  2. Enforcing strict access control policies

  3. Deploying intrusion detection and prevention systems

  4. All of the above


Correct Option: D
Explanation:

To mitigate the security risks associated with lack of isolation in 5G network slicing, a combination of countermeasures is required, including implementing strong encryption algorithms, enforcing strict access control policies, and deploying intrusion detection and prevention systems.

How does 5G network slicing impact the security of network management and orchestration?

  1. It increases the complexity of network management and orchestration, making it more vulnerable to attacks.
