Identify the correct expansion of CNSS.

• Committee on National Security Systems

• Commission on National Security Solutions

• Council for National Systems Security

• Committee for National Secure Systems

List the three types of controls commonly used to secure databases.

• 
  Legal, operational, and financial controls

• External, internal, and automated controls
  

• Managerial, technical, and physical controls

• Manual, adaptive, and preventive controls

Explain why physical security alone is no longer sufficient for protecting networked information systems.

• Because traditional physical security tools cannot be used in cloud environments
  

• Because most organizations now outsource their IT infrastructure to third parties

• Because hardware components are becoming obsolete and need constant upgrades
  

• Because network connectivity introduces new security threats that require digital defenses like firewalls and intrusion detection systems
  

Discuss the importance of implementing multi-factor authentication in securing access to sensitive information.

• It simplifies the user experience by eliminating the need for passwords
  

• It is a legal requirement for all organizations
  

• It provides an additional layer of security beyond just passwords

• It reduces the need for strong passwords
  

What are the primary differences between symmetric and asymmetric encryption?

• Asymmetric encryption is used for data at rest, while symmetric is for data in transit
  

• Symmetric encryption is slower than asymmetric encryption

• Symmetric encryption uses a single key, while asymmetric uses a pair of keys
  

• Symmetric encryption is more secure than asymmetric encryption
  

What does the acronym DLP stand for in the context of data security?

• Data Lifecycle Policy

• Data Loss Prevention

• Data Leakage Protocol

• Digital Loss Protection

What are the key benefits of using a Virtual Private Network (VPN) for secure internet access?

• It improves internet speed by reducing latency
  

• It encrypts internet traffic to protect user privacy

• It allows users to bypass geographical restrictions on content
  

• It is a mandatory requirement for all online transactions
  

How does a firewall contribute to network security?

• By providing physical security to the server room
  

• By monitoring and controlling incoming and outgoing network traffic

• By ensuring all software is up to date
  

• By eliminating the need for antivirus software
  

What role does encryption play in protecting data during transmission?

• It speeds up the data transfer process
  

• It makes data unreadable to unauthorized users during transfer

• It ensures data integrity by preventing data loss
  

• It is only necessary for sensitive data, not all data
  

What are the main advantages of using end-to-end encryption for communication?

• It allows for faster communication speeds
  

• It ensures that only the communicating users can read the messages

• It eliminates the need for any authentication measures
  

• It is less expensive than traditional encryption methods
