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.
This computer security diagram example was designed on the base of the Wikimedia Commons file: Firewall.png.

"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.

Use ConceptDraw DIAGRAM diagramming and vector drawing software enhanced with Computer and networks solution to draw different types of network diagrams: physical layout and topology, LAN and WAN, Cisco, Apple, Wi-Fi wireless and Ethernet wired networks, etc.
Special libraries of highly detailed, accurate shapes and computer graphics, servers, hubs, switches, printers, mainframes, face plates, routers etc.

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.

Data Flow Diagram Software

When studying a business process or system that involves the transfer of data, it is common to use a data flow diagram (DFD) to visualize how that data is processed. While initially used exclusively in regards to the flow of data through a computer system, DFDs are now employed as a business modelling tool, describing business events and interactions, or physical systems involving data storage and transfer.
ConceptDraw DIAGRAM is a powerful Data Flow Diagram Software thanks to the Data Flow Diagrams solution from the Software Development area of ConceptDraw Solution Park.
You can use the predesigned DFD vector objects that are grouped in 3 libraries of Data Flow Diagrams solution: Data Flow Diagrams Library; Gane-Sarson Notation Library; Yourdon and Coad Notation Library.
