  6. Security in most common network architecture Security is applied to the core switch at the backbone Impossible to control network traffics Result: Bad performance of network and endangerment of all users in the network as the switch is unable to control LAN access of illegitimate users from accessing the network without authentication, exposing them to risks such as: DoS attack Virus infection Worm, etc Security in D-Link networks Security is applied to the endpoint switch Effective prevention of illegal users from accessing the network as all users attempting to access the network will be checked for its integrity and will require to be authenticated by the switch according to selected method Result: Risk of security threat from illegitimate user is substantially minimized, and firm network security is actualized.

  8. Virtual stacking with SIM (Single IP Management) LAN Endpoint User authentication with Web-based Authentication User authentication with MAC-based Authentication 802.1X user authentication Security Methods for a Unified Endpoint Security: User Certification • 802.1X authentication • Web-based authentication • MAC authentication • Combined authentication of all 3 at Endpoint Switch Click

  9. Illegal user Security Methods for a Unified Endpoint Security: Client’s Quarantine 802.1X Network Access Protection (NAP) Office VLAN Guest VLAN Office server Windows2008 NAP server • PC quarantine, for clients that do not meet health standard defined by the server This is done in collaboration with NAP (Network Access Protection) quarantine function, supported by Microsoft 2008 server and 802.1X function supported by D-Link xStack Switch. • Types of client supported is limited to Windows XP/Vista only • NAP Policy Enforcement checks the health status (example: firewall setting circumstance, update circumstance and Windows update setting circumstance of anti virus) of a client when it requests to access the network • Only clients that meet the health standard defined by the server are allowed to access the network, otherwise it will be directed to a restricted network (i.e. Guest VLAN) Office LAN DGS-3200-10 LAN Endpoint L2 Switch NAP not-corresponding Endpoint MAC-based Authentication Healthy XP Client NAP Quarantine checking passed Healthy XP Client NAP Quarantine checking passed Unhealthy Vista Client NAP Quarantine checking failed

VLAN Security Methods for a Unified Endpoint Security: Access Control (1) Access control to the network is possible if using VLAN-ID which is allotted on the basis of user authentication. Access Control with Dynamic VLAN Office LAN DGS-3627 DGS-3200-10 DGS-3200-10 LAN Endpoint Even the client moves to another location, the VLAN that the client belongs to is still the same Employee transferred to Finance Div Click

  11. Virus infected client Security Methods for a Unified Endpoint Security: Access Control (2) ZoneDefense technology: A collaboration between D-Link UTM/ Firewall and D-Link xStack Switch • With real time anti-virus scanning and IPS of the UTM firewall, harmful traffics which come from internal users in the LAN can be detected. • In ZoneDefense technology, D-Link UTM/ Firewall cooperates with the switch where all clients are connected to. When it detects a malicious traffic, such as virus, worm, etc, in the network, it will shutdown the port where the virus is coming from, thus, increasing the security level. Firewall (DFL series) ① Inspection of abnormal traffic Inspecting any illegitimate communication by viruses using anti-virus engine/ IPS ② Shutdown of Switch Port When the firewall detects illegality at a port, it will inform the switch, and the switch will shutdown the port where the PC is transmitting the illegality Office LAN DGS-3200-10 DGS-3200-10 DGS-3200-10 DGS-3200-10 Click
