Security Policy Settings

The following sections describe the Security Policy settings for Group VPN, IKE using Pre-shared Secret, and Manual Key.

Security Policy Settings for Group VPN

•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. 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).

•Phase 1 Encryption/Authentication - select an encryption method from the Encryption/Authen- tication for the VPN tunnel. If you select IKE using Pre-Shared Secret for your SA, you can select from one of eight encryption methods:

DES & MD5

AES-128

& MD5*

DES & SHA1

AES-128

& SHA1*

3DES & MD5

AES-256

& MD5*

3DES & SHA1

AES-256

& SHA1*

*AES support is available only on the PRO 230, PRO 330 and GX series.

These are listed in order from least secure to most secure. If network speed is preferred, then select DES & MD5. If network security is preferred, select 3DES & SHA1. To compromise between network speed and network security, select DES & SHA1. AES (Advanced Encryption Standard) is an encryption method for securing sensitive but unclassified material by U.S. Government agencies.

These are listed in order from least secure to most secure. If network speed is preferred, then select DES & MD5. If network security is preferred, select 3DES & SHA1. To compromise between network speed and network security, select DES & SHA1.

•Phase 2 Encryption/Authentication - Phase 2 Encryption/Authentication is different for the Group VPN SA. The VPN Client does not support ARCFour encryption methods, and you cannot disable authentication in the VPN client. The following encryption methods are available for Group VPN and are listed in order from most secure to least secure:

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.
