Firewall and Security:

  • Secure Boot
  • Firewall Security:
    • Inclusion Policy - Access Control based upon White List IP addresses, MAC address and IP Domain
    • Exclusion Policy -Access Control based on Black List
  • Continuous monitoring of the TLS connection to nullify MitM attacks
  • Resistance to Denial of Service (DoS) Attack
  • Encrypted Firmware Updates
  • Non-volatile Access Log with capability to "fingerprint" all successful and failed log-in attempts and keep a log of the IP and MAC addresses of all successful and failed logins / login attempts
  • SNMP trap generation, along with LED and external alarm indication
  • Password Protection with password strength monitor
  • RADIUS Password Authentication
  • SSH (Secure Access Control) with encrypted Password Protection

Firewall Resilience:

  • May be used in conjunction with VCL-2478; or VCL-2454, Ethernet Failover Switches to provide 1:N Firewall Redundancy and Automatic Failover in the event of equipment failure; or in the event of hostile intrusion attempts.
  • Valiant’s Enigmätron-C uses complex algorithms to automatically detect attempts to break it and may be used in conjunction with VCL-2478; or VCL-2454, Ethernet Failover Switches to very effectively to repel and frustrate all such hostile intrusion attempts, including DoS (Denial of Service) attacks.
