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.

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 diagrams with ConceptDraw DIAGRAM →
Of course it is possible to keep network records in text documents, but it is very difficult to use them later. A more sound way to keep such documentation is to create a network diagram that might represent either logical network structure or physical. These diagrams are easy to understand and you will thank yourself later. There is a physical network diagram. It is a tool to represent, maintain and analysis of network equipment and interconnections. Network diagram depicts the actual network information in the attractive clear graphic form. One can learn here the LAN cable length, telecommunication type and carrying capacity. The diagram depicts servers, IP address and domain name as well. Also it shows location of hubs, switches, modems, routers, and other network equipment. The sets of special symbols and images delivered with ConceptDraw Network Diagrams solution are used to show network components. Symbols have a standard view. Therefore, various specialists can read the network diagram without any discrepancies.

UML Notation →
There are many ways to track the system in a critical situation. To model a system behavior, uml notation is widely used. Usually, an UML diagram consists of elements such as actor and a case. This diagram represents the structure of UML notations. Unified Modeling Language (UML) is used in software engineering to depict graphically the software modeling process. UM Language uses graphic notations for developing models of object-oriented systems. These notations displays requirements, sub-systems, logical and physical elements, etc. We created this diagram using ConceptDraw DIAGRAM reinforced with Rapid UML solution. It can be helpful for students on software engineering, when learning UML.
