several types of penetration testing. “An automated port based scan is generally one of the first steps in a traditional penetration test because it helps obtain a basic overview of what may be available on the target network or host. Port based scanners check to determine whether a port on a remote host is able to receive a connection. Generally‚ this will involve the protocols which utilize IP (such as TCP‚ UDP‚ ICMP‚ etc.)‚ However‚ ports on other network protocols could be present as well dependent

In this case‚ a thug generates a huge amount of ICMP ping requests (datagram) with fake source addresses and sends them to the IP broadcast address of a network‚ that is‚ remote LANs broadcast addresses. Then the routers/switch (layer 3) broadcasts these requests to layer 2 broadcast addresses. Most of the

1. What is the application ZenMap GUI typically used for? Describe a scenario in which you would use this type of application. It’s used for port scanning. It can be used to see what hosts are on the network and to see what services they are running. 2. What is the relationship between risks‚ threats and vulnerabilities as it pertains to Information Systems Security throughout the seven domains of a typical IT infrastructure? Threats and vulnerabilities lead risks‚ if you don’t have then then
