Suppose Charlie had installed key logger software on all company computer systems and had made a copy of Peter's encryption key. Suppose that Charlie had this done without policy authority and without anyone's knowledge, including Peter's.
Would the use of such a tool be an ethical violation on Charlie's part? Is it illegal?
Suppose that Charlie had implemented the key logger with the knowledge and approval of senior company executives, and that every employee had signed a release that acknowledged the company can record all information entered on the company systems. Two days after Peter's call, Charlie calls back to give Peter his key: "We got lucky and cracked it early." Charlie says this to preserve Peter's illusion of privacy. Is such a "little white lie" an ethical action on Charlie's part?
Suppose that the IDS system examines each file that is downloaded. This IDS has a false alarm probability of 0.001. Suppose that on average, an employee downloads a file once an hour. If each alarm takes the IT team 2 hours to fully investigate, how bug does the IT team need to be for a 2000 employee company?
It was stated that there was a false positive as well as a false negative. Authentication methods that are based on a person's biometric traits may be distinguished. Why is the use of biometrics rather than passwords believed to be the more secure option? - Why? When employing a biometric method of authentication, is it still feasible to conduct fraud? Give it to me straight in your own words and I'll try to understand.

- Suppose, an organization is using RSA with modulus n and public exponent e. One day they are hacked, and their private key d becomes known to the attackers. Bob, the security consultant, suggests that instead of regenerating the new keys completely from the scratch, only the new exponents e’, d’ need to be re-computed, leaving the modulus n unchanged. Is this safe or not? Explain.arrow_forwardFor the Laplas Clipper malware, please write a short paragraph based on the given background and website info: - the date of the first incident’s report - How does it work, - How one should protect his/her system against this malware - If infected, how one can cope with that? Is there any solution? Laplas Clipper is a variant of information stealing malware which operates by diverting crypto-currency transactions from victims’ crypto wallets into the wallets of threat actors [1]. Laplas Clipper is a Malware-as-a-Service (MaaS) offering available for purchase and use by a variety of threat actors. It has been observed in the wild since October 2022, when 180 samples were identified and linked with another malware strain, namely SmokeLoader [2]. This loader has itself been observed since at least 2011 and acts as a delivery mechanism for popular malware strains [3]. SmokeLoader is typically distributed via malicious attachments sent in spam emails or targeted phishing campaigns but…arrow_forwardConsider the security flaw that was recently found in the system that manages authentication and access.

Choose an attack and explain how it works. Be sure to choose one that hasn’t been mentioned by another classmate. What countermeasures would you apply? How do the countermeasures you would use compare to those your classmates recommended for the attacks they chose? What do those similarities or differences tell you about fighting these types of attacks?arrow_forwardConsider a recent incident in the news involving a breach in authentication or access control.

- (2). Suppose that as part of Bob’s early (unsuccessful) experiment with cloud based surveys, the authentication system allows the user to attempt 100 passwords per second, but the user must wait for a 5 second lockout period, every 10 seconds. The password Bob used is 5 digits in length, only digits 0 – 9 inclusive allowed. a) Showing all steps, Calculate and show the total amount of time required for the attacker to guarantee to guess the password, including delays and actual guessing time. b) Bob eventually adjusted his authentication system to make it more difficult using hashing and other techniques, but then he realized that Malice has been capturing the hashed passwords sent from his laptop to the cloud server for authentication, to try to replay the hashes.
