A cloud operations team is implementing a new virtual network for a highly sensitive application. To prevent IP address spoofing and ensure that virtual machines (VMs) only send and receive traffic using their assigned IP addresses, a specific network security feature needs to be enabled at the virtual network interface level. Which feature directly addresses this concern?
- ANetwork Access Control Lists (NACLs)
- BIP Spoofing Protection
- CPrivate IP Address Auto-Assignment
- DVPC Flow Logs
Show answer & explanationAnswer & explanation
Correct answer: B. IP Spoofing Protection
IP Spoofing Protection, often implemented as a setting on the virtual network interface, prevents a VM from sending or receiving traffic with an IP address it is not legitimately assigned, thereby mitigating spoofing attacks.
Why the other options are wrong
- A. NACLs filter traffic based on rules but do not inherently prevent a VM from attempting to spoof an IP address.
- C. Private IP Address Auto-Assignment is a convenience feature for IP management, not a security control against spoofing.
- D. VPC Flow Logs monitor traffic but do not prevent spoofing.
Cloud IP Spoofing Protection
A cloud network security feature that prevents a virtual machine from sending or receiving network traffic with an IP address that is not legitimately assigned to its network interface.
- Protects against unauthorized use of IP addresses.
- Typically configured at the virtual network interface level.
- Enhances network integrity and prevents impersonation.
Memory trick: To stop network pretenders (spoofing), you need a strict ID check. IP SPOOFING PROTECTION acts like a bouncer at the network interface, only allowing traffic with the correct, assigned ID.
