1. Safety and security are two concepts that relate to the protection of computers and their data. Safety generally refers to the condition of being protected from danger or risk, while security has a broader connotation, implying a higher level of protection, including safety and confidentiality.
2. In terms of computer terminology, security is often associated with external threats and defense mechanisms. It encompasses measures and practices designed to ensure the confidentiality, integrity, and availability of data within a networked environment.
3. Computer network security is a subset of security that focuses on protecting data transmissions over networks. This includes the use of various management controls, policies, and technologies to prevent unauthorized access, modification, or destruction of information.
4. There are two main aspects to computer network security: physical security and logical security. Physical security ensures that the hardware and infrastructure of a system are protected from damage, loss, or theft. Logical security, on the other hand, deals with the protection of information from unauthorized access, ensuring its integrity, confidentiality, and availability.
