Security 6.6 Flashcards
Plain Text
unencrypted message
Cipher Text
an encrypted message
*Uses an algorithm to encrypt or decrypt a message.
Not encryption!!!!!!
Data at rest
Data that is in some sort of persistent storage media.
Ex. whole disk, mobile device, database, file-to-folder.
Data in transit (MOTION)
state when data is transmitted over a network, such as communicating with a web page vis HTTPS or sending an email.
EX. SSL/TSL, (think transport encryption)
Mobile Device Encryption
100% always encrypted.
V.P.N.
Virtual Private Network
connects a remote host with a internet connection to private local network.
Uses encryption and connect protocols to create a tunnel that is secure.
What type of encryption is used by mobile applications to encrypt data in-transit?
Public Key Infrastructure (PKI)
Public Key Infrastructure PKI
implementation of asymmetric encryption used by mobile applications for encrypting data in-transit.
(users or server computers use validation by a Digital Certificate)
What type of threat does disk-level encryption protect against?
Information snooping after the theft of a laptop
Disk-level encryption
technique the encrypts the entire contents of a hard drive.
disk-level encryption only protects data at-rest!!!!
What type of network uses tunneling to encrypt data, protecting communications between two endpoints sent through a public network?
A Virtual Private Network (VPN)
What option on iOS protects email and other apps’ data at-rest by using encryption?
The “Data Protection” option
What type of encryption is used by mobile applications to encrypt data in-transit?
Public Key Infrastructure (PKI)
A user wants to transmit a sensitive file via an unsecure method such as email. What technique would you recommend?
Using file-level encryption
Fault Tolerance
systems that contain additional components to help avoid a “single point of failure.”
