  • TACACS+ Authentication: Employs the TACACS+ protocol for user authentication and authorization.

Network Routing

• Static Route Precedence: Static routes take precedence over VPN traffic by default.
• TOS Routing: TOS (Type of Service) routing is used to prioritize traffic based on its importance as it exits the firewall.
• Advanced Routing Enabled by Default: Advanced routing features are enabled by default in SonicWALL firewalls.
• Static Route Variables: The following variables are used to configure static routes to forward traffic:
  • Destination Network: The specific IP address range to which traffic is forwarded.
  • Next Hop: The IP address of the next device in the routing path.
  • Interface: The outbound interface on the SonicWALL firewall.
  • Metric: A numerical value assigned to the route to determine its priority.
• Supported Advanced Routing Protocols: The SonicWALL firewall supports the following protocols for advanced routing:
  • RIP: Routing Information Protocol
  • OSPF: Open Shortest Path First
  • ISIS: Intermediate System to Intermediate System
  • BGP: Border Gateway Protocol

Firewall Logging and Event Management

• Inbound Connection Logging Best Practice: It is a general practice to log all inbound connections for security monitoring.
• Event Priority and Logging Level: If the event priority level is lower than the logging level, the events will be filtered out from the event logs..
• Error Logging: If the logging level filter is set to "error," only error messages will be displayed in the event logs.
• Log Types and Their Contents:
  • Firewall Logs: Capture events related to firewall activity, including connection attempts, rule actions, and security incidents.
  • VPN Logs: Record VPN connections, disconnections, and tunnel status changes.
