- Find an application in which a reliable Information Management System is needed. We must collect extremely sensitive information from our consumers and store it in our system. These details are submitted to us in electronic format. Even from ourselves, we must protect our consumers' secrecy; we must not see the information they present to us, otherwise the confidentiality will be jeopardised. As an information security officer, the duty is to double-check the validity of sensitive documents before storing them with the proper users. You have no access to the users' usernames and passwords, which you can save but not recover until the user gives you permission. Second, even though the whole database is compromised or robbed, you must encrypt the passwords and usernames to make it difficult for everyone to access them. (including server administrators) besides the users.Which cryptographic mechanisms, based on your knowledge of computer security, would you enforce in order to operate the…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…Find an application in which a reliable Information Management System is needed.

What makes this choice different from the others in the same field?A security policy is a document that provides employees with clear instructions about acceptable use of company confidential information, explains how the company secures data resources and what it expects of the people who work with this information. Most importantly, the policy is designed with enough flexibility to be amended when necessary. You are working in organization X, and you are supposed to develop an issue-specific security policy, you can pick one issue from Table.1 [1] (In the photos) Your Task is: To develop the different sections of your policy and adequate procedure(s), you can refer to SANS Policy Templates [2].

- Consider a scenario where an organisation implements a firewall as a safeguard mechanism to secure its internal network from external threats originating from the Internet. Is it advisable for all corporate workstations to be equipped with personal firewalls? Why? I'm sorry, I misunderstood your previous request. As an AI language model, I cannot add information to the user's text. However, I can help you rewrite it in an academic style. Please provide me with the original text.a. Intrusion detection is based on the assumption that the behavior of the intruder differs from that of a legitimate user in ways that can be quantified. Of course, we cannot expect that there will be a crisp, exact distinction between an attack by an intruder and the normal use of resources by an authorized user. This poses a challenge to the use of IDS. Briefly discus the challenges and propose a cure. b. Blockchain is a breakthrough technology that is expected to alter most industries in the coming years and it particularly touted so because of confidentiality, authentication and integrity that it offers which makes it independent, transparent and secure. Experts says that these important principles of security are achievable because blockchains employs hash functions and public key encryption. Briefly discuss how these cryptographic techniques offer confidentiality, authentication and integrity that gives blockchain its security.Is it possible for Eve's opponent to introduce system instability through a transparent Man-in-the-Middle attack? In this situation, how would you clarify it?
