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
I haven't really used either, but people I know would prefer using Audacity.
Answer:
yes it can communicate with all interfaces on the router.
Explanation:
PC1 has the right default gateway and is using the link-local address on R1. All connected networks are on the routing table.
Netsh may be a Windows command wont to display and modify the network configuration of a currently running local or remote computer. These activities will tell you in how manny ways we can use the netsh command to configure IPv6 settings.
To use this command :
1. Open prompt .
2. Use ipconfig to display IP address information. Observe the output whether IPv6 is enabled, you ought to see one or more IPv6 addresses. A typical Windows 7 computer features a Link-local IPv6 Address, an ISATAP tunnel adapter with media disconnected, and a Teredo tunnel adapter. Link-local addresses begin with fe80::/10. ISATAP addresses are specific link-local addresses.
3. Type netsh interface ipv6 show interfaces and press Enter. note the output listing the interfaces on which IPv6 is enabled. Note that each one netsh parameters could also be abbreviated, as long because the abbreviation may be a unique parameter. netsh interface ipv6 show interfaces could also be entered as netsh ipv6 sh i.
4. Type netsh interface ipv6 show addresses Observe the results of the interface IPv6 addresses.
5. Type netsh interface ipv6 show destinationcache and press Enter. Observe the output of recent IPv6 destinations.
6. Type netsh interface ipv6 show dnsservers and press Enter. Observe the results listing IPv6 DNS server settings.
7. Type netsh interface ipv6 show neighbors and press Enter. Observe the results listing IPv6 neighbors. this is often almost like the IPv4 ARP cache.
8. Type netsh interface ipv6 show route and press Enter. Observe the results listing IPv6 route information.
Answer:
True but it might be false but i think is true
I usually use the Ohm meter to check for resistance. If the circuit completes, the measurement is negligible.
