4.0 Network+ Certification Cram Notes : Network Security
Network security is the process of protecting a computer network from unauthorized access, theft, and damage by implementing various technologies, policies, and procedures. It involves protecting all components of the network, including servers, switches, routers, firewalls, end-user devices, and the data stored and transmitted over the network. The goal of network security is to ensure the confidentiality, integrity, and availability of data and network resources, while preventing unauthorized access, modification, or destruction of network components. This can be achieved through a combination of hardware, software, and processes that are designed to detect, prevent, and respond to security threats and vulnerabilities.
