Remote Access And Secured VPN Connections Using EAP-TLS Authentication

Remote Access And Using Extensible Authentication Protocol...
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.

IPsec and VPN
IPSec
Internet Protocol Security (IPsec) is a set of protocol for establishment of securing Internet Protocol (IP) communications. Safety on data was
established through process of authentication and encryption of each IP packet in every communication session. At the beginning of the session,
mutual authentication between agents will established and cryptographic keys to be used will arbitrated during the session. IPsec can be applied in
protecting data flows not only between pair of hosts and pair of security gateway but also for between a security gateway and a host.
IPsec provided end–to–end security in the Internet Layer of the Internet Protocol Suite. It is different to other Internet security systems which is being

VPNs can be either remote–access or site–to–site. 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

The Internet And Its Effects On The World
The Internet has grown massively in the last six decades, making it one of the biggest inventions of humanity so far. I would take it a step further and
call it a necessity for todays people since most use it for a considerable amount of time everyday. Tedious and everyday tasks have been revamped to fit
the digital concept so that anyone can accomplish them from the comfort of their chair. Internet banking, e–commercing, socialising and paying the
bills are only a fraction of everyday things you can do online. Such activities involve sensitive data that need to be relayed securely over the network
and this happens with the help of OpenSSL. OpenSSL has been widely used in the last couple of years but only recently researchers found a crucial
bug in the code which shook the internet community and made everyone question the stability of open–source projects. KEYWORDS SSL; TLS;
OpenSSL; Heartbeat; Heartbleed; Validation; Certificates 1.INTRODUCTION It's evident that technology has massively evolved over the last
century, bringing new services on the table, such as communicating with people all over the world, ecommercing or generally doing things that
would take a lot of time with the press of just a few buttons. A new world unfolded since tons of information was being shared on the Internet. That,
led to the need for data encryption and it didn't take long for cryptographic protocols to be created, obfuscating data so that no eavesdropper would be

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

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).
In each of the layers of the OSI model, there are security risks that exist and are developing now, and

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:
пЃ¶Client–server model is centralized which means all the files that are stored in the same place and can be easily administered.

пЃ¶If about ten computers are connected at a time, then the quality of the communication deteriorates.
пЃ¶Back–up and recovery of every workstation connected in the system makes it tedious.
пЃ¶Full–time system administrator is required.
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).

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 asHypertext 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

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 environment. Cloud also offers potential benefits like
scalability where adding additional resources can be done in matter of hours and also eliminates the need for huge capital expenditure which enables
startups access to large

protocol originally created by a team at Netscape for secure transactions on early websites (although similar to SSL, TLS is different enough for them
to not work together). TLS will create a "tunnel" that is an established connection between source and destination, through which all packet data AND
packet headers are encrypted. However, before TLS gets involved, Dubh's source machine must first establish a reliable transport protocol with which
to communicate with the destination. In this case, we will (safely) assume that we are using Transmission Control Protocol (TCP) to establish this

With the evolution of technology, the number of hacking incidents and data breaches has been increased. Hacking indicates to utilizing computers to
perpetrate fraudulent actions such as security attack, or stealing confidential data. Hackers identify and exploit vulnerabilities in computer systems or
networks to gain access to the system. According to an article published by the BBC, hacking incidents cost small and big organization billions of
pounds over the years. There are two types of hacking which are ethical hacking and unethical hacking. The objective of ethical hacking is to recognize
system vulnerabilities in order to develop security. Ethical hackers aim to steal information or destroy other systems through performing malicious
attacks. The main purpose of this case study report is to examine the hacking case of Yahoo! that was occurred in 2014, as well as recommendations

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,

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".(34)Another

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.

environment and include a brief comparison of different approaches.
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
services – are ready and in stock before a transaction takes

It is the layer responsible for packet determination and IP addressing. At this layer, I recommend using IPSec. It can block and filter data received
and sent to the Intranet file server based on IP address and port number. The web administrator can block traffic from all ports except port 80
(HTTP) and port 443 (HTTPS). A security policy needs to be added to the Active Directory to block traffic to the entire network. The security policy
should only allow access to the Intranet file server. IPSec also protects the transport layer. It can be used with Kerberos to authenticate the client/server
session. An IPSec certificate is used to verify the routers' identity. IPSec provides encryption for data exchanges between the router and client machine.

The Impact Of Internet On The Information Industry After...
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

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

Install OpenVPN onto Windows Server 2012r2 into the H1 Country Club Network for Remote Access
OpenVPN is an open–source software application that implements virtual private network (VPN) techniques for creating secure point–to–point or
site–to–site connections and remote access facilities. OpenVPN allows authentication using certificates or username/password. OpenVPN can work in
two different modes regarding encryption. It can use static encryption or Public Key Infrastructure (PKI). The advantage of static encryption is that it
is very easy to configure. The disadvantage of this type setup is that if your encryption key is compromised, all VPN data can easily be decrypted.
The PKI mode resolves many of the issues static encryption has. It ... Show more content on Helpwriting.net ...

Risk Management or Assessment To lessen the exposure of the corporate network to outside sources, there are many matters to consider. Areas of
concern with the VPN client that should be addressed include: the potential hazards of the "always connected" nature of broadband Internet
connections, installation of personal firewalls, antivirus software, and the remote PC itself. Analysis of the client PC begins with the PC itself. It is
recommended that security policy require the VPN host to be company issued equipment, rather than using the existing user's personal property. This
eliminates problems associated with mixing business and personal information. When under company ownership it is easier to require the end user to
comply with policy, and insist the PC be used only for business–related purposes. As the hardware is company–owned, users will not be given
administrator account rights on their desktop machines. Controlling user activity as well as checking and maintaining desktop integrity is very
difficult (if not impossible) when users have complete control through administrator rights. Company provided hardware also serves to minimize
management issues, as the computer should remain relatively static – with no unauthorized software installations, end–user configuration changes or
device conflicts to troubleshoot, support calls are reduced. In addition to

In this paper, creator proposed another strategy to influence system coding to decrease the vitality devoured by information encryption in MANETs. To
this end, creator proposed P–Coding, a lightweight encryption plan to give privacy to network–coded MANETs in a vitality effective way. The
fundamental thought of P–Coding is to let the source haphazardly permute the images of every parcel, before performing system coding operations.
Without knowing the stage, busybodies can 't find coding vectors for right deciphering, and in this manner can 't get any significant data and shows that
because of its lightweight nature, P–Coding brings about negligible vitality utilization contrasted with other encryption plans. Yet, in this paper, for

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. However, this feature, even

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 example, File Transfer protocol is

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 will be most commonly recognised when 'https'
is noticed in

HTTPS is important as it helps reduce the chances of "hackers snooping or trying to seize and access your customers' data" as it moves between the
internet server and your computer or vice versa.
With HTTPS it can be guaranteed that the site will encrypt their information for that extra level of security.
It shouldn't come as a surprise that Google prefers sites that are trusted and certified.
Considering the benefits of HTTPS and to make the internet a secure place Google has announced that going HTTPS – adding a SSL certificate on
your site – will give you a ranking boost.
Google has also updated Google Webmaster Tools to better handle HTTPS sites and the reporting on them.

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 spite of the encrypted communication. Mallory will pretend to be Gmail while communicating with Alice,
and she will pretend to be Alice while communicating with Gmail. Mallory can get all the private information of Alice including his username and
password. Mallory will use that username and password in talking to Gmail. Gmail and Alice think they are communicating directly with each other
through an encrypted connection but Mallory is the man in the middle. For this incidence, the government of Iran is Mallory, intercepting every

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.

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. So unless we know it's there we can't find it. One of the major drawbacks of packet sniffers is if
they can't understand data its junk. So the best way is to make data encrypted. But there are ... Show more content on Helpwriting.net ...

By sniffing a single wireless network, an intruder can access all the incoming and outgoing traffic over that wireless network resulting in heavy
loss of confidential data to an organization. If any intruder able to crack firewall and he will be able to access wireless network's internal network
and can read all the confidential data and also can inject malicious packets in the network so as to route the packets to some other destinations. There
is large number of tools available in the market through which a wireless network[1] can be cracked and sniffed such as: 802.11 wireless network
detector named Kismet, which is a wireless LAN detector named NetStumbler which uses 802.11b and WireShark for analyzing a network.
In order to secure a wireless network from intruders several measures has to be taken care while implementing wireless network within the
organization.Encryption algorithms are used to encrypt data over wireless network so that network cannot be easily read by the attackers. There are
several authentication techniques that can be implemented to secure data over wireless networks such as: biometric technique, OTP method and

A research project that synthesizes your knowledge of encryption, keys, and virtual private networks. Write a 5–7 page report on your findings.
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

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

Data location and data segregation are of importance in the cloud, given the disparate physical location of shared computing resources. It is a
possibility that cloud users be under statutory, regulatory or contractual obligations to ensure that data is held and managed in a certain way. To
understand where the data is stored in the cloud, a person must what type of cloud deployment 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 to many customers is managed by a third party and exist beyond the company firewall, examples would be
Microsoft Azure and Google App Engine. A hybrid cloud is a composition of two or more cloud deployment models, which links data in such a way
that the data transfer takes place between them without affecting each other. An example of a hybrid cloud would be Amazon Web Services (ABS).
The community cloud is a model that is shared by several organizations for a shared cause and may be managed by them or a third–party service
provider and rarely offered cloud model. The cloud environment operating according to this model may exist locally or remotely. An example of a

Virtual Private Network (VPN) comes to my sight by chance due to China's great firewall blocked my access to Gmail when I stayed in China last
summer. To visit the blocked websites, one of solutions is using VPN technology.
VPN is referred to set up a private network across a public network and usually can be classified by three types: [1] Remote–Access Type, which can
establish a connection between a client outside and a company's internal resources, Extranet Type, which connects different resources in different
networks, and Intranet Type, which creates a connection between different resources within one network. The working theory of VPN can be briefly
explained by a simple example including several steps:
Node A in Network I want to communicate to Node B in Network II via public network.
1. Since A wants to communicate with B, A will generate and send a packet whose destination IP is B's IP address in Network II.
2. The gateway of Network I gets A's packet and checks its destination IP, if belongs to

Sean Lee 11/20/2017 COMP 424 Term Paper TLS Fingerprinting and Client Identification The Transport Layer Security (TLS) is a security technique
that provides a method of selecting communication and encryption protocols that both a client and a server can effectively utilize. TLS provides
security for a wide variety of communication between networks, ranging from financial transactions on major retail websites, to private
communications between individuals, all the way down to malware returning the data it has illicitly acquired to the creator. TLS is effective because of
the inherent extreme difficulty any eavesdropper would experience, given that they were wishing to analyze the encrypted traffic and not simply record

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 degree of
accuracy,
