Ping, a computer network management tool, is used to determine whether a host is reachable on an IP network. ARP protocols To begin, launch Wireshark and the ecet-375 Web Browsing. Pcap capture file. This capture file was created while browsing the Internet.
<h3>What does ping operates mean?</h3>
- Ping sends an ICMP Echo Request to a predefined network interface and then waits for a response. A ping signal is sent to the specified address when a ping command is issued.
- The destination host sends the echo reply packet in response to receiving the echo request.
- A ping is the time it takes for a small data set to be communicated from your device to an Internet server and back to your device (latency is the more accurate technical word). Ping times are measured in milliseconds.
- Ping is the most commonly used TCP/IP command for troubleshooting connectivity, reachability, and name resolution.
- This command displays Help content when run without any parameters. You can also use this command to verify the computer's name as well as its IP address.

Seven Domains of IT Infrastructure Seven domains can be found in a typical IT infrastructure. They are as follows: User Domain, Workstation Domain, LAN Domain, LAN-to-WAN Domain, Remote Access Domain, WAN Domain, and System/Application Domain.
Explanation:
User Domain : The User Domain covers all theusers (of any rank) that haveaccess to the other six domains.
RISKS:
-
User can destroy data in application(intentionally or not) and delete all
- User can insert infected CD or USBflash drive into the work computer
Workstation Domain : A computer of an individual user where the production takes place
RISKS:
- The workstation’s OS can have a known software vulnerability thatallows a hacker to connect remotelyand steal data.
- A workstation’s hard drive can fail causing lost data
LAN Domain : Contains all of the workstations,hubs, switches, and routers. TheLAN is a trusted zone
RISKS:
-
A worm can spread through the LANand infect all computers in it.
- LAN server OS can have a knownsoftware vulnerability.
WAN Domain : Stands for Wide Area Network and consists of the Internet and semi-private lines
RISKS:
- Service provider can have a major network outage.
- Server can receive a DOS or DDOS attack.
- A FTP server can allow anonymously uploaded illegal software
LAN / WAN Domain : The boundary between the trusted and un-trusted zones.The zones are filtered with a firewall
RISKS:
- Weak ingress/egress traffic filteringcan degrade performance.
- A firewall with unnecessary portsopen can allow access from the Internet
System / Application Storage Domain : This domain is made up of user-accessed servers suchas email and database
RISKS:
- A fire can destroy primary data
- A DOS attack can cripple the organization’s email
Remote Access Domain :The domain in which a mobileuser can access the local network remotely, usually through a VPN
RISKS:
- Communication circuit outage candeny connection.
- Remote communication from officecan be unsecured.
- VPN tunneling between remotecomputer and ingress/egress routercan be hacked
