Fast user switching in Windows is based on Remote Desktop Services technology. [3] In Windows XP, GINA which is a component of Winlogon, and with which fast user switching interacts, can be programmatically called to automate a fast user switch. [4] A PowerToy known as Super fast user switcher was offered in 2002 by
In computer networking, a media access control attack or MAC flooding is a technique employed to compromise the security of network switches.The attack works by forcing legitimate MAC table contents out of the switch and forcing a unicast flooding behavior potentially sending sensitive information to portions of the network where it is not normally intended to go.
MACFF is described in RFC 4562, MAC-Forced Forwarding: A Method for Subscriber Separation on an Ethernet Access Network. Allied Telesis switches implement MACFF [1] using DHCP snooping to maintain a database of the hosts that appear on each switch port. When a host tries to access the network through a switch port, DHCP snooping checks the host ...
The Individual Address Block (IAB) is an inactive registry which has been replaced by the MA-S (MAC address block, small), previously named OUI-36, and has no overlaps in addresses with the IAB [6] registry product as of January 1, 2014. The IAB uses an OUI from the MA-L (MAC address block, large) registry, previously called the OUI registry.
[3] [7] [8] Fast User Switching allows users to switch between user accounts on the local computer without quitting software and logging out. Fast User Switching is part of Winlogon and uses RDS to accomplish its switching feature. [9] [10] Third-party developers have also created client software for RDS. For example, rdesktop supports Unix ...
Less common is the artificial flooding of address tables in a MAC flooding attack. Another common cause is a host with an ARP cache timeout longer than the timeout of the forwarding information base (FIB) in a switch—the switch forgets which port connects to the target before the host forgets the MAC address of the target. [2]
The switch then forwards the frame to the interface found in the CAM based on the frame's destination MAC address. If the destination address is unknown the switch sends the frame out on all interfaces (except the ingress interface). This behavior is called unicast flooding.
A forwarding information base (FIB), also known as a forwarding table or MAC table, is most commonly used in network bridging, routing, and similar functions to find the proper output network interface controller to which the input interface should forward a packet. It is a dynamic table that maps MAC addresses to ports.
