- In the context of information security, the principle of 'need-to-know' is one of the most important ones to consider. What does the principle of 'need-to-know' implies? * Critical tasks can only be completed by at least two individuals, so that collusion is needed to be able to commit fraud. Users should have access to only the information that is needed to perform their tasks. Users should be assigned with a minimum level of access rights to perform their tasks. O Users should be assigned only temporary access rights to perform their tasks.Denial of Service attacks are estimated to happen once every six months (twice a year) in a mid-size company. One such company, XYZ, estimates the cost of recovering from a single DoS attack to be $12000. The company decides to apply a number of controls to counter these attacks. With these controls, the frequency of successful DoS attacks against the company reduces to once a year and the cost of recovering from an instance becomes $8000. The cost of implementing these controls is $7,000 a year. The annual loss expectancy (ALE) without controls is $ A . The annual loss expectancy (ALE) with controls is $Denial of Service attacks are estimated to happen once every six months (twice a year) in a mid-size company. One such company, XYZ, estimates the cost of recovering from a single DoS attack to be $12000. The company decides to apply a number of controls to counter these attacks. With these controls, the frequency of successful DoS attacks against the company reduces to once a year and the cost of recovering from an instance becomes $8000. The cost of implementing these controls is $7,000 a year. From a purely financial point of view, is it worth for the company to implement these controls? Calculate the prior and post ALE and do a cost-benefit analysis to answer the question. In your answer make sure that you indicate what ARO, SLE and ALE are with and without controls. State clearly whether the company should implement the controls and explain why.
- Scenario 2 An organization dedicated to reducing spam tries to get Internet service providers (ISPS) in an East Asian country to stop the spammers by protecting their mail servers. When this effort is unsuccessful, the anti-spam organization puts the addresses of these ISPS on its "black list." Many ISPS in the United States consult the black list and refuse to accept email from the blacklisted ISPS. This action has two results. First, the amount of spam received by the typical email user in the United States drops by 25 percent. Second, tens of thousands of innocent computer users in the East Asian country are unable to send email to friends and business associates in the United States. Questions 1. Did the anti-spam organization do anything wrong? 2. Did the ISPS that refused to accept email from the black listed ISPS do anything wrong? 3. Who benefited from the organization's action? 4. Who was hurt by the organization's action? 5. Could the organization have achieved its goals…3. Access control is one of the security approaches that enable an organization to restrict access of its group of users to information or tangible assets. a) Explain any TWO (2) the importance of access control implementation in an organization. b) Describe THREE (3) principles required to apply the access control. c) By considering Uniec Campus System, why a different group of users such as student and lecturer are assigned with different access rights to the same information such as coursework?Provide an example of a situation in which one of the four different methods of access control may be put into practice. What makes this choice different from the others that are available in this category?
- One common description of the security issue (from the perspective of the defender) is the preservation of the confidentiality, integrity, and availability of data (and services). From the attacker's point of view, it is possible to conceive about interruption, interception, modification, and creation in many ways. Is there any relationship between the last four ideas and the first three concepts mentioned? Is there a match-up between any of the four and any of the other three players? If so, does one or more of the four include at least one of the three? Is there anything that comes within the purview of one formulation but not the other, and vice versa? Which framework is more advantageous, and why is this so?Question: Consider an automated teller machine (ATM) in which users provide a personal identification number (PIN) and a card for account access. Give examples of confidentiality, integrity, and availability requirements associated with the system and, in each case, indicate the degree of importance of the requirement.(Every aspect (degree of importance, examples etc) need to be addressed)Two new computer codes are being developed to prevent unauthorizedaccess to classified information. The first consists of six digits (each chosenfrom 0 to 9); the second consists of three digits (from 0 to 9) followed by twoletters (A to Z, excluding I and O).(i) Which code is better at preventing unauthorized access (defined as breaking the code in one attempt)?(ii) If both codes are implemented, the first followed by the second, what isprobability of gaining access in a single attempt?
- To complete this assignment, you will need to do some research and produce a report that addresses the following issues regarding digital fingerprinting: You should concentrate on the following issues: What exactly is Digital Fingerprinting, and why is it employed in the first place? What is the operation of the fingerprinting algorithm? Explain how it works on a fundamental level. To achieve the intended result—either blocking, deleting, or authorizing the use of content—a series of actions must be taken. Fingerprinting, according to several cybersecurity experts, is abusive and exposes users' privacy concerns. Some browsers have included specific methods to prevent browser fingerprinting from occurring. Describe the safeguards used by any of the browsers to protect themselves against fingerprinting. List two common Fingerprinting Algorithms that are used nowadays.Let's look at an example of when the full denial of services caused a problem for the user (the user gets no response from the computer). Another scenario in which a 10 percent denial of service (that is, the user's calculation continues, but at a pace 10 percent slower than normal) represents a significant issue for that user is described below. Illegal access to a computer system may result in a 10% denial of service to the system's legitimate users. If this is the case, what steps would you take?It is important to compile a list of all known hazard categories and rank them according to the frequency with which they occur, preferably with URL proof.
