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.

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.UML Notation *

ERD Symbols and Meanings →

A database is a data collection, structured into some conceptual model. Two most common approaches of developing data models are UML diagrams and ER-model diagrams. There are several notations of entity-relationship diagram symbols and their meaning is slightly different. Crow’s Foot notation is quite descriptive and easy to understand, meanwhile, the Chen notation is great for conceptual modeling. An entity relationship diagrams look very simple to a flowcharts. The main difference is the symbols provided by specific ERD notations. There are several models applied in entity-relationship diagrams: conceptual, logical and physical. Creating an entity relationship diagram requires using a specific notation. There are five main components of common ERD notations: Entities, Actions, Attributes, Cardinality and Connections. The two of notations most widely used for creating ERD are Chen notation and Crow foot notation. By the way, the Crow foot notation originates from the Chen notation - it is an adapted version of the Chen notation.ERD Symbols and Meanings

Pyramid Diagram and Pyramid Chart →

Any hierarchical structure of any company can be represented as a triangle or a pyramid. You can create a pyramid diagram and pyramid chart of any complexity using special libraries included in ConceptDraw DIAGRAM. Actually, any knowledge or chain of facts can also be depicted as a pyramid. A wide range of graph and chart are utilized in marketing to maintain documentation and various visual issues, that deal with marketing information and data. The marketing value pyramid can be created to illustrate how the value of company, or product is based on its competitiveness. To design this diagram we used ConceptDraw DIAGRAM drawing tools in conjunction with Pyramid solution for Solution Park.Pyramid Diagram and Pyramid Chart *
