...------------------------------------------------- VULNERABILITES FACTING IT MANAGERS TODAY ------------------------------------------------- “THE HUMAN FACTOR” Alicia M. Frazier Abstract This paper will identify and give the proper knowledge about the single most important vulnerability that IT managers face today. It will provide significant evidence about reasons why it is the most vulnerable, its impacts on a organization, and how an organization can best address its potential impacts. “As human beings, we are vulnerable to confusing the unprecedented with the improbable. In our everyday experience, if something has never happened before, we are generally safe in assuming it is not going to happen in the future, but the exceptions can kill you and climate change is one of those exceptions”. -Al Gore What is Vulnerability? When you think of the word vulnerability what comes to mind? Although, definitions of Vulnerability may vary, Vacca (2013) defines the term as “an asset or a group of assets that can be exploited by one or more threats”. In the cyberworld vulnerability can be described as a weakness in a computer hardware or software, which could possibly become exploited. Most would consider vulnerability, as a threat as the approach in which vulnerability can be exploited through a potential cause of an incident. Today, processes and technology alone can’t assure a secure organizational...

...Introduction Cybercrime targets both government and private industries with various methods and motives behind them. Those various attack methods can make a significant damage ranging from an individual identity theft based scale to national scale concerning its security as a sovereign nation. In other words, cybercrime equally brings serious concerns for both private industries and government. Also, private industries have an interchangeable relationship with government agencies as client to provide services. Most of utilities-related critical infrastructure systems in every city are mostly managed by private organizations. As we are more depending on technological management of such critical infrastructure and centralization of such system throughout the network, cybercrime targeting those critical infrastructures can have detrimental effects for both private and government sectors. There has been a steady increase in numbers of cybercrime with its benefits over the traditional crime in the past decades. Cyber criminals are getting smarter and equipped with more resources with every passing days and are becoming bigger threats. Therefore, it is important to scrutinize those cybercrime-related issues as well as to delve into planning a well-thought out countermeasure for both private and government sectors in various aspects for betterment of safer society of the information era. In this paper, Part I addresses how government intervention justifies telling private industry...

"We reserve the right to use all necessary means—diplomatic, informational, military, and economic—as appropriate and consistent with applicable international law." Anderson, 2012 Hacker Culture and Mitigation: Nuclear Power Facility Introduction In the past few years cyber warfare has been at an all-time high. War is no longer just bombs and weapons, but targeting a nation’s critical infrastructure as a means to benefit the other. Lately the most valuable target has been Nuclear power facilities. The largest attack on a nuclear power facility started in 2006 when President Bush was in office. President Bush and the NSA named the attack code name: Olympic Games but was later named STUXNET after that bug had been found in 2010. At this point in time STUXNET has been the most powerful cyber-attack launched by the United States. For many years STUXNET was so sophisticated that it was able to target Iran’s...

Disruptions due to cyber-attacks are affecting the economy, costing companies billions of dollars each year in lost revenue. To counter this problem corporations are spending more and more on infrastructure and investing to secure the cyber security vulnerabilities which range anywhere from software to hardware to networks and people that use them. Due to the complexity of information systems that interact with each other and their counter parts, the requirement to meet specific cyber security compliances have become a challenging issues for security professionals worldwide. To help with these issues, security professionals have created different standards and frameworks over the years for addressing this growing concern of vulnerabilities within enterprise systems and the critical information they hold (“Critical Security Controls,” n.d.).

...1) Explain the two different types of attacks that can be performed in Cain and Abel to crack user account passwords. Which do you think is the most effective and why? For the assignment we utilized Cain & Abel password recovery tool for Microsoft Operating Systems. For this lab assignment we utilized Brute Force NT LAN Manager (NTUM) and LAN Manager (LM) and Dictionary NTLM and LM hashes. (Features overview, n.d.) Brute Force is a password cracking -technique that tries every combination of numeric, alphanumeric, and special characters until the password is broken or the user is locked out. Dictionary is a technique that runs a given password against each of the words in a dictionary (file of words) until a match is found or the end of the dictionary is reached. (p. 13) Cain and Abel couples Brute Force and Dictionary with LM and NTLM hash. Based on my lab experience, my assessment is that the Dictionary NTLM Manager is the better of the processes. The table below reveals that Dictionary NTLM delivered more favorable results over LM because this process uncovered the passwords in the shortest amount of time and recovered the passwords in their entirety. Table | Brute Force LM | Brute Force NTLM | Dictionary LM | Dictionary NTLM | User1 | No password, 6-8 hours | No password, estimated time 10 years | yes, 75 seconds | yes, 40 | User2 | No password, 6-8 hours | No password, estimated time 10 years | yes, 30 | yes, 25 | User3 | No password, 6-8 hours...

...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...

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.

...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...
