"In computing, a firewall is a network security system that monitors and controls the incoming and outgoing network traffic based on predetermined security rules. A firewall typically establishes a barrier between a trusted, secure internal network and another outside network, such as the Internet, that is assumed to not be secure or trusted. Firewalls are often categorized as either network firewalls or host-based firewalls. Network firewalls are a software appliance running on general purpose hardware or hardware-based firewall computer appliances that filter traffic between two or more networks. Host-based firewalls provide a layer of software on one host that controls network traffic in and out of that single machine. Firewall appliances may also offer other functionality to the internal network they protect such as acting as a DHCP or VPN server for that network." [Firewall (computing). Wikipedia]
The cybersecurity diagram example "Firewall between LAN and WAN" was created using the ConceprDraw PRO software extended with the Network Security Diagrams solution from the Computer and Neworks area of ConceptDraw Solution Park.

The Network Security Diagrams solution presents a large collection of predesigned cybersecurity vector stencils, cliparts, shapes, icons and connectors to help you succeed in designing professional and accurate Network Security Diagrams, Network Security Infographics to share knowledge about effective ways of networks protection with help of software and network security devices of different cyber security degrees, Network Plans for secure wireless network, Computer Security Diagrams to visually tell about amazing possibilities of IT security solutions. The samples and examples reflect the power of ConceptDraw DIAGRAM software in drawing Network Security Diagrams, give the representation about variety of existing types of attacks and threats, help to realize their seriousness and the methods to deal with them.

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.

How to describe the necessity of using network security devices and visually illustrate this information? Now, it's very easy thanks to the ConceptDraw DIAGRAM diagramming and vector drawing software extended with Network Security Diagrams Solution from the Computer and Networks Area of ConceptDraw Solution Park.

Local area network (LAN). Computer and Network Examples

A local area network (LAN) is a devices network that connect with each other in the scope of a home, school, laboratory, or office. Usually, a LAN comprise computers and peripheral devices linked to a local domain server. All network appliances can use a shared printers or disk storage. A local area network serve for many hundreds of users. Typically, LAN includes many wires and cables that demand a previously designed network diagram. They are used by IT professionals to visually document the LANs physical structure and arrangement.
ConceptDraw - Perfect Network Diagramming Software with examples of LAN Diagrams. ConceptDraw Network Diagram is ideal for network engineers and network designers who need to draw Local Area Network diagrams.

Computer Network Diagrams

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

The Cisco Network Diagrams solution uses Cisco network symbols and Cisco icons to visualize computer networks. Cisco Network Topology is the arrangement of the Cisco symbols that display scheme of computer network.
Any Cisco equipment on the network are named like node. Network diagram topology commonly designed within connected nodes. Cisco icons are worldwide acknowledged and mainly established as standard icons for network diagrams. You may use them loosely, but you may not rework them.
The Cisco Network Diagram shows how signals act on the networked devices, or how data routes on the network from one device to the other. There are number of physical network typologies that engineers use while constructing computer networks.

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
