Hands-On Lab Training for CompTIA Security+ | Gain Practical Proficiency | arp

In this lesson, we will use the arp utility to assess organizational security.

We are in the arp portion of the video series. This lesson is part of a video series that prepares you for the hands-on portion of the CompTIA Security+ exam and is designed to give you hands-on experience with the Operations and Incident Response section of the exam. So, what is arp?

► What: The ARP (Address Resolution Protocol) command in Linux is a network utility used to display or manipulate the system's ARP cache.
► Who: Network administrators, system administrators, or users with appropriate permissions can use the ARP command.
► When: The ARP command can be used whenever there is a need to view or modify the ARP cache on a Linux system.
► Where: The ARP command is used in a Linux terminal or shell environment.
► Why: The ARP command is used to manage the ARP cache, which is a mapping between IP addresses and MAC addresses, helping in the communication between devices on a local network.
► How: To view the ARP cache, use the command "arp -a". To add or modify ARP entries, the "arp" command can be followed by options like "-s" for static entries, specifying the IP and MAC addresses, and "-d" to delete an entry. The rest of the 'how' is what this video is all about, so let's get into it!
