...Abstract--- This document provides an analysis and comparison of IPv4 and IPv6 under various circumstances. It is well understood that IPv6 has been designed to replace IPv4. We have done a feature-by-feature comparison and contrast of IPv6 versus IPv4 and found that IPv6 offers many unique opportunities for increasing a network architectures efficiency and agility. In some sense, there is a competition going on between these protocols, as they are not directly compatible, and network providers and users are being forced to determine whether to support one or both protocols for various network services. The new version of IP,(i.e. IPv6), constitutes an effort to overcome the inborn limitations of IPv4, in order for the new protocol be able to respond to the new needs as they shape today in the Internet. This paper is aimed to discuss about various comparison issues when porting an IPv4 application to IPv6 with focus on issues that an application developer would face rather than a complete API reference.IPv4 is the incumbent and currently has the most widespread usage for conventional Internet applications.IPv6 is a large-scale re-design and re-engineering of IPv4, based on many lessons learned as the IPv4-based Internet grew and was used in unforeseen ways. Keywords-- IPv4, IPv6, Multicast, Quality of service (QOS), Routing. I. INTRODUCTION HE primary motivation for change arises from the limited address space. When IPV6 deployed on a large scale it has...

...The fire wall ports that you must have open are HTTP and RSTP, so that is port 80 and 554 respectfully. HTTP is used often as protocols on the web. The reason you should open both is because it uses a thing called Protocol rollover. Protocol rollover is used to negotiate the most efficient protocol they have in common. It’s possible to specify which protocol the administrator wants to use with URL prefixes. It is very effective to enable both protocols to add an overall better user experience. SSL is the recommended security method for running the Windows Media Administration site. Secure Socket Layer provides the highest level of security by encrypting data before it’s sent over the network according to Microsoft’s web site. It still has to be used with another authentication method as well. Personally, I feel like basic authentication offers some advantages. One of those advantages is that the users have to have a username and password to access the website. The administrators manage the usernames and passwords as well. Basic authentication also works with most browsers, easy to manage and easy to use. One downfall is that the credentials are not encrypted. That one downfall is a huge security risk that most wouldn’t be willing to take. As a network admin you want the risk to be as low as possible. Confidentiality, integrity and availability are the most important keys when running a network. The three protocols used by Windows Media Services to administer the server are Real...

...NT2670 Midterm Study Two basic types of computers that can be on an enterprise network are ____________. Which of the following roles enables users working at another computer on the company network or on the Internet to establish a connection to a server and open an application or desktop session there? Terminal Services By using the Server Core installation option of Windows Server 2008, you get a stripped-down version of the operating system that shows a single window with a command prompt. The ServerManagerCmd.exe utility provides a command prompt alternative to Server Manager and can be used to install roles and features from scripts or batch files. You must activate Windows Server 2008 computers within 30 days of installing them. The Add Roles Wizard provides roles that fall into three basic categories: Directory services, Application services, and Infrastructure services. Which of the following correctly identifies the HTTP binding options available? IP address, Port Number, Host Header What is the original default filename for the Web? Index.html FTP7 can use SSL to encrypt its authentication traffic before transmission. IIS7 uses a generic request pipeline that is modular in nature. The component that manages the request pipeline, the server’s application pools, and the worker processes is called WPAS-Windows Process Activation Service.

...Matthew Klutts NT2670 2/21/2016 Project part 1 I do this IIS or Internet Information Services is the best choice for an application server. This is because it is a windows system. It provides a secure, easy to manage, modular and extensible platform for hosting websites, services and applications. With IIS you can maximize web security with a reduced server foot print and automatic application isolation. IIS 7.0 and up have a modular architecture. Modules, also called extensions, can be added or removed individually so that only modules that are required for specific functions are installed. IIS in my opinion will be the best choice for this server, because of all the information that I provided above, and the fact that I’m more comfortable with windows based systems. The ports that need to be open to host ftp, http, https, and streaming media are listed below. 1. FTP a. The default port range is 1024-5000, but the upper range can be changed. 2. HTTP b. Port 80 or port 8530 3. HTTPS c. Port 443 or port 8531 4. Streaming media d. Windows Media server uses TCP in ports to accept an incoming HTTP connection (80), RTSP connection (554), MMS connection (443). e. Windows Media Server uses UDP out ports 1024-5000 and 5004. Due to the design of IIS and its security features I don’t see many security concerns with having all these ports open on the same server. Although there is no way for any system to be completely safe...

...After careful consideration, it was decided by the corporate IT team that in order to increase security and lower your attack surface, Windows 2008 Server Core would be installed on a group of your servers. However, a few roles need to be installed on the server, and your Senior Administrator is not familiar with installing roles on a Server Core machine. Use notepad to create a batch file to install the following roles: DHCP, DNS, Print Services and Hyper-V. Questions: 1. What does the /w switch do? Why is it used? The /W switch specifies the warning level of the MIDL compiler, and the level indicates what type of security warning level is present. The security levels range from 0-4. Zero meaning no warning and four being the highest level. 2. What switch is used to remove a role? /remove will remove all the roles specified on the computer. 3. What is the command to start the DHCP Server service? The netsh command will start the DHCP server. 4. What command is used to configure a DNS zone?

...After viewing this video for at least 5 times plus watching another to come to the conclusion listing the steps to get sound understanding since I couldn’t complete the final two labs. Pre-Installation Checklist Make sure you have all of the following steps in place before you setup Exchange Server 2010 on Windows Server 2008 R2 64 Bit and this is for a small office for both the Active Directory and the Exchange Server. But if you have a larger office you may want to consider separating the Active Directory machine and the Exchange 2010 Server. Install Windows Server 2008 R2 64 bit version Exchange 2010 is a 64 bit application and requires 64 bit versions of Windows Server 2008; therefore only a computer capable of running the 64 bit version of 2008. Once that is done named the server (mailitsupport.com), set the clock and it’s configured to be a stand alone with default settings. Configure Your Static IP Address The default installation of Windows 2008 sets your IP v4 and IP v6 addresses to use DHCP. Since we will be configuring this computer to be a domain controller, you must change the IP address of the computer to be a static IP address which should be done via View Network Connections" in the Server Manager screen. This will display the list of active network interfaces. a. Double click on your network adaptor to display the adaptors status. b. Press the Properties button. c. Highlight "Internet Protocol Version 4 (TCP/IPv4)" and then press the Properties...

...Apparently many designers and developers believe secure passwords have to look complicated, even these days. The most secure ones seem to be „ #sK8/a_C%eD8)“. This looks like hell and is a mess to create. How would you explain your user, the password has to have a length of at least 8 characters, 2 characters have to be uppercase, 2 have to be special characters and of course numbers are a must? Would you like to create such a password? I wouldn’t. Instead I would probably risk it to write down this password on a note or use the same password several times. Maybe I would use a password manager. Nothing is a really great idea. Such complex requirements for passwords are a huge problem for privacy and IT security. But we need these passwords! At least this is, what passwordsgenerater.net wants to tell us. NO! We don’t need overly complicated passwords. This claim is idiocy. I don’t have any idea who invented this legend, but this person has to hate us. So much websites, apps and whatever demand us to use such passwords without any logical reason. If the safety of passwords relied on the number of different characters, how can our iPhone be safely protected by a 6-figure passcode? This is just 1,000,000 possible combinations. They did something, at least theoretically, pretty easy. The „Secure Enclave Processor“ (a pretty cool piece of hardware) restrict how often you can enter a wrong passcode. Furthermore they do one more thing: they set a hardware delay between the inputs...

...Unit 7 Assignment 1 – Designing an Exchange Server (Portfolio) The first lesson that was given in this course NT2670 the more roles the server has the greater the physical it requires. The fact that a server is already using roles such with email server would require a lot. Especially over 1000 clients would require a lot of power with no minimum cut-off of system requirements. At least at the very least it should have 2 cores, but 4 cores is becoming standard, and I would choose 4 cores, it is also cost effective. Also building an Exchange Server 2007 I would pick a server with mid level capabilities in which it can handle at least 17 roles. However there will need to be at least 7-8 roles that need to be installed in Exchange Server 2007. To increase speed in the network I would choose the Thecus N5550 Enterprise Tower NAS server – Intel Atom Processor, 2 GB DDR3, RAID 0/1/5/6/10, 2x RJ-45, 1x USB 3.0, 1x HDMI, No OS. The cost for two of these severs are $419 2x which come to around $900 plus tax, to have the capabilities a business needs to be running with room to expand. Given that the minimum requirement for Windows Server 2008 requires 2 cores and 4 gigabytes of ram this is more than enough for Exchange 2007. The network requires 1000 emails to be managed, CAS, Hub Transport, and UM roles. This will only require RAID 5 setup because of the Client Access Server, all exchange server need to fast transfer rates and fault tolerance and the Thecus N5550 is more than up...

...Nick McCoy Email and Web Services NT2670 5 August 2014 TLS VS SSL As some know TLS (transport Layer Security) and SSL (Secure Socket Layer) are protocols that encrypt data and authenticate applications and servers. But some people don’t know what the difference is between these two. Well, I’m going to shed some light on that and make it easier to understand. A lot of people think that TLS and SSL are used interchangeably or are in conjunction with each other they are right but not fully correct, and the reason is one is not like the other it is a predecessor of the other and here is why. SSL served as a basis for TLS now with that being said some refer to it as SSL 3.1 So the difference would be that SSL is by port and TLS is by protocol, so that’s the difference. SSL and TLS are not compatible for instance if you have a program that can only speak SSL and not TLS, but want to connect to the service that only supports TLS you just cannot simply do it the reason is the program you are using wants to talk security first, but when it is received on the TLS end it wants to talk business first they don’t mix you cannot do it, so they are not compatible with each other. It’s like trying to fit a square in a triangle block in a square hole cannot do it. Is TLS or SSL more Secure? Let’s find out. TLS is the winner no matter what version and the reason are TLS v1.0 is more reliable than SSL v3.0 which is TLS predecessor, but however Versions 1.1 and 1.2 of TLS are far more secure...
