Define tunneling in the VPN environment and explain the difference between voluntary and compulsory tunnels Solution Tunneling is a way in which data is transferred between 2 networks securely. All the data being transferred is fragmented into smaller packets or frames and then passed through the tunnel.this process is different from a normal data tranfer between nodes. Every frame passing through the tunnel will be encrypted with an additional layer of tunneling encryption and encapsulation, which is also used for routing the packets to the right direction.this encapsulation would then be reverted at the destination with decryption of data which is later sent to the desired node. A Tunnel is logical path between the source and the destination endpoints between two networks.Every packet is encapsulated at the source and de capsulated at the destination.this process will keep happening as long as the logical tinnel is persistent between two endpoints. tunneling is also known as the encapsulation and transmission of VPN data or packets. IPSec tunnel mode enables IP payloads to be encrypted and encapsulated in an IP header so that it can be sent over the corporate IP internetwork or internet. IPSec protects secure and authenticates data between IPSec peer devices by providing per packet data authentication. IPSec peer can be teams of hosts or teams of security gateways. Data flows between IPSec peers are confidential and protected. The source and destination addresses are encrypted. The original IP datagram is left in tact. The original IP header is copied and moved to the left and becomes a new IP header. The IPSec header is inserted between these two headers. The original IP datagram can be authenticated and encrypted. The tunnel is the logical path or connection that encapsulated packets travel through the transit internetwork. The tunneling protocol encrypts the original frame so that its content cannot be interpreted. The encapsulation of VPN data traffic is known as tunneling. The Transport Control Protocol/Internet Protocol (TCP/IP) protocol provides the underlying transport mechanism for VPN connectivity. The two different types of tunneling ar e : In this case, the client dials-in to the remote access server, by using whichever of the following methods: The remote access server produces a tunnel, or VPN server to tunnel the data, thereby compelling the client to use a VPN tunnel to connect to the remote resources.

IP Security One problem with Internet protocol (IP) is that it has no method for confirming the authenticity and security of data as it moves through the net. IP datagrams are typically routed between devices over disparate networks; as a result, information within these datagrams could be intercepted and altered. As use of the Internet for critical applications has increased, the need for enhancements to IP security became necessary. As a result, the Internet Engineering Task Force (IETF) created a set of protocols called IP Security, or IPsec, to support the secure exchange of packets over the Internet. IPsec is now a mandatory component of IPv6 and must be supported for any IPv6 implementation. IPsec is implemented in IPv6 using the authentication header (AH) and the encapsulating security payload (ESP) extension header. Answer the following questions in a 3- to 4-page, APA-formatted paper: 1 What is IPsec, and why is it necessary? How is IPsec used in VPN? 2 Which network layer currently suffers from attacks, and why? At which layers of the network stack architecture should a solution be attempted? Provide details. 3 How is IP security achieved? What is the basic authentication scheme? Which mechanisms are used? What are some of the application venues of IPsec? 4 How is a VPN implemented on a server so that its clients can connect to it? Remember to properly cite your sources according to APA guidelines. Solution IPSec IPsec also known as IP Security.Internet Protocol Security is a framework for a set of protocols that provide security for internet protocol. It can use cryptography to provide security. IPsec support network level data integrity, data confidentiality. As it is integrated at the internet layer (i.e. layer 3), it provides security for all the protocols in the TCP/IP. IPsec applied transparently to the applications, there is no need to configure separate security for each application the uses TCP/IP. IPsec provides security for IPsec provides two choices of security service: Authentication Header (AH), which essentially allows authentication of the sender of data, and Encapsulating Security Payload (ESP), which supports both authentication of the sender and encryption of data as well. The specific information associated with each of these services is inserted into the packet in a header that follows the IP packet header. Separate key protocols can be selected, such as the ISAKMP/Oakley protocol. IPsec is necessary for Earlier security approaches have inserted security at the Application layer of the communications model. IPsec is said to be especially useful for implementing virtual private networks and for remote user access through dial-up connection to private networks. A big advantage of IPsec is that security arrangements can be handled without requiring changes to individual user computers. Cisco has been a leader in proposing IPsec as a standard (or combination of standards and technologies) and has included support fo.

difference between Gre tunnel and vpn tunneling? Solution 1. VPN tunneling means Virtual private networks. This network is used to connect two locations for transferring the data over the two locations using internet. Where GRE means Generic routing encapsulation. This will create private point to point connection between two networks for transferring the data using internet. 2. VPN tunneling uses many number of Encryption methods to secure the data while transferring the data, so that the data cannot be attacked by the third party. GRE tunneling uses the Encapsulation method to transfer the data. That means the encapsulated packet will be routed using internet to the destination. It works with the encapsulating the payload. When the packet is encapsulated the inner packet payload will not change. As the outer packet reaches the destination the encapsulation is removed and the final payload is forwarded to the destination. 3. VPN tunneling requires an internet connection and some software applications and some installations. So it is less expensive and less installation to connect the two new networks. GRE tunneling does not have any mechanisms for the flow control and security by default. By this feature this tunneling can be easily configured. 4. VPN tunneling cannot forward the data from discontiguous network through a single tunnel. GRE tunneling can forward the data from discontiguous network through a single tunnel. 5. VPN tunneling cannot be used to forward multicast traffic. GRE tunneling can forward multicast traffic. By this reason advertisements sent by routing protocols can be easily transferred between remote sites. .

Introduction: Transport Layer: Transport Layer forms the base of the internet which is included in both OSI model as well as TCP/IP model. Its functionality differs in both the models providing appropriate services like flow control, connection-oriented data stream support and multiplexing. . The transport layer provides endwise communication services for applications within a layered approach of network components. Segmentation is the process of dividing the data stream or the contents of message into packets. Whenever a command is issued in a TCP/IP application layer protocol, a sequence of events gets initiated. The message or command first passes through the stack TCP/IP protocol stack in a personal system. It then passes across the network media and protocols on a distant or remote system. At every layer the protocols on the sending host adds information to the actual data and also interacts with the peers on the receiving host. Security using Data Encapsulation: Information is transferred across a network in the form of packets. Every packet consists of a header with the address of sending and receiving systems and a body with data to be transferred. The process in which a protocol on the sending host adds data to the packet header is named data encapsulation. Every layer has a different term for the altered packet, like a packet on a Transport layer is termed as TCP segment, IP diagram in Internet layer, Frame in data link layer and physical Network layer. Protocols in Transport Layer: The most commonly used transport protocol is the Transmission Control Protocol (TCP). It is used for connection-oriented transmission(s), whereas the other connectionless i.e. User Datagram Protocol (UDP) is used for simpler messaging transmission applications. TCP is the more complex protocol, due to its design which incorporates reliable transmission and data streaming services. Other protocol examples in this group are the Datagram Congestion Control Protocol (DCCP) and the Stream Control Transmission Protocol (SCTP). Packet - Packaging the Transport Layer: With Transport layer segment or datagram the network can deliver data/information to the destination host. The IPv4 encapsulation remains in place from the time the packet leaves the Network layer of the originating host until it arrives at the Network layer of the destination host. The process of encapsulating data by layer enables the services at the different layers to develop and scale without affecting other layers. This means that transport layer segments can be readily packaged by existing Network layer protocols, such as IPv4 and IPv6 or by any new protocol that might be developed in the future. Routers can implement these different Network layer protocols to operate concurrently over a network to and from the same or different hosts. The routing performed by these intermediary devices only considers the contents of the packet header that encapsulates the segment. In .

Create your own variant of both a hiring and a termination policy related to security and keeping company info secure. Solution Information Security management is a process of defining the security controls in order to protect the information assets. Security Program The first action of a management program to implement information security is to have a security program in place. Security Program Objectives: Protect the company and its assets. Manage Risks by Identifying assets, discovering threats and estimating the risk. Objects are- Information Classification, Security Organization, and Security Education. Security Management Responsibilities: Determining objectives, scope, policies,re expected to be accomplished from a security program. Evaluate business objectives, security risks, user productivity, and functionality requirements. Approaches to Build a Security Program Security Controls Security Controls can be classified into three categories- Administrative Controls, Technical or Logical Controls ,Physical Controls. The Elements of Security Vulnerability: Vulnerability characterizes the absence or weakness of a safeguard that could be exploited. Threat: Any potential danger to information or systems. A threat is a possibility that someone (person, s/w) would identify and exploit the vulnerability. Risk: Risk is the likelihood of a threat agent taking advantage of vulnerability and the corresponding business impact. Reducing vulnerability and/or threat reduces the risk. Exposure: An exposure is an instance of being exposed to losses from a threat agent. Vulnerability exposes an organization to possible damages. Countermeasure or Safeguard: It is an application or a s/w configuration or h/w or a procedure that mitigates the risk. The Relation Between the Security Elements Example: If a company has antivirus software but does not keep the virus signatures up-to-date, this is vulnerability. The company is vulnerable to virus attacks. The likelihood of a virus showing up in the environment and causing damage is the risk. .

Determine the valuation of long-term liabilities. Donald Lennon is the president, founder, and majority owner of Wichita Medical Corporation, an emerging medical technology products company. Wichita is in dire need of additional capital to keep operating and to bring several promising products to final development, testing, and production. Donald, as owner of 51% of the outstanding stock, manages the company\'s operations. He places heavy emphasis on research and development and long-term growth. The other principal stockholder is Nina Friendly who, as a nonemployee investor, owns 40% of the stock. Nina would like to deemphasize the R&D functions and emphasize the marketing function to maximize shortâ€“run sales and profits from existing products. She believes this strategy would raise the market price of Wichita\'s stock. All of Donald\'s personal capital and borrowing power is tied up in his 51% stock ownership. He knows that any offering of additional shares of stock will dilute his controlling interest because he won\'t be able to participate in such an issuance. But, Nina has money and would likely buy enough shares to gain control of Wichita. She then would dictate the company\'s future direction, even if it meant replacing Donald as president and CEO. The company already has considerable debt. Raising additional debt will be costly, will adversely affect Wichita\'s credit rating, and will increase the company\'s reported losses due to the growth in interest expense. Nina and the other minority stockholders express opposition to the assumption of additional debt, fearing the company will be pushed to the brink of bankruptcy. Wanting to maintain his control and to preserve the direction of â€œhisâ€ company, Donald is doing everything to avoid a stock issuance and is contemplating a large issuance of bonds, even if it means the bonds are issued with a high effectiveâ€“interest rate. Instructions Answer the following questions. Who are the stakeholders in this situation? What are the ethical issues in this case? What would you do if you were Donald? Solution a)Donald and nina are the stakeholders in this situation . b)Ethical issue involved in this case is to Raise additional funds by issue of stock or to raise additonal debts to meet fund requirement. If funds are raised through issue of stock ,Donald stock ownership will be diluted and when bonds are issued ,it will be costlier to a company to raise additional funds. c) Donald can either go for BOOTSTRAPPING where funds are raised by investing the retained earnings of a company and finding a means within a company. Also Donald can also suggest Right issue of shares where shares are offered to existing shareholders at concessional price (lower than market) so that his ownership is not diluted. .

Describe three of the following attack types in the Operation Security domain: man-in-the-middle, mail bombing, war-dialing, ping-of-death, teardrop, and slamming-and-cramming Solution The description of the attack types in the operation security domain is given below: 1) man-in-the-middle: In this type of attack, the intruder insert himself or insert any malicious code between the secure communication of two parties. This malicious code act as an third party, and its get the secure information that is being transfer between the two parties. Its third person or the intruder having access to the information send by both the parties involve in the communication. 2) mail bombing : Its refer to attack in which intruder try to send bulk of mails to the person\'s system, which may cause to disk full on persons system or even can crash the server, which is handling the mails. In this type of attack, the main aim is to crash the user\'s machine by fulling the disk space or can crash or stop the mail server. 3) War dialing: In this type of attack, hacker\'s uses the modem\'s to dial the range of numbers, for finding the computer machiner, servers and other devices. and after dialing they also get access to these type of devices. 4) Ping to death : Its a type of attack, in which the hacker send the incorrect ping packet to the user. There are various computer system which are designed not to handle the incorrect ping packets. Which results into system crash or system going into the abnormal state. 5) teardrop: Its a type of attack, in which the hacker sends the packets in incorrect way or in the fragmented way, that the end user is not able to reassemble these packets at their end, and results into the system crash and denial of service at user\'s end. 6)slamming-and-cramming: slamming refers to the activity in which hacker, switches the long distance calll carrier at user\'s phone, without its permission, its results into heavy bill at customer end. Cramming refers to the attack in which some extra bill is added into user\'s actual phone bill, and its keep on happening again and again .

Describes the concept of ADTS and illustrates the concept with three of the most common abstract data types. Solution An abstract data type is a set of values, some of which may be distinguished as constants, together with a collection of operations involving members of the set.The primary objective is to seperate the implementation of the abstract data types from their function.The program must know what the operations do. List,stack and queues are three fundamental data structures.When you declare a variable in a .NET application, it allocates some chunk of memory in the RAM. This memory has three things: the name of the variable, the data type of the variable, and the value of the variable.Depending on the data type, your variable is allocated that type of memory. There are two types of memory allocation: stack memory and heap memory Stack memory stores data types like int , double , Boolean etc. While heap stores data types like string and objects.Stack is used for static memory allocation and Heap for dynamic memory allocation, both stored in the computer\'s RAM .Variables allocated on the stack are stored directly to the memory and access to this memory is very fast.When a function or a method calls another function which in turns calls another function etc., the execution of all those functions remains suspended until the very last function returns its value. The stack is always reserved in a LIFO order.Variables allocated on the heap have their memory allocated at run time and accessing this memory is a bit slower, but the heap size is only limited by the size of virtual memory . Element of the heap have no dependencies with each other and can always be accessed randomly at any time. You can allocate a block at any time and free it at any time. This makes it much more complex to keep track of which parts of the heap are allocated or free at any given time. The Queue works like FIFO system , a first-in, first-out collection of Objects. Objects stored in a Queue are inserted at one end and removed from the other. The Queue provide additional insertion, extraction, and inspection operations. We can Enqueue (add) items in Queue and we can Dequeue (remove from Queue ) or we can Peek (that is we will get the reference of first item ) item from Queue. Queue accepts null reference as a valid value and allows duplicate elements. A list is a collection of items that can be accessed by index and provides functionality to search, sort and manipulate list items. This can store any data types to create a list.The List class can be used to create any type including a class. In this article, we will see how to create a list of a class with several properties. .

Describe, manage, and install Active Directory replication, federation services, and certificate services. Demonstrate the ability to plan an advanced AD, DHCP, and DNS solution. Describe and plan for configuring a domain and forest as well as configuring trusts. Use technology and information resources to research issues in advanced network infrastructure environments. Write clearly and concisely about advanced network infrastructure topics using proper writing mechanics and technical style conventions. Solution Active directory replication Replication is the process by which the changes that are made on one domain controller are synchronized with all other domain controllers in the domain or forest that store copies of the same information. Active Directory replication uses a connection topology that is created automatically, which makes optimal use of beneficial network connections and frees the administrators from having to make such decisions. Manage and install active directory replication Active Directory relies on site configuration in sequence to manage and optimize the process of replication. Active Directory make available automatic configuration of these settings in some cases as well as configure site-related information for network using Active Directory Sites and Services. Configurable information includes settings for site links, site link bridges, and bridgehead servers. Federation service: Active Directory Federation Services (AD Federation Services) is a feature of the Windows Server operating system. It uses a claims-based access-control authorization model to maintain application security and to implement federated identity and aims to reduce the complexity around password management and guest account provisioning. AD Federation Services builds upon this functionality to authenticate users on third-party systems. Certificate service Active Directory Certificate Services (AD CS) provides customizable services for issuing and managing public key certificates used in software security systems that employ public key technologies. AD CS include Secure/Multipurpose Internet Mail Extensions (S/MIME), secure wireless networks, virtual private networks (VPN), Internet Protocol security (IPsec), Encrypting File System (EFS), smart card logon, Secure Socket Layer/Transport Layer Security (SSL/TLS) and digital signatures. .

Describe the process to start and restart apache on CENTOS command line. Also describe how to have apache start automatically when the server is rebooted. Solution In order to stop or restart the Apache HTTP Server, you must send a signal to the running httpd processes. There are two ways to send the signals. First, you can use the unix kill command to directly send signals to the processes. You will notice many httpd executables running on your system, but you should not send signals to any of them except the parent, whose pid is in the PidFile. Start: Starting httpd using the apachectl control script sets the environmental variables in /etc/sysconfig/httpd and starts httpd. You can also set the environment variables using the init script. You can also start httpd using /sbin/service httpd start. This starts httpd but does not set the environment variables. If you are using the default Listen directive in httpd.conf, which is port 80, you will need to have root privileges to start the apache server. Restart: Signal: HUP apachectl -k restart Sending the HUP or restart signal to the parent causes it to kill off its children like in TERM, but the parent doesn\'t exit. It re-reads its configuration files, and re-opens any log files. Then it spawns a new set of children and continues serving hits. If you want your server to continue running after a system reboot, you should add a call to apachectl to your system startup files (typically rc.local or a file in an rc.N directory). This will start Apache as root. Before doing this ensure that your server is properly configured for security and access restrictions. The apachectl script is designed to act like a standard SysV init script; it can take the arguments start, restart, and stop and translate them into the appropriate signals to httpd. So you can often simply link apachectl into the appropriate init directory. But be sure to check the exact requirements of your system. .

Describe, in your own words, the mechanism for establishing a HTTPS connection. Solution HTTPS consists of communication over HTTP (Hypertext Transfer Protocol) with an encrypted layer such as Transport Layer Security (TSL) or Secure Sockets Layer (SSL). The connection between Client and Server using HTTPS is established by a handshake process which has 3 main phases namely Hello, Certificate exchange and key exchange. a) Hello- This is the first phase where the client sends a message ClientHello which contains all the necessary information such as various cipher suites, SSL version number etc. for the server to connect to the client via SSL. Then the server responds with a ServerHello message which contains similar information for client. b) Certificate Exchange â€“ Once the contact is established between the Server and the Client, the server has to prove its identity to the client using its SSL certificate. The SSL certificate contains various information such as name of the owner, the domain it is attached to, the certificateâ€™s public key, certificateâ€™s validity dates etc. The client then verifies the certificate whether it is a trusted certificate or it is verified and trusted by one of several Certificate Authorities (CAs) which client trusts. c) Key Exchange â€“ In this phase the exchange of encryption key is happened by the client and server using a symmetric algorithm which was already agreed during the Hello phase. The client generates a random key for the symmetric algorithm. It then encrypts the key using an algorithm (which was also agreed upon during the Hello phase) and the serverâ€™s public key from the SSL certificate. Client then sends this encrypted key to the server, where it is decrypted using the serverâ€™s private key. Once the client and server have verified each overâ€™s identity and have secretly agreed on a key to symmetrically encrypt the data that they are about to send each other, then the HTTP requests and responses can start flowing form one party to other in the form of a plaintext message with encryption. The other party using the key decrypt is while reading. .

Solution Commercial Service Airports are publicly owned airports that have at least 2,500 passenger boardings each calendar year and receive scheduled passenger service. Passenger boardings refer to revenue passenger boardings on an aircraft in service in air commerce whether or not in scheduled service. The definition also includes passengers who continue on an aircraft in international flight that stops at an airport in any of the 50 States for a non-traffic purpose, such as refueling or aircraft maintenance rather than passenger activity. Passenger boardings at airports that receive scheduled passenger service are also referred to as Enplanements. Nonprimary Commercial Service Airports are Commercial Service Airports that have at least 2,500 and no more than 10,000 passenger boardings each year. Primary Airports are Commercial Service Airports that have more than 10,000 passenger boardings each year. Hub categories for Primary Airports are defined as a percentage of total passenger boardings within the United States in the most current calendar year ending before the start of the current fiscal year. For example, calendar year 2014 data are used for fiscal year 2016 since the fiscal year began 9 months after the end of that calendar year. The table above depicts the formulae used for the definition of airport categories based on statutory provisions cited within the table, including Hub Type described in 49 USC 47102. Cargo Service Airports are airports that, in addition to any other air transportation services that may be available, are served by aircraft providing air transportation of only cargo with a total annual landed weight of more than 100 million pounds. \"Landed weight\" means the weight of aircraft transporting only cargo in intrastate, interstate, and foreign air transportation. An airport may be both a commercial service and a cargo service airport. Reliever Airports are airports designated by the FAA to relieve congestion at Commercial Service Airports and to provide improved general aviation access to the overall community. These may be publicly or privately-owned. General Aviation Airports are public-use airports that do not have scheduled service or have less than 2,500 annual passenger boardings (49 USC 47102(8)). Approximately 88 percent of airports included in the NPIAS are general aviation. .

Describe the major types of VPNs and technologies, protocols, and services used to deploy VPNs. Also describe the business benefits of VPNs. Solution A virtual private network (VPN) is a technology that creates an encrypted connection over a less secure network. The benefit of using a VPN is that it ensures the appropriate level of security to the connected systems when the underlying network infrastructure alone cannot provide it. The justification for using a VPN instead of a private network usually boils down to cost and feasibility: It is either not feasible to have a private network (e.g., for a traveling sales rep) or it is too costly to do so. The most common types of VPNs are remote-access VPNs and site-to-site VPNs A remote-access VPN uses a public telecommunication infrastructure like the Internet to provide remote users secure access to their organization\'s network. A VPN client on the remote user\'s computer or mobile device connects to a VPN gateway on the organization\'s network, which typically requires the device to authenticate its identity, then creates a network link back to the device that allows it to reach internal network resources (e.g., file servers, printers, intranets) as though it was on that network locally. A remote-access VPN usually relies on either IPsec or SSL to secure the connection, although SSL VPNs are often focused on supplying secure access to a single application rather than to the whole internal network. Some VPNs provide Layer 2access to the target network; these require a tunneling protocol like PPTP or L2TP running across the base IPsec connection. A site-to-site VPN uses a gateway device to connect the entire network in one location to the network in another, usually a small branch connecting to a data center. End-node devices in the remote location do not need VPN clients because the gateway handles the connection. Most site-to-site VPNs connecting over the Internet use IPsec. It is also common to use carrier MPLS clouds rather than the public Internet as the transport for site VPNs. Here, too, it is possible to have either Layer 3 connectivity (MPLS IP VPN) or Layer 2 (Virtual Private LAN Service, or VPLS) running across the base transport. VPNs can also be defined between specific computers, typically servers in separate data centers, when security requirements for their exchanges exceed what the enterprise network can deliver. Increasingly, enterprises also use VPNs in either remote-access mode or site-to-site mode to connect (or connect to) resources in a public infrastructure as a service environment. Newer hybrid-access scenarios put the VPN gateway itself in the cloud, with a secure link from the cloud service provider into the internal network. .

Describe the ethnic city and the benefit of ethnic communiti? (. I need 4 paragraphs please . Explain what you believe social justice meant to Progressive? ( 1 paragraph Solution 1ans) An â€˜ethnic groupâ€™ has been defined as a group that regards itself or is regarded by others as a distinct community by virtue of certain characteristics that will help to distinguish the group from the surrounding community. Ethnicity is considered to be shared characteristics such as culture, language, religion, and traditions, which contribute to a person or groupâ€™s identity. Ethnicity has been described as residing in: â€¢ The belief by members of a social group that they are culturally distinctive and different to outsiders; â€¢ Their willingness to find symbolic markers of that difference (food habits, religion, forms of dress, language) and to emphasized their significance â€¢ Their willingness to organize relationships with outsiders so that a kind of â€˜group boundaryâ€™ is preserved and reproduced This shows that ethnicity is not necessarily genetic. It also shows how someone might describe themselves by an ethnicity different to their birth identity if they reside for a considerable time in a different area and they decide to adopt the culture, symbols and relationships of their new community. It is worth noting that the Traveller Community is recognised as a distinct ethnic group in the UK and Northern Ireland, but only as a distinct cultural group in the Republic of Ireland. Ethnicity is also a preferential term to describe the difference between humans rather than â€˜raceâ€™. This is because race is a now a discredited term that divided all peoples based on the idea of skin colour and superiority. There is only one â€˜raceâ€™, the human race as we are essentially genetically identical. For example, there is no French â€˜raceâ€™ but the French people could be described as a separate ethnic group. Advantages Disadvantages 2ans) Progressivism is a term commonly applied to a variety of responses to the economic and social problems that arose as a result of urbanization and the rapid industrialization introduced to America in the 19th Century. Progressivism began as a social movement to cope with a variety of social needs and eventually evolved into a reform movement and greater political action. The early progressives rejected Social Darwinism. In other words, they were people who believed that the problems society faced (poverty, poor health, violence, greed, racism, class warfare) could best be addressed by providing good education, a safer environment, an efficient workplace and honest government. Progressives lived mainly in the cities, were college educated, and believed that government could be a tool for change. .

Describe the different types of qualitative analysis and indicate which is most persuasive. Solution A qualitative analysis or a research is based on the collection and analysis of non-numeric data like words or pictures. Qualitative methods have three distinct dimensions which are as follows: 1. Understanding Concept 2. Understanding People 3. Understanding Interaction Four major types of qualitative research are: 1. Phenomenology - The analysis of data is done by getting access to individuals life-worlds, which is actually their world of experience. This can be done by conducting in-depth interviews. In this analysis the commonalities across individuals are sought. Once the data is collected it will be analyzed and report will be prepared based on the collected data and understandings. 2. Ethonography - It is a analysis based on the study of a group of people based on their culture. People from same or similar culture share beliefs, customs, rituals, practices and language norms. This will be highly effective in analyzing data qualitatively. The data that are collected in this method of analysis are based on the cultural standards, insider\'s perspective, external and social scentific view. 3. Grounded Theory - Here the analysis is based on the theoretical approach. The major characteristics of grounded theory are Fit, Understanding, Generality and control. Theories provide explanation and they tell us how and why of any situiation. 4. Case Study - In this analysis the various cases are considered and in-depth analysis is performed to study the variations and deviations. In all the above steps Data coding and analysis takes place. Data Analysis is done in three different steps and they are: 1. Open Coding -Â Â Reading transcripts 2. Axial Coding - Organizing concepts 3. Selective Coding - Focusing on main ideas Phenomenology is the most pursuasive method of qualitative analysis since the data is sought directly from the individuals. Hence this can be relied upon thoroughly. .

Describe neo-evolution. What is it and what are its primary tenets? Provide an example of a technology that is altering or may alter human evolution. What are the potential benefits of this type of technology? What are the potential drawbacks? What are the moral and ethical implications of neo-evolution? Should we continue to pursue this form of technology? Why or why not? Solution oevolutionism , school of anthropology concerned with long-term culture change and with the similar patterns of development that may be seen in unrelated, widely separated cultures. It arose in the mid-20th century, and it addresses the relation between the long-term changes that are characteristic of human culture in general and the short-term, localized social and ecological adjustments that cause specific cultures to differ from one another as they adapt to their own unique environments. Further, neoevolutionists investigate the ways in which different cultures adapt to similar environments and examine the similarities and differences in the long-term historical trajectories of such groups. Because most neoevolutionists are interested in the environmental and technological adjustments of the groups they study, many are identified with the cultural ecological approach to ethnography, with the culture process approach to archaeology, and with the study of early and protohumans in biological anthropology. Neoevolutionary anthropological thought emerged in the 1940s, in the work of the American anthropologists Leslie A. White and Julian H. Steward and others. White hypothesized that cultures became more advanced as they became more efficient at harnessing energy and that technology and social organization were both influential in instigating such efficiencies. Steward, inspired by classifying the native cultures of North and South America, focused on the parallel developments of unrelated groups in similar environments; he discussed evolutionary change in terms of what he called â€œlevels of sociocultural integrationâ€ and â€œmultilinear evolution,â€ terms he used to distinguish neoevolution from earlier, unilineal theories of cultural evolution. In the years since Whiteâ€™s and Stewardâ€™s seminal work, neoevolutionary approaches have been variously accepted, challenged, rejected, and revised, and they continue to generate a lively controversy among those interested in long-term cultural and social change. .

Describe ip protocol security pros and cons. Solution IP Protocol Security: Internet Protocol Security ( IPsec ) is a protocol suite for secure Internet Protocol (IP) communications by authenticating and encrypting each IP packet of a communication session. IPsec can be used in protecting data flows between a pair of hosts ( host-to-host ), between a pair of security gateways ( network-to-network ), or between a security gateway and a host ( network-to-host ). Security architecture: Pros of IPsec: Â·Security at the Network Layer Level - Being based at the network level, this technology is completely invisible in its operation . The end users are never required to learn about it, and neither do they ever directly interact with it. This in itself is an added layer of security for the VPNs running on IPsec. Â·No Application Dependence - While SSL-/ SSH-/ PGP-based VPNs are application-dependent, IPsec-based VPNs do not need to worry about application dependence. Since the entire security system is implemented at the network level, there are no application compatibility issues. Cons of IPsec: Â·CPU Overhead - Having to perform encryption and decryption on the hundreds of megabytes of data flowing through the machines requires quite a bit of processing power, and this translates to higher processor loads . Â·Compatibility Issues - IPsec is a standardized solution today, and yet, some large software developers may not adhere to it, and may go ahead with standards of their own. As a result, this can lead to compatibility issues . Â·Broken Algorithms - Some of the security algorithms that are still being used in IPsec have already been cracked. This poses a huge security risk, especially if the network administrators unknowingly use those algorithms instead of newer, more complex ones that are already available. .

Describe core competencies and their relationship to operations management. Please provide an example for a manufacturing environment and a service environment. Solution core competency fullfills three key criteria: A core competency can take various forms, including technical/subject matter know-how, a reliable process and/or close relationships with customers and suppliers. It may also include product development or culture, such as employee dedication, best Human Resource Management (HRM), good market coverage, or kaizen or continuous improvement over time. Core competencies are particular strengths relative to other organizations in the industry, which provide the fundamental basis for the provision of added value. Core competencies reflect the collective learning of an organization and involve coordinating diverse production skills and integrating multiple streams of technologies. It includes communication, involvement, and a deep commitment to working across organizational boundaries, such as improving cross-functional teams within an organization to address boundaries and to overcome them. Few companies are likely to build world leadership in more than five or six fundamental competencies. As an example of core competencies, Walt Disney World Parks and Resorts has three main core competencies: core competencies their relationship to operations management Operations management is an area of management concerned with overseeing, designing, and controlling the process of production and redesigning business operations in the production of goods or services. It involves the responsibility of ensuring that business operations are efficient in terms of using as few resources as needed, and effective in terms of meeting customer requirements. Core competencies are the collective learning in the organization, especially how to coordinate diverse production skills and integrate multiple streams of technologies.It embodies an organization .

Describe in detail a man-in-the-middle attack on the Diffie-Hellman key-exchange protocol whereby the adversary ends up sharing a key k A with Alice and a different key k B with Bob, and Alice and Bob cannot detect that anything has gone wrong. What happens if Alice and Bob try to detect the presence of a man-in-the-middle adversary by sending each other (encrypted) questions that only the other party would know how to answer? Solution In man-in-the-middle attack, an opponent Eve intercepts Alice\'s public key K A and sends her own public key as K A to Bob. When Bob transmits his public key K B , Eve substitutes it with her own and sends it as K B to Alice. Eve and Alice thus agree on one shared key and Eve and Bob agree on another shared key. After this exchange, Eve simply decrypts any messages sent out by Alice or Bob, and then reads and possibly modifies them before re-encrypting with the appropriate key and transmitting them to the other party. This vulnerability is present because Diffie-Hellman key exchange does not authenticate the participants. The man-in-the-middle attack may be prevented by using digital signatures and other cryptographic schemes. Bob to encrypt a message so that only Alice will be able to decrypt it, with no prior communication between them other than Bob having trusted knowledge of Alice\'s public key. Alice\'s public key is g K A mod p, g,p. . To send her a message, Bob chooses a random K B and then sends Alice g K B mod p together with the message encrypted with ( g K A ) K B mod p symmetric key. Only Alice can determine the symmetric key and hence decrypt the message because only she has K A. .

Describe events that led to the signing of the Homeland Security Act 2002 into law on November 25, 2002. What was the intent of this Act and what department did it create? How did the Act change FEMAâ€™s emergency response role? Several agencies resisted efforts to be incorporated in the new department. Identify three such agencies and explain why they may have been reluctant to join. Do you agree? Solution Department of Homeland Security (DHS) was formed during the incorporation of all or part of 22 various federal departments into a united, incorporated Department. It was initiated to make the Americans safe. The President of America says to form a novel DHS, by considering all the departments into a single to safeguard the America under the name of DHS. It is the strategic plan applied by him after the terrorist attack in pennenslavia. The DHS mission is to keep the Americans safe from any of the attacks. Blue campaign and citizen corps involved in the Department of Homeland security. The Blue Campaign gives its support to the DHS and believe that every people has a right to have a freedom and then it combines with other NGOâ€™s, to fulfill its belief. The mission of Citizen Corps is to bind the people of Americans to enhance their knowledge with education, providing training centers, and volunteer service to make people strong and prepare them how to handle situations when they were troubles or attacks by other or some other natural disasters occurs. The Federal Emergency Management Agency (FEMA) is an organization of theUnited States Department of Homeland Security, initially created by Presidential Reorganization Plan No. 3 of 1978 and implemented by twoExecutive Orders on April 1, 1979.The goal is to organize the reply to a disasters that has happened in the US and then provide the funds to local and state government. The governer from that state that is where the disaster took place is the right person to intimate to the FEMA and to president .
