Differences and relations between information security and network security

The differences and connections between information security and network security are mainly reflected in the following aspects:

Relationship between inclusion and inclusion: information security includes network security, and information security also includes operating system security, database security, hardware equipment and facilities security, physical security, personnel security, software development, application security and so on. Network security is a subset of information security, which mainly studies computer security in network environment.

Different devices: Network security focuses on computer security in the network environment, such as how to prevent hackers from invading and how to protect network devices and servers. Information security pays more attention to the security of computer data and information, and how to protect the data stored in the computer from being leaked, tampered with or destroyed.

Emphasis is different: network security pays more attention to the network level, such as deploying firewall, intrusion detection and other hardware devices to achieve link-level security protection, while the information security level is far greater than the coverage of network security, and information security is from the perspective of data security protection.

Different solutions: Common means of network security include deployment of firewall, intrusion detection, auditing, penetration testing, risk assessment, etc. , mainly focusing on the security protection at the network level. In addition to the protection at the network level, information security also pays attention to the application level, such as data encryption, access control and security policies. It can be said that information security is closer to the actual needs and ideas of users.

Threats and risks are different: threats and risks faced by network security mainly come from network attacks, malicious codes, viruses and so on. These threats may cause damage to network devices and servers. The threats and risks faced by information security are more extensive, including information leakage, information tampering and information loss. These threats may damage personal privacy and company secrets.

Both enterprises and individuals should attach importance to information security and network security. Personal words are the most informative instant messaging tools, and a huge amount of information is generated through chat tools every day. If the information on the chat software is leaked, the consequences will be unimaginable.

Many foreign instant messaging tools, such as WhatsApp, Signal and Telegram, all adopt end-to-end encryption algorithm. This encryption technology can ensure that information is not obtained by third parties, but these softwares can't be used normally in China. If they are used in depth, they may be invited to tea, which is very risky. Domestic bats can be used to solve this problem.

This software is not only technically encrypted, but also has many functions to protect personal privacy information, such as device lock, preset secret letter and two-way cash withdrawal.

After turning on two-way recall, you can recall all chat records with one click, leaving no trace.

Generally speaking, network security and information security are interrelated and interdependent. When protecting personal privacy, it is necessary to comprehensively consider both network security and information security, and adopt a comprehensive solution to ensure the safety and reliability of the system.
