  • Operating system
  • Web software
  • Host device
  • Network

This ultimately implies that, a penetration test avails an tester the ability to exploit a weakness and potential security threats on a test network as a privileged user, during vulnerability assessments of the system.

<h3>The Network Mapper (Nmap) commands.</h3>

In this scenario, the Network Mapper (Nmap) commands that would be useful on this test network are:

  1. nmap xxx.xxx.x.x -p

16 (Stores 'a') 17 (Used as link)

18 (Stores 'r') 19 (Used as link)

20 (Stores 's') 21 (Used as link)

Numbers represented by circle are addresses of respective nodes. Here Front or Head has address 16. Which represents the Head Node.

Following image represents the word "smart" with respective nodes and their addressing.

​

Numbers represented by circle are addresses of respective nodes.

Describe one difference and one similarity between science and pseudoscience.
irakobra [83]
A scientific experiment is repeatable. Pseudoscience makes claims that cannot be either confirmed or denied. Both seem to want to explain our experiences and broaden our understanding. Science, as a working method, employs basic principles such as objectivity and accuracy to establish a finding. It often also uses certain admitted assumptions about reality, assumptions that must eventually support themselves and be proven, or the resulting finding fails verification. Pseudoscience, however, uses invented modes of analysis which it pretends or professes meet the requirements of scientific method, but which in fact violate it's essential attributes. Many obvious examples of pseudoscience are easy to identify, but the more subtile and herefore more insidious and convincing cases.
