Routers

In order for a computer to operate on a network, there is a range of different components that are required. They are the bridge, router, DSL modem, switch, network interface card and Hub. A bridge is a hardware and software devices designed for bridging applications. Bridge start on the OSI Model Data Link Layer. Their function is to detect an error and control the flow on the physical link. They look for the MAC addresses for Ethernet and Token Ring to determine whether or not to forward or…

Procedural and Informational Documentation: In this lab, I try to use as much of the same password as possible even though that’s one of the worst practices from a security standpoint. In this lab, I made three VMs (PFSense Router, RHEL 7 for the monitoring server and another separate RHEL 7 for the Wiki server). The reason I made separate servers for the monitoring and the wiki is to avoid multiple disruptions of services in case of a single VM being down. The passwords for…

The SIP protocol requires the packets to be received in a timely manner. If the routers are routing packets and taking longer than normal it could completely drop the call as the protocol has timed out. This is also the same issue whit malfunctioning SIP protocol timers. The timers are in place to end calls if the connection has been…

via cables, telephone lines and satellites. (Mowery & Simcoe, 2001). The Internet’s running system is underpinned by the protocols of Transmission Control Protocol (TCP) and Internet protocol (IP). Information can be transmitted through several routers to ensure reliability and performance .The TCIP dissembles this information into smaller chunks of information known as packets, for the purpose of efficient delivery and to reduce the vulnerability of threats. (Mowery & Simcoe, 2011). The…

Introduction In every day-to-day human endeavor, people are exposed to risk in some way or the other. This happens from the time they wake up, go to work, school and come back to the same bed.

This is called the loss likelihood. For any activity that brings reward or profit, risk is one partner that cannot be treated separately.…
