How to Install Active Directory on Windows Server 2008 Tutorial

• First Open Server Manager by clicking the icon in the Quick Launch toolbar, or from the Start > Administrative Tools > Server Manager.

• Wait till it finishes loading, then click on Roles > Add Roles link.

• In the Before you begin window, click Next.

1. In the Server Roles window, click on check box to select Active Directory Domain Services, and then click Next.
2. In the Active Directory Domain Services window read the provided information if you want to, and then click Next.
3. In the Confirm Installation Selections, read the provided information if you want to, and then click Next.
4. Wait till the process completes.
5. When it ends, click Close.
6. Going back to Server Manager, click on the Active Directory Domain Services link, and note that there’s no information linked to it, because the DCPROMO command has not been run yet.
7. Go to Start > Run then type DCPROMO then enter the Run command, or click on the DCPROMO link from Server Manager > Roles > Active Directory Domain Services.
8. Depending upon the question if AD-DS was previously installed or not, the Active Directory Domain Services Installation Wizard will appear immediately or after a short while. Click Next.
9. In the Operating System Compatibility window, read the provided information and click Next.
10. In the Choosing Deployment Configuration window, click on “Create a new domain in a new forest” and click Next.
11. Enter an appropriate name for the new domain. Make sure you pick the right domain name, as renaming domains is a task you will not wish to perform on a daily basis. Click Next.
12. Pick a full domain name such as “mydomain.local” or “mydomain.com”.
13. The wizard will perform checks to see if the domain name is not already in use on the local network.
14. Pick the right forest function level. Windows 2000 mode is the default, and it allows the addition of Windows 2000, Windows Server 2003 and Windows Server 2008 Domain Controllers to the forest you’re creating.
15. Pick the right domain function level. Windows 2000 Native mode is the default, and it allows the addition of Windows 2000, Windows Server 2003 and Windows Server 2008 Domain Controllers to the domain you’re creating.
16. Note: If you select “Windows Server 2008″ for the forest function level, you will Not be prompted to pick a domain function level.
17. The wizard will perform checks to see if DNS is properly configured on the local network. In this case, no DNS server has been configured, therefore, the wizard will offer to automatically install DNS on this server.
18. Note: The first DCs must also be a Global Catalog. Also, the first DCs in a forest cannot be a Read Only Domain controller.
19. It’s most likely that you’ll get a warning telling you that the server has one or more dynamic IP Addresses. Running IPCONFIG /all will show that this is not the case, because as you can clearly saw, I gave the server a static IP Address. So, this come from IPv6. I did not manually configure the IPv6 Address, hence the warning. In a network where IPv6 is not used, you can safely ignore this warning.by clicking on Yes,the Computer will use a dynamic assigned IP address (Not recommended)
20. You’ll probably get a warning about DNS delegation. Since no DNS has been configured yet, you can ignore the message and click Yes.
21. Next, if you want change the paths for the AD database, log files and SYSVOL folder. For large deployments, carefully plan your DC configuration to get the maximum performance.or leave it as default When satisfied, click Next.
22. Enter the password for the Active Directory Recovery Mode. This password must be kept confidential, and because it stays constant while regular domain user passwords expire (based upon the password policy configured for the domain, the default is 42 days), it does not. This password should be complex and at least 8 characters long (with capital latter, small latter and number combination). I strongly suggest that you do NOT use the regular administrator’s password, and that you write it down and securely store it. Click Next.
23. In the Summary window review your selections, and if required, save them to an unattend answer file. When satisfied, click Next.
24. The wizard will begin creating the Active Directory domain, and when finished, you will need to press Finish and reboot your computer.

          Reboot and you will have AD installed on your Win 2008 Server.

what is a computer firewall and how does it work

What is Computer firewall:

A wall between the source and the user that blocks a certain type of traffic from reaching its destination is firewall. The firewall protects systems from unauthorized access while maintaining communications with the legitimate ones. A device or a combination of devices configured to allow and reject transmissions in a network on the bases of well-defines rules works as firewall.

A majority of personal computers have built-in firewalls to defend the operating system from illegitimate efforts of transmitting or accessing data. Firewalls do have the capability to perform the routing functions where a number of routers are capacitated to act like firewall filters.

Network traffic has three features: a source, a protocol (typically UDP, TCP or ICMP) and a destination. The UDP and TCP protocols have a source (mostly random) as well as a destination port (a well-known number) for example the destination port of DNS is 53 and the destination port for HTTP is 80. The ICMP protocol carries an ICMP message type; the most common of them are Echo Reply and Echo Request. A firewall protection allows network security administrator to pick which ports and protocols or message types would have access and which would be blocked. Read below to find out how firewall works

How the Firewall Works?

The prime security feature of a firewall is its inbound restriction. A typical firewall configuration abandons all inbound traffic to internal IP addresses. A DMZ network should carry the server that accepts the incoming connections or traffic. Latest firewalls allow in the responses to outbound tariff; the firewalls of computers that are connected to web server via internet would automatically accept responses from the web server that would in turn return to the computer.

Inbound Confinement Example: A “ping” command transmits ICMP Echo Request message and as a response receives ICMP Echo Reply message. For blocking the ICMP Echo Request messages to reach its destination, one has to configure a firewall that would result in failed ping commands. For blocking ICMP Echo Reply messages a firewall could be assembled between the source and the destination to fail all ping commands. A potential attacker is allowed by ping to map the network; for preventing the use of ping command for mapping network disable the inbound Echo Request messages.

The outbound traffic is denied in some network security administrators. The feature forbids users from accessing unapproved protocols while limiting their access to only approved protocols; such restrictions involve avoiding users from online chat or sending outbound emails especially in work places. Such limitations are sensitive to work-around the time and effort of the user necessary to approach a particular protocol via indirect ways thus very few users spent time in figuring out a way. The outbound confinement most of the time works as per design.

Outbound Confinement Example: SMTP protocol that responds to TCP port 25 is used for emails. Blocking the outbound TCP port 25 in your network would disable the users from sending outbound emails except from enabled email servers. An effective work-around the confinement policy is the configuration of mail server to respond to an additional port along with port 25 by an intelligent user.

What are the Types of Firewall?
On the foundation of communication’s situation, its interception and the state firewalls could be classified.

• The Network Layer Firewall also known as packet filters (in BSD operating systems’ context) works on the low level of the TCP/IP protocol heap which means that none could cross the firewall unless the packets resemble the established rules. Usually default rules are applied but the administrator has authority to modify rules. The Packet Filters have two sub-types. A firewall could make use of a number of packet attributes for filtering traffic such as source port, IP address, destination port or IP address, destination service like FTP or WWW. The process of filtering could be based on protocols of the source such as net block, TTL values and other properties.
• • Stateful Firewalls manages the context of ongoing sessions and process speed packet by the help of state information. In case a packet does not resemble an existing connection then the evaluation would be based on the rules of new connections where the resemblance with the connection on the bases of comparison with the state table of firewall would enable the packet to cross the firewall without any further processing.
  • Faster filters and less memory requirement makes Stateless Firewalls a better option. These firewalls are fundamental for the filtering of stateless network protocols due to no concept of session in their set ups. The firewalls are not clever enough to figure out the extent of communication between the hosts.

 

• The Application Layer Firewall functions on the application level of TCP/IP stack such as all telnet or FTP traffic and tap all packets whether travelling from or to an application. They drop other packets without recognition of the sender. These filters are helpful in restricting outbound traffic from approaching the confined machine.

 

• The process ID of data packets is examined by the application firewall against a local process’ ruleset implied in data transmission. The rendered ruleset defines the extent to which filtering would be done. In this firewall the ruleset for standard services such as sharing services is very complex. Along with other processes there might occur some possible associations but these ruleset for process has fixed efficiency; it could not defend against modifications that are caused by exploitations such as the exploits of memory corruption.

 

• These limitations in the application firewall have triggered the association of a new generation of application named MAC (Mandatory Access Control) or sandboxing in these firewalls in order to secure sensitive services. APPArmor is an example of next generation application firewall that is included in some distributions of Linux.

 

• A Proxy Server could be configured to act as a firewall by responding to input packets such as connection requests. The server could serve as an application that runs on software of a machine made for this purpose or on a hardware dedicated to the task thus breaking into the path of other packets so they could not access their destination.
  It would be extremely tough for an external network to temper with an internal system that is synchronized with a proxy server. If the application proxy is accurately configured and intact then the misuse by an external network would not inevitably lead to some security breach exploitation. A system that is in the reach of public might be hacked by intruders who would employee the system as a proxy for their illegitimate motives; in such cases proxy would present that machine as it is to the internal computers. For passing packets to a specific target, hijackers could make use of IP Spoofing.

 

• The function of NAT (Network Address Translation) is often installed in firewalls that give private or personalized address range as given in RFC 1918 to the hosts that are secured behind a firewall. The initiative is taken to protect or camouflage the hosts from potential threats.

 

• The routable addresses of IPv4, assigned to individuals or organizations to reduce the number along with cost of acquiring such public addresses for every other computer in the building, were the reason behind the designing of a function like NAT. Against network reconnaissance the best defense is to hide the address of protected devices.

what is spam in computer networking? How spam works?

What is Spam?

When we use different types of technologies related to the field of computer networking, we should know about the different types of advantages and disadvantages of the technologies. As we know that there are lot of advancements in the computer networking field but still these technologies has a security issue in there working. However, one of the major disadvantages of the computer networking is that they can easily affected by different types of methods from different source without the permission of the users. One of them is Spamming. Read further below about what is spam.

An other important types of such infection that can affect the system badly is the Spam. It is the types of messages or the email that can infect your personal computer and decode all the important information related to your computer called as spam. It is that types of system that can infect the PC with the help of different types advertising messages or email downloaded from the net that are unwanted and stored in the email box with out the permission of the user.

How spam Works?
Spam is the type of the unwanted or infected messages that infect the personal computer and slows down the working of the computer. Spam works in number of ways some important that is used by the spammers to spread the spam in enter networks and also in your systems are as follows.

When we move on to the network with the help of different networking devices, there are lot of advertisements present on the internet the can provide some good offers to the customers such as some sale purchase offer or some kind of games etc. But in these advertisements spammers use different techniques to store the infected messages in it and when we click to open the ad, the email works and decode the information and the working of the system become very slow and it can also hijack the personal information of your system.

Characteristics that makes email Attachments dangerous: There are several factors that make Email attachments dangerous because sometimes the most attractive feature of emails allows different types of attackers to harm your id. some of these features are listed below.

Easy and random circulation: One of the important features of email that makes it dangerous sometime is the easy circulation when you and some attachments in your mail box it can be viewed or forwarded to the different unwanted users. Forwarding of the email quickly entertains viruses to harm your computer system. This happens because the attackers can easily track your address they can easily guess that which uses opens every mail message without bothering the security and the source from where mail is coming from.

Broadcast emails: Broadcast mails are those mails that provide certain kind of message to the users or group of users. They travel randomly within the networks and can carry the infection. Many attackers can also compose these messages to harm the entire network especially in client serve connections all the client systems can get infected easily.

Use friendly options and programs: Many email service providers offers the automatic download of the attachment by just clicking the file .this could also be very harmful for the computer system which can affect the computer file system just in the matter of seconds.

Precautions for the protection: Although transferring information from one place to another and dealing with online files and services can be risky but there are some steps that can be followed for preventing the harmful and spam mails.

Beware of unwanted attachments: always stay conscious for the mail message that are not requested even from the people you know especially mails with the subject from mom, from dad etc .because attacker always tricks  the computer users to trust the mail message easily that they send.

What is digital signature ? concept of digital signatures

Understanding digital signature:

Digital signatures are used to present any type of digital data, message or file in the form of numbers or mathematical format. It’s a technique which is used for verifying the authenticity of the message and the user. It tells the receiver of the message that it has been sent by the known source and it also confirms that file is secure to be explored. They are most often used for the financial dealings and transactions and also in some scenarios where the delivery of information is required to be confidential. They can be referred as the type of electronic signatures but we cannot say that all electronic signatures are digital signatures. In some countries of this world they are considered to be the important part and instrument of significance in sensitive issues for instance in US parliament digital signatures of the all the national members are used to authenticate the received information.

Historical Background:

The concept of digital signatures are first originated by the White field Daffier and Martin Hellman in 1976.at first their scheme was considered useless but with the passage of time the effective algorithms were designed that strongly supported the concept of digital signatures. Later on proper soft wares for data authenticity were developed which became very famous in the world. One of the most famous software for digital signatures is Lotus Notes 1.0 which was officially released in 1989, this software uses RSA algorithm for data cryptography.

How digital signature works:

Digital signature works by the integration of three algorithms which are implemented in a sequence to make the message in the digital signature format. Private, public and corresponding keys are built in digital signatures to enhance the security and authenticity. At first the very first private key that is assigned to the message verifies the authenticity of the public key and after that flexible computational signatures are developed in this way the information become unknown to the irrelevant parties.

Why digital signature are used ?

There are different reasons for which digital signatures are used

Efficiency: Digital signatures are efficient because they are comparatively shorter in length and takes very small portion of the memory the technique for shortening the digital signatures is known as hashing.

More  compatibility: Digital signatures are more compatible because they are operated on domains and are not at all independent. Leading signatures scheme are implemented on the domains. This feature makes the signature much useful.]

Enhanced  integrity: Without the hash function the digital signature offers the enhanced integrity. If the boxes that appear to the receiver in form of sign are not properly arranged then receiver would not be able to recognize the message. This is one of the features that provide good security as well.

Authentication: We have commonly seen that the entire message that is communication contains the information of the entity both at the sender and receivers end. One of the most important purposes of using the digital signature is the authentication of the source of the messages. Secret keys are assigned that can be recognized only by the matching key at the receiver end. This keeps the network threats and unauthenticated and illegal use of the message

Non repudiation: one of the distinguishing feature of digital signatures is that once signed by the entity , it cannot be denied when transmitted over domains

Uses of digital signatures

Digital signatures are used in the aspects of life and world where security matters a lot. Many governmental and confidential organizations prepare their important and private document in the form of digital signature which assures the security.

WiMax Coverage Areas

WiMAX Coverage:

In this present era there is need of two things; speed and mobility and these two factors knock the door at Coverage. For speed there is broadband and for mobility there is WiFi/ Wireless networks. Now the only way to get both things together is to merge them and now we have WiMAX that boast both speed and mobility combined together with wider WiMAX coverage. The standard is set for this new technology and speed is also guaranteed as it goes for the last mile when there is requirement to send data. IP protocol has been utilized to attain the broadband characteristic over the WiFi networking since the WiMAX technology introduced to provide last mile WiMAX coverage.  

WiMax coverage is approximately 40 Mbit/s and is going to touch 1 Gbit/s for fixed users in the near future. Similarly, fixed users can access WiMAX  and it ranges 50 km or in other words 30 miles. The case for the mobile user is different. It could not go to that extent as stationary customers. For mobile users the WiMax coverage is 5-15 km or 3-10 miles. Here you can see that WiFi is already there to provide around 30-100 m or 100-300 feet which is much higher than WiMAX. The main reason as preferring WiMax is that it is receiving high frequency band to operate. It supports all frequencies to perform wireless function well n good.

WiMAX as a wireless broadband service is welcoming by the customers in perspective of speed and reliability. It works as a wireless backhaul, supports broadband connection and also acts hot spots. It is quite familiar to WiFi but gives better coverage when compared.
WiMAX is going to give tough competition to the DSL operators with quality service and broadband connectivity. It is also very cheap as compared to WiFi and other internet service providers. It is only profit-oriented service.

It is acting as a backhaul for previous all wireless standards for up-gradation. It is good when talk about services like VoIP, IPTV and data transmission.
