A Survey on Spam Filtering Methods and Mapreduce with SVMIRJET Journal
This document summarizes a research paper that surveys different spam filtering techniques, including machine learning approaches like Naive Bayes, KNN, decision trees, and SVM. It discusses how SVM is commonly used for spam filtering due to its ability to handle large datasets, but it has drawbacks of being slow for training on large data. The paper proposes using MapReduce with SVM to address this issue by enabling parallel processing of large input datasets to speed up SVM training for spam filtering. It provides background on various machine learning techniques used for spam filtering and discusses how MapReduce can help improve the scalability of SVM for classification of large volumes of email data as spam or not spam.
A Simple Segmentation Approach for Unconstrained Cursive Handwritten Words in...CSCJournals
This paper presents a new, simple and fast approach for character segmentation of unconstrained handwritten words. The developed segmentation algorithm over-segments in some cases due to the inherent nature of the cursive words. However the over segmentation is minimum. To increase the efficiency of the algorithm an Artificial Neural Network is trained with significant amount of valid segmentation points for cursive words manually. Trained neural network extracts incorrect segmented points efficiently with high speed. For fair comparison benchmark database IAM is used. The experimental results are encouraging.

Discussion Shared Practice The Triple Bottom LineIs the o.docxelinoraudley582231
Discussion: Shared Practice: The Triple Bottom Line
“Is the organization making a profit?” That is what most stakeholders think about when they look at the bottom line. Yet, an organization might be making a profit while dumping toxic waste into the environment, treating employees poorly, or failing to conserve resources. Nonfinancial performance measures such as these can be challenging to measure. The Triple Bottom Line (TBL) is a framework that incorporates nonfinancial factors in measuring the performance of an organization. In addition to assessing profitability, the TBL approach also assesses an organization’s social and ecological impact.
Today’s socially conscious executive thoroughly grasps the significance of the TBL in terms of organizational and cultural success. TBL, which is sometimes referred to as part of the broader term corporate social responsibility (CSR), is a measure of an organization’s financial health, environmental sustainability, and its furtherance of social justice. One question that can be used to assess if an organization is meeting TBL objectives is whether or not the human experience of all stakeholders is elevated due to its work.
To prepare for this Discussion, “Shared Practice: The Triple Bottom Line,” review the Learning Resources for this week and consider how the Triple Bottom Line is related to and affected by an organization’s performance. Reflect on the meaning of corporate social responsibility and how this might impact your role in promoting social change.
Post by Day 3, the following:
•Predict how the implementation of the Triple Bottom Line would affect your current or former organization’s performance. Be sure to include at least two short term consequences and at least two long term consequences of using the TBL measurement system.
•Provide an explanation of how you view the relationship between corporate profits and social responsibility.
•Describe how you (as an executive) plan to use some of the skills learned in this course to promote social change in your organization now and in the future.

Discussion Shared Practice The Triple Bottom LineIs the o.docxelinoraudley582231
Discussion: Shared Practice: The Triple Bottom Line
“Is the organization making a profit?” That is what most stakeholders think about when they look at the bottom line. Yet, an organization might be making a profit while dumping toxic waste into the environment, treating employees poorly, or failing to conserve resources. Nonfinancial performance measures such as these can be challenging to measure. The Triple Bottom Line (TBL) is a framework that incorporates nonfinancial factors in measuring the performance of an organization. In addition to assessing profitability, the TBL approach also assesses an organization’s social and ecological impact.
Today’s socially conscious executive thoroughly grasps the significance of the TBL in terms of organizational and cultural success. TBL, which is sometimes referred to as part of the broader term corporate social responsibility (CSR), is a measure of an organization’s financial health, environmental sustainability, and its furtherance of social justice. One question that can be used to assess if an organization is meeting TBL objectives is whether or not the human experience of all stakeholders is elevated due to its work.
To prepare for this Discussion, “Shared Practice: The Triple Bottom Line,” review the Learning Resources for this week and consider how the Triple Bottom Line is related to and affected by an organization’s performance. Reflect on the meaning of corporate social responsibility and how this might impact your role in promoting social change.
Post by Day 3, the following:
•Predict how the implementation of the Triple Bottom Line would affect your current or former organization’s performance. Be sure to include at least two short term consequences and at least two long term consequences of using the TBL measurement system.
•Provide an explanation of how you view the relationship between corporate profits and social responsibility.
•Describe how you (as an executive) plan to use some of the skills learned in this course to promote social change in your organization now and in the future.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

range 138.77.179.0/24.
A small network, referred to as shared, with interface ifint of the gateway router
connected to three other routers, referred to as staff_router, student_router, and
research_router. This network has no hosts attached (only four routers) and uses
network address 10.3.0.0/16.
A staff subnet, which is for use by staff members only, that is attached to the
staff_router router and uses network address 10.3.1.0/24.
A student subnet, which is for use by students only, that is attached to the
student_router router and uses network address 10.3.2.0/24.
A research subnet, which is for use by research staff, that is attached to the
research_router router and uses network address 10.3.3.0/24.
In summary, there are four routers in the network: the gateway router, and routers for each of
the staff, student and research subnets. There are five subnets: DMZ, shared, staff, student,
and research.
There are two servers in the DMZ that all can accept requests from the Internet: a web server
supporting HTTP and HTTPS, and a SMTP email server. Members of the staff, student and
research subnets can access the web server; members of the staff subnet only can access the
email server but using IMAP.
The gateway router also runs a stateful packet filtering firewall and performs port address
translation. In addition to the DMZ setup as described above, security requirements for the
educational institute are:
External Internet users cannot access any internal computers (except in DMZ and as
stated in other requirements).
Staff, students and researchers can access websites in the Internet.
The researchers (on the research subnet) run a server for sharing data with selected
research partners external to the educational institute. That server provides SSH
access and a specialised file transfer protocol using TCP and port 1234 to the partners.
The server has internal address 10.3.3.31 and NAT is setup on the gateway router to
map the public address 138.77.179.44 to the internal address. Currently there are two
partner organisations that can access the server, and they have network addresses:
31.13.75.0/24 and 23.63.9.0/24.
The professor that leads the research staff also wants access to the data sharing server
while they are at home. At home that professor uses a commercial ISP that
dynamically allocates IP addresses in the range 104.55.0.0/16.

Considering the above information, answer the following questions:
(a) Draw a diagram illustrating the network. Although there may be many computers in the
staff, student and research subnets, for simplicity you only have to draw three computers
in the staff subnet, three computers in the student subnet and three computers in the
research subnet (one of those in the research subnet should be the data sharing server).
Label all computers and router interfaces with IP addresses. [3 marks]
(b) Specify the firewall rules using the format as in the table below. You may add/remove
rows as needed. After the table, add an explanation of the rules (why you design the
firewall rules the way you did). [5 marks]

(c) Consider the rule(s) that allows the professor to access from home. Discuss the
limitations, and suggest possible solutions. [1 mark]
Marking Scheme
(a) 3 marks if correct network is drawn and labelled. 2 marks if some mistakes in location
of nodes or links, or allocation of addresses. 0 or 1 mark if multiple mistakes.
(b) If all necessary rules are included, and no unnecessary rules are included, you will
receive 5 marks. 0.5 mark will be deducted for an incorrect rule or incorrect
explanation of the rule. 0.5 mark will be deducted for a missing rule. 0.5 mark will be
deducted for a rule that is included but not needed. The explanation will only be
considered if the rules appear wrong or inappropriate.
(c) 1 mark if a relevant limitation is described, and a potential solution is relevant. 0.5

Question 3. Password Schemes [14 marks]
Objective: Understand what makes a strong password, and the difficulties of using
passwords for most users
You are the IT security administrator for an organisation with about 100 users. The users all
have office computers (PCs or laptops), but also use other computers for work (such as
shared computers, and personal mobile devices). For example, a typical user may use a
Windows PC in their office, occasionally use a Windows PC or Mac in a shared space or lab,
and regularly use their own Android or iOS phone for work purposes. There is a mix of
operating systems on computers and mobile devices.
You are tasked with educating users on passwords, and recommending password management
solutions to the organisation. You are considering two options for password management.
Option 1. Educate users to manage their own passwords, while using some technical
controls. This option involves recommending policies to management, providing user
training, and applying password management rules in various systems (e.g. when passwords
are created). Most users will not use password management software in this option.
Option 2. Enforce password management software for all users. This option requires all users
to use a single password management application (e.g. LastPass, KeePass, or `wallet’
software).
First considering Option 1, answer the following sub-questions.
(a) You are planning the user training session. You have already explained to users about
password lengths and character sets (e.g. minimum recommended length, types of
characters to include). List three (3) other recommendations that you think are the most
important for users to be aware of with regards to password usage and management. For
each recommendation, explain it in detail (that is, what would you tell users), and give
one advantage and one disadvantage of the recommendation. For example:
“Recommendation 1. You should do … . The advantage of doing this is … . But the
disadvantage of doing this is … .”. (Note you cannot use the password length and
character set as a recommendation – you must choose other recommendations) [3
marks]
(b) You are designing the technical controls on the password checking system when users
register or select a new password. One rule that you have decided to implement is that
a password must be at least 8 characters. List three (3) other rules that you think are
the most important to be implemented. For each rule, clearly specify the exact
conditions, and give one advantage and one disadvantage of the rule. For example:
“Rule 1. A password must be at least 8 characters long. The advantage of this rule is
… . The disadvantage of this rule is … .”. (Note you cannot use the password length as
a rule – you must choose 3 other rules. Also, although you may consider character set
as a rule, it can only count as one rule). [3 marks]
Now considering Option 2, answer the following sub-questions.
(c) Write a short summary of what password management software is, and how it works.
This summary is intended for management and users to understand. [2 marks]

7. COIT20262 Assignment 2 Term 1, 2017
(d) Explain the advantages and disadvantages of a password management application
(when compared to not using a password management application). [2 marks]
(e) Compare a web-based password management solution, such as LastPass, against a
standalone password management application, such as KeePass. In your comparison
explain the difference between the approaches and the advantages and disadvantages
of web-based versus standalone. [2 marks]
(f) If a standalone password management application is to be used, recommend where the
password database(s) for each user should be stored. Explain why you recommend
this approach. [2 marks]
Marking Scheme
(a) 1 mark for each correct and relevant recommendation that contains a description,
advantage and disadvantage.
(b) 1 mark for each correct and relevant rule that contains a description, advantage and
disadvantage.
(c) 2 marks for a clear and concise summary that mentions what it is and how it works. 1
mark if missing some important information.
(d) 2 marks if both the advantages and disadvantages are relevant and clearly explained.
(e) 2 marks if both the differences, and advantages and disadvantages are relevant and
clearly explained.
(f) 2 marks if the option for storage location is relevant, and the reasons for the location
are well justified.

Question 4. HTTPS and Certificates [10 marks]
Objective: Learn the steps of deploying a secure web server, as well as the
limitations/challenges of digital certificates
For this question you must use virtnet (as used in the workshops) to study HTTPS and
certificates. This assumes you have already setup and are familiar with virtnet. See Moodle
and workshop instructions for information on setting up and using virtnet, deploying the
website, and testing the website.
Your task is to:
Create topology 5 in virtnet
Deploy the MyUni demo website on the nodes
Setup the webserver to support HTTPS, including obtaining a certificate
certificate.pem.
Capture traffic from the web browser on node1 to the web server that includes a
HTTPS session. Save the file as https.pcap.
Test and analyse the HTTPS connection.
Answer the following sub-questions based on above test and analysis.
(a) Submit your certificate certificate.pem and HTTPS traffic capture https.pcap on
Moodle. [3 marks]
(b) Draw a message sequence diagram that illustrates the SSL packets belonging to the
first TCP connection in the file. Refer to the instructions in assignment 1 for drawing
a message sequence diagram, as well as these additional requirements:
Only draw the SSL packets; do not draw the 3-way handshake, TCP ACKs or
connection close. Hint: identify which packets belong to the first TCP
connection and then filter with “ssl” in Wireshark. Depending on your
Wireshark version, the protocol may show as “TLSv1.2”.
A single TCP packet may contain one or more SSL messages (in Wireshark look
inside the packet for each “Record Layer” entry to find the SSL message names).
Make sure you draw each SSL message. If a TCP packet contains multiple SSL
messages, then draw multiple arrows, one for each SSL message,
and clearly label each with SSL message name.
Clearly mark which packets/messages are encrypted. [3 marks]
(c) Based on the capture and your understanding of HTTPS: [0.5 mark each]
a. What port number does the web server use with HTTPS?
b. What symmetric key cipher was used for encrypting the data?
c. What public key cipher was used for exchanging a secret?
d. What cipher and what hash algorithm are used in signing the web servers
certificate?
(d) In this task you needed to manually load the CA certificate into the client (lynx web
browser). In real networks, this step is not necessary (that is, the web browser user does
not have to load the CA certificate – it normally is already loaded). Explain how the
Advanced Network Security Page 7 of 10
9. COIT20262 Assignment 2 Term 1, 2017
web browser already knows the CA certificate and what limitations there are of this
approach? [2 marks]
Marking Scheme
(a) 3 marks if all required files are submitted and in correct format. 1.5 marks if only 1
file is correct. 0 marks if neither of the files correct.
(b) The diagram must have all packets clearly labelled to obtain full marks. Missed
messages, incorrect messages or unclear diagram will result in loss of marks.
(c) 0.5 mark for each correct answer.
(d) 1 mark for explaining how the web browser knows certificate, and 1 mark for
explaining a limitation of this approach.

Question 5. Internet Privacy [11 marks]
Objective: Understand the advantages and disadvantages of Internet privacy technologies,
including VPNs, and learn about advanced techniques (Tor)
Encryption is commonly used to provide data confidentiality in the Internet: when two hosts
communicate, other entities in the path between the two hosts cannot read the data being sent.
However encryption on its own does not privacy of who is communicating. Although the
other entities cannot read the data, they can determine which two hosts are communicating.
Consider a simple view of an Internet path where client C is communicating using IPv4 with
server S. There are n routers on the path. Assume a malicious user, who wants to know
information about who is communicating and when, has access to one of the routers in the
path (router Rm), e.g. they can capture packets on that router. Note Rm is not directly
attached to the subnets of C or S.
(a) What information can the malicious user learn about who C and S are? Consider both
computer addresses and information that may identify the human user (e.g. names,
locations), and explain how the malicious user may obtain that information. [2 marks]
(b) If Network Address Translation (NAT) is used in the subnet for C (but not for S), how
does that change your answer to sub-question (a)? [1 mark]
One method for providing privacy in the Internet is using a Virtual Private Network (VPN).
Assume client C is using a VPN server which is located on a router in the path between C and
S (but not on Rm).
(c) What information can the malicious user learn about who is communicating when C
and S communicate via the VPN server? [1 mark]
(d) Potential disadvantages of using a VPN server include: reduced performance between
C and S; required to trust the VPN server; and VPN server logs may be
requested/accessed (by the malicious user). Explain each of these three potential
disadvantages. [3 marks]

11. COIT20262 Assignment 2 Term 1, 2017
Onion routing, used in Tor, is another method for providing privacy in the Internet. It is
generally consider to provide more privacy than using a VPN. The following sub-questions
require you to learn the basics of Tor.
(e) Explain how Tor (or onion routing) works. Use the scenario of C and S as an example.
That is, how would C communicate with S if Tor was used instead of a VPN. [2 marks]
(f) What are the advantages of Tor compared to VPN? [1 mark]
(g) What are the disadvantages of Tor computer to VPN? [1 mark]
Marking Scheme
(a) All relevant information listed and explained to receive 2 marks. Missing information
or poor explanations: 0 or 1 mark.
(b) 1 mark for clear explanation.
(c) 1 mark for clear explanation.
(d) 1 mark for each disadvantage clearly explained.
(e) 2 marks for clear explanation. Missing information or poor explanations: 0 or 1 mark.
