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.

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

Local Area Network (LAN) is a network which consists of computers and peripheral devices connected each other and to the local domain server, and covers a little territory or small number of buildings, such as home, school, laboratory, office, etc. LAN serves for few hundreds of users. It includes many cables and wires, and demands to design previously a Network diagram. All local area network devices can use the shared printers and disk storage. ConceptDraw DIAGRAM is a perfect network diagramming software with examples of LAN Diagrams, templates and predesigned vector objects. ConceptDraw DIAGRAM is the ideal choice for network engineers and network designers who need to draw fast and easy Local Area Network Diagrams, for IT specialists, developers and other IT professionals which need to visualize the communication schemes of LAN and visually document the LAN's physical structure and arrangement in houses, offices and other buildings. Ready-to-use vector objects from Computer Network Diagrams solution will help you design LAN diagrams in minutes.

"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.

Campus Area Networks (CAN). Computer and Network Examples

Campus Area Network (CAN) is a computer network which provides wireless access to the Internet or LAN for the users located in two or more buildings on the limited geographical area, or in the open space surrounding these buildings. Campus Area Network is usually set in campus of a university or college, but the same kind of planning and design can be applied for other purposes, for enterprises, office buildings, military bases, industrial complexes, public places like supermarkets, entertainment centers, etc. Another form of temporary CAN can exist during some special events such as rallies, music festivals. The elementary Campus Area Network can also arise spontaneously, due to the distance of spread the radio signals from the access points that are not limited by buildings walls. It is also sensible to have additional access points for the larger and more complex CANs, located at specially places chosen for serving clients. Design easy diagrams and schemes for the Campus Area Networks with Computer Network Diagrams solution for ConceptDraw DIAGRAM.
