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.

How to create a function, called separate_int_and_str, which takes in a list and separates out the integer values and strings in
gregori [183]

Answer:

program :

def separate_int_and_str(list_1):# function to seprate the list.

   str_list=[] #list to hold the

   int_list=[]#list which holds the integer value.

   for x in list_1: #for loop to extract the list.

       if(type(x)==str): #if condition to check the type of the element.

           str_list.append(x)#create a list for the string value.

       elif(type(x)==int): #check condition for th einteger value.

           int_list.append(x)#create a list for the integer value.

Explanation:

  • The above-defined function is written in the python language, which used the code to separate the list for integer and the string value.
  • There are two lists define in the function which holds the integer and the string value separately.
  • There is a 'for' loop which scans the element of the list and checks the list by the help of type function which tells the class of the element.
  • Then if the type function states that the element is from the strong class, it will assign the element on the string list otherwise it assigns the element in the integer list.
