What is Ping of Death Assault?

Ping of death is a strategy for DoS Denial of Service assault. It’s an attack-type that objectifies the ICMP Internet Control Message Protocol and the TCP Transmission Control Protocol, and is quite possibly the most undermining of all ICMP attacks. The ping of death attack is otherwise called a...

Network policy may be bypassed by some ICMP Echo Requests

Impact Under certain conditions, ICMP Echo Request sent to a Cilium endpoint from an actor may bypass a network policy which disallows access from the actor to the endpoint, but allows from the endpoint to the actor. This does NOT apply to UDP and TCP traffic. The actor is either a pod or a clust...
