Network Security Devices
Assurance of network security is one of the most important moments for safe and correct working of the computer systems and networks. The network security includes assurance of the limited access to sensitive information, the protection from unauthorized access, risks and potential security threats, and enhancement of network performance. It is necessary to protect the network at all of its entry points, the most important factors in network security are encryption, reliable passwords, the use of antivirus software and modern advanced network security devices.
There are few types of network security devices:
- active devices - firewalls, antivirus scanning devices, content filtering devices, which block the surplus traffic;
- passive devices, such as intrusion detection appliances, which identify and report on unwanted traffic;
- preventative devices - penetration testing devices and vulnerability assessment appliances, which scan the networks and identify potential security problems;
- Unified Threat Management (UTM) devices, such as firewalls, content filtering, web caching, which serve as all-in-one security devices.
The most popular network security devices are firewalls - network security systems which establish a barrier between an internal network and the Internet, effectively manage and regulate the network traffic based on some protocols. Firewall can be software or hardware appliance, or include together hardware and software devices, most computers use software-based firewalls to secure their data from Internet threats, many routers also contain the firewall components.
Such network security devices as routers, crypto-capable routers, virtual private network gateways, secure modems and intrusion detection systems are also very popular. Intrusion detection systems are devices that monitor malicious activities in a network, log information about such activities and take active steps to stop them, and then report them.
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.

TEN RELATED HOW TO's:
A network diagram represents the set of computers and network devices and the connections among them. This scheme can be developed for any institution or establishment. To illustrate this concept let’s take for example, a hotel network topology diagram or a school network diagram. These diagrams depict access points, servers, workstations, firewalls and another equipment needed to provide a network.
On this masterpiece drawing one will see a simple scheme a of connecting computers together. Such form of connecting can be applied for a hotel, guest house, bungalow, hut or something else. This diagram shows the images of the real LAN components. So, it represents a physical category of a network construction. It looks similar to a star - so this network configuration is named a star topology. The typical feature of this construction is a center point - usually it is hub, or router. The rays of this star means network connections. Computers, peripherals and other network details are placed on the ends of the star rays.

While creating flowcharts and process flow diagrams, you should use special objects to define different statements, so anyone aware of flowcharts can get your scheme right. There is a short and an extended list of basic flowchart symbols and their meaning. Basic flowchart symbols include terminator objects, rectangles for describing steps of a process, diamonds representing appearing conditions and questions and parallelograms to show incoming data.
This diagram gives a general review of the standard symbols that are used when creating flowcharts and process flow diagrams. The practice of using a set of standard flowchart symbols was admitted in order to make flowcharts and other process flow diagrams created by any person properly understandable by other people. The flowchart symbols depict different kinds of actions and phases in a process. The sequence of the actions, and the relationships between them are shown by special lines and arrows. There are a large number of flowchart symbols. Which of them can be used in the particular diagram depends on its type. For instance, some symbols used in data flow diagrams usually are not used in the process flowcharts. Business process system use exactly these flowchart symbols.

Local area network connects computers and other network appliances within an area, such as office building or a campus. It can be difficult to provide such network without a predesigned plan. For these purposes you can use network diagram software, which helps you to create LAN network diagrams and office network diagrams quickly and effortless. This will speed up your work and you can save the diagram for the future network improvements.
The following diagram illustrates a network topology of the small office. LAN configuration has a star topology. The local network joins 8 computers among which are several desktop PCs, laptop, two iMacs and iBook. The end-point devices are divided into three groups. Each group is connected to its hub. There is a network printer and a modem, which are interconnected with other devices through a network server. Each computer on the LAN can access the server through a corresponding hub.

Computer networks nowadays are spread all across the world. The large number of parameters, such as geographic scale or communication protocols, can divide networks. One of the most common types of networks is called local area network (LAN). It convenient to represent network examples by means of diagrams.
This local area network (LAN) diagram provides an easy way to see the way the devices in a local network are interacted. The diagram uses a library containing specific symbols to represent network equipment , media and the end-user devices such as computers (PC, mac, laptop) , network printer, hubs, server and finally a modem. There are two types of network topologies: physical and logical. The current diagram represents precisely a physical type of LAN topology because it refers to the physical layout of a local network equipment.

In general, you can use any icons to represent network equipment on a diagram. However, there are some icons, for instance, Cisco icons, shapes, stencils and symbols, that are recognizable worldwide. Using those icons you can create Cisco network topology diagrams in minutes and share them anywhere.
The icons depicting Cisco network equipment are recognized and generally applied as standard images for designing network diagrams. They are free to used , but can not be reworked. Cisco network diagrams are created to depict how signals processed on the network equipment and end-user computers and how data transfer through LAN or WLAN between nodes. The vector graphic library of ConceptDraw CISCO Network Diagrams solution includes about 90 icons of Cisco network equipment for designing computer network diagrams with ConceptDraw DIAGRAM.

If you want to find a way to understand complex things in minutes, you should try to visualize data. One of the most useful tool for this is creating a flowchart, which is a diagram representing stages of some process in sequential order. There are so many possible uses of flowcharts and you can find tons of flow charts examples and predesigned templates on the Internet. Warehouse flowchart is often used for describing workflow and business process mapping. Using your imagination, you can simplify your job or daily routine with flowcharts.
Warehouse flowcharts are used to document product and information flow between sources of supply and consumers. The flowchart provides the staged guidance on how to manage each aspect of warehousing and describes such aspects as receiving of supplies; control of quality; shipment and storage and corresponding document flow. Warehouse flowchart, being actual is a good source of information. It indicates the stepwise way to complete the warehouse and inventory management process flow. Also it can be very useful for an inventory and audit procedures.

What is a computer network? This is a set of devices and systems that are connected to each other (logically or physically) and communicate with each other. This could include servers, computers, phones, routers, and so on. The size of this network can reach the size of the Internet, and can consist of only two devices connected by a cable.
This sample shows the connection scheme of the home WLAN equipment to the Internet.
