What is the primary purpose of cryptography?
To create secret codes for historical documents
To control access to buildings and rooms
To encrypt or decrypt information for secure storage and transmission
To generate one-time passwords for authentication
Which encryption method uses the same key for both encryption and decryption?
Asymmetric key cryptography
Transposition
Symmetric key cryptography
Public-key encryption
What is the main difference between symmetric and asymmetric encryption?
Symmetric encryption is faster but less secure than asymmetric encryption
Asymmetric encryption uses the same key for both encryption and decryption
Symmetric encryption uses a pair of unrelated keys
Asymmetric encryption is more efficient for encrypting large blocks of data
Which encryption algorithm is commonly used in the electronic payment industry?
AES
RSA
3DES
Blowfish
What is the purpose of a virtual private network (VPN)?
To encrypt messages using the Caesar cipher
To control access to a building or system
To provide online privacy and anonymity by creating a secure connection
To generate one-time passwords for authentication
What does Physical Access Control primarily focus on?
Authenticating users
Restricting access to physical spaces
Managing data encryption
Monitoring network traffic
Which of the following is an example of Logical Access Control?
Security alarms
Motion detectors
Password-coded doors
Fob-controlled gates
What is the main purpose of Role-Based Access Control (RBAC)?
Controlling physical access
Assigning permissions based on job functions
Restricting access to network traffic
Implementing security audits
In the context of access control, what does Identification involve?
Checking user credentials
Determining access authorization
Tracing user activity
Establishing rules for security policies
What does Authentication, Authorization, and Accounting (AAA) primarily contribute to in network management and cybersecurity?
Physical access control
Managing data encryption
Screening users, enforcing policies, and auditing usage
Implementing security alarms
What is the primary purpose of data masking technology?
To replace sensitive information with random values
To encrypt all data in non-production environments
To dynamically mask data in production environments
To replace sensitive information with a non-sensitive version
Which data masking technique involves replacing data with authentic-looking values for anonymity?
Shuffling
Nulling out
Substitution
Obfuscation
What is the advantage of steganography over cryptography?
Steganography is more secure
Steganography attracts special attention
Steganography hides data in plain sight
Steganography requires a stego-key
How does LSB (Least Significant Bits) work in steganography?
It uses the most significant bits of each pixel
It changes all bits in an image
It changes bits only in the red color component
It uses bits of each pixel, making changes difficult to detect
What is the goal of steganalysis?
To hide information effectively
To detect hidden information
To encrypt data in plain sight
To create a stego-key
