Security > Safeguard Engine
D-Link's Safeguard Engine is a robust and innovative technology that automatically throttles the impact of
packet flooding into the switch's CPU. This function helps protect the Web-Smart Switch from being
interrupted by malicious viruses or worm attacks. This option is enabled by default.
Security > Port Security
Port Security is a security feature that prevents unauthorized computers (with source MAC addresses)
unknown to the Switch prior to stopping auto-learning processing from gaining access to the network.
A given ports' (or a range of ports') dynamic MAC address learning can be stopped such that the current
source MAC addresses entered into the MAC address forwarding table cannot be changed once the port is
enabled. Using the drop-down menu, change Admin State to Enabled, and then click Apply to confirm the
setting.
Security > 802.1X > 802.1X Settings
Network switches provide easy and open access to resources by simply attaching a client PC. Unfortunately
this automatic configuration also allows unauthorized personnel to easily intrude and possibly gain access to
sensitive data.
IEEE-802.1X provides a security standard for network access control, especially in Wi-Fi wireless networks.
802.1X holds a network port disconnected until authentication is completed. The switch uses Extensible
