Cybersecurity Quiz Q2 Review

DES differs from Triple-DES in that:

• Triple-DES is slower but less secure

• DES is less secure due to shorter key length

• Triple-DES is a single round of encryption

• DES uses a longer key

Which of the following is a feature of AES?

• It is slower than DES

• It is primarily used for digital signatures

• It is a symmetric key algorithm

• It uses a 56-bit key

RSA encryption is based on:

• The simplicity of its algorithm

• The strength of symmetric key algorithms

• The speed of digital certificate verification

• The difficulty of factoring large primes

Digital certificates are important for:

• Providing a backup for encrypted data

• Storing large amounts of data

• Verifying the identity of entities

• Decreasing encryption time

Authentication in cybersecurity is:

• Encrypting user data

• Verifying user identity

• Granting user permissions

• Monitoring user activities

Which of the following is an authentication factor?

• Something you forget

• Something you borrow

• Something you predict

• Something you know

A common attack exploiting weak authentication is:

• Brute force attack

• Phishing

• DDoS attack

• SQL injection

The principle of least privileged access in authorization means:

• All users have equal access

• Users have temporary access

• All users have full access

• Users have no access unless necessary

Zero Trust security model differs from traditional models by:

• Verifying every request as if it originates from an open network

• Assuming all network requests are safe

• Not requiring any authentication

• Trusting all users inside the network

Phishing is:

• A type of virus

• Encrypting victim's data for ransom

• Deceiving users to reveal personal information

• Unauthorized access to data
