In the case of the diagram E-1‚ there are many problems like this that can cause the network to not perform the way it is supposed to. Some of these problems include the IP addresses‚ subnet masks‚ and default gateways in this network. All of these things need to be correct and working

Network Security Some DoS attacks can be avoided by applying vendor patches to the software that has been compromised. Another way to deal with DoS attacks in the case of an attack coming from a number of known IP addresses is to put up a rule to drop all incoming traffic from those known attackers. Yet another way to deal with these types of attacks is to set up packet filters. This will act as a proxy for connections. Once the handshake is validated it will be forwarded to the correct destination
