Chapter 2 Exercises & Case Exercises Essay

Exercises1. Consider the statement an individual threat agent, like a hacker, can be a factor in more than wizard threat category. If a hacker hacks into a network, copies a few files, defaces the Web page, and steals credit card numbers, how many different threat categories does this try fall into?a. Overall, I deal this attack falls into four major threat categories deliberate acts of misdemeanor, compromises to intellectual property, skillful ruins, and managerial failure. Furthermore, I believe this attack would be reason as a deliberate act of theft/trespass which compromises intellectual property due to technical and managerial failures. b. It seems as this hacker was deliberately cause harm (i.e. copying files, vandalizing the web page, and theft of credit card numbers) due to their method of entry hacking into a network it leaves me to believe there were nearly technical failures, much(prenominal) as software vulnerabilities or a trap door. However, that is just o ne possibility as to what could have occurred. This could have also been a managerial failure say the unknow hacker used social engineering to obtain the information to gain access to the network proper planning and role execution could have potentially thwarted this hackers attack. 2. Using the Web, research Mafiaboys exploits. When and how did he compromise sites? How was he caught? c. Michael Demon Calce, also known as Mafiaboy, was a high school student from West Island, Quebec, who launched a series of highly bare DDoS (denial-of-service) attacks in February 2000 against large commercial websites including Yahoo, Fifa.com, Amazon.com, Dell, Inc., E*Trade, eBay, and CNN. Calce also attempted to launch a series of simultaneous attacks against nine of the thirteen root name servers. d. On February 7th, 2000, Calce targeted Yahoo With a project he named Rivolta meaning riot in Italian. This project utilized a denial of service cyber-attack in which servers commence overloaded with different types of communications, to thepoint in which they entirely shut agglomerate.Calce managed to shut down the multibillion dollar company and the webs top search engine for almost an hour. His goal was to establish dominance for himself and trinitrotoluene his cybergroup. Over the next week, Calce also brought down eBay, CNN, Amazon and Dell via the same DDoS attack. e. Calces actions were under suspicion when the FBI and the Royal Canadian Mounted Police notice posts in an IRC chatroom which bragged/claimed responsibleness for the attacks. He became the chief suspect when he claimed to have brought down Dells website, an attack not yet publicized at the time. schooling on the source of the attacks was initially discovered and reported to the press by Michael Lyle, chief technology officer of Recourse Technologies. Calce initially denied responsibility but later pled guilty to most of the charges brought against him the Montreal Youth Court sentenced him on Septe mber 12, 2001 to eight months of open custody, one year of probation, restricted use of the Internet, and a small fine. It is estimated that these attacks caused $1.2 billion dollars in global economic damages. 3. Search the Web for the The Official Phreakers Manual. What information contained in this manual of arms might help a gage administrator to protect a communications system? f. A security administrator is a specialist in computer and network security, including the ecesis of security devices such as firewalls, as well as consulting on general security measures. g. Phreaking is a slang term coined to describe the activity of a culture of people who study, experiment with, or explore telecommunication systems, such as equipment and systems connected to public telephone networks.Since telephone networks have become computerized, phreaking has become closely linked with computer hacking. i. Example of Phreaking Using various audio frequencies to manipulate a phone system. h. O verall, a security administrator could use this manual to gain knowledge of terms associated with phreaking and the ins & outs of the operation (i.e. how it is executed). However, the security administrator should focus on Chapter 10 War on Phreaking this section (pg 71-73) deals with concepts such as access, doom, tracing, and security. An administrator could reverse engineer this information to protect his/her systems from such attacks. 4. The chapter discussed many threats and vulnerabilities to information security. Using the Web, find at least two sassy(prenominal) sources of information onthreat and vulnerabilities. Begin with www.securityfocus.com and use a keyword search on threats. i. http//www.darkreading.com/vulner major power-threatsii. Dark Readings Vulnerabilities and Threats Tech Center is your resource for falling out news and information on the latest potential threats and technical vulnerabilities affecting todays IT environment.

The governments forensic investigation is wrestling with Snowdens apparent ability to defeat safeguards naturalised to monitor and deter people looking at information without proper permission. n. Deliberate acts of information extortionxi. Hackers claimed to have revealed the systems of the Belgian credit provider Elantis and threatened to cut confidential customer information if the intrust does not pay $197,000 before Friday, they said in a statement posted to Paste bin. Elantis confirmed the data breach Thursday, but the bank said it will not give in to extortion threats. xii. The hackers claim to have captured login credentials and tables with online loan applications which hold data such as full names, job descriptions, contact information, ID card numbers and income figures. xiii. According to the hackers the data was stored unprotected and unencrypted on the servers. To prove the hack, parts of what they claimed to be captured customer data were published. o. Deliberate acts of sabotage or vandalismxiv. Fired Contractor Kisses Off Fannie Mae With Logic Bomb xv. Rajendrasinh Babubha Makwana, a former IT contractor at Fannie Mae who was fired for making a coding mistake, was charged this week with placing a logic bomb within the companys Urbana, Md., data center in late October of last year. The malware was set to go into effect at 9 a.m. EST Saturdayand would have disabled internal monitoring systems as it did its damage. Anyone logging on to Fannie Maes Unix server network by and by that would have seen the words Server Graveyard appear on their workstation screens. p. Deliberate acts of theftxvi. Four Russian nationals and a Ukrainian have been charged with zip a sophisticated hacking organization that penetrated computer networks of more than a dozen major American and international corporations over seven years, stealing and selling at least 160 million credit and debit card numbers, resulting in losses of hundreds of millions of dollars. q. Deliberate software attacksxvii. China Mafia-Style Hack Attack Drives California steady to Brink xviii.

The attack began less than two weeks after Milburn publicly accused China of appropriating his companys parental filtering software, CYBERsitter, for a national Internet censoring project . And it ended unawares after he settled a $2.2 billion lawsuit against the Chinese government and a string of computer companies last April. xix. In between, the hackers assailed Solid Oaks computer systems, shutting down web and e-mail servers, spying on an employee with her webcam, and gaining access to sensitive files in a battle that caused company revenues to purl and brought it within a hairs breadth of collapse. r. Forces of naturexx. Websites Scramble As Hurricane Sandy Floods Data Centers xxi. The freak storm flooded data centers in New York City, taking down several major websites and services including The Huffington Post, Buzzfeed and Gawker that depended on them to run their businesses. xxii. Several websites stored their data at a lower Manhattan data center run by Datagram, whose basement was inundated with water during the storm, flooding generators that were intended to keep the power on. s. Deviations in quality of service from service providers xxiii. Chinas Internet hit by biggest cyberattack in its history xxiv.Internet users in China were met with sluggish response times early Sunday as the regions domain extension came under a denial of service attack. xxv. The attack was the largest of its kind ever in China, according to the China Internet net Information Center, a state agency that manages the .cn country domain. xxvi. The double-barreled attacks took place at around 2 a.m. Sunday, and then again at 4 a.m. The befriend attack was long-lasting and large-scale, according to state media, which said that service was slowly being restored. t.

SIM Cards Have Finally Been Hacked, And The Flaw Could Affect Millions Of Phones xxxii. After three years of research, German cryptographer Karsten Nohl claims to have finally found encoding and software flaws that could affect millions of SIM cards, and open up another route on mobile phones for surveillance and fraud.Case ExercisesSoon after the board of directors meeting, Charlie was promoted to Chief Information Security Officer, a new position that reports to the CIO, Gladys Williams, and that was created to provide leadership for SLSs feats to improve its security profile.Questions1. How do Fred, Gladys, and Charlie perceive the scope and scale of the new information security effort? a. Charlies proposed information security plan aims at securing business software, data, the networks, and computers which store information. The scope of the inform ation security effort is sooner vast, aiming at securing each vulnerability in addition to the aforementioned, the new information security plan also focuses on the companys staff. Since extra effort will be required to implement the new managerial plan and install new security software and tools, the scale of this operation is quite large. 2. How will Fred measure success when he evaluates Gladys performance for this project? How will he evaluate Charlies performance? b. Gladys is appointed as CIO of the team, which is gathered to improve the security of the company due to virus attack that caused a loss in the company I believe Fred will measure Gladys success by her ability to lead, keep the plan on track (i.e. time management) and successfully sticking to the proposed budget. Charlie was promoted to chief information security officer, a new position that reports to the CIO I believe Fred will measure Charlies success by his ability to implement the new plan, report his/their pr ogress and the overall success of the new system. 3. Which of the threats discussed in this chapter should notice Charlies attention early in his planning process? c. Portable Media Management (Ex. USB, DVD-R/W) should receive Charlies attention early in his planning process
