Briefly describe the main features and threats of various network security risks.

Main characteristics of various network security risks

1, the openness of the network, the technology of the network is completely open, which makes the network face attacks from many aspects. It is either an attack from physical transmission lines, an attack on network protocols, and an attack on computer software and hardware vulnerabilities.

2. The internationality of the network means that the attacks on the network come not only from users of the local network, but also from hackers from other countries on the Internet. Therefore, network security is facing the challenge of internationalization.

3. Freedom of the Internet. Most networks have no technical restrictions on users' use. Users can surf the Internet freely, publish and obtain all kinds of information.

Threats:

1, data leakage is generally considered as one of the most worrying security threats for enterprises today. The leakage of some data is just that users inadvertently put forward wrong suggestions on which applications can view and transmit their information. Accidental leakage is also the main reason for data leakage in many cases.

2. The threat of mobile network security caused by social engineering fraud is also a big point. Social engineering deception is to extract the secrets of user system from legitimate users by means of conversation, deception, impersonation or spoken language.

Phishing attacks on mobile devices are three times higher than those on the desktop, partly because people are most likely to see messages on mobile phones, especially smart phones with small screens and limited detailed information, which may also increase the success rate of fishing.

Extended data:

Guard against network security risks

1, publicize the basic knowledge of network security. For example, mobile phones and smart cameras may be remotely controlled at any time and become eavesdropping and sneak shots; Free use of all kinds of intelligent software requires opening the positioning system, which also means that your daily life is completely recorded by the network; The deleted and formatted information can be recovered, and it seems that the WeChat circle of friends with only a few close friends has almost no security.

2. Encourage netizens to develop good habits of surfing the Internet and using the Internet. For example, the work mailbox and private mail are separated; Don't click on unknown links and be highly vigilant about free WIFI; ; Cover computer cameras in daily work and so on.

3. Strengthen netizens' encryption awareness and correct encryption methods. Information encryption, like locking the door, is a skill that every netizen must master. There are three major taboos in password setting: avoid too simple password setting, avoid using the same password for all information encryption, and avoid saving different passwords in the computer. The basic password setting is numbers+letters 10 digits or more.
