Network Security

The Internet is a giant computer network which connects computers all over the world. It is integral part of human society and business. But the serious question for network engineers, designers, lawmakers and enforcers is the need for protect the Internet networks from the Internet crimes, hacking and attacks. There are quite a number of hardware, software and physical methods of protection against them. The samples you see on this page were created in ConceptDraw DIAGRAM using the tools of Network Security Diagrams Solution for ConceptDraw DIAGRAM software. They show protection networks with Firewalls and other network security devices.

Cisco Network Topology. Cisco icons, shapes, stencils and symbols

Cisco Network Topology represents the arrangement of worldwide recognized and standardized Cisco network symbols, icons, shapes, and stencils which help visualize the schemes of computer networks. Any equipment used in Cisco networks is also named a node and network topology diagram represents the scheme of connection the used nodes. Cisco Network Diagram illustrates how the signals enter on the networked devices and how the data spread within a network from one device to another. These diagrams are useful for engineers while constructing computer networks and working with them. Cisco Network Diagrams solution included to Computer and Networks area of ConceptDraw Solution Park contains quick-start templates, professionally designed samples and examples, and numerous libraries with a lot of predesigned vector design elements, icons, and shapes of Cisco equipment, components, devices, links which provide for ConceptDraw DIAGRAM users a perfect possibility of simple and quick drawing Cisco Network Diagrams and Schematics, Network Designs and Maps of any complexity.

Network infrastructure planning is a very important process in the network construction, and the share of time allocated to this within the scope of the entire project may reach 60-80%. A competent and thorough approach to planning contributes to the quick investment return, and also increases the reliability and flexibility of the final system, reducing the probability of additional costs related to the incorrect implementation. Any planning begins with an analysis of the business requirements to the final system. Basic network parameters, which should be assessed are the scalability, accessibility, cost, speed and safety. Speed and cost are often mistaken for the most important parameters, and the rest of the parameters aren't even remembered. This is not entirely correct. Initially, it is necessary to assess the business plans for the future, because sometimes it is more profitable to invest more money in the beginning. If the business is to develop, then, consequently, demands on

Hotel Network Topology Diagram

Network topology is a layout of various elements of computer network, such as nodes, links, routers, etc. It is a network topological structure which can be depicted logically or physically. Physical topology shows the physical location of network's components and cable connections between network nodes. Logical topology describes the data flows, the circulation of signals in physical topology. The physical and logical topologies for two networks can be identical, while their physical interconnections, the distances between nodes, transmission rates, and/or signal types may be differ. ConceptDraw DIAGRAM with Computer and Networks solution from Computer and Networks area of ConceptDraw Solution Park lets you design physical and logical network topology diagrams for wireless and wired computer communication networks located in various premises, including the hotels. You can easy design Hotel Network Topology Diagram, diagrams depicted LANs and WLANs, and also any of eight basic topologies (Point-to-point, Star, Bus, Mesh, Ring, Tree, Hybrid, Daisy chain).

Home area networks (HAN). Computer and Network Examples

A Home Area Networks (HAN) is a type of local area network that is used in an individual home. The home computers can be connected together by twisted pair or by a wireless network. HAN facilitates the communication and interoperability among digital devices at the home, allows to easier access to the entertainments and increase the productivity, organize the home security. This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the home network diagram.

AD LDS as a phone book service

This AD diagram example was created based on the picture "AD LDS as a phone book service" from the book "Active Directory for Dummies".
"Directory services are a great way of providing information that can be fre-
quently retrieved and searched on in a hierarchical way. ... Well, there’s no reason that you can’t create a directory service that’s actually a phone book. Imagine that you need to make a searchable phone directory of your organization available on the Internet. ... This isn’t a difficult task, but it has security repercussions. If you’ve already deployed AD DS and you have the employees’ phone numbers available in that directory, it might not be a good idea to expose your AD DS environment to the Internet for security reasons. Using AD LDS is a great alternative because it can be deployed separately from AD DS and it’s designed to simply provide the information retrieval service that you need without the complications involved with Kerberos authentication and group policies." [Steve Clines and Marcia Loughry, Active Directory® For Dummies®, 2nd Edition. 2008]
The Active Directory diagram example "AD LDS as a phone book service" 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.
