The scope of information security includes a variety of aspects such as computer network security, data security, personal privacy protection, etc., which are described in detail as follows:

A. Computer Network Security:

Computer network security is an important part of information security. It covers measures to protect computer networks from threats such as unauthorized access, malware, network attacks, and data leakage. This includes technical means such as network firewalls, intrusion detection and defense, network encryption, and secure configuration and management of network devices and systems.

Two, data security:

Data security is to protect data from illegal access, tampering, leakage and loss of security measures. This includes encryption, backup and storage management of data to ensure data integrity, availability and confidentiality. Also data security involves protection during data transmission, such as the use of secure protocols and encryption to transmit data.

Third, personal privacy protection:

Personal privacy protection is an important aspect of information security, which involves the protection of personal identity, financial information, health records and other sensitive personal information. In the digital age, the risk of privacy leakage is increasing, so personal privacy protection needs to include legally compliant data collection and use, as well as confidentiality measures for sensitive personal information.

IV. Authentication:

Authentication is the process of confirming a user's identity and ensuring that only legally authorized users have access to systems or resources. Authentication techniques include passwords, biometrics, smart cards, and many other methods. Authentication also includes multi-factor authentication, such as combining passwords and biometrics to improve the security of authentication.

V. Physical Security:

Physical security is the protection of information systems and equipment from physical threats. This includes measures such as access control, video surveillance, fire and waterproofing of critical facilities such as server rooms, server rooms, and network equipment. Physical security also involves the secure disposal of equipment, such as the secure destruction of data from storage media and devices.

VI. Security Awareness:

Education and TrainingSecurity Awareness Education and Training is an important part of information security. It helps employees identify and prevent security threats by improving their security awareness and knowledge. Security awareness education and training can include regular security training courses, publicity and promotion of security strategies, and activities such as simulation exercises and case studies.
