Encryption Concepts Flashcard

Front

What is the primary purpose of full disk encryption?

Back

To protect an entire storage device from unauthorized access.

Front

How does partition encryption differ from full disk encryption?

Back

Partition encryption secures a specific part of a disk rather than the entire disk.

Front

Which of the following is an example of file encryption? Encrypting the boot sector of a hard drive, Encrypting a PDF document with a password, Securing data transmitted over the internet, Encrypting database rows and columns

Back

Encrypting a PDF document with a password

Front

What is volume encryption primarily used for?

Back

Encrypting logical drives to protect all data stored within them

Front

Which of the following best describes database encryption? Options: Encrypting entire drives or logical volumes that store databases, Encrypting specific tables, columns, or rows within a database, Encrypting backup copies of a database, Encrypting user credentials only

Back

Encrypting specific tables, columns, or rows within a database

Front

Record encryption typically refers to: Encrypting a specific set of rows or entries in a database, Encrypting a volume containing database files, Encrypting network communications for database access, Encrypting entire disk partitions used by databases

Back

Encrypting a specific set of rows or entries in a database

Front

What is transport encryption designed to protect? Options: Files stored on an encrypted partition, Files while they are being transmitted over a network, Entire hard drives from being accessed without authorization, Passwords used to access encrypted volumes

Back

Files while they are being transmitted over a network

Front

Which of the following is a key difference between symmetric and asymmetric encryption? Symmetric encryption requires two different keys, while asymmetric uses one. Symmetric encryption uses one key for both encryption and decryption, while asymmetric uses two. Asymmetric encryption is only used for encrypting files, while symmetric is for databases. Symmetric encryption is more secure than asymmetric encryption.

Back

Symmetric encryption uses one key for both encryption and decryption, while asymmetric uses two.

Front

What is the role of a private key in asymmetric encryption?

Back

It is used to decrypt data encrypted with the corresponding public key.

Front

When should asymmetric encryption typically be used over symmetric encryption? Options: When encrypting large amounts of data quickly, When encrypting data for secure storage, When sharing encrypted data with someone else, When encrypting an entire disk or partition

Back

When sharing encrypted data with someone else
