Network Security Diagrams

This AD diagram example was redesigned from the picture "Single root domain with a structured OU model" from the book "Active Directory for Dummies".
"A domain is the cornerstone that you lay whenever you create trees and forests. Regardless of whether you design a tree or a forest, the starting point is always the root domain. The root domain is the first domain that you create in your AD structure, and it sits at the top of your diagram.
The root domain of your tree, similar to any other domain, is a grouping of
resources built on the following components:
(1) Domain controllers.
(2) Security policies. ...
For many small and medium-sized companies, a single root domain with a
structured OU (organizational unit) model... provides sufficient flexibility for an AD tree. ...
However, larger companies, companies with complex organization charts, and
companies with multiple sites often find that a single domain isn’t suitable." [Steve Clines and Marcia Loughry, Active Directory® For Dummies®, 2nd Edition. 2008]
The Active Directory diagram example "Single root domain with a structured OU model" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Active Directory Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park.

This VANET diagram example was drawn on the base of picture from the webpage "Security and Privacy in Location-based MANETs/ VANETs" from the Donald Bren School of Information and Computer Sciences, the University of California, Irvine. [ics.uci.edu/ ~keldefra/ manet.htm]
"A vehicular ad hoc network (VANET) uses cars as mobile nodes in a MANET to create a mobile network. A VANET turns every participating car into a wireless router or node, allowing cars approximately 100 to 300 metres of each other to connect and, in turn, create a network with a wide range. As cars fall out of the signal range and drop out of the network, other cars can join in, connecting vehicles to one another so that a mobile Internet is created. It is estimated that the first systems that will integrate this technology are police and fire vehicles to communicate with each other for safety purposes. Automotive companies like General Motors, Toyota, Nissan, DaimlerChrysler, BMW and Ford promote this term." [Vehicular ad hoc network. Wikipedia]

This example visual dashboard example shows website traffic metrics. Divided bar chart and pie chart are used to visualize compositional data. Scatter plot is used to visually analyse correlation between two data sets.
"Web traffic is the amount of data sent and received by visitors to a web site. ...
This is determined by the number of visitors and the number of pages they visit. Sites monitor the incoming and outgoing traffic to see which parts or pages of their site are popular and if there are any apparent trends, such as one specific page being viewed mostly by people in a particular country. There are many ways to monitor this traffic and the gathered data is used to help structure sites, highlight security problems or indicate a potential lack of bandwidth not all web traffic is welcome. Some companies offer advertising schemes that, in return for increased web traffic (visitors), pay for screen space on the site. Sites also often aim to increase their web traffic through inclusion on search engines and through search engine optimization." [Web traffic. Wikipedia]
