One computer may have multiple MAC addresses. If not, why not, and what could be the underlying cause?
Step by step
Solved in 3 steps
- The MAC or physical address of a computer attempting to log on to a network can be used to restrict access. Examine this process and identify methods used by hackers to circumvent this restriction. How do you identify the MAC address on a system? How does a switch identify the MAC address? Share your findingsShort questions: Q. What is The Compressed form of Network Access Protection in Computers?How is a botnet used in a DDoS assault?
- Is there a procedure you'd follow if you discovered that two devices on your LAN had the same MAC address? Just what are the potential repercussions of my action? Okay, so how does this system work? Would it be possible if both computers used the same local area network server? If both devices try to access the same remote web server, what would happen?Please assist with this lab: 2.16 LAB: Port Scan (Modules) In network security, it is important to understand port scanning. Hackers use tools to scan a network and determine if there are open ports and if they contain some sort of vulnerability. To scan ports, you first have to find active hosts on a network. Once you find active hosts and discover a list of IP addresses for those hosts, a port scan can be performed to gather information about open ports and analyze services running on those ports. A port scan is the process of sending packets to an active host's ports and learning details that can help you gain access to that host or to discover open vulnerabilities on your network. Some common ports are: Port 20 - File Transfer Protocol or FTP Port 22 - Secure Shell protocol or SSH Port 23 - Telnet protocol for unencrypted transfer Port 80 - HyperText Transfer Protocol or HTTP Port 443 - HyperText Transfer Protocol Secure or HTTPS The Well Known Ports are those from 0 through…How can one person launch a DDoS attack?
