A network administrator is configuring Neighbor Discovery Protocol in an IPv6 network to ensure an attacker cannot spoof link-layer addresses of network devices. Which of the following should the administrator implement?
A network administrator is configuring Neighbor Discovery Protocol in an IPv6 network to ensure an attacker cannot spoof link-layer addresses of network devices. Which of the following should the administrator implement?
To ensure an attacker cannot spoof link-layer addresses of network devices within an IPv6 network, the administrator should implement Router Advertisement Guard. This security feature protects against unauthorized or rogue routers by ensuring that only authorized routers can send router advertisements. By doing so, it prevents the injection of fake or malicious router advertisements which is crucial for protecting the integrity of the Neighbor Discovery Protocol in an IPv6 network.
It is B. Router Advertisement Guard is a security feature that protects against rogue router advertisements. It ensures that only authorized routers can send router advertisements on the network. By enabling Router Advertisement Guard, the administrator can prevent attackers from injecting fake or malicious router advertisements that could potentially lead to address spoofing.
Router Advertisement (RA) Guard is a network security feature used to protect against unauthorized or rogue routers in IPv6 networks.
shouldent it be A, its talking about the link-layer
MAC filter typically does not directly prevent spoofing of MAC addresses in NDP messages like Router Advertisement Guard does.
A is correct.
it shoud be a, its looking to protect the link layer
nvm is B
