Ron has configured his network to provide strong perimeter security. As part of his network architecture, he has included a host that is fully exposed to attack. The system is on the public side of the demilitarized zone, unprotected by a firewall or filtering router. What would you call such a host?

How would you describe an attack where an attacker attempts to deliver the payload over multiple packets over long periods of time with the purpose of defeating simple pattern matching in IDS systems without session reconstruction? A characteristic of this attack would be a continuous stream of small packets.
Unauthorized users are still able to connect to the wireless network. Why do you think this is possible?
In an attempt to secure his wireless network, Bob turns off broadcasting of the SSID. He concludes that since his access points require the client computer to have the proper SSID, it would prevent others from connecting to the wireless network. Unfortunately unauthorized users are still able to connect to the wireless network. Why do you think this is possible?
which is based on the European Institute for Computer Antivirus Research format that can be detected by the AV
You have installed antivirus software and you want to be sure that your AV signatures are working correctly. You don’t want to risk the deliberate introduction of a live virus to test the AV software. You would like to write a harmless test virus, which is based on the European Institute for Computer Antivirus Research format that can be detected by the AV software.
How should you proceed?
Why does the host respond to hping2 and not ping packet?
You ping a target IP to check if the host is up. You do not get a response. You suspect ICMP is blocked at the firewall. Next you use hping2 tool to ping the target host and you get a response. Why does the host respond to hping2 and not ping packet?

Which port does SMB over TCP/IP use?
NetBIOS over TCP/IP allows files and/or printers to be shared over the network. You are trying to intercept the traffic from a victim machine to a corporate network printer. You are attempting to hijack the printer network connection from your laptop by sniffing the wire.

If Lori is supposed to scan all known TCP ports, how many ports should she select in the software?
Lori has just been tasked by her supervisor toonduct vulnerability scan on the corporate network.She has been instructed to perform a very thorough test of the network to ensure that there are no security holes on any of the machines.Lori’s company does not own any commercial scanning products, so she decides to download a free one off the Internet.Lori has never done a vulnerability scan before, so she is unsure of some of the settings available in the software she downloaded.One of the options is to choose which ports that can be scanned.Lori wants to do exactly what her boss has told her, but she does not know what ports should be scanned.
