I2O Solutions - HDN Network Security Solution

  1. 1. Industry’s 1st Security Switch HanDreamnet Apr 2, 2014
  2. 2. Is perimeter security adequate? 80% of IT breaches are perpetrated by internal traffic !!!! Outside Network Required  Auto detect / block  Block only harmful traffic  Cost effective solution  Easy Maintenance Well Prepared from Attack outside with IPS / Firewall No Active Protection from internal attack Backbone Layer Second damaged level from internal user attack Attack make the overall performance to be delayed. 2 Access Network (Internal) No real-time detect & protection from Attack / Hacking Very vulnerable if the attack raise from access level
  3. 3. Hacking Direct Attack Intended (Sniffing/Spoofing) HanDreamnet Solution SECURITY 3 Attack Network Attack (Flooding/DDoS) ISSUE Authentication  Provide internal user authentication  Easy management Network Resource Management  Intercept Massage or Files  Tapping Authentication(VoIP)  Network Down due to attack  Spread damage to the upper layer or peers
  4. 4. 4 Hacking IP & ARP spoofing Network trouble (Management Issue) IP Address conflicts Cable Loop Attacking DoS/DDoS/SCAN/TCP Syn flooding etc L2 Authentication Internal IP address management Current Network Threats How does your current L2/L3 switch prevent…
  5. 5. 5 HDN Switch Differentiator Active and Real Time Solutions for • DoS/DDoS Attacks • Advanced Persistent Threats • Cable Looping • Information Leakage
  6. 6. DoS/Harmful traffic from internal 6 현재 네트워크 문제점 Internet No internal security • Harmful traffic spread into internal network Effect on entire network • Internal attack effects on entire network Difficult to find out • Hard to find out where
  7. 7. DoS/Harmful traffic from internal 7 현재 네트워크 문제점 Secured internal network • No agent software required Protect entire network • Block harmful traffic only • Normal traffic can be passed Easy to find problem • Auto detection • Report function provide Internet
  8. 8. Solution for APT (Advanced Persistent Threat) 8 현재 네트워크 문제점 Blocking Point • Only blocking outbound packet Internal Network • Malware can spread internal network finding APT source • Hard to find APT source device or port of the switch Internet APT Malware Protection System
