Network Security Model

The network security involves all tools, devices, strategies and activities which enterprises and organizations undertake to protect their networks, data and operations. An effective network security strategy must include the most effective set of tools for identification and reflection various threats and attacks. Creation of well thought-out network security model will effectively help you in realization your network's security. The network security model (NSM) is a scheme that reflects the general plan and the policy of ensuring the network security, and usually includes all or some of the following seven layers in different modifications according to the specific company's needs:

  • Physical layer — involves organization of physical security against the access to the data on computer devices, this can be access control devices, cameras, alarm.
  • VLAN layer — involves creation of Virtual Local Area Networks (VLANs) which join together common hosts for security purposes.
  • ACL layer — supposes creation and maintenance of Access Control Lists (ACLs) which allow or deny the access between hosts on different networks.
  • Software layer — helps to protect the user layer and ensures the software's actuality.
  • User layer — involves the user’s training of security on the network.
  • Administrative layer — supposes the training of administrative users.
  • IT department layer — this layer is the most important for network security, it contains all network security professionals and support specialists, network technicians and architects, which organize and maintain the work of the network and hosts.

Pay please your attention for the powerful ConceptDraw DIAGRAM diagramming and vector drawing software extended with Network Security Diagrams Solution from the Computer and Networks Area of ConceptDraw Solution Park which lets fast and easy design all variety of network security models: Open network security model, Closed network security model, Restrictive network access model.

Network Security Model

Example 1. Network Security Model

To design the Network Security Model, we recommend to use already ready-to-use 460 predesigned colorful vector objects offered by 4 libraries of the Network Security Diagrams Solution:

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

Simply drag desired objects from the libraries to your document, arrange them, depict relationships between devices with help of connectors from the Cybersecurity Connectors library, type the text and make your diagram more attractive with help of bright colors applied for objects, connectors and background.

Network Architecture →

The efficiency of any corporate network depends on many factors such as equipment, architecture etc. Moreover, every administer knows that network architecture is a cornerstone for any system. Also, it's easy to make a draft of a network structure using an appropriate diagramming tool. Designing network architecture diagrams refers to the network structure, including hardware, software, connectivity, protocols of communication and type of transmission: wired or wireless. A high performance, highly reliable, and secure network architecture is critical for the successful deployment and operation of modern communication network. This diagram represents in detail the sample of the network architecture of the three-divisional office. It is designed using vector libraries supplied with ConceptDraw Computer and Networks solution.Network Architecture

Flow Chart Symbols →

If you need to describe some process, diagramming is a perfect tool for almost any imaginable purpose. The set of the most commonly used flow charts symbols is quite wide and includes symbols for operations, processes, data inputs and outputs. You can see the full list of all the symbols used for flowcharting in Flowcharts solution from Diagrams area in ConceptDraw Solution Park. A flow chart is often used for visual representation of a sequential process flow. The flowchart approach to any process is to divide it into some sequential actions. What makes a flow chart so popular and clear to make out is the set of standard flowchart symbols that has the same reading independently from processes described with their applying. The current drawing represents the vector library containing the pack of standard flowchart symbols. This library is supplied with ConceptDraw Flowcharts solution.Flow Chart Symbols *

Cloud Computing →

The Cloud Computing is the use of the software and hardware that includes the great number of computers connected over the communication network such as the Internet. The Cloud name comes from the usage the cloud symbol on the system diagrams as the abstraction for the complex network infrastructure. This term is used as a marketing metaphor for the Internet. This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the Cloud Computing.Cloud Computing *

Local area network (LAN). Computer and Network Examples →

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.Local area network (LAN) diagram
