Questions On Dynamic Host Configuration Protocol 5

We have been engaged in business for some time, and have been very successful, however we need to re-examine our network configuration and infrastructure and identify that our network defenses are still reliable, before we make any changes. We need to take a hard look at our current configuration of host, services and our protocols within our organization. Data from a large number of penetration tests in recent years show most corporate networks share common vulnerabilities. Many of these

This file holds the hostname and IP address of the local system. It also holds a special

When you type in a web address, e.g.www.google.com. DNS associates with the domain name, translates into IP address (for example 192.168.154.70 is the IP for google.com) and directs your Internet connection to the correct website.

DNS is the service that translates from domain name to the matching IP address. The roles of the name servers in this process are:

The alternate domain name (CNAME) is the place where you’ll put the URL to pull the content from.

53. Can you confirm that the server has network access and has been registered in an ISO-approved centralized

The IP address is given a unique identification it is one of kind IP address, so it can be trace for any internet activity and find the exact location of website. Domain names are used because it is easier to remember the name rather than the entire website address. All computers on the net have what area unit termed net Protocol addresses ordinarily called associate degree scientific discipline address to be ready to communicate across the network. These addresses, that area unit assigned to all or any computers on a network, area unit created of numerals separated by a dot that don't seem to be essentially simple for North American country to recollect. Therefore, whereas computers simply use these scientific discipline addresses to attach and communicate with one another, it's somewhat more difficult for North American country. It's with keeping such in mind that, net designers and controllers have return up with a translation system that identifies additional simply remembered characters with every and each scientific discipline address. With DNS we need to have the integrated namespace so following DNS use is proposed: an internal DNS namespace, used only on your own network; internal DNS to communicate with external DNS forwarding; and an external DNS namespace to communicate with external

DNS stands for ‘Domain Name System’. It is an internet service that works like a

The security aspects we should watch for in this lab relate mostly to the righty way of configuring the services well, setting up a strong and complex Administrator password. Also we must set up firewall rules to make sure that all iptables rules give access to what’s needed only. In firewall rules, we should allow incoming and out coming DNS and DHCP traffic from and to known ip addresses and ports that we needed to connect to. Moreover, in this lab we used the Microsoft Baseline Security tool, which gives good security alerts about critical security issues and controls in the Windows system unlike Linux where SELinux was restricting access rather than giving alerts.

This Dragon Net Solutions (DNS) Access Control and Account Management Plan details the access control and account management activities for Dragon Net Solutions. It facilitates compliance with the National Institute of Standards and Technology’s (NIST) Recommended Security Controls for Federal Information Systems (NIST 800-53) and the NIST Guide for Accessing the Security Controls in Federal Information Systems (NIST 800-53A). Specifically, the following NIST Access Controls (AC) are addressed:

where ServerName is the Name of the Domain Controller you would like to view Ex- “Server15.domain15.local”

The IIS7 splash screen appears. It is the default webserver and has no HTML codeing and is resolved by DNS

● When the expected zone does not include host S, a path from host S to host D must include hosts outside the expected zone. Therefore, additional region must be included in the request zone, so that S and D both belong to the request

In the Zone name text box, type the internal domain name from the diagram you created in Exercise 12.1

P1: The first method in network addressing is, Fully Qualified Domain Name which is known as FQDN for short. FQDN is used as the domain name for a specific host or computer name on the internet. FQDN consists of two main parts, the domain name and the hostname. For example, Belfast Met is the hostname, but the domain name is belfastmet.ac.uk.
