Hi,
Thank you for your response. While doing the Attack simulation, I was continously watching the SCSP EventViewer on the client where I saw the packets being Denied. Again, I am only using Windows Core Protection Policy with only one Network Defined under Allow List. Problem is, this will be installed on Public Web Server which would mean that I cannot use a limited set of allowed LANs. I do understand that HIPS would block any change to the registry, file or system which is great but they were expecting more sort of Network Protection similar to other firewalls where a pattern is recognized and blocked e.g. Syn, DOS, Brute Force etc.
Again, thank you for your answer. I am trying Metasploit right now. But please do add any more information that you might think, will be helpful for me.
