Using an enterprise policy helps ensure the security of data in the network. It is best to have granular policies for sensitive data to ensure that breaches can be quickly addressed. Zero-trust security measures also reduce risk, prevent lateral movement of malware, and verify regulatory compliance. When network policies are defined carefully, they can be implemented to support a company’s business needs and help it maintain compliance with regulations. Think of policies as objectives and goals to help ensure that data is protected against cyber threats.
In general, computers connected to a network can be categorized as workstations or servers. Servers are usually not used directly by humans. They are typically devoted to providing services that are required for the operation of the network. Some examples of services provided by a server include printing, faxing, software hosting, file sharing, messaging, and access control. A network can be a very useful tool for companies to manage information and collaborate on projects.
A network contains nodes, which are physical connection points that can exchange information. Each of these devices is assigned an IP address to identify itself and communicate. Routers are used to determine the most effective route to reach the other network nodes. Switches connect the devices and manage node-to-node communication. The purpose of each device is to share resources. In order to do this, they use protocols to send and receive data. Generally, a network has several layers.
