2) List 3 Reasons Why Mac-Security/Port Security Is Important For A Business Access Security10/21/2021
Layer 2 switching (or Data Link layer switching) is the process of using devices’ MAC addresses to decide where to forward frames. In a retail store, for example, the principal security concerns are shoplifting and employee. Most security and protection systems emphasize certain hazards more than others. Security and protection system, any of various means or devices designed to guard persons and property against a broad range of hazards, including crime, fire, accidents, espionage, sabotage, subversion, and attack.Myisp.Secure Data Network System. CenturyLink filters port 25 for increased security. They break up one large collision domain into multiple smaller ones.Open the IIS 6 application Expand the server name so the SMTP server is visible: Right click.To overcome some of the problems with hubs, bridges were created. But hubs had many disadvantages, such as not being aware of traffic that passes through them, creating one large collision domain, etc. In the past, the device was usually a hub. In a typical LAN, all hosts are connected to one central device.
![]() Each port is one collision domain, which means that the chances for collisions to occur are minimal. We have the same topology as above, only this time we are using a switch instead of a hub:Switches increase the number of collision domains. Imagine if you had 20 hosts connected to a hub, a packet would be sent to 19 hosts, instead of just one! This can also cause security problems, because an attacker can capture all traffic on the network.Now consider the way the switches work. The hub depicted above simply repeats the signal it receives out all ports, except the one from which the signal was received, so no frame filtering takes place. fast hardware-based bridging (using ASICs chips)Here is an example of the typical LAN network – the switch serves as a central device that connects all devices together:To better understand the concept of frame switching based on the hardware address of a device, you need to understand how switches differ from hubs.First, consider an example of a LAN in which all hosts connects to a hub:As mentioned previously, hubs create only a single collision domain, so the chance for a collision to occur is high. Here are other major advantages of Layer 2 switching: Mac emulator browserThis reduces traffic on the LAN and enhances security.
