For each malicious attack and threat identified in Assignment 1, choose a strategy for dealing with the risk (i.e., risk mitigation, risk assignment, risk acceptance, or risk avoidance). Masquerading – An attacker impersonates an authorized user to capture authentication information for use at a later date, resulting in possible unauthorized access to the network. An impersonation attack may be a replay or may be some other type of attack. Risk mitigation would be the best strategy for dealing

on every domain controller in the forest. This provides fault tolerance if one of the DNS servers is unavailable. In this way, domain controllers do not need to rely on other DNS servers for name resolution. This also simplifies the management environment because all domain controllers have a uniform configuration. Configure the Active Directory forest root domain controller to host the DNS zone for the Active Directory forest. Configure the domain controllers for each regional domain to host the

allocates and maintains unique codes and numbering systems that are used in the technical standards (“protocols”) that drive the Internet. IANA’s various activities can be broadly grouped in to three categories: * Domain Names IANA manages the DNS Root, the .int and .arpa domains, and an IDN practices resource. * Number Resources IANA coordinates the global pool of IP and AS numbers, providing them to Regional Internet Registries. * Protocol Assignments Internet protocols’ numbering

Communications. Discussion Question 1 Due Date: Day 4 [Main] forum. Post your response to the following: What is DNS? How do users benefit from it? Provide a brief description of the DNS process to resolve a URL to its IP address. DNS stands for Domain Name System and essentially operates like a phone book. It keeps a list of computer names and IP addresses. Instead of typing a numerical address into his or her web browsers address bar, a user can input the name of the computer (www. hotmail. com)

larger costumers with multiple domains or forests. After enabling the Global Names Zone, the administrator must manually create, add, edit and delete name records from that zone. It doesn’t support dynamic updates. 2. Explain the modifications necessary to DNS for accommodating Read Only Domain Controllers (RODC). How is this different from the way DNS handles ordinary domain controllers? All of the modifications required for accommodating a Read Only Domain Controller are handled through

DNS and DHCP, how they make your life easier DNS stands for domain name system, and DHCP stands for dynamic host configuration protocol. Most of the time they are used in conjunction with connecting to a network, though they are not reliant on each other, nor do you have to use either one to connect to your network. They just make the job of setting a network up that much easier, but you can still do everything manually if you choose to do so, it just won’t be anywhere near efficient. DHCP allows

DNS Server Role Updated: January 21, 2008 Domain Name System (DNS) is a system for naming computers and network services that is organized into a hierarchy of domains. TCP/IP networks, such as the Internet, use DNS to locate computers and services through user-friendly names. To make using network resources easier, name systems such as DNS provide a way to map the user-friendly name for a computer or service to other information that is associated with that name, such as an IP address.

deceiving not only the user but the computer as well, in order to change the real URLs to different IP numbers and consequently take the users to unwanted destinations. Moreover, pharming seeks to obtain personal or private information through domain spoofing. In other words, it poisons a DNS server by infusing false information into the DNS server, resulting in the redirection of the users request. However, your browser will still indicate that you are in a legitimate website making pharming

First let’s expand and define the acronyms DNS and DHCP. (DNS) Domain Name System is a database system that translates a computer's fully qualified domain name into an IP address. Then there is (DHCP) Dynamic Host Configuration Protocol) which is a network protocol used to configure devices that are connected to a network (known as hosts) so they can communicate on that network using the Internet Protocol (IP). Now in DNS networked computers use IP addresses to locate and connect to each other
