...CSEC630 Individual Assignment 1 Disclaimer/Caveat/Disclosure/Whateveryouwouldliketocallthis: You are more than welcome to use my paper below as a reference. But, please be smart and do not simply copy and paste because your Prof. or TA will know. Just like you, they have access to this website as well. So be nice and smart and don't set yourself up for a failure, at the very least you should rephrase/paraphrase/reword/Whateveryouprefertocallthis. Just a suggestion, but at the end of the day, it will be your decision. :) Also, I have got at the very least 90% in each of my papers, but that DOES NOT guarantee that you will get the same. It depends almost exclusively on how your professor looks at your response and how s/he grades. The ones that I got were awesome professors and my work and my points went across to them, hence the higher grade. So, basically what I am trying to say here is that if you score less than 90% while using my papers as reference or as a whole, don't curse me out, you just got a stricter professor. :) Operating System: An Operating System (OS) is an intermediary agent between the user and the computer hardware. The OS manages the computer’s resources (hardware, abstract resources, software), allocates the resources and control programs, to prevent errors and improper computer use. (Bower, 2009) Without an OS, a state of the art hardware can serve no purpose besides being a door stopper or a paper weight. Currently, OS comes in different...

...Lab Assignment #1: Introduction to Encryption Algorithms CSEC 630 University of Maryland University College Professor Jingyu Zhang 1. Which tool or technique would be most effective for a cryptanalyst to use to decipher a text encrypted with the Caesar cipher, and why? The best analysis tool to break the Caesar cipher is histogram because it performs a statistical analysis on cipher text which shows the frequency of each letter used in the file. This can later be compared and matched to the frequency of letters in the English language. 2. What do you notice about the histogram results when text is encrypted with the Vigenère cipher in comparison to the results of the Caesar cipher? Why is this the case? Histogram simply gives the frequency of each individual letter in cipher text without taking the plaintext into consideration. Since in Caesar cipher the relationship between plaintext and cipher text is one to one, histogram is more efficient to break the cipher. Since the key in vigenere is somewhat random the histogram shown below seems random as well. 3. There is an error in the following cipher text representation of this quote, what is it? The original unencrypted message is: TH ED IF FE RE NC EB ET WE EN ST UP ID IT YA ND GE NI US IS TH AT GE NI US HA SI TS LI MI TS The original encrypted message is: THE CORRECT CIPHERTEXT SD AH FO HL AR ST RE AS YL BS CI MQ TF NI VE TG HB SN QC NC SD TD HB SN QC DE CN IC IF OT IC This is the error example: SD...

...Q1. Which tool or technique from the above list would be most effective for a cryptanalyst to use to decipher a text encrypted with the Caesar cipher, and why? I personal like all the ways that I saw in the above list. I think that a cryptanalyst would likely to use the Histogram. I personally think it is easier to read and the information that it gives is very valuable. It gives you the frequency and percent on how many times a certain character was used. Which if I think if I was a cryptanalyst this may help me out in deciphering the encrypted text. Q2. What do you notice about the histogram results when text is encrypted with the Vigenère cipher in comparison to the results of the Caesar cipher? Why is this the case? I really don’t see too much change however, what I have noticed from the first histogram using Caesar cipher vs. using Vigenère I noticed that E is no longer the letter with the most characters used like it was in the Caesar cipher. As a matter of fact it is between L, and K and really doesn’t give a character to use to help decipher it. We know that the letter could be a J but how many words or even phases have a lot of Js in its message? It seems that Vigenere is the better and more difficult cipher to use. Q3. There is an error in the following ciphertext representation of this quote, what is it? What should the correct ciphertext be? (Hint: when using the CrypTool there are several ways to decode one that you can use is “Playfair” encipher...

...C:\snort\bin\ *.conf *.rules *.pcap dir PCAP file opened in Wireshark Wire shark TCP only filter Snort cmd run Alert file after modifying Snort rules. Renamed alert file. Alert 2 1. When running Snort IDS why might there be no alerts? There could be several different reasons for Snort not seeing any alerts. The number one reason, is that Snort has not been configured properly to listen for traffic. Snort needs to be configured properly on specific port for it too listen to traffic. Another reason according to the Snort FAQ, no alerts can be due to “the result of a checksum offloading issue.” (Snort FAQ, 2016) The use of –k none should be added in the cmd line to solve the issue of no alerts. 2. If you only went to a few web sites, why are there so many alerts? Snort is an open-source intrusion detection system (IDS). Intrusion detection systems are able to analyze many different types of network traffic to detect abnormalities. Snort analyzes packets on a network depending on the traffic traversing the network. Traffic can include TCP, UDP, and HTTP traffic to name a few. Depending on which protocols where used when going to the website, different types of alerts can be produced by Snort. 3. What are the advantages of logging more information to the alerts file? Advantages to logging more information to the alerts files is that one, it can be more useful to a system administrator trying to figure out what type of malware...

...Q1. Which tool or technique from the above list would be most effective for a cryptanalyst to use to decipher a text encrypted with the Caesar cipher, and why? The Histogram tool is the tool that will be most effective because it basically performs statistical analysis on the cipher text which basically shows the frequency at which each letter is used in a file or within the file. It can then be used for comparison and matching the frequency of the letters in the English language (Diffie,1996). Q2. What do you notice about the histogram results when text is encrypted with the Vigenère cipher in comparison to the results of the Caesar cipher? Why is this the case? The Caesar cipher was a lot easier to see the patterns of the alphabet. The frequency definitely made it easier to distinguish the usage pattern which makes it easier for decryption while the pattern is lost if it is viewed with the Vigenère. It will be easier to crack if the Caesar cipher is used compared to using the Vigenère which seems to be more difficult to crack. Q3. There is an error in the following ciphertext representation of this quote, what is it? What should the correct ciphertext be?

You are not required to use APA formatting. I expect the response to immediately follow the question as follows: 1. Describe… Response 2. Discuss… Response And so forth… ---------------------------------------------------------------------------------------------------------- FINAL EXAM ABC HEALTHCARE CASE BACKGROUND Healthcare companies, like ABC Healthcare, that operate as for-profit entities, are facing a multitude of challenges. The regulatory environment is becoming more restrictive, viruses and worms are growing more pervasive and damaging, and ABC Heathcare’s stakeholders are demanding more flexible access to their systems. The healthcare industry is experiencing significant regulatory pressures that mandate prudent information security and systems management practices. Furthermore, the continued pressure to reduce cost requires that management focus on streamlining operations, reducing management overhead and minimizing human intervention. The regulatory focus at ABC Healthcare is on the Health Insurance Portability and Accountability Act (HIPAA) and Sarbanes-Oxley (SOX). Both pieces of legislation highlight the need for good systems administration and controls, but focus on different aspects of the business. The main focus of HIPAA is to protect...

However, with the benefit of convenience of using EHRs, comes the responsibility of protecting electronic protected health information (ePHI) and safeguarding sensitive patient data. The Health Insurance Portability and Accountability Act (HIPAA) focuses on protecting ePHI with guidelines to ensure organizations have implemented “reasonable and appropriate” security measures to adhere to HIPAA rules and maintain patient confidentiality. HIPAA requires covered entities to conduct risk assessments to verify compliance and attempt to uncover areas where ePHI is at risk of...
