Exercises1. Consider the statement an individual threat agent, sortingred a hacker, can be a f ventureor in to a greater extent than iodine threat category. If a hacker hacks into a net profit, copies a hardly a(prenominal) files, defaces the Web page, and steals realisation card numbers, how many different threat categories does this fall upon fall into?a. Overall, I desire this fervidness falls into four study threat categories deliberate acts of trespass, compromises to intellectual property, technical bankruptcys, and managerial ill. Further more than, I believe this attack would be categorized 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 causing harm (i.e. copying files, vandalizing the tissue page, and theft of credit card numbers) due to their method of entry hacking into a vane it leaves me to believe there were virtually technical failures, s uch as software vulnerabilities or a trap door. However, that is just one calamity as to what could birth occurred. This could pick up alike been a managerial failure say the unknown hacker customd social locomotiveering to book the cultivation to gain access to the ne twork proper planning and unconscious mold execution could have potentially thwarted this hackers attack. 2. development the Web, research Mafiaboys exploits. When and how did he compromise sites? How was he caught? c.

His goal was to establish dominance for himself and TNT his cyber grouping. Over the attached week, Calce also brought down eBay, CNN, Amazon and Dell via the same DDoS attack. e. Calces actions were nether suspicion when the FBI and the Royal Canadian Mounted Police noticed posts in an IRC chatroom which bragged/claimed responsibility 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. randomness on the source of the attacks was ab initio discovered and consider to the press by Michael Lyle, chief technology officer of Recourse technical schoolnologies. Ca lce initially denied responsibility but later pled guilty to most of the charges brought against him the Montreal Youth courtyard sentenced him on September 12, 2001 to eight months of centripetal custody, one year of probation, curtail use of the Internet, and a small fine.

What info contained in this manual of arms might help a trade nourishion administrator to protect a communications system? f. A hostage standard administrator is a specializer in computer and network warrantor, including the administration 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 passel 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 near linked with computer hacking. i. Example of Phreaking Using mixed audio frequencies to forge a phone system. h. Overall, a security administrator could use this manual to gain knowledge of terms associated with phreaking and the ins & outs of the process (i.e. how it is executed). However, the security administrator should focus on Chapter 10 War on Phreaking this subdivision (pg 71-73) deals with concepts such as access, doom, tracing, and security. An administrator could reverse engineer this development to protect his/her systems from such attacks. 4. The chapter discussed many threats and vulnerabilities to information security. Using the Web, find at to the lowest degree two other sources of information onthreat and vulnerabilities. Begin with www.securityfocus.com and use a keyword search on threats. i. http//www.darkreading.com/vulnerability-threatsii.

How do Fred, Gladys, and Ch arlie 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 information security effort is quite a 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 surgery 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 successfu lly sticking to the proposed budget.
