Information about an individual that identifies, links, relates, or describes them.
phishing
keylogging
personally identifiable information (PII)
malware
A technique that attempts to trick a user into providing personal information. That personal information can then be used to access sensitive online resources, such as bank accounts and emails.
phishing
keylogging
malware
rogue access point
The use of a program to record every keystroke made by a computer user in order to gain fraudulent access to passwords and other confidential information.
rogue access point
phishing
malware
keylogging
Software intended to damage a computing system or to take partial control over its operation.
phishing
keylogging
malware
rogue access point
A wireless access point that gives unauthorized access to secure networks.
rogue access point
malware
phishing
keylogging
A process of encoding messages to keep them secret, so only "authorized" parties can read them.
decryption
encryption
symmetric key encryption
asymmetric key encryption
A process that reverses encryption, taking a secret message and reproducing the original plain text.
encryption
public key encryption
symmetric key encryption
decryption
Pairs a public key for encryption and a private key for decryption. The sender does not need the receiver's private key to encrypt a message, but the receiver's private key is required to decrypt the message.
symmetric encryption
asymmetric encryption
encryption
decryption
the number of characters to shift the cipher alphabet
Morse Code
cipher
decrypt
key
The Caesar cipher is a _____________
substitution cipher
military-grade encryption
unbreakable code
very difficult to decode
Frequency analysis is
determining the % of time a letter appears in a given language
determining the % of times an encryption key is used
determining how often a Caesar cipher is repeated
a complex mathematical formula usually conducted using super computers
A cipher is _________________________.
a person who makes up secret codes
an algorithm that is used to scramble text so that it can be passed in secret
a lock that can be used to lock a message in a lock box
any puzzle, such as a crossword or Sudoku puzzle
A(n) ______ algorithm transforms cipher text to plain text.
Encryption
Decryption
In Cryptography, original message, before being transformed, is called
Simple Text
Plain Text
Cipher Text
Filled Text
In what way is multi-factor authentication (MFA) more secure than a password?
MFA ensures that users are using a very strong password.
MFA prevents the user from logging in over a rogue access point.
MFA encrypts the user authentication data during the login process.
MFA adds an additional level of security for an attacker to break through.
Which of the following best describes symmetric key encryption?
Uses different keys for encryption and decryption
Requires a public key for encryption
Uses the same key for both encryption and decryption
Does not require any key
Which of the following is an example of multi-factor authentication?
password + security question
username + password
encryption + certificate authority
IP address + password
A process that takes plain text and producing a secret message
symmetric encryption
encryption
decryption
asymmetric encryption
Which of the following best describes the process of decryption?
Creating a new encryption algorithm
Restoring cipher text back to its original plain text form
Scrambling data to prevent unauthorized access
Converting plain text into cipher text
