What are the two aspects of cloud security?

Cloud security includes data security and system security, which are described as follows:

1. Data security: Cloud security includes the security of data stored in the cloud. This includes protecting the confidentiality, integrity and availability of data. Cloud security measures can ensure that data is not accessed, tampered with or lost by unauthorized personnel during transmission and storage. Encryption technology, authentication, access control, data backup and disaster recovery are all common cloud security measures.

2. System security: Cloud security also includes protecting the security of cloud computing systems and infrastructure. This includes protecting system components such as cloud servers, network devices and operating systems from malicious attacks and unauthorized access. Cloud security measures can include strict access control, network firewall, intrusion detection and defense system, security audit and other technologies and strategies.

Basic knowledge of computer

1. Computer hardware: A computer consists of multiple hardware, including central processing unit (CPU), memory, hard disk, display, keyboard, mouse, etc. These hardware devices work together to complete various calculation and processing tasks.

2. Computer software: Computer software refers to various programs and applications running on the computer. Software is divided into system software and application software. System software includes operating system and various tools, and application software includes office software, entertainment software and graphic design software.

3. Operating system: The operating system of a computer is the basic software for managing and controlling computer hardware and software resources. Common operating systems are Windows, macOS, Linux, etc. Operating system is responsible for the allocation of computer resources, process management, file system management and other functions.

4. Network and Internet: Network refers to connecting multiple computers together to realize information transmission and resource sharing through data communication. Internet is a global computer network, which connects computers and network devices all over the world, making the transmission of information and resources faster. It is very important to understand the basic principles and communication protocols of the network and the Internet for using computers.
