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 through a better course of action? 6. What additional information, if any, would help you answer the previous questions?

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.

Which statement reflects a legitimate benefit of phishing? A. B. C. D. Question options: a. Use spear phishing because someone will likely click a malicious link if a generic email is sent to every user. b. Use voice phishing because people tend to place more trust in those they can have a real-time conversation with. c. Use SMS phishing because smartphones tend to have trusted access to company trade secrets. d. Use whaling because the largest number of people can be reached by mass email
An attacker must do what must be done to make a sniffer attack successful. If an attacker gains access to the network, it is unclear how they may make use of the sniffer system.
Need the below questions answered: 1) Suppose that a merchant’s website stores hashed passwords that have not been salted. Describe an attack to obtain passwords that could be prevented using salted passwords. (Remember, hashes cannot be "decrypted") 2) You know that it is generally not a good practice to create your own authentication systems when standard packages are available to you. But for the purposes of learning, you are doing it anyway. You are trying to decide which hashing algorithm to use when salting and hashing user passwords for the webapp you are building. Of the following hashing algorithms, which is best for hashing passwords? What makes your choice the best option for this scenario? SHA512 MD5 Bcrypt SHA256 3) There are several options for password hashing algorithms other than your choice from above. Do a little Internet investigation and discuss an equivalent or better option than your previous choice. Are there any parameters or settings to that algorithm…
Consider the following scenario: you get a message from your company's mail server informing you that the password for your account has been changed and that you must confirm the change. According to what you know, you have not altered the password! What may have motivated the password change, and how did it happen? Was it a virus, and if so, on which computers, that may have given an attacker with the information they needed to successfully reset the password?
Give some examples of the many means through which a session may be taken over by an attacker. The question is how one would protect oneself against such an attack.
Suppose a user employs one-time passwords as above (or, for that matter, reusable passwords), but that the password is transmitted sufficiently slowly. (a) Show that an eavesdropper can gain access to the remote server with a relatively modest number of guesses. (Hint: The eavesdropper starts guessing after the original user has typed all but one character of the password.) (b) To what other attacks might a user of one-time passwords be subject?
How can you be sure that every computer in an IPsec network uses its own private key pair?
Authorization lists should be encrypted and secured since they are so vulnerable to manipulation. Imagine if someone messed with these files without meaning to.
Is there a specific protocol that is especially vulnerable to assault since so many people depend on it?
What happens if an attacker tries to tamper with the Tag (the MAC) and the ciphertext while they are in transit when a message authentication code (MAC) is being used? Give an explanation as to why this attack can never be successful, given that the ability of the target to identify a tampered Tag/ciphertext ensures that it will succeed every time.
