Robin, a professional hacker, targeted an organization’s network to sniff all the traffic. During this process, Robin plugged in a rough switch to an unused port in the LAN with a priority lower than any other switch in the network so that he could make it a root bridge that will later allow him to sniff all the traffic in the network. What is the attack performed by Robin in above scenario?

CISSP Devices – Bk1D5T1St3

Many types of devices exist within a system. Desktop computers, laptops, tablets, key-boards, mice, microphones, speakers, and phones are all devices that people in many organizations use every day. Networks are made up of routers, switches, hubs, servers, and cables (even if these are located at a remote location and accessed through the cloud). Similarly, archives and storage are made up of discs, tapes, or other hardware (again, even if these are located and accessed …

CISSP Network Security from Hardware Devices – Bk1D4T1St5

The practice of information security in an organization consists of proficiency with numerous infrastructure and network components that deliver prevention, detection, and response capabilities. Collaboration with other network architects and engineers will be necessary to implement and operate a defense-in-depth technical control portfolio. To understand several of the following devices, a working definitions of a few terms may be important. A broadcast domain is a logical division of a computer network, in which all nodes …

How to Access Cisco Catalyst & Switch CLI

Leave a Comment / CCNA / By

This article is explain How to Access Cisco Catalyst & Switch CLI , Cisco catalyst switches & Accessing the cisco IOS CLI. Cisco uses the concept of a command-line interface (CLI) with its router products and most of its Catalyst LAN switch products. The CLI may be a text-based interface during which the user, typically a network engineer, enters a text command and presses Enter. Pressing Enter sends the command to the switch, which tells …

LAN Switching Concepts A modern Ethernet LAN connects user devices also as servers into some switches, with the switches then connecting to every other, sometimes during a design like Figure 7-1. a part of the LAN, called a campus LAN, supports the end user population as shown on the left of the figure. user devices connect to LAN switches, which in turn connect to other switches so that a path exists to the rest of …

Learning MAC Addresses

Leave a Comment / CCNA / By

Learning MAC Addresses Thankfully, the networking staff doesn’t need to type altogether those MAC table entries. Instead, the switches do their second main function: to learn the MAC addresses and interfaces to place into its address table. With an entire MAC address table, the switch can make accurate forwarding and filtering decisions as just discussed. Switches build the address table by listening to incoming frames and examining the source MAC address within the frame. If …

Verifying and Analyzing Ethernet Switching

Leave a Comment / CCNA / By

Verifying and Analyzing Ethernet Switching A Cisco Catalyst switch comes from the factory able to switch frames. All you’ve got to do is connect the facility cable, connect the Ethernet cables, and therefore the switch starts switching incoming frames. Connect multiple switches together, and that they are able to forward frames between the switches also . and therefore the big reason behind this default behavior has to do with the default settings on the switches. Cisco Catalyst switches …
