ITN 260 Midterm Study Flashcards questions and answers well illustrated. Alex is working for Alpha Technology as a system administrator. The enterprise's sales team uses multiple external drives, often containing confidential data, that they carry between their offices and their clients' offices. What should Alex do to ensure that data is secure if it is stolen or lost, and why? - correct answers.Use encrypted USBs in the enterprise because they automatically encrypt the information and give Alex remote access to the drive to monitor and disable the user. Which function in cryptography takes a string of any length as input and returns a string of any requested variable length? - correct answers.Sponge ABC Enterprise is a global operation. As such, it needs to send regular, confidential messages and data between offices to communicate important market information, employee decisions, financial decisions, etc., for management consideration and senior-level decision making. Since these decisions impact the local employees and global businesses, they suspect that the data may be prone to attacks from threat actors internally and externally. While one of the senior systems administrators suggested implementing steganography to achieve this objective, the IT Department head at another branch suggested implementing cryptography. The management team has now called you for expert advice to select the best method to implement in the enterprise. What should your advice be, and why? - correct answers.Cryptography should be implemented because it allows information to be viewed only by authorized users and checks whether the information has been altered or changed by anybody. It also makes the information unclear, even if other users see it. Cryptography is a more advanced technology than steganography. These features make cryptography the right choice for the enterprise to implement. Which of the following statements describe a quantum computer? - correct answers.A quantum computer is a computer that relies on qubits that can be both 0 and 1 at the same time. Which encryption method in BitLocker prevents attackers from accessing data by booting from another OS or placing the hard drive in another computer? - correct answers.Full disk encryption Which encryption is a chip on the motherboard of a computer that provides cryptographic services? - correct answers.Trusted platform module Harry works at an automobile parts manufacturer. They sell these parts to retailers and deposit the proceeds in their bank. Using these funds, Harry pays the suppliers and employees. The Accounts Department maintains a ledger of all transactions of materials bought and sold. Similarly, the quality department and operations department also maintain a ledger of all transactions. Over the years, this process has become quite cumbersome, as growing data create confusion. Harry is looking at simplifying the process and has contacted you for a solution. Using which technology can this process be simplified and confusions avoided? - correct answers.Blockchain Which algorithm encrypts and decrypts data using the same key? - correct answers.Symmetric cryptographic algorithm Which encryption device you can use that has the following features? 1. It should allow administrators to remotely prohibit accessing the data on a device until it can verify the user status. 2. It can lock user access completely or even instruct the drive to initiate a self-destruct sequence to destroy all data. - correct answers.USB device encryption Wilson has requested your help to suggest an encryption method that will provide the highest security against attacks. Which encryption process should you suggest? - correct answers.AES (Advanced Encryption Standard) Which of the following best describes VBA? - correct answers.VBA is an event-driven programming language. During an interview, you are provided the following scenario:The enterprise that you recently joined is using the ISP DNS server to resolve domain names. You are asked which specific attack will need to be mitigated first to secure the enterprise network. Which of the following attacks should you choose? - correct answers.DNS hijacking Which of the following correctly differentiates between a man-in-the-middle (MITM) attack and a man-in-the-browser (MITB)? - correct answers.A MITM attack occurs between two endpoints, whereas a MITB attack occurs between a browser and underlying computer.
