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.

Example 1. Network Security Devices

The drawing tools of Network Security Diagrams Solution are very useful for network security design. This solution offers large collection of predesigned vector security clipart, icons, connectors and vector objects of network security devices developed by professional designers specially for ConceptDraw DIAGRAM users. All these 460 vector objects are grouped in 4 libraries:

• Cybersecurity Clipart
• Cybersecurity Round Icons
• Cybersecurity Shapes
• Cybersecurity Connectors

Example 2. Cybersecurity Clipart Library Design Elements

Each of these objects is ready-to-use. All that you need is simply double-click the icon at the library to add the chosen object in a moment to the middle of your document. Another way is to drag desired object from the library to the document page. Then you can arrange the objects, connect the objects in a desired way, add the text and make formatting changes.

Example 3. Network Security Diagram - Government Cloud Diagram

The samples you see on this page were created in ConceptDraw DIAGRAM using the tools of Network Security Diagrams Solution for ConceptDraw DIAGRAM software and demonstrate network security schemes with using the network security devices. An experienced user spent 10 minutes creating each of these samples.

Use the Network Security Diagrams Solution for ConceptDraw DIAGRAM to create your own Network Security Diagrams quick, easy and effective.

All source documents are vector graphic documents. They are available for reviewing, modifying, or converting to a variety of formats (PDF file, MS PowerPoint, MS Visio, and many other graphic formats) from the ConceptDraw STORE. The Network Security Diagrams Solution is available for all ConceptDraw DIAGRAM users.

Cisco Routers. Cisco icons, shapes, stencils and symbols →

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

Network Topologies →

When describing any computer network, we imagine a set of devices and nodes, arranged in some way. Talking about network structures, we should distinguish physical and logical network topologies, as physical topology is about devices location and logical topology illustrates data flow. In the same time, they do not have to match, and some devices, such as repeaters, may have a physical star layout, but a bus logical topology. There are two main types of computer network topologies: Physical topology that show the physical organization of a network - equipment and types of connections. Star network topology involves a set of devices that is connected to a single hub (router). Ring network topology means that, devices connected according this topology have two connections, connecting with nearby devices to make a loop. Bus network topology is the topology presented at the current diagram. It is similar to a ring topology. The difference is that data moves up and down a linear connection, copying itself where network equipment works as bus-stations along the way. This network topology can be used for small network, or when adding an extra device into a network.

Interior Design. Site Plan — Design Elements →

Aside from decorating inner spaces, which is a realm of interior design, the art of exterior design is about home facades, playgrounds and yards. To start a project, first of all, you need a site plan of the place, and a list of customers’ requirements. With special software you can do a plan of any place like parking, interchange or driveway easily. There is one of the three libraries supplied with ConceptDraw Site Plans solution. It is designed to draw planning areas adjacent to buildings. For example parking, exit road or house territory for rest. This kind of building plans can be used for providing parking control that helps to organize traffic near residential areas. The well considered road planning will improve safety and will help to manage the number of vehicles near buildings. The ConceptDraw library "Parking and Roads" includes vector graphic images of parking spaces, lots and strips as well as street junctions, driveways and interchanges.
