application detection capabilities.
Dell SonicWALL NGFW customers benefit from continuously updated threat protection around the clock, with new updates taking effect immediately without reboots or interruptions. The signatures resident on the appliances are designed to protect against wide classes of attacks, covering tens of thousands of individual threats with a single signature.
In addition to the countermeasures on the appliance, NSA appliances also have access to the Dell SonicWALL CloudAV Service, which extends the onboard signature intelligence with more than twelve million signatures. This CloudAV database is accessed via a proprietary, light-weight protocol by the firewall to augment the inspection done on the appliance. With Geo-IP and botnet filtering capabilities, Dell SonicWALL NGFWs are able to block traffic from dangerous domains or entire geographies in order to reduce the risk profile of the network.
Application intelligence and control
Application intelligence informs administrators of application traffic traversing their network, so they can schedule application controls based on business priority, throttle unproductive applications and block potentially dangerous applications. Real-time visualization identifies traffic anomalies as they happen, enabling immediate countermeasures against potential inbound or outbound attacks or performance bottlenecks.
Dell SonicWALL Application Traffic Analytics provide granular insight into application traffic, bandwidth utilization and security threats, as well as powerful troubleshooting and forensics capabilities. Additionally, secure Single Sign-On (SSO) capabilities ease the user experience, increase productivity and reduce support calls.
The Dell SonicWALL Global Management System (GMS®) simplifies management of application intelligence and control using an intuitive, web-based interface.
Flexible, Customizable Deployment Options:
Every Dell SonicWALL NSA appliance utilizes a breakthrough, multi-core hardware design and Reassembly-Free Deep Packet Inspection for internal and external network protection without compromising network performance. The NSA Series NGFWs combine high-speed intrusion prevention; file and content inspection; and powerful application intelligence and control with an extensive array of advanced networking and flexible configuration features. The NSA Series offers an affordable platform that is easy to deploy and manage in a wide variety of large, branch office and distributed network environments.
