T+ Lesson 12

QuestionAnswer
algorithm A complex math formula applied to data to obscure it.
asymmetric-key cryptography Cryptography that involves a pair of keys: a public key for encryption and a private key for decryption.
BitLocker Microsoft Windows’ utility for encrypting an entire disk.
BCP Business continuity plan, a written plan that includes strategies for data restoration, prioritization, and restoring access after an incident that affects confidentiality, integrity, or availability.
BIA Business impact analysis, an assessment of the potential impact of the identified risks on critical business functions.
cipher text Encrypted, unreadable text
cryptography A secret code that protects data from unauthorized access by encrypting it.
data at rest Data that is being stored and not actively being used or transferred.
data backups Copies of data files to be used for recovery in case of data loss.
data in motion Data that is in transit between one location and another.
data in use Data that is being utilized by software, applications, or users.
data retention policy A policy that determines how long backup copies of data are kept.
decryption Reversing the encryption process so the data is once again readable.
disk encryption Encryption that secures an entire disk.
disaster recovery The process of bringing an organization back to normal functionality after a disrupting event or crisis.
encryption A method of turning readable data into unreadable data by running it through an algorithm.
fault tolerance The ability to keep the important functions operating in situations that might threaten continuity.
file encryption Encryption that applies to individual folders and files.
FileVault macOS’s utility for encrypting an entire disk.
GPG GNU Privacy Guard, an open-source alternative to PGP that provides end-to-end asymmetric encryption for email messages.
HTTPS HTTP Secure, a secure version of HTTP that uses either SSL or TLS cryptographic protocols.
IT contingency plan The section of a BCP that specifically addresses the recovery and continuity of the organization’s IT systems and services.
key The sequence of bits that is used as input to a cryptographic algorithm.
PGP Pretty Good Privacy, an end-to-end asymmetric encryption system for email messages.
plain text Unencrypted, readable text
redundancy Having extra or duplicate resources ready to put into service at a moment’s notice.
replication Creating and maintaining real-time or near-real-time duplicates of data across multiple locations or systems.
risk assessment An analysis of the potential threats and vulnerabilities that could impact operations.
S/MIME Secure/Multipurpose Internet Mail Extensions, a standard for email encryption and digital signatures that requires a digital certificate.
SSL Secure Sockets Layer, an older cryptographic protocol that is sometimes still used to secure HTTPS transmissions. It has been mostly replaced by TLS.
symmetric-key cryptography Cryptography in which the same key is used for both encryption and decryption.
TLS Transport Layer Security, a widely used encryption type for data exchanges between email servers and between web browsers and web servers. For HTTPS transactions, TLS replaces the older SSL.
UPS Uninterruptible power supply, a battery backup that can temporarily power an electrical device during a power outage.
VPN Virtual private network, a technology that creates secure and encrypted connections between an end-user device and a remote server.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
