Which of the following is a key security feature of 5G networks?

  1. End-to-end encryption

  2. Network slicing

  3. Software-defined networking

  4. Virtualization


Correct Option: A
Explanation:

End-to-end encryption ensures that data is protected from eavesdropping and tampering throughout its transmission from the source to the destination.

What is the purpose of network slicing in 5G networks?

  1. To improve network performance

  2. To enhance security

  3. To support multiple applications with different requirements

  4. To reduce latency


Correct Option: C
Explanation:

Network slicing allows network operators to create multiple virtual networks on a single physical infrastructure, each with its own unique security and performance characteristics.

Which authentication protocol is commonly used in 5G networks?

  1. WPA2

  2. EAP-SIM

  3. 802.1X

  4. TLS


Correct Option: B
Explanation:

EAP-SIM (Extensible Authentication Protocol - Subscriber Identity Module) is a widely adopted authentication protocol for 5G networks, providing strong mutual authentication between devices and the network.

What is the role of the 5G Authentication Center (5G-AC) in the authentication process?

  1. To generate and distribute authentication keys

  2. To verify the identity of devices

  3. To maintain a database of authorized devices

  4. To manage network access policies


Correct Option: A
Explanation:

The 5G-AC is responsible for generating and distributing authentication keys to devices, ensuring secure communication between devices and the network.

Which security mechanism is used to protect the integrity of signaling messages in 5G networks?

  1. Integrity Protection (IP)

  2. Confidentiality Protection (CP)

  3. Replay Protection (RP)

  4. Forward Secrecy (FS)


Correct Option: A
Explanation:

Integrity Protection (IP) is a security mechanism that ensures the integrity of signaling messages by detecting and preventing unauthorized modifications.

What is the purpose of the 5G Security Edge Protection Proxy (SEPP)?

  1. To protect against DDoS attacks

  2. To prevent unauthorized access to the network

  3. To enforce network access policies

  4. To detect and mitigate security threats


Correct Option: D
Explanation:

The 5G SEPP is a security gateway that detects and mitigates security threats by analyzing network traffic and identifying malicious activities.

Which security protocol is used to establish a secure connection between a 5G device and the network?

  1. IPsec

  2. TLS

  3. IKEv2

  4. SSH


Correct Option: C
Explanation:

IKEv2 (Internet Key Exchange version 2) is a security protocol that establishes a secure connection between a 5G device and the network by negotiating and exchanging cryptographic keys.

What is the role of the 5G Network Exposure Function (NEF) in network security?

  1. To detect and respond to security incidents

  2. To manage and enforce network access policies

  3. To collect and analyze network traffic data

  4. To generate and distribute security certificates


Correct Option: C
Explanation:

The 5G NEF collects and analyzes network traffic data to identify security threats and anomalies, enabling network operators to detect and respond to security incidents.

Which security mechanism is used to protect the confidentiality of user data in 5G networks?

  1. End-to-end encryption

  2. Network slicing

  3. Software-defined networking

  4. Virtualization


Correct Option: A
Explanation:

End-to-end encryption ensures that user data is encrypted throughout its transmission from the source to the destination, protecting it from eavesdropping and unauthorized access.

What is the purpose of the 5G Security Policy Control Function (SPCF)?

  1. To manage and enforce network access policies

  2. To detect and mitigate security threats

  3. To collect and analyze network traffic data

  4. To generate and distribute security certificates


Correct Option: A
Explanation:

The 5G SPCF manages and enforces network access policies, ensuring that only authorized devices and applications can access the network.

Which security mechanism is used to protect against replay attacks in 5G networks?

  1. Replay Protection (RP)

  2. Forward Secrecy (FS)

  3. Integrity Protection (IP)

  4. Confidentiality Protection (CP)


Correct Option: A
Explanation:

Replay Protection (RP) is a security mechanism that prevents attackers from replaying previously captured messages, ensuring the freshness and integrity of network communications.

What is the role of the 5G Security Credential Management Function (SCMF)?

  1. To generate and distribute security certificates

  2. To manage and enforce network access policies

  3. To detect and mitigate security threats

  4. To collect and analyze network traffic data


Correct Option: A
Explanation:

The 5G SCMF generates and distributes security certificates to devices and network components, enabling secure communication and authentication.

Which security mechanism is used to protect against man-in-the-middle attacks in 5G networks?

  1. Forward Secrecy (FS)

  2. Integrity Protection (IP)

  3. Confidentiality Protection (CP)

  4. Replay Protection (RP)


Correct Option: A
Explanation:

Forward Secrecy (FS) is a security mechanism that ensures that compromised session keys cannot be used to decrypt previously recorded communications, protecting against man-in-the-middle attacks.

What is the purpose of the 5G Security Management Function (SMF)?

  1. To manage and enforce network access policies

  2. To detect and mitigate security threats

  3. To collect and analyze network traffic data

  4. To generate and distribute security certificates


Correct Option: A
Explanation:

The 5G SMF manages and enforces network access policies, ensuring that only authorized devices and applications can access the network.

Which security mechanism is used to protect against eavesdropping in 5G networks?

  1. Confidentiality Protection (CP)

  2. Integrity Protection (IP)

  3. Replay Protection (RP)

  4. Forward Secrecy (FS)


Correct Option: A
Explanation:

Confidentiality Protection (CP) is a security mechanism that encrypts data in transit, preventing unauthorized parties from eavesdropping on network communications.
