- Cryptography.arrow_forwardSeveral credit card firms now give users one-time-use credit card numbers as an extra layer of security for online purchases. There is just one purpose for these numerals. Customers may get the one-time-use number by visiting the website of the organization that issued their credit card. What are the advantages of employing this technology as opposed to more traditional methods of utilising credit card numbers? What are the advantages and disadvantages of employing this approach as opposed to using an electronic payment gateway for your own authentication?arrow_forwardWhy is hashing passwords preferable than encryption when keeping them in a secure location?arrow_forward
- What makes hashing passwords stored in a file superior to having an encrypted password database?arrow_forwardWhat Punishment for Webcam Spying is Appropriate? Microphones, digital cameras, and webcams have many practical and harmless uses. These technologies also can leave you open to spying. For example, one school district used software, which was supposed to track the school-distributed laptops in case of theft, to take photos and scree captures of students. In another instance, a person noticed that when she gave a customer service rep access to her computer, he turned on her webcam without asking for her permission. Cybercriminals can use spy tools take photos, or record video or audio, without turning on a light or other notification that indicates your camera or microphone is in use. The Flame virus is one way for spy tools to infect your computer. Security experts recommend using a sticker to cover your webcam and inserting a dummy plug in the microphone port when you are not using it. These technologies also allow people to take photos or videos in a public setting and share them…arrow_forwardDAC - Discretionary Access Control Bob is rather lazy and grants all his data access privileges (including grant) to Joe thinking he can avoid doing his work this way as Joe is less senior and would be reluctant to complain. Joe is not happy about this but is also sneaky, Joe hires someone with the moniker "IworkHARD4U" from a gig economy site he got an email from and sets them up with their own DB id "IworkHARD4" and grants them all the same privileges that Joe has, and backdoor into the company servers so they can do there work. Sounds legit huh? One day things go bad, Bob is afraid he will get caught in his work avoidance and quietly runs REVOKE Bobs_privilege_list ON * FROM Joe RESTRICT; To hide the trail he created. Note that this would show up in audit logs, backups, and other traces, but we never said Bob was bright. Bob notices that things are still changing in his tables and it is not his programs or himself that is changing them. So does his manager, he is not happy with…arrow_forward
