Network Acess Control protocols

Network access control or NAC is one aspect of network security. NAC defines the security protocols that are used between various applications and components in order to manage access to network resources. NAC refers to a set of interconnected protocols that relate to networking also there are software that help with this, which you can get from professionals as Fortinet and others. A network access control (NAC) policy applies to the access a user has to the network. NAC policies can contain any combination of network access control methods and these methods can be either static or dynamic. If a user is denied access to a network resource, it is not possible for the user to be granted access to the resource again by using any other network access control method. The same applies to other users. NAC Policies can take any form of form which relate to network resources, and they can be applied to common network resources such as TCP/IP or LANs. The user interface for NAC applications are usually embedded in network programs or can be implemented independently. The whole architecture is called network access control and it is managed in multiple stages in order to ensure the security and operation of the network. The most important factor in NAC is the way in which the processes interact. There are four main types of interaction: Static, Global, RouteBased and User-based. A single service can have different policies, for example one may allow only static or global access to the service. In the real world, it is impossible to make a firm statements about this, as certain network applications have different needs, and hence it depends on the needs of the particular network application. The dynamic nature of NAC is the next logical step in the user-based aspect of NAC. The user is able to assign static and dynamic policies to a particular application at runtime. User-based NAC is in essence a user intervention, that is, it is initiated at runtime by the user. In addition to NAC, there are other security policies that take the form of policy templates. These can be a simple pass/fail based policy or a complex security policy that considers how sensitive data should be stored.

What are service names? What are computer names?

In the context of security, a service name or computer name is a unique name used to identify a service. Most commonly, service names consist of a computer name followed by a set of digits. The first digit describes the type of service. For example, TCP is a service type which uses a computer name as the first digit. The second digit is used to identify the implementation. A program using this service type would generally use TCP port 5555. The third digit is used to identify the address where a service is run. This number is typically generated on a per-process basis. For example, the third digit for the kernel machine name (p) in Linux is 3. Any other value would be invalid and not recognized as a service type. Other service names include file and database services, system services, and service control services.

You are probably also wondering about what computers are called and what websites are called? Why do we have names? The reason for us having a list of names is to avoid conflicts. For example, if you were going to register a computer, you would register it under a name such as “UNIX”.
