Analyze the security mechanisms needed to protect the DMS systems from both state employees
and users accessing over the internet:
Department of Management Services (DMS) has chosen to expand their applications and services
via TCP/IP and Internet access. DMS uses a widely used proprietary scheme: IBM's Systems
Network Architecture (SNA) which provides support for TCP/IP (Transmission Control
Protocol/Internet Protocol). SNA architecture is projected to remain important for some years to
come. Implementing standardized protocol architectures allow DMS ongoing communication with
suppliers, ... Show more content on Helpwriting.net ...
Thus, all distributed applications, including remote logon, client/server, email, file transfer, Web
access, and so on, can be secured (Stallings, 2009). Finally, Stallings (2009) has noted, "another
relatively general–purpose solution is to implement security just above TCP by using Secure
Sockets Layer (SSL) and the follow–on Internet standard Transport Layer Security (TLS). For full
generality, SSL, (TLS) could be provided as part of the underlying protocol suite and therefore be
transparent to applications. Alternatively, SSL can be embedded in specific packages.
Critique the transition process performed by the DMS in the case study. Then, recommend two (2)
alternatives to the IP Infrastructure or applications not already mentioned in the case study: By the
early 1990s, the Florida department of management services (DMS) had built up a large information
systems network that serve state government agencies in 10 regional sites and connected these to the
data center in Tallahassee. The network was based on the use of the proprietary systems network
architecture (SNA) from IBM and mainframe at the data center that housed most of the applications.
Although relatively happy with the SNA application and services by providing TCP/IP capability
and internet access. The goal was met in a remarkably short time. Over the course of 30 months,
DMS built a statewide TCP/IP network, began

An advantage of REST is its simplicity when compared to Simple Object Access Protocol SOAP,
which requires writing or using a provided server program and a client program. Roy Fielding
created the principles of REST architecture in the year 2000. REST has proved to be a popular
choice for implementing Web Services this is used by online retail giants Amazon.
An application or architecture considered REST–ful or REST–style is characterized by:
State and Functionality division categorically across resource
Use HTTP commands of GET, POST, PUT, or DELETE over the Internet. Every resource is
uniquely addressable using a uniform and minimal set of commands.
The protocol is often client/server.

Near Field Communication ( Nfc )
NFC Report Name Date Near–field communication (NFC) Near–field communication (NFC) is a
set of protocols that allow communication between two electronic devices. Most commonly this
technology is used for communication between portable devices like smartphones. Even though it is
a contact less system of communication, it requires that the devices are within 4 cm or 1.57 inch
distance from each other (Carter & Faulkner, 2015). Basically, this technology relies on creating a
low speed connection between the devices which has a very simple setting up procedure. It has
found application in a vast variety of applications, ranging from contact less payment from credit
and debit cards as well as the smartphone based payment techniques, to the social networking
applications as well, where media and contact information can be shared wirelessly between
devices. NFC technology has also found application for identity related documents and keycards.
Encoding and Encryptions The technology that allows contactless transactions, because of its
simplicity and effectiveness has become an integral part of people's daily usage. However, there are
many concerns regarding security that people have expressed about it, most of which are quite valid.

Security protocols are primarily & commonly used to protect communication via the web, VPNs
(Virtual Private Networks) and the transferring of files. This report will now go on to compare two
main security protocols – TLS & SSH. They will be compared in a way that takes into account both
the similarities and differences in approach and features and their relative advantages and
disadvantages. This information will then be backed up by examples where each protocol would be
preferred to the other in a certain situation along with my own personal reasoning based on the
research that has been carried out on my part.
What Is TLS?
TLS (Transport Layer Security) is the successor to another security protocol; SSL (Secure Sockets
Layer) which was originally developed by 'Netscape' (HowStuffWorks "SSL and TLS". 2014). It is a
cryptographic security protocol which was designed primarily to ensure communication security
across the internet. Communication security is achieved by the use of X.509 certificates and hence
asymmetric cryptography which allows the exchange of a symmetric key, which can then be used to
encrypt the data that is being transmitted between both parties involved in the communication. The
protocol is made up of two main layers; TLS Record Protocol and TLS Handshake Protocol. TLS

Business Intelligence ( Bi ) And Business Analytics
Business intelligence (BI) and business analytics (BA) (sometimes used interchangeably) has
revolutionized the way businesses use data and can be contrasted, for the purpose of this essay, in
the following way: BI is raw data that has been transformed into meaningful information that
provides historical, current, and predictive views of business operations and environment, and BA
uses data and statistical methods to provide actionable information for decision makers. BI explains
what is happening, identifies the issue, and provides decisions to be made and BA explains why an
issue is occurring, what will occur, and what actions need to be taken. At the forefront of BI/BA
technology is International Business Machines (IBM) with a very broad array of related products
and services. Among the more popular products are its flagship analytics product IBM Cognos and
its Predictive Customer Analytics. IBM's Cognos Analytics allows business and IT professionals to
prepare and distribute all types of business reports from all departments with an organization and
access pertinent information such as financial reports, sales trends, production yields, and inventory
on any device on an hourly basis. IBM also offers a Predictive Customer Intelligence solution, an

the disadvantages of this business model were: customers restricted by location, the need for larger
amounts of inventory, larger retail space, and more employees to cover customer–service. E–

The company evolved into the 3–rd party distribution market which allowed vendors to sell their
products through Amazon's web store and with Amazon handling the transactions for a per–sale
commission. This allowed for smaller vendors, who might not have the technological capabilities

technology offered. One–click shopping was invented as was point–to–point tracking, where the
customer could watch how the shipping of their package progressed. But because of the inherent
complexity of these on–line systems, bad coding practices, rapid evolution of technology, constant

Remote Access Business today never sleeps in large part to advances in technology. Because of this,
users often need access to sensitive company data outside the office which presents many security
challenges. Not only is the end user accessing your network resources and potentially sensitive data,
but they are many times doing so from a public network which the admin has no control over and is
open to others who may have malicious intent. These connections clearly need to be properly
secured in order provide end users secure network connections. To secure remote connections, a
virtual private network (VPN) will created using the Routing and Remote Access feature available
within Windows Server 2012 R2. This feature allows end users to create a secure connection to the
network by using Extensible Authentication Protocol–Transport Level Security (EAP–TLS) in
addition to smartcards for authentication purposes. Traffic will also be encrypted by using Layer
Two Tunneling Protocol over IPSEC (TechNet, 2016). To implement this configuration properly, the
certificate authority mentioned above will be used to provide certificates to the servers and clients to
authenticate and encrypt transmissions over public networks. The network firewall will be
configured to accept this traffic and direct it to the VPN server. This configuration will allow
secured remote connections to network resources for employees and end users.

Google enables encrypted connections to these services to prevent attackers to spy on the
communications done by the users. These encrypted connections are made secure using certificates
that are issued by authorized certificate authorities (CAs). But, these certificates are vulnerable to
attack. An attacker can get a fraudulent certificate for such services and replace the server certificate
by this fraud certificate. This enables them to use it maliciously to intercept the communication done
by a user and service. The user will be ignorant that the connection is compromised. Suppose
Mallory can obtain a fraudulent certificate for Google service (gmail.com) and a user Alice would
trust the certificate. Then Mallory can eavesdrop on the communication between Gmail and Alice in

Application For The Cloud Service Provider
Applications in today's world consume resources on a wide variety of scale, one application could
be CPU based while another could be network based which mean each application would saturate a
few resources and under–utilize a few. With cloud computing, Pay as you go enables you to pay
only for the utilized. For example, an application consumes only 50% of the processing power; you
need not pay for the entire set of machines and would only pay for the utilized rate and cloud
providers offer competitive prices today. To add to it operating costs like building space, power,
cooling, maintenance of servers and network will be on the cloud service provider. The installation,
upgrades and patches are easily done as cloud provider usually relies on virtual machines instead of
physical equipment. According to a study, in the year of 2000, 45% of IT budget was spent on
capital expenditure whereas only 6% of the resulting server capacity was utilized1. In this scenario,
in the next couple of years the cost of server maintenance would exceed the capital expenditure
invested with very less utilization ratio. Datacenters of large scales can reduce the economies and
time of computing to a large extent and also contribute to the Green IT initiative saving the

Advantages And Disadvantages Of Packet Sniffers
A packet sniffer can only capture packet information within a given subnet. So, it's not possible for a
malicious attacker to place a packet sniffer on their home ISP network and capture network traffic
from inside your corporate network. In order to do so, the packet sniffer needs to be running on a
computer that is inside the corporate network as well. However, if one machine on the internal
network becomes compromised through a Trojan or other security breach, the intruder could run a
packet sniffer from that machine and use the captured username and password information in order
to compromise other machines on the network. Packet sniffers are very hard to detect because they
are passive, which means the sit on background reading the network stream and never send out data.

Software Security Is The Biggest E Commerce Retailer
Introduction
Software security is a concept of engineering software and it goes on functioning appropriately
under malicious attack. Majority of technologies accept the significance of this undertaking, but
they require assistance in understanding how to confront it. Best practices for software security
leverage the sound software engineering practices that include thinking about the security primarily
in the software lifecycle, understanding and knowing common threats (inclusive of pitfalls and flaws
that are language based), design for security and subjecting every software artifact to comprehensive
objective testing and risk analyses.
Security is an extent of the ability of the system for protecting information and data from
unauthorized access however still giving access to systems and people that are authorized. Attack
can be seen as an action taken against a computer system having the intent of causing harm, to it and
this may take numerous forms. It may refer to attempts aimed at accessing services or data, or
modification of data, or might be an intention of denying services for legitimate users.

Because of this unguarded exchange, it is possible to build a metric for the identification of a
particular client, by capturing the data contained in the initial packet that the client sends to the
server when trying to determine the protocols for the TLS session. The nature of these initial packets
changes only infrequently, and a fingerprint can be built from their elements and then utilized in
order to recognize a particular client in a future session. The fields and data points that need to be
captured from this observance are: the active TLS version the client is using , the TLS version in the
client's record layer, the ciphers and algorithms that were chosen and applied, any compression
methods utilized in the communication, and the list of active extensions utilized by the client. This
combined data set is effectively changed only on a very rare basis for any particular client, and
offers far greater granularity than assessing cipher suites alone. Capturing the initial communication
between the client and server is an excellent method for fingerprinting TLS packets for several
reasons. First and foremost, it is possible to capture the initial TLS greeting packets with a high

models there are in use. There are four different cloud deployment models that are used in the cloud
computing environment. The four models are private cloud, public cloud, hybrid cloud and
community cloud. A private cloud can be owned or leased and managed by the organization or a
third party and exist at on–premises or off–premises. A public cloud is an infrastructure is provided

Defining Firewalls and VPNs
What is a firewall and how does it work?
Many internet users are concerned about internet safety. A way to combat potential security breaches
is to use a firewall. A firewall can be a hardware device or a program and it is used to filter any
information that comes through any internet connection to your private network or computer system.
Harmful information can be flagged by the firewall program and not be allowed to continue through.
Firewalls use up to three different ways to control the information coming into and out of the
network. The first method is called packet filtering. Packets are little manageable block of
information that are then scrutinized through a set of filters. The ones that make it past the filters are
sent along their way and anything else is immediately discarded. The next method is called proxy
service which allows the firewall to retrieve requested information and send it to its destination. The
last method is called stateful inspection or "stateful filtering", which is more like packet filtering,
only it doesn't examine the whole packet (ISA, 2007). This method only examines certain parts of
the individual packets and then compares it to a database of trusted information. A firewall can also
be customized to block certain IP addresses and domain names and be configured to obey certain
protocols. There are many different types of protocols depending on what it is protecting. For

Network Security Concepts Essay
Network Security Concepts
File security falls into two categories, encryption and access. Access to files can mean physical
access to a computer with unsecured files or access via user permissions or privileges in the form of
access control lists (ACLs) (Strengthen Your Users' File Security, 2003). The files kept on a server
with NTFS storage can be locked to prevent anyone who does not have the correct permissions from
opening them. This is secure but can be bypassed with physical access to an open computer and
should not be used for sensitive information. The other method of securing files is by encrypting the
information in the files using an Encrypting File System (EFS), which employs public key
encryption privileges (Strengthen ... Show more content on Helpwriting.net ...
Secret and private keys are very similar and are often used interchangeably. The difference is that
secret keys are used for both encryption and decryption, while a private key is part of the
public/private key system and is used only for decryption (Cryptography, 2005). In both cases, the
key may be known only to a single person or a limited group of people in order to keep the key
secure.
Public–Key Infrastructure (PKI) is a method of verifying users on a network, while a digital
certificate is a reference from a neutral company that confirms the identity of an internet site (Shay,
2004, p. 321) and (Tomsho, G., Tittel, E. Johnson, D., 2004, P. 378). The digital certificate is issued
by a Certificate Authority (CA) such as Verisign, and a registration authority (RA) that acts as a
reference to identify an entity to a user of the website, and uses a directory that holds the certificate
and can revoke a company's digital status. The PKI technology is at the core of the digital
certificates used in almost all transactions on the internet. The PKI uses a cryptographic key pair,
one of which is public and one which is private, to authenticate the owner of the certificate (PKI,
2002).

Encryption
Encryption refers to a technique that facilitate the storage, transmission of information in a format
that is unreadable to unintended audience. Unintended audience in this case may be hackers,
sniffers, malwares e.t.c.the technique has been widely used to curb phishing in the current network
security landscape.
There are two fundamental techniques used in encrypting data: i.e. symmetric encryption (also
referred to as secret key encryption) and asymmetric encryption (also referred to as public key
encryption.)
Symmetric Encryption/Secret Key Encryption.
Symmetric encryption is the earliest and widely popular encryption technique. This technique uses a
secret key which can be a string of words, numbers which are randomly selected to effect
confidentiality. The secret Key is applied on the original message to change the content into a
cipher. The modification of the message to the cipher might be a simple reordering of the message
letter sequence to complex alterations. With the help of the secret key the sender and the recipient
can encrypt and decrypt messages respectively.
Symmetric key encryption therefore uses an identical key to encrypt and decrypt information. Due
to its simplicity it is faster as compared to asymmetric encryption with the length of keys critical to
the encryption security .NIST recommends that the

With the growth of the internet comes a great deal of electronic commerce, neatly and commonly
referred to as E–Commerce. This concept is a fast growing industry that allows its participants to
buy or sell products and services to each other using electronic devices via the Internet. With this
increasingly huge industry comes a danger of security among its users. It is quite a concern to the
general public that they may have their personal and financial information leaked through the
internet from security threats. To counteract these threats, we must not overlook a few fundamental
elements of transaction security, typically generalized as:
– confidentiality
– integrity
– authentication
– availability
– non–repudiation
– authorization
Confidentiality is an element defined by the protection of a user's information from other parties
than the recipient. Integrity enables the recipient to ensure that the information provided to them by
any sender is correct and accurate. This element is usually confused with confidentiality because it
is often involved in the same technologies as confidentiality. Authentication is the confirmation of a
user, typically to ensure that they or their data is authentic, i.e. safe. Availability, usually associated
with online stores, ensure that certain information – or in the case of online stores; that products or

both business and individual communications leading to the expansion of e–mail and e–commerce.
As a matter of fact, studies indicate that most of the internet communication content is e–mail
content. The result of this is the continuing demand concerning security and privacy in electronic
communication. The call and want for privacy and security has led to the arrival of proposals for
security that are discussed in the following contents of this paper. HTTP, also known as Hypertext
Transfer Protocol, designates how information is transferred between client and server over the Web.
The credit for the invention of the first HTTP is given to Tim Berners–Lee and the members of his
team in 1989 (Berners–Lee). The first HTTP only had a single method called GET, which requested
a single page from a server (Berners–Lee). Today, HTTP is the protocol allowing text, multimedia,
etc. to be downloaded from an HTTP server. HTTP determines what actions can be requested by
clients and how servers should handle the requests. HTTP clients make requests to servers running
HTTP web servers. For determining what page should be downloaded, HTTP employs a uniform
resource locator (URL) from a remote server. The URL comprises of the kind of request, for
instance, http://, the name of the server being contacted (for example, ysu.edu), and by choice the

network. VPN systems may be classified by the protocols used to tunnel the traffic, the tunnel 's
termination point location, whether they offer site–to–site or remote–access connectivity, the levels
of security served or the OSI layer they present to the connecting network.
Therefore, in order to prevent exposure of confidential information, VPNs generally allow only

timed out rather than being revoked? If strict checking is enabled and an attacker can prevent
responses from a certificate server than the users are denied from accessing that website, allowing
the attack to shut traffic off from the targeted server. What can browser companies do to enforce a

of devices (information sensing devices) exchanging information and interacting with each other via
the Internet and within the boundaries of certain protocols. We can thus characterize IoT as an

DMS uses a widely used proprietary scheme: IBM's Systems Network Architecture (SNA) which provides support for TCP/IP (Transmission Control Protocol/Internet Protocol). SNA architecture is projected to remain important for some years to come. Implementing standardized protocol architectures allow DMS ongoing communication with suppliers, ...

Finally, Stallings (2009) has noted, "another relatively general–purpose solution is to implement security just above TCP by using Secure Sockets Layer (SSL) and the follow–on Internet standard Transport Layer Security (TLS). For full generality, SSL, (TLS) could be provided as part of the underlying protocol suite and therefore be transparent to applications. Alternatively, SSL can be embedded in specific packages. Critique the transition process performed by the DMS in the case study. Then, recommend two (2) alternatives to the IP Infrastructure or applications not already mentioned in the case study: By the early 1990s, the Florida department of management services (DMS) had built up a large information systems network that serve state government agencies in 10 regional sites and connected these to the data center in Tallahassee. The network was based on the use of the proprietary systems network architecture (SNA) from IBM and mainframe at the data center that housed most of the applications. Although relatively happy with the SNA application and services by providing TCP/IP capability and internet access. The goal was met in a remarkably short time.

Near Field Communication ( Nfc ) NFC Report Name Date Near–field communication (NFC) Near–field communication (NFC) is a set of protocols that allow communication between two electronic devices. Most commonly this technology is used for communication between portable devices like smartphones. Even though it is a contact less system of communication, it requires that the devices are within 4 cm or 1.57 inch distance from each other (Carter & Faulkner, 2015). Basically, this technology relies on creating a low speed connection between the devices which has a very simple setting up procedure. It has found application in a vast variety of applications, ranging from contact less payment from credit and debit cards as well as the smartphone based payment techniques, to the social networking applications as well, where media and contact information can be shared wirelessly between devices. NFC technology has also found application for identity related documents and keycards. Encoding and Encryptions The technology that allows contactless transactions, because of its simplicity and effectiveness has become an integral part of people's daily usage. However, there are many concerns regarding security that people have expressed about it, most of which are quite valid. For example, one of the common application of NFC technology is its ability to make purchases through different credit and debit card accounts, very simply through one's smartphone.

Business Intelligence ( Bi ) And Business Analytics Business intelligence (BI) and business analytics (BA) (sometimes used interchangeably) has revolutionized the way businesses use data and can be contrasted, for the purpose of this essay, in the following way: BI is raw data that has been transformed into meaningful information that provides historical, current, and predictive views of business operations and environment, and BA uses data and statistical methods to provide actionable information for decision makers. BI explains what is happening, identifies the issue, and provides decisions to be made and BA explains why an issue is occurring, what will occur, and what actions need to be taken. At the forefront of BI/BA technology is International Business Machines (IBM) with a very broad array of related products and services. Among the more popular products are its flagship analytics product IBM Cognos and its Predictive Customer Analytics. IBM's Cognos Analytics allows business and IT professionals to prepare and distribute all types of business reports from all departments with an organization and access pertinent information such as financial reports, sales trends, production yields, and inventory on any device on an hourly basis. IBM also offers a Predictive Customer Intelligence solution, an integrated software which uses automation to acquire customer information such as buying behavior, web activity, and social media presence to model and "score" costumer behavior and provide customized actions so that a business ...

Businesses, before the creation of the web, were typically at a physical location where customers could come, browse, try–on, and purchase goods and services. Some of the disadvantages of this business model were: customers restricted by location, the need for larger amounts of inventory, larger retail space, and more employees to cover customer–service. E– commerce began with the advent of the Internet and started as billboards for information and advertisement purposes. Then as technology developed through the early 1980s, it grew into e–mail purchasing (Compuserve). From there, the World Wide Web, internet browsers ... Show more content on Helpwriting.net ... The company evolved into the 3–rd party distribution market which allowed vendors to sell their products through Amazon's web store and with Amazon handling the transactions for a per–sale commission. This allowed for smaller vendors, who might not have the technological capabilities and expertise to sell their products over the web, to take advantage of the many advantages this new technology offered.

Because of this, users often need access to sensitive company data outside the office which presents many security challenges. Not only is the end user accessing your network resources and potentially sensitive data, but they are many times doing so from a public network which the admin has no control over and is open to others who may have malicious intent. These connections clearly need to be properly secured in order provide end users secure network connections. To secure remote connections, a virtual private network (VPN) will created using the Routing and Remote Access feature available within Windows Server 2012 R2. This feature allows end users to create a secure connection to the network by using Extensible Authentication Protocol–Transport Level Security (EAP–TLS) in addition to smartcards for authentication purposes. Traffic will also be encrypted by using Layer Two Tunneling Protocol over IPSEC (TechNet, 2016). To implement this configuration properly, the certificate authority mentioned above will be used to provide certificates to the servers and clients to authenticate and encrypt transmissions over public networks.

With cloud computing, Pay as you go enables you to pay only for the utilized. For example, an application consumes only 50% of the processing power; you need not pay for the entire set of machines and would only pay for the utilized rate and cloud providers offer competitive prices today. To add to it operating costs like building space, power, cooling, maintenance of servers and network will be on the cloud service provider. The installation, upgrades and patches are easily done as cloud provider usually relies on virtual machines instead of physical equipment. According to a study, in the year of 2000, 45% of IT budget was spent on capital expenditure whereas only 6% of the resulting server capacity was utilized1. In this scenario, in the next couple of years the cost of server maintenance would exceed the capital expenditure invested with very less utilization ratio.

So, it's not possible for a malicious attacker to place a packet sniffer on their home ISP network and capture network traffic from inside your corporate network. In order to do so, the packet sniffer needs to be running on a computer that is inside the corporate network as well. However, if one machine on the internal network becomes compromised through a Trojan or other security breach, the intruder could run a packet sniffer from that machine and use the captured username and password information in order to compromise other machines on the network.

Because of this unguarded exchange, it is possible to build a metric for the identification of a particular client, by capturing the data contained in the initial packet that the client sends to the server when trying to determine the protocols for the TLS session. The nature of these initial packets changes only infrequently, and a fingerprint can be built from their elements and then utilized in order to recognize a particular client in a future session. The fields and data points that need to be captured from this observance are: the active TLS version the client is using , the TLS version in the client's record layer, the ciphers and algorithms that were chosen and applied, any compression methods utilized in the communication, and the list of active extensions utilized by the client. This combined data set is effectively changed only on a very rare basis for any particular client, and offers far greater granularity than assessing cipher suites alone. Capturing the initial communication between the client and server is an excellent method for fingerprinting TLS packets for several reasons.

A way to combat potential security breaches is to use a firewall. A firewall can be a hardware device or a program and it is used to filter any information that comes through any internet connection to your private network or computer system. Harmful information can be flagged by the firewall program and not be allowed to continue through. Firewalls use up to three different ways to control the information coming into and out of the network. The first method is called packet filtering. Packets are little manageable block of information that are then scrutinized through a set of filters. The ones that make it past the filters are sent along their way and anything else is immediately discarded. The next method is called proxy service which allows the firewall to retrieve requested information and send it to its destination. The last method is called stateful inspection or "stateful filtering", which is more like packet filtering, only it doesn't examine the whole packet (ISA, 2007). This method only examines certain parts of the individual packets and then compares it to a database of trusted information. A firewall can also be customized to block certain IP addresses and domain names and be configured to obey certain protocols.

The files kept on a server with NTFS storage can be locked to prevent anyone who does not have the correct permissions from opening them. This is secure but can be bypassed with physical access to an open computer and should not be used for sensitive information.

The difference is that secret keys are used for both encryption and decryption, while a private key is part of the public/private key system and is used only for decryption (Cryptography, 2005). In both cases, the key may be known only to a single person or a limited group of people in order to keep the key secure. Public–Key Infrastructure (PKI) is a method of verifying users on a network, while a digital certificate is a reference from a neutral company that confirms the identity of an internet site (Shay, 2004, p. 321) and (Tomsho, G., Tittel, E. Johnson, D., 2004, P. 378). The digital certificate is issued by a Certificate Authority (CA) such as Verisign, and a registration authority (RA) that acts as a reference to identify an entity to a user of the website, and uses a directory that holds the certificate and can revoke a company's digital status. The PKI technology is at the core of the digital certificates used in almost all transactions on the internet.

There are two fundamental techniques used in encrypting data: i.e. symmetric encryption (also referred to as secret key encryption) and asymmetric encryption (also referred to as public key encryption.) Symmetric Encryption/Secret Key Encryption. Symmetric encryption is the earliest and widely popular encryption technique. This technique uses a secret key which can be a string of words, numbers which are randomly selected to effect confidentiality. The secret Key is applied on the original message to change the content into a cipher. The modification of the message to the cipher might be a simple reordering of the message letter sequence to complex alterations. With the help of the secret key the sender and the recipient can encrypt and decrypt messages respectively. Symmetric key encryption therefore uses an identical key to encrypt and decrypt information.

E Commerce Security Threats And The Solutions Essay During the early 1960's, E–Commerce businesses conducted electronic transactions via primitive computer networks" but the way these transactions were exchanged provided little to no security(34).This made online transactions on WWW(World Wide Web), not reliable and unsecured making consumers eager to not take the chance of risking their information, on an unprotected system. During the early 1960's came "Electronic Data Interchange(EDI). EDI replaced traditional mailing and faxing of documents with a digital transfer of data from one computer to another". (35)This was the first step toward the E–Commerce that is present today.Then the influential SSL protocol would come to be which helped to improve the state of security on the WWW. This led to more protocols being introduced, leading to other detrimental protocols such as (3D Secure, TLS, SET). These protocols, that were just mentioned are still widely used today. This paper will go over the threats and the solutions of E–Commerce security. E–Commerce security threats according to "FindLaw UK, major threats to E–Commerce can be grouped into two categories, malicious and accidental threats".(34) The first threat gone over will be malicious threats which "include hackers attempting to penetrate a system and steal sensitive data, burglars stealing a laptop that has sensitive data on it and impostors posing as legitimate users and then copying website information".

Transfer Protocol : The Amazing Development Of The Internet Hypertext Transfer Protocol The incredible development of the internet has begun a booming of both business and individual communications leading to the expansion of e–mail and e–commerce. As a matter of fact, studies indicate that most of the internet communication content is e–mail content. The result of this is the continuing demand concerning security and privacy in electronic communication. The call and want for privacy and security has led to the arrival of proposals for security that are discussed in the following contents of this paper. HTTP, also known as Hypertext Transfer Protocol, designates how information is transferred between client and server over the Web. The credit for the invention of the first HTTP is given to Tim Berners–Lee and the members of his team in 1989 (Berners–Lee). The first HTTP only had a single method called GET, which requested a single page from a server (Berners–Lee). Today, HTTP is the protocol allowing text, multimedia, etc. to be downloaded from an HTTP server. HTTP determines what actions can be requested by clients and how servers should handle the requests. HTTP clients make requests to servers running HTTP web servers. For determining what page should be downloaded, HTTP employs a uniform resource locator (URL) from a remote server. The URL comprises of the kind of request, for instance, http://, the name of the server being contacted (for example, ysu.edu), and by choice the page being requested, (for example, /records). In ...

In a corporate setting, remote–access VPNs allow employees to access their company 's intranet from home or while traveling away from the office, and site–to–site VPNs allow staff member in geographically disparate offices to share one cohesive virtual network. A VPN also be used to interconnect two similar networks over a dissimilar middle network. VPN systems may be classified by the protocols used to tunnel the traffic, the tunnel 's termination point location, whether they offer site–to–site or remote–access connectivity, the levels of security served or the OSI layer they present to the connecting network. Therefore, in order to prevent exposure of confidential information, VPNs generally allow only verified remote access and make use of encryption techniques. VPNs provide security by the use of tunneling protocols and through security procedures such as encryption. The VPN security model give confidentiality such that even if the network traffic is sniffed at the packet, an attacker would only see encrypted data, sender authentication to prevent unauthorized users from accessing the VPN and message integrity to detect any occurence of manipulating with transmitted messages Secure VPN protocols include the following; Internet Protocol Security ...

Data Networking Assignment No: 2 Ans 1.Peer to peer communication provides reliable connection, all the resources are available with its users, inexpensive and is more robust as compared to the client–server model which is why most applications use this type of communication. However, certain applications instant messaging, e– mailing and video calling prefer client–server model to perform certain functions for the reasons that follows:  Client–server model is centralized which means all the files that are stored in the same place and can be easily administered.  The servers can be accessed remotely making its accessibility easier  The peers don't need any storage space as the server keeps all the resources and information like peer to ...

Ans 2.No, the immediate response will not be sent to the new IP address. When a user access www.google .com the DNS resolvers through which the website is accessed will cache the information like the IP address for a particular TTL time which could be few hours. Now, when changes are made, the DNS resolver all over the world that has not accessed www.google.com which is very rare will get immediately updated but the ones that have the information cached will not get updated till the TTL time is over. Hence, the web–cache server will send the information with the old IP of the website to the user who is accessing the DNS server that has the information cached and once the TTL time is over the user will be able to access the website with the new IP address(167.45.45.46). When a domain name resolving is done, the first place the PC will look into is the root name server( root NS). Ans 3. a) TCP and SSL Transmission Control Protocol (TCP) Secure Socket Layer (SSL)

Revoking certificates provides the Internet companies the ability to tell users that they have changed their security certificates. This research will introduce the inherent problem of an outdated certificate revocation system. This research will follow the mixed methods approach and consult many different types of research documents, tests, and discussions. This research will also document the level of knowledge that IT staff have when understanding certificate revocation. Some of the finding found during the initial research of certificate revocation found that there are better ways to use certificate revocation and that many browser companies ... Show more content on Helpwriting.net ... These companies have neglected to enforce by default SSL/TLS certificate revocation checking. By doing this, these companies have put their users at risk of phishing scams and/or man–in–the– middle attacks. Although users can change the certification revocation check settings, many users do understand the risk. Research conducted on this topic is just recently been released (within the last couple years). Questions still come up and my research project will attempt to answer these questions: Strict enforcement of certificate revocation can be set within browser, but even the most technical person may not be able to find and set these settings. Once the strict setting are set, what will the browser do if a certificate check times out and how will a user know that the certificate timed out rather than being revoked? If strict checking is enabled and an attacker can prevent responses from a certificate server than the users are denied from accessing that website, allowing the attack to shut traffic off from the targeted server. What can browser companies do to enforce a stricter certificate revocation check process? These questions will provide good data representing the inherent problem with web browsers and checking revoked certificates. This research project will focus on a mixed method, using qualitative and quantitative methods to gather and compare data. This research will include data gathered from other research, ...

SCOPE This era of computing and communication will extend beyond the realm of the traditional desktops, laptops and even mobile devices. The Internet of Things aims to extend the Internet services into the real world day to day objects. Internet of Things is essentially an intelligent network of a wide array of devices (information sensing devices) exchanging information and interacting with each other via the Internet and within the boundaries of certain protocols. We can thus characterize IoT as an ecosystem of connected people, objects and services, enabled by a pervasive and transparent technology designed to improve our quality of life. Internet of Things (IoT) can be envisaged as the single greatest technological wave in the information industry after the magnanimous Internet. According to Garter's technology cycle curve, the interest in IoT reached its peak in 2014 and ranks second in the top technological trends that would dominate in 2015 [1]. Even though the IoT trend seems pervasive, unified and seamless, there are still several factors that need to be taken care of before the actual deployment of a full–fledged IoT network. The Internet of Things currently lacks in theory, structure and standards that integrate the Internet with the real world sensing devices. Some of these factors include the provisioning low powered nodes, identification and locating the devices and being able to provide secure communication between them, distributed intelligence among many ...
