-Strong Encrypt and Authenticate (ESP 3DES HMAC SHA1) - uses 168-bit 3DES encryption and HMAC SHA1 authentication. 3DES is an extremely secure encryption method, and HMAC SHA1 is used to verify integrity. This method significantly impacts the data throughput of the SonicWALL.

-Strong Encrypt and Authenticate (ESP 3DES HMAC MD5) - uses 168-bit 3DES encryption and HMAC MD5 authentication. 3DES is an extremely secure encryption method, and HMAC MD5 is used to verify integrity. This method significantly impacts the data throughput of the SonicWALL.

-Strong Encrypt and Authenticate (ESP DES HMAC SHA1) - uses 56-bit DES encryption and HMAC SHA1 authentication.

-Strong Encrypt and Authenticate (ESP DES HMAC MD5) - uses 56-bit DES encryption and HMAC MD5 authentication. This method impacts the data throughput of VPN communications. SonicWALL VPN client supports this method.

-Strong Encrypt and Authenticate (ESP AES-128 HMAC MD5) - uses 128-bit AES encryption and HMAC MD5 authentication.

-Strong Encrypt and Authenticate (ESP AES-128 HMAC SHA1) - uses 128-bit AES encryption and HMAC SHA1 authentication.

•Shared Secret - an alphanumeric key is automatically generated as the Shared Secret. The Shared Secret is not exported with the VPN Client Configuration File. The Shared Secret must be distributed by the SonicWALL administrator.

Security Policy Settings for IKE using Pre-shared Secret

•Exchange - select Main Mode or Aggressive Mode. Main Mode requires six one-way messages between the peers and Aggressive Mode requires only three one-way messages making Aggressive Mode a little faster when establishing the connection. Selecting Aggressive Mode forces the SonicWALL appliance to use Aggressive Mode to establish the VPN tunnel even if the SonicWALL has a static IP address. Aggressive Mode is useful when the SonicWALL is located behind another NAT device.

•Phase 1 DH Group - Diffie-Hellman (DH) key exchange (a key agreement protocol) is used during phase 1 of the authentication process to establish pre-shared keys. Groups 1, 2, 5 use Modular- Exponential with different prime lengths as listed below:

Group Descriptor

Prime Size

(bits)

 

 

 

 

 

Group 1

768

 

 

Group 2

1024

 

 

Group 5

1536

 

 

If network speed is preferred, select Group 1. If network security is preferred, select Group 5. To compromise between network speed and network security, select Group 2.

•SA Life time (secs) - allows you to configure the length of time a VPN tunnel is active. The default value is 28800 seconds (eight hours). You can configure up to 2,500,000 seconds (28.9 days).

Internet Security Appliances specifications

SonicWALL Internet Security Appliances are pivotal solutions aimed at safeguarding networks from an ever-evolving array of cyber threats. Designed for small to medium-sized businesses, as well as enterprises, these appliances deliver robust security and high-performance capabilities.

One of the main features of SonicWALL Internet Security Appliances is their Unified Threat Management (UTM) functionality. This integrated approach allows organizations to manage multiple security measures, including firewall protection, intrusion prevention systems (IPS), and antivirus capabilities, within a single device. This consolidation simplifies security management and reduces the risk of vulnerabilities from disparate systems.

Another significant technology found in these appliances is Application Control. This feature enables administrators to monitor and regulate the applications and services used within their networks, ensuring that bandwidth is allocated efficiently, and potentially harmful applications are blocked. Coupled with Content Filtering, SonicWALL offers granular policies to restrict access to inappropriate or non-work-related content, enhancing overall productivity while maintaining security.

SonicWALL appliances also utilize advanced cybersecurity technologies like SonicWall Capture Threat Assessment and Capture Advanced Threat Protection. These solutions leverage artificial intelligence to identify and remove sophisticated malware and ransomware threats before they infiltrate the network. This proactive approach ensures that only safe email and web traffic is allowed through, providing comprehensive protection against advanced persistent threats.

Moreover, SonicWALL’s Global Management System (GMS) enables centralized control over multiple security devices, making it easy for IT teams to maintain a consistent security posture across various locations. This capability is especially beneficial for organizations with distributed networks, as it provides real-time visibility into network activity and security incidents.

The appliances are also designed with scalability in mind. Whether an organization grows or needs to adjust its security policies, SonicWALL appliances can be updated, expanded, or modified without significant disruptions. This flexibility makes them a long-term investment for any business focused on network security.

In addition, SonicWALL's user-friendly interface simplifies the deployment and management processes. With intuitive dashboards and reporting tools, administrators can easily track security events, analyze network traffic patterns, and respond swiftly to potential threats.

In summary, SonicWALL Internet Security Appliances combine essential features like Unified Threat Management, Application Control, and advanced threat protection technologies into a cohesive security solution. Their scalability, centralized management capabilities, and user-friendly interfaces make them an excellent choice for businesses aiming to strengthen their cyber defenses in a complex digital landscape.
