This is a three part question. For each part the answer requires identifying an asymmetric encryption technique, hashing or both. As part of each question you need to discuss the technique to demonstrate your understanding of how the functionality (confidentiality, authenticity, integrity) is supported. You need to discuss the details of what the sender and receiver do and the key usage if applicable. What technique is used to exchange messages between two parties ensuring confidentiality? Discuss. What technique is used to exchange messages between two parties ensuring authenticity? Discuss c. What technique is used to exchange messages between two parties ensuring integrity? Discuss. Solution a. Ensuring confidentiality, a very key component of protecting information confidentiality would be Encryption. Encryption ensures that only the right person who knows the key can read the information. Encryption is very widespread in today’s world while interacting with one another through internet. It is the most effective way to achieve the data security. Secure Socket Layer and Transport Layer Security are the security protocols for communication over internet. Example: Internet Banking. Other ways to make sure that the data remains confidential is to implement file permissions and access control list to restrict access to sensitive information and design of file permissions and access control lists must be kept as easy as possible for proper maintenance. c. Integrity means protecting information so that it cannot be customized by not permitted people. Information is only as valuable as it is perfect. Similar to the data confidentiality, encryption plays a prominent role in preserving data integrity. The data shared with another person within a company or externally to a third party or creating an automatic system report containing sensitive information, these all data should be encrypted to prevent the data or sensitive information of a company to be accessed and changed by the third person. The data stored on file shares allow encryption can prevent the data from being altered by malicious objective or being accessed by individuals who do not have access. When accessing data integrity and designing security requirements it is necessary to ensure the level of encryption is sufficient to protect the integrity of the data, the more sensitive the data the higher the level of encryption that needs to be enabled..

There are innumerable ways that data thieves can attack and penetrate your network. As the saying goes - it’s not if your systems will be breached, but when. Every organization, especially those that handle PCI data, should operate under the assumption that sooner or later, they will be breached. The new best practices to protect sensitive data and the data flow throughout the enterprise are designed with this assumption in mind. They are about reducing risk of data loss, and responding quickly to attacks when they occur. First, minimize the amount of sensitive data you collect and store. Some elements, such as PIN numbers and CVV/CVC codes, are prohibited from being stored, but in general, if you’re not using certain data but you store it anyways, you’re only increasing risk with no returns. If you are using it, or planning to, minimize the number of systems that store or process sensitive data. This will make it easier to protect it, as you will have less to defend. The next step is to implement some sort of data security, as required by PCI DSS regulations. While access controls provide a basic level of protection, they do nothing to protect the data flow, and the PCI council has recognized a need to go beyond them. Data security is applied in one of two ways: coarse-grained security at the volume or file level; and fine-grained security at the column or field-level.

Cryptography in the past was used in keeping military information, diplomatic correspondence secure and in protecting the national security. However, the use was limited. Nowadays, the range of cryptography applications have been expanded a lot in the modern area after the development of communication means; cryptography is essentially required to ensure that data are protected against penetrations and to prevent espionage. Also, cryptography is a powerful mean in securing e-commerce. Cryptography is used to ensure that the contents of a message are confidentiality transmitted and would not be altered. Confidentiality means nobody can understand the received message except the one who has the decipher key, and data cannot be changed means the original information would not be changed or modified; this is done when the sender includes a cryptographic operation called a hash function in the original message. A hash function is a mathematical representation of the information, when any information arrives at its receiver; the receiver calculates the value of this hash function. If the receiver’s hash function value is equivalent to the sender’s, the integrity of the message is assured .

Running Head: DATA BREACH 1 DATA BREACH 9 Data Breach Research Proposal Introduction In the present world, there has been a series of technological advancements especially in this era of digital migration where everybody is using technology. However, a lot of people do not realize that there are problems that arise as technological changes continue happening. One of the biggest challenge faced in the technological environment is data breaching. This refers to incidences where an individual’s private and confidential information is accessed by unauthorized individuals. Due to diverse lack of technological knowhow, a lot of people and organizations have become victims as occurrences of these data breaches rise each day. In the last two years at least 258,000 organizations has fallen as an estimate of about 3.9 million individuals from different parts of the world has been robbed as a result of data breaches (Ayyagari, 2012). Clearly, the victim figure above emphasizes the need to come up with a solution to the data breaches more than ever before. The motivation behind carrying out the author’s my proposed research is the rapid changes in the world of technology thatwhich does not match the rate at which a big population adjusts along with the technological changes. This makes them vulnerable to more and more data breaches every day if something is not done. I believe that creating awareness concerning how to be data secure will greatly impact the world positively through reducing the data breaches occurrences. In my research, I look forward to investigating a number of issues as far as data breaches are concerned. The issues include: · Causes of data breaches. · How the data breaches are done. · Solution s to data breaches. Importance of the proposed research. With the continual technological advancements, I believe that if a large population of people as well as organizations that make use of technology to store their confidential data get to know all about these issues as well as how to combat data breaches, then the world would be a peaceful place to live in. it will also give room for further technological advancements as the more data secure people will be more willing to embrace the changes.

Running head: DATA INTEGRITY THREATS TO ORGANIZATIONS1 DATA INTEGRITY THREATS TO ORGANIZATIONS10 Data Integrity Threats To Organizations Student’s Name Institutional Affiliation Abstract The purpose of this paper is to define data integrity and to explain in detail its importance to any particular organization or enterprise. This paper goes into detail and discusses the main threats to data integrity which include cyber-attacks, transfer errors, human error, compromised hardware and malware. Solution s to these threats are also highlighted and the possible recommendations are given. The data collected for the purpose of this research paper came from questionnaires and literature reviews. The paper makes use of the qualitative research methodology based on the data collected from the questionnaires, literatures and interviews. Threats to data integrity are seen to have adverse effects on the productivity and profitability of many organizations. Data Integrity Threats To Organizations Introduction Data integrity is defined as the accuracy and consistency of data throughout its lifecycle. Data integrity is the core aspect of cyber security. It is important in the design, implementation and utilization of systems that process, store and retrieves data. There are many threats to data integrity and they include cyber-attacks, transfer errors, human error, compromised hardware and malware. Data integrity has a great impact to organizations in terms of its operations and decision making processes (Nedal & Sail, 2013). Data integrity is important to organizations in terms of productivity and operations since these activities rely on sound decision making processes made by the management based on real time data available to them. Inaccurate data based on data lacking data integrity has adverse effects on an organization progress since wrong organizational decisions would be made. It is therefore important for organizations to make data security a priority in their information systems. Organizations can prioritize data security by establishing cyber security teams or outsourcing the services to a third party who would protect and mitigate the threats associated to cyber security. Thesis Data integrity refers to the accuracy and consistency of data throughout its lifecycle and it can be compromised by threats such as human error, cyber-attacks, compromised hardware and malware. Importance of Data Integrity Data integrity is considered to be both a process and a state. As a state, data integrity can be both accurate and valid whereas as a process, data integrity is described as the measures taken to ensure that a data set or all the data in a database or construct is valid and accurate. It is important for organizations and enterprises to consider data integrity whether as a state or as a process because it ensures the traceability recoverability and searchability of data (Kavale, 2012). The validity and accuracy of data, which is essentia.

In a business projects What material is typically contained in a project report’s supporting appendices? Solution When writing a project report of a certain business project, all the material that is important to the discussion and findings of the conducted research are included in the main part, better known as the body of the paper. However, all the supplementary or supporting material of the research that was not essentially a part of the objective of the research work itself but played an important role in providing a comprehensive understanding of the research problem is included in the Appendix or Appendices. In other words, an appendix enhances the understanding of the readers or audience of the project report. Appendices can be used to include the process, method or the analysis you conducted before reaching onto the conclusion of the report. It can also include all the raw data and process flows that was used while conducting the research work. Providing proper nomenclature to the appendices is very important so that the reader clearly knows which appendix to refer to when reading a particular text of the project report. When a project report contains only a single appendix, it can be simply named as APPENDIX. But, when the project report contains multiple appendices, they can be titled as APPENDIX A, APPENDIX B, APPENDIX C, etc. The ordering of the appendices should be as per their appearance in the body of the report. When a project report does not contains an appendix or appendices, it may question the credibility of the project and doubt may arise in the minds of the reader of the project report whether the research work was authentic or comprehensively and sincerely conducted or not..

I would appreciate help with these 4 questions. Thank You. 1) Explain what the following are: root certificates, self-signed certificates. Describe how they are used. Provide some examples of each explaining how they are used. You should be able to find examples of each on your system by looking through various options available on your browser. 2) Provide a listing of the fields associated with a certificate of your choosing. Use the X509 definition to match the general fields of a certificate with the certificate you choose to look at. Describe each field. 3) Your manager is considering implementing a PKI infrastructure. They are considering using RSA encryption technology for the central part of their infrastructure. You manager would like to know some products or services that utilize RSA encryption technology. Provide three examples and explain how they make use of the RSA encryption technology. Provide a few original sentences describing each of your examples. 4) Compare the functionality offered by the RSA and Diffie-Hellman algorithms. Solution A Root SSL certificate could be a certificate issued by a trusty certificate authority (CA).In the SSL system, anyone will generate a language key and sign a replacement certificate therewith signature. However, that certificate isn\'t thought-about valid unless it\'s been directly or indirectly signed by a trusty CA.A trusty certificate authority is Associate in Nursing entity that has been entitled to verify that somebody is effectively World Health Organization it declares to be. so as for this model to figure, all the participants on the sport should agree on a group of CA that they trust. All operational systems and most of net browsers ship with a group of trusty CAs.The SSL system is predicated on a model of trust relationship, conjointly known as “chain of trust”. once a tool validates a certificate, it compares the certificate establishment with the list of trusty CAs. If a match isn\'t found, the shopper can then check to check if the certificate of the supplying CA was issued by a trusty CA, so on till the tip of the certificate chain. the highest of the chain, the basis certificate, should be issued by a trusty Certificate Authority. Self-signed certificates or certificates issued by a non-public CAs aren\'t appropriate to be used with the overall public.A certificate serves two essential purpose distribute the public key and verifying the individuality of the server so guests know they aren’t sending their information to the wrong person. It can only properly verify the identity of the server when it is signed by a trusted third party because any attacker can create a self-signed certificate and launch a man-in- the-middle attack. If a user just accept a self-signed certificate, an attacker could drop on all the traffic or try to set up an imitation server to phish additional information out of the user. Because of this, you will approximately on no account want to use a self signe.

I have a stack in Java populated with integers. I\'m trying to compare the elements in the stack to determine which is the largest. Basically, I enter the element at the top of the stack into e then pop each element off the stack and check to see if it is greater than the value stored in e. How can I check to see if the next element in the stack is greater than the element stored in e? E e = stk1.peek(); while(!stk1.empty()) { if(stk1.peek() > e) { e=stk1.peek(); } Solution Using recursive approach we can sort the stack and the top element of stack would be the largest integer. Algorithm: Sorting stack elements: Inserting elements in sorted order: Illustration: First pop all the elements from the stack and store poped element in variable \'temp\'. After poping all the elements function\'s stack frame will look like: Now stack is empty and \'insert_in_sorted_order()\' function is called and it inserts 30 (from stack frame #5) at the bottom of the stack. Now stack looks like below: Now next element i.e. -5 (from stack frame #4) is picked. Since -5 < 30, -5 is inserted at the bottom of stack. Now stack becomes: Next 18 (from stack frame #3) is picked. Since 18 < 30, 18 is inserted below 30. Now stack becomes: Next 14 (from stack frame #2) is picked. Since 14 < 30 and 14 < 18, it is inserted below 18. Now stack becomes: Now -3 (from stack frame #1) is picked, as -3 < 30 and -3 < 18 and -3 < 14, it is inserted below 14. Now stack becomes: Implementation: /** * Stack is represented using linked list */ public class Stack extends NativeClass { private final IntContainer data = new IntContainer(this, 1); private final Container> next = new Container>(this, 1){}; public int getData() { return data.get(); } public int setData(int newData) { return data.set(newData); } public Container getNext() { return next.get(); } public Container setNext(Container newNext) { return next.set(newNext); } public static Container nnc(Container orig) { return Container.nnc(new TypeInfo>(){}, orig); } /** * Utility function to initialize stack */ public static void initStack(Container[] s) { s[0] = null; } /** * Utility function to chcek if stack is empty */ public static int isEmpty(Stack[] s) { if(s == null) { return 1; } return 0; } /** * Utility function to push an item to stack */ public static void push(Container[] s, int x) { Container p = new Container(true, 1){}; p.get().setData(x); p.get().setNext(s[0]); s[0] = p; } /** * Utility function to remove an item from stack */ public static int pop(Container[] s) { int x; Container temp; x = s[0].get().getData(); temp = s[0]; s[0] = s[0].get().getNext(); nnc(temp).setNativeControlled(false); return x; } /** * Function to find top item */ public static int top(Stack[] s) { return s[0].getData(); } } // Recursive function to insert an item x in sorted way public static void sortedInsert(Container> s, int x) { // Base case: Either stack is empty or newly inserted // item is greater than top (more than all existing) if(is.

You are to simulate a dispatcher using a priority queue system in C++. New processes are to be entered using a GUI with priority included (numbering should be automatic). Processes are also to be terminated by GUI command. Context switches are to be by command with the cause of the switch being either a blocking call, time slice exceeded or termination. Assume only one CPU. Priorities and numbers of processes can be kept small, just big enough to demonstrate the required functionality. You may pre-populate the queues initially from a data file. I am looking at the mechanism as you are NOT creating actual processes, just simulating them. Functionality to be provided by you: 1. Priority based Ready Queue(s). 2. Blocked list. 3.

Write a program that accepts an arithmetic expression of unsigned integers in postfix notation and builds the arithmetic expression tree that represents that expression. From that tree, the corresponding fully parenthesized infix expression should be displayed and a file should be generated that contains the three address format instructions. This topic is discussed in the week 4 reading in module 2, section II-B. The main class should create the GUI shown below: Pressing the Construct Tree button should cause the tree to be constructed and using that tree, the corresponding infix expression should be displayed and the three address instruction file should be generated. The postfix expression input should not be required to have spaces between every token. Note in the above example that 9+- are not separated by spaces. The above example should produce the following output file containing the three address instructions: Add R0 5 9 Sub R1 3 R0 Mul R2 2 3 Div R3 R1 R2 Inheritance should be used to define the arithmetic expression tree. At a minimum, it should involve three classes: an abstract class for the tree nodes and two derived classes, one for operand nodes and another for operator nodes. Other classes should be included as needed to accomplish good object-oriented design. All instance data must be declared as private. You may assume that the expression is syntactically correct with regard to the order of operators and operands, but you should check for invalid tokens, such as characters that are not valid operators or operands such as 2a, which are not valid integers. If an invalid token is detected a RuntimeException should be thrown and caught by the main class and an appropriate error message should be displayed.

Why did the sovereign debt problem of Greece a country that accounts for less than 2 percent of euro area GDP threaten the banking system throughout the euro area? Solution Greece is the one of the most indebted nation. The Greek national debt is worth 320 billion euros ,or 175 per cent of GDP. The two third of this debt is owned to other countries and central banks in the Euro area. On the whole European countries have lent Greece 52.9 billion euros bilaterally, 130.9 billion through the EFSF and IMF has lent 25 billion euros. If problem in Greece increases , then it will default on all the above mentioned loans, which will be a situation of concern for all the European nations as they have lent a sizable chunk to Greece.

What is the theory of public debt management??? Solution 1. Sovereign debt management is the process of establishing and executing a strategy for managing the government\'s debt in order to raise the required amount of funding, achieve its risk and cost objectives, and to meet any other sovereign debt management goals the government may have set, such as developing and maintaining an efficient market for government securities. 2. In a broader macroeconomic context for public policy, governments should seek to ensure that both the level and rate of growth in their public debt is fundamentally sustainable, and can be serviced under a wide range of circumstances while meeting cost and risk objectives. Sovereign debt managers share fiscal and monetary policy advisors\' concerns that public sector indebtedness remains on a sustainable path and that a credible strategy is in place to reduce excessive levels of debt. Debt managers should ensure that the fiscal authorities are aware of the impact of government financing requirements and debt levels on borrowing costs.1 Examples of indicators that address the issue of debt sustainability include the public sector debt service ratio, and ratios of public debt to GDP and to tax revenue. 3. Poorly structured debt in terms of maturity, currency, or interest rate composition and large and unfunded contingent liabilities have been important factors in inducing or propagating economic crises in many countries throughout history. For example, irrespective of the exchange rate regime, or whether domestic or foreign currency debt is involved, crises have often arisen because of an excessive focus by governments on possible cost savings associated with large volumes of short-term or floating rate debt. This has left government budgets seriously exposed to changing financial market conditions, including changes in the country\'s creditworthiness, when this debt has to be rolled over. Foreign currency debt also poses particular risks, and excessive reliance on foreign currency debt can lead to exchange rate and/or monetary pressures if investors become reluctant to refinance the government\'s foreign-currency debt. By reducing the risk that the government\'s own portfolio management will become a source of instability for the private sector, prudent government debt management, along with sound policies for managing contingent liabilities, can make countries less susceptible to contagion and financial risk. 4. A government\'s debt portfolio is usually the largest financial portfolio in the country. It often contains complex and risky financial structures, and can generate substantial risk to the government\'s balance sheet and to the country\'s financial stability. As noted by the Financial Stability Forum\'s Working Group on Capital Flows, \"recent experience has highlighted the need for governments to limit the build-up of liquidity exposures and other risks that make their economies especially vulnerable to exte.
