How to 2FA-enable Open Source Applications
How to 2FA-enable Open Source Applications (Extended Session)
Presented at: Open Source 101 at Home 2020
Presented by: Mike Schwartz, Gluu
Abstract: Your organization loves open source tools like Wordpress, SuiteCRM, NextCloud, RocketChat, and OnlyOffice... but most of these tools are protected with plain old passwords. You want to use two-factor authentication... but how? In this workshop, you'll learn:
- Which 2FA technologies can be used without paying a license;
- How to enable users to enroll and delete 2FA credentials;
- How to configure open source applications to act as a federated relying party--delegating authentication to a central service
- How custom applications can act as a federated relying party
CONFidence2015: Real World Threat Hunting - Martin Nystrom
Real World Threat Hunting
Security threats have grown from network annoyances to attacks on sensitive infrastructure; penetrating network perimeters, moving laterally within networks, breaching new device types, and cloaking movements. This presentation will share techniques utilized by Cisco to detect and investigate sophisticated, embedded threats.
The speaker, who has conducted monitoring and investigations on customer networks, will review recent real attacks observed on customer networks, from discovery to remediation, and provide lessons learned. These interactive case examples will highlight how to identify these threats using security intelligence, expert staff, and the Cisco OpenSOC platform.
Examples of attacks and illustrations:
* Sophisticated phishing attacks targeted at customer environments.
* Breaches and data exfiltration resulting from the high-profile HeartBleed and Shellshock vulnerabilities.
* Sophisticated malware targeting financial institutions with the goal of data theft.
* Use of full packet capture to identify data exfiltration.

Targeted Threat (APT) Defense for Applications Featuring pxGrid: a deep dive
A session in the DevNet Zone at Cisco Live, Berlin. Targeted Attacks, which the media refers to as APTs, are threats that must be addressed by any organization requiring networked computers to do business. In this session we will go over the run book techniques used by these threat actors and then go over strategies for mitigating those attacks. In this session we will focus on the concepts that developers of network applications need to be aware of to mitigate these styles of attacks and techniques to use. To finish off, we will delve into pxGrid and what it can offer to break these APT style attack playbooks. Backgrounder: We obtained knowledge of these run book techniques from trusted advisors, peers in the industry and from our own observations. Our own observations included information from our CSIRT, our security products in the field as well as our internal phishing awareness campaign. After studying these techniques we devised strategies to mitigate them. Those strategies were then tested and deployed throughout our ecosystem. The Cisco CSDL initiative and ACT2 chips will also be techniques and tools highlighted in this session.

CSIA 413: Cybersecurity Policy, Plans, and Programs
June 2, 2019
Executive Summary
The Red Clay Renovations Employee Handbook is to give general rules about its strategies. The Employee Handbook will fill in as a guide for workers to get comfortable with Red Clay Renovations strategies for "Acceptable Use Policy for Information Technology", "Bring Your Own Device Policy " and "Digital Media Sanitization, Reuse, and Destruction Policy". Red Clay Renovations maintains whatever authority is needed to adjust the Employee Handbook to best suit the organization whenever with no earlier warning to its representatives.
Red Clay Renovations "Acceptable Use Policy for Information Technology" will characterize in subtleties what Acceptable Use is and what it's most certainly not. Every Employee will get his/her duty of the framework accounts, processing resources, organize utilization and will sign and consent to the approach before access is conceded to the system.
Red Clay Renovations "Bring Your Own Device Policy or BYOD" will name every one of the gadgets that are satisfactory as BYOD and the administration of the use of such gadgets. Every worker's gadgets must satisfy the arrangement guideline before actualizing the gadgets into Red Clay Renovation Company.
Red Clay Renovations "Digital Media Sanitization, Reuse, and Destruction Policy" will ensure that any worker of Red Clay Renovation who marked for the BYOD approach has/should sign this arrangement also. Workers need to comprehend the techniques the organization will use to clean off the BYOD.
Acceptable Use Policy
Introduction
This Acceptable Use Policy is for all Red Clay Renovation workers and supplants every single past version. All workers are liable to the terms and states of the Policy. The approach will build up satisfactory and inadmissible utilization of defending the security of information, secure and ensure PC and PCs, the use of system condition and servers, the utilization of electronic correspondences. Additionally Red Clay Renovation gathers, keeps up, and stores individual data to incorporate Mastercard’s, credit checks, building plans and illustrations, customers restorative and wellbeing information.
Red Clay Renovation must be in consistence with the accompanying: HIPPA Privacy and Security Rule, Freedom of Information Act (FOIA), PCI DSS, Privacy Act of 1977, Building Codes and Regulations. It is to the greatest advantage of the organization for all workers to comprehend the Acceptable Use Policy to settle on trustworthy choices before participating in inadmissible utilization of the approach. Any offense with the Acceptable Use Policy could conceivably cause Red Clay Renovation considerable loss of its business and its notorieties. On the off chance that any worker needs more data with this arrangement, they can reach out to the IT department directly.

CSIS 100CSIS 100 - Discussion Board Topic #1One of the object.docx
CSIS 100
CSIS 100 - Discussion Board Topic #1:
One of the objectives of this course is to enable students to differentiate between the disciplines of Information Systems, Information Technology, and Computer Science. Oftentimes, these areas overlap and are difficult to distinguish – even among professionals within the industries.
There are some distinctions that become evident, but all too frequently, people do not understand these distinctions until they are already deep within their programs of study. Consequently, many decide that it is too late to pursue a different avenue in the computing world without losing valuable time and money spent on courses that may or may not apply to a different major.
Given the importance of achieving effective planning from the beginning, your first assignment in this course is to delve into the broad areas of Information Systems, Information Technology, and Computer Science and write about your career choice in a discussion board post. This should be your thought process:
· First, define each field (i.e. IS, IT, CS). Understand the similarities and differences.
· Second, determine what jobs are available in each area.
· Third, look at the degree completion plans for each of these programs.
· Fourth, assess your own skills (e.g. Are you good in math? Do you like business? Do you like algorithms? Are you gifted at problem-solving? Do you like learning about new technology? Do you enjoy working hands-on with equipment/hardware/wires?)
· Fifth, (and most importantly) ask God what He wants you to pursue based on your talents, interests, and abilities.
· Sixth, based on your analysis above, what career do you hope to obtain after graduation, and what degree will you pursue to achieve this goal?
To facilitate your research, there are four videos in your Reading & Study folder that will help you understand the differences between the computing fields and become familiar with the job opportunities in each area. Be sure to view these videos first.
The LU Registrar’s home page has information on degree completion plans. Here is a link to all of the currently available ones in the university:
http://www.liberty.edu/academics/registrar/index.cfm?PID=2981
Be sure to look at all of the ones listed for Information Systems and Information Technology. At the time of this writing, Computer Science is only listed under residential degree plans. That does not mean that you should rule out Computer Science as a potential major. You must consider all options and listen to God’s calling upon your life. With God, all things are possible.
Discussion Board Deliverables
Main Post:
In a minimum of 300 words, create a thread in Module 1’s discussion board forum that describes the following:
1. Your desired career upon graduation
2. Why you chose this career
3. Your intended major
4. Your strengths, weaknesses, and interests
5. How the major supports your chosen career
6. How God has led you to reach your decision
7. A Bib.

CSIA 413: Cybersecurity Policy, Plans, and Programs
June 2, 2019
Executive Summary
The Red Clay Renovations Employee Handbook is to give general rules about its strategies. The Employee Handbook will fill in as a guide for workers to get comfortable with Red Clay Renovations strategies for "Acceptable Use Policy for Information Technology", "Bring Your Own Device Policy " and "Digital Media Sanitization, Reuse, and Destruction Policy". Red Clay Renovations maintains whatever authority is needed to adjust the Employee Handbook to best suit the organization whenever with no earlier warning to its representatives.
Red Clay Renovations "Acceptable Use Policy for Information Technology" will characterize in subtleties what Acceptable Use is and what it's most certainly not. Every Employee will get his/her duty of the framework accounts, processing resources, organize utilization and will sign and consent to the approach before access is conceded to the system.
Red Clay Renovations "Bring Your Own Device Policy or BYOD" will name every one of the gadgets that are satisfactory as BYOD and the administration of the use of such gadgets. Every worker's gadgets must satisfy the arrangement guideline before actualizing the gadgets into Red Clay Renovation Company.
Red Clay Renovations "Digital Media Sanitization, Reuse, and Destruction Policy" will ensure that any worker of Red Clay Renovation who marked for the BYOD approach has/should sign this arrangement also. Workers need to comprehend the techniques the organization will use to clean off the BYOD.
Acceptable Use Policy
Introduction
This Acceptable Use Policy is for all Red Clay Renovation workers and supplants every single past version. All workers are liable to the terms and states of the Policy. The approach will build up satisfactory and inadmissible utilization of defending the security of information, secure and ensure PC and PCs, the use of system condition and servers, the utilization of electronic correspondences. Additionally Red Clay Renovation gathers, keeps up, and stores individual data to incorporate Mastercard’s, credit checks, building plans and illustrations, customers restorative and wellbeing information.
Red Clay Renovation must be in consistence with the accompanying: HIPPA Privacy and Security Rule, Freedom of Information Act (FOIA), PCI DSS, Privacy Act of 1977, Building Codes and Regulations. It is to the greatest advantage of the organization for all workers to comprehend the Acceptable Use Policy to settle on trustworthy choices before participating in inadmissible utilization of the approach. Any offense with the Acceptable Use Policy could conceivably cause Red Clay Renovation considerable loss of its business and its notorieties. On the off chance that any worker needs more data with this arrangement, they can reach out to the IT department directly.

CSIS 100
CSIS 100 - Discussion Board Topic #1:
One of the objectives of this course is to enable students to differentiate between the disciplines of Information Systems, Information Technology, and Computer Science. Oftentimes, these areas overlap and are difficult to distinguish – even among professionals within the industries.
There are some distinctions that become evident, but all too frequently, people do not understand these distinctions until they are already deep within their programs of study. Consequently, many decide that it is too late to pursue a different avenue in the computing world without losing valuable time and money spent on courses that may or may not apply to a different major.
Given the importance of achieving effective planning from the beginning, your first assignment in this course is to delve into the broad areas of Information Systems, Information Technology, and Computer Science and write about your career choice in a discussion board post. This should be your thought process:
· First, define each field (i.e. IS, IT, CS). Understand the similarities and differences.
· Second, determine what jobs are available in each area.
· Third, look at the degree completion plans for each of these programs.
· Fourth, assess your own skills (e.g. Are you good in math? Do you like business? Do you like algorithms? Are you gifted at problem-solving? Do you like learning about new technology? Do you enjoy working hands-on with equipment/hardware/wires?)
· Fifth, (and most importantly) ask God what He wants you to pursue based on your talents, interests, and abilities.
· Sixth, based on your analysis above, what career do you hope to obtain after graduation, and what degree will you pursue to achieve this goal?
To facilitate your research, there are four videos in your Reading & Study folder that will help you understand the differences between the computing fields and become familiar with the job opportunities in each area. Be sure to view these videos first.
The LU Registrar’s home page has information on degree completion plans. Here is a link to all of the currently available ones in the university:
http://www.liberty.edu/academics/registrar/index.cfm?PID=2981
Be sure to look at all of the ones listed for Information Systems and Information Technology. At the time of this writing, Computer Science is only listed under residential degree plans. That does not mean that you should rule out Computer Science as a potential major. You must consider all options and listen to God’s calling upon your life. With God, all things are possible.
Discussion Board Deliverables
Main Post:
In a minimum of 300 words, create a thread in Module 1’s discussion board forum that describes the following:
1. Your desired career upon graduation
2. Why you chose this career
3. Your intended major
4. Your strengths, weaknesses, and interests
5. How the major supports your chosen career
6. How God has led you to reach your decision

CSIA 413: Cybersecurity Policy, Plans, and ProgramsProject #4: IT Audit Policy and Plans Company Background & Operating Environment
Red Clay Renovations is an internationally recognized, awarding winning firm that specializes in the renovation and rehabilitation of residential buildings and dwellings. The company specializes in updating homes using “smart home” and “Internet of Things” technologies while maintaining period correct architectural characteristics. Please refer to the company profile (file posted in Week 1 > Content > CSIA 413 Red Clay Renovations Company Profile.docx) for additional background information and information about the company’s operating environment.Policy Issue & Plan of Action
The corporate board was recently briefed by the Chief Information Officer concerning the company’s IT Security Program and how this program contributes to the company’s risk management strategy. During the briefing, the CIO presented assessment reports and audit findings from IT security audits. These audits focused upon the technical infrastructure and the effectiveness and efficiency of the company’s implementation of security controls. During the discussion period, members of the corporate board asked about audits of policy compliance and assessments as to the degree that employees were (a) aware of IT security policies and (b) complying with these policies. The Chief Information Officer was tasked with providing the following items to the board before its next quarterly meeting:
(a) Issue Specific Policy requiring an annual compliance audit for IT security policies as documented in the company’s Policy System
(b) Audit Plan for assessing employee awareness of and compliance with IT security policies
a. Are employees aware of the IT security policies in the Employee Handbook?
b. Do employees know their responsibilities under those policies?
(c) Audit Plan for assessing the IT security policy system
a. Do required policies exist?
b. Have they been updated within the past year?
c. Are the policies being reviewed and approved by the appropriate oversight authorities (managers, IT governance board, etc.)?
Your Task Assignment
As a staff member supporting the CISO, you have been asked to research this issue (auditing IT security policy compliance) and then prepare an “approval draft” for a compliance policy. You must also research and draft two separate audit plans (a) employee compliance and (b) policy system audit. The audit policy should not exceed two typed pages in length so you will need to be concise in your writing and only include the most important elements for the policy. Make sure that you include a requirement for an assessment report to be provided to company management and the corporate board of directors.
· For the employee compliance assessment, you must use an interview strategy which includes 10 or more multiple choice questions that can be used to construct a web-based survey of all employees. The questions should be split.

W. H. Auden
About suffering they were never wrong,
The old Masters: how well they understood
Its human position: how it takes place
While someone else is eating or opening a window or just walking
dully along;
How, when the aged are reverently, passionately waiting
For the miraculous birth, there always must be
Children who did not specially want it to happen, skating
On a pond at the edge of the wood:
They never forgot
That even the dreadful martyrdom must run its course
Anyhow in a corner, some untidy spot
Where the dogs go on with their doggy life and the torturer's horse
Scratches its innocent behind on a tree.
In Breughel's Icarus, for instance: how everything turns away
Quite leisurely from the disaster; the ploughman may
Have heard the splash, the forsaken cry,
But for him it was not an important failure; the sun shone
As it had to on the white legs disappearing into the green
Water, and the expensive delicate ship that must have seen
Something amazing, a boy falling out of the sky,
Had somewhere to get to and sailed calmly on.

Homework 2 – 50 points
Sockets (10 points)
1. For a client-server application over TCP, why must the server program be executed before the
client program?
2. For a client-server application over UDP, why may the client program be executed before the
server program?
3. The UDP server shown in the course slides needed only one socket, whereas the TCP server
needed two sockets. Why?
4. If the TCP server were to support N simultaneous connections, each from a different client host,
how may sockets would the TCP server need?
5. You are creating an event logging service that will be handling event messages from multiple
remote clients. This service can suffer delays in message delivery and even the loss of some
event messages. Would you implement this using TCP or UDP? Why?
The HTTP GET message (10 Points)
Consider the figure below, where a client is sending an HTTP GET message to a web server,
gaia.cs.umass.edu.

Assignment 41
This set of exercises will strengthen your ability to write relatively simple shell scripts
using various filters. As always, your goals should be clarity, efficiency, and simplicity. It
has two parts.
1. The background context that was provided in the previous assignment is repeated here
for your convenience. A DNA string is a sequence of the letters a, c, g, and t in any
order, whose length is a multiple of three2. For example, aacgtttgtaaccagaactgt
is a DNA string of length 21. Each sequence of three consecutive letters is called a codon.
For example, in the preceding string, the codons are aac, gtt, tgt, aac, cag, aac,
and tgt.
Your task is to write a script named codonhistogram that expects a file name on the
command line. This file is supposed to be a dna textfile, which means that it contains
only a DNA string with no newline characters or white space characters of any kind; it is
a sequence of the letters a, c, g, and t of length 3n for some n. The script must count the
number of occurrences of every codon in the file, assuming the first codon starts at
position 13, and it must output the number of times each codon occurs in the file, sorted
in order of decreasing frequency. For example, if dnafile is a file containing the dna
string aacgtttgtaaccagaactgt, then the command
codonhistogram dnafile
should produce the following output:
3 aac
2 tgt
1 cag
1 gtt
because there are 3 aac codons, 2 tgt, 1 cag, and 1 gtt. Notice that frequency comes
first, then the codon name.

Lecture 4B: Work Breakdown Structure
Gursimran Singh Walia
North Dakota State University
[email protected]
*
The Work Breakdown StructureA work breakdown structure (WBS) is an outcome-oriented analysis of the work involved in a project that defines the total scope of the projectIt is a foundation document in project management because it provides the basis for planning and managing project schedules, costs, and changes
Approaches to Developing WBSsUsing guidelines: Some organizations, like the DOD, provide guidelines for preparing WBSsThe analogy approach: It often helps to review WBSs of similar projectsThe top-down approach: Start with the largest items of the project and keep breaking them downThe bottoms-up approach: Start with the detailed tasks and roll them up
Basic Principles for Creating WBSs*
1. A unit of work should appear at only one place in the WBS.
3. A WBS item is the responsibility of only one individual, even though many people may be working on it.
4. The WBS must be consistent with the way in which work is actually going to be performed; it should serve the project team first and other purposes only if practical.
5. Project team members should be involved in developing the WBS to ensure consistency and buy-in.
6. Each WBS item must be documented to ensure accurate understanding of the scope of work included and not included in that item.
7. The WBS must be a flexible tool to accommodate inevitable changes while properly maintaining control of the work content in the project according to the scope statement. *Cleland, David I. Project Management: Strategic Design and Implementation, 1994
Good WBS Design PrinciplesThe 100% RuleThe WBS defines 100% of the work of the projectAnything that isn’t defined in the WBS is outside the scope of the project.The work content on any item is the sum of what is included under that work itemUpper Levels are Planned outcomes (deliverables), not planned actionsEnds of WBS include the activities needed to create the project deliverablesMutually-exclusive elementsWork should only appear in one place in the WBSWBS must be consistent with the way the project will be performed and controlledMust be easy to update
WBS RolePartition the major project deliverables into smaller components to improve the accuracy of cost estimatesProvide a mechanism for collecting actual costsProvide a mechanism for performance measurement and control
Why create a WBS?Cost EstimatingCost BudgetingResource PlanningRisk Management PlanningActivity Definition

CSCI 561Research Paper Topic Proposal and Outline Instructions.docx
CSCI 561
Research Paper: Topic Proposal and Outline Instructions
The easiest approach for selecting a topic for your paper might be to review the various subject areas covered in the course readings (i.e., search the bibliographies of the textbooks). Although the chosen topic must relate directly to the general subject area of this course, you are not limited to the concepts, techniques, and technologies specifically covered in this course.
Each Topic Outline must include the following 3 items:
1. A brief (at least 3–4 bullets with 1–2 sentences per bullet) overview of the research topics of your paper – you will need to address these in the actual paper. This will be titled “Research Objectives”.
2. A list of at least 3 questions (in a numbered list) you intend your research to ask and hopefully answer. These must be questions that will require you to draw conclusions from your research. These must not be questions to answer your research objectives. This section will be titled “Questions”
3. At least 3 initial research sources, 1 of which is an academic journal or other peer reviewed source. These should match APA formatting of sources.
Example formats for Topic Outlines (an example, not a template):
Research Objectives
· Briefly describe the overall concept of system integration.
· Discuss the traditional approach of big-bang integration including the major advantages and disadvantages of this approach.
· Discuss the traditional approaches of top-down and bottom-up integration and their major advantages and disadvantages.
· Discuss the traditional approach of mixed integration, combining the desirable advantages from the top-down and bottom-up integration approaches.
Questions
1. Why is system integration an important step in the software development process?
2. Why has big-bang integration not survived as a useful testing method?
3. Why have top-down and bottom-up integration not been replaced by more modern methods?
4. Why would you use mixed integration all the time rather than sometimes using top-down and bottom-up integration exclusively?

You are going to write a Python program that represents a command line version of a hexadecimal editor.
This program will be similar to the Linux built-in command line hexadecimal editors such as xxd and
hexdump.
The program will first ask the user to enter the name of any file you want to read. Your program will then
print the binary contents of the file into the standard output (screen). The output will be divided into three
main sections: the offset values in decimal, sixteen space-separated hexadecimal bytes, followed by the
same sixteen bytes but in ASCII value. The figure below shows an example of the first 48 bytes of an
output, and the three different sections:
Notice that in the 2nd section there a space between the 8th and 9th byte. Each output line represents 16 bytes.
The first column shows the decimal offset, where the first byte from the first line represents the 0th byte;
the second line starts with byte 16th and so on. The final section only shows the printable ASCII characters.
These are the ASCII characters can be printed on the screen (usually they are the characters with ASCII
values between 0x20 and 0x7EThe rest of the unprintable bytes are replaced by a period ('.'). The following
built-in Python functions will be useful in this situation: chr, hex, ord. More information about these
functions can be found here: https://docs.python.org/3/library/functions.html

CSCE509–Spring2019Assignment3updated01May19DU.docx
CSCE 509 – Spring 2019
Assignment 3 // updated 01May19
DUE: May 11, 2019 at 5 p.m.
• Two data sets available on Moodle
o {concaveData.npy, concaveTarget.npy}
o {testData.npy, testTarget.npy}
• Write TensorFlow code to perform DNN classification with three (3) classes
• Use concave*.npy for training
• Use test*.npy for test
• Data is the data matrix; Target is the labeled targets from {0, 1, 2}
• Do each of the following steps. For each step: Note the accuracy of the classification using
the test data set. Discuss the results.
1. Write TensorFlow code to perform DNN classification using default settings. Define your
own architecture with two hidden layers. Calculate the number of parameters in your
network. Do not let the number of parameters exceed the number of input samples in
concave*.npy
2. Use one or two additional layers compared to (1) but be sure that the number of
parameters do not exceed the number of input samples. Which has better accuracy
performance? Or are they about the same?
3. Write Python code to read in the data sets. Add a large constant (such as “509” or “5090”)
to each input feature. Write the data sets as files, to be read in as input sets. Repeat the
classification using the new input files with the architecture that has better performance
in (1) or (2). What is the accuracy performance for the same number of epochs? If the
accuracy performance is about the same, does it converge faster or slower or about the
same?
4. Use the given data sets as used in (1) and (2). Use either of the two architectures. Change
the tf.layers.dense() function initlialization to He initialization by using the
variance_scaling_initializer() function:
he_init = tf.contrib.layers.variance_scaling_initializer(factor=2.0)
hidden1 = tf.layers.dense(X, n_hidden1, activation=tf.nn.relu,
kernel_initializer=he_init, name=”hidden1”)
# do the same for other hidden layers
What is the accuracy performance? Compare to either (1) or (2).
5. Take the architecture from either (1) or (2). Replace the relu activation function by the
exponential linear unit (ELU). In the tf.layers.dense function, use
activation=tf.nn.elu
What is the accuracy performance? Compare to either (1) or (2) and to (4).
6. Perform batch normalization on either (1) or (2) as follows. We want to zero-center and
normalize the inputs to the activation function of each layer by learning the mean and
scales of the inputs for each layer. Modify the Python code as follows:
X = tf.placeholder(tf.float32, shape=(None, n_inputs), name=”X”)
training = tf.placeholder_with_default(False, shape=(), name=”training”)
Then in defining the hidden layers:
hidden1 = tf.layers.dense(X, n_hidden1, name=”hidden1”)
batchnorm1 = tf.layers.batch_normalization(hidden1, training=training,
momentum=0.9)
bn1_act = tf.nn.elu(batchnorm1)
hidden2 = tf.layers.dense(bn1_act, n_hidden2, name=”hidden2”)
batchnorm2 = tf.layers.batch_normalization.

Output: the matrix resulting from swapping rows i and j, i.e. performing the
row operation Ri $ Rj .
function B = scaling(A, i, s)
Input: a rectangular matrix A, an integer i, and a scalar s.
Output: the matrix resulting from multiplying all entries in row i by s, i.e. per-
forming the row operation Ri sRi.
function B = replacement(A, i, j, s)
Input: a rectangular matrix A, two integers i and j, and a scalar s.
Output: the matrix resulting from adding s times row j to row i, i.e. performing

Project 3 – Hopscotch Hash Table
Due: 11:59 PM on Friday, June 21, 2019
PROGRAM DESCRIPTION
In this C++ program, you will implement an efficient hopscotch hash table that improves
on the classic linear probing algorithm. Specifically, you will use a TABLE_SIZE = 17
and use the single hash function ℎ(𝑥) = 𝑥 mod 𝑇𝐴𝐵𝐿𝐸_𝑆𝐼𝑍𝐸. You shall resolve
collisions using linear probing where the maximal length of the probe sequence (i.e.,
distance away from the original hash location) is bound by the hopscotch hash
algorithm where MAX_DIST = 4.
You shall support the following five operations that are menu driven:
1. Insert Value
2. Delete Value
3. Search Value
4. Output Table
5. Exit Program
All data shall be entered through the console and consist of integers. You may assume
valid data, though data may be out of range (i.e., zero, negative integers or possibly out
of range of menu options). Your algorithm to find the next available slot is bound by the
end of the table so that the linear probe sequence need not be circular. In other words,
you do not need to wrap around beyond the last element of the array to the first for
either the linear probe or the bound for the hopscotch algorithm. For example, if the
user attempts to insert 33 which hashes to index position 16 (i.e., 33 % TABLE_SIZE) in
the array, but an element already exists at that location, the insert will fail as there are
no more array locations beyond this to attempt to insert the element.
You must keep an item array containing the elements as well as an associated hop
array that indicates positions in the item array that are occupied with items that hash to
the same value. You should also provide specific feedback to the user on successful
operations or when an operation failed. The search should utilize the hash value and
then perhaps a linear probe of MAX_DIST – 1 index locations, but you should not
simply search the entire array to accomplish this operation. Be sure to handle the case
that requires multiple hops (i.e., using recursion) to get the value within the correct
range.
REQUIREMENTS
• Your code should be well documented in terms of comments. For example, good
comments in general consist of a header (with your name, course section, date,
and brief description), comments for each variable, and commented blocks of
code.
• Your program will be graded based largely on whether it works correctly on the
CSE machines (e.g., cse01, cse02, …, cse06), so you should make sure that
your program compiles and runs on a CSE machine.

Cryptography is the application of algorithms to ensure the confiden.docx
Cryptography is the application of algorithms to ensure the confidentiality, integrity, and availability of data, while it is at rest, in motion, or in use. Cryptography systems can include local encryptions at the file or disk level or databases. Cryptography systems can also extend to an enterprise-wide public key infrastructure for whole agencies or corporations.
The following are the deliverables for this project:
Deliverables
Enterprise Key Management Plan:
An eight- to 10-page double-spaced Word document with citations in APA format. The page count does not include figures, diagrams, tables, or citations.
Enterprise Key Management Policy:
A two- to three-page double-spaced Word document.
Lab Report:
A Word document sharing your lab experience along with screenshots.
There are seven steps to complete the project. Most steps of this project should take no more than two hours to complete. The entire project should take no more than one week to complete. Begin with the workplace scenario, and then continue to Step 1, “Identify Components of Key Management.”
When you submit your project, your work will be evaluated using the competencies listed below. You can use the list below to self-check your work before submission.
Step 1: Identify Components of Key Management
Key management will be an important aspect of the new electronic protected health information (e-PHI). Key management is often considered the most difficult part of designing a cryptosystem.
Choose a fictitious or an actual organization. The idea is to provide an overview of the current state of enterprise key management for Superior Health Care.
Review these authentication resources to learn about
authentication
and the characteristics of key management.
Provide a high-level, top-layer network view (diagram) of the systems in Superior Health Care. The diagram can be a bubble chart or Visio drawing of a simple network diagram with servers. Conduct independent research to identify a suitable network diagram.
Read these resources on
data at rest
, data in use, and
data in motion
.
Identify data at rest, data in use, and data in motion as it could apply to your organization. Start by focusing on where data are stored and how data are accessed.
Review these resources on insecure handling, and identify areas where
insecure handling
may be a concern for your organization.
Incorporate this information in your key management plan.
In the next step, you will consider key management capabilities.
Step 3: Identify Key Management Gaps, Risks,
Solution
s, and Challenges
In the previous step, you identified the key components of an enterprise key management system. In this step, you will conduct independent research on key management issues in existing organizations. You will use this research to help identify gaps in key management, in each of the key management areas within Superior Health Care.
Conduct independent research to identify typical gaps in key manage.
CSc3320 Assignment 6 Due on 24th April, 2013 Socket programming .docx
CSc3320 Assignment 6 Due on 24th April, 2013
Socket programming code (server.c & client.c) demoed in class implement a server-client communication by socket. The server sets up a socket and waits for communication request from a client. The client tries to connect to server and asks user for a message to send to server after the connection established. Server then accepts the communication, reads the message, displays it and send confirmation message to the client. The client reads confirmation from server and displays it too.
Please modify the server.c such that the server can carry out the same communication with
3
clients. It creates a child process (fork()) every time a communication request from one client arrives and continues to wait to serve the next client. This child process takes care of reading message/sending confirmation from/to the corresponding client and terminates with the exit code 0. After serving all 3 clients, the server needs to accept (wait()) termination of all child processes it created. Server prints out message about the child process ID and the exit code every time it accepts the termination of a child process (eg. “A child with PID 1959 terminated with exit code 0”).

Cryptography KeysCryptography provides confidentiality, inte.docx
Cryptography Keys
Cryptography provides confidentiality, integrity authentication, and nonrepudiation for sensitive information while it is stored (at rest), traveling across a network (in transit), and existing in memory (in use). Cryptography keys play in the world of data security and are an extremely important security technology embedded in many of the security controls used to protect information from unauthorized visibility and use.
Let’s say you work for one of the following types of industry:
Manufacturing
Government
Research
Service
Consulting
After you choose one of the above, consider the three types of algorithms commonly used today. Which do you find to be the most secure? Which is the most complex? Which did you struggle to understand? What do you think you need to know as a manager in order to choose the right security systems for your company? Be sure to fully develop your responses and support your opinion with reasons from your study this week.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
