How to Prevent Cyber Security About 50 words

Settings, close redundant services and redundant applications, update system patches, and don't install too much software.

Develop good online habits.

Cybersecurity can be roughly divided into three parts:Device system security, data content security, and operation behavior security.

1. Equipment safety

It is a device for data storage, iteration and so on in the physical sense, or servers, hard disks, etc., which is the material basis of network security, and it is also the first issue to be considered in network security. If your device is damaged, then whatever you do will be useless.

2. Data content security

Generally speaking, when we talk about content security, we mean that the data content complies with the laws and regulations of the country. However, in addition to this, there are actually two encryption methods for the encryption and transmission of the content itself, and there are currently two main encryption methods we use: symmetric encryption (private key encryption) and asymmetric encryption (public key encryption).

3. Safe operation

In fact, the behavior of operations in the network can also threaten the security of the network.

According to statistics, more than 80% of security threats to enterprises are due to the lack of effective management methods and strict authority management systems, resulting in internal personnel actively or passively leaking a large amount of data and information through mobile devices or networks when using networks and devices.

In the social engineering type of threat, criminals gain trust by pretending to be internal employees through corporate information they hold, and then further gain access to internal secrets.

1. Install anti-virus software and firewalls and update them in time.

2. Develop good Internet habits and don't click on some bad ** and emails.

3. Regular anti-virus and timely patching of the system.

4. Learn network security knowledge and stay away from hacker tools.

Network security means that the hardware, software and data in the network system are protected from damage, alteration and leakage due to accidental or malicious reasons, and the system runs continuously, reliably and normally, and the network service is not interrupted. It has the characteristics of confidentiality, integrity, availability, controllability, and auditability.

Information security does not happen three times:1. Ensure that there is no large-scale information system failure and shutdown accident.

2. Ensure that no malignant information leakage accidents occur.

3. Ensure that there is no malicious tampering accident on the information extranet.

Information security threats in the network environment are:

1. Impersonation: refers to the behavior of illegal users invading the system and impersonating legitimate users by entering information and other information to steal information;

2. Identity theft: refers to the interception of legitimate users by other illegal users in the normal process of communication;

3. Data theft: refers to the interception of data from communication networks by illegal users;

4. Denial: refers to the fact that the communicating party does not admit that it participated in a certain activity after participating in it;

5. Refusal of service: refers to the refusal or delay of service by a legitimate user when making a legitimate application;

6. Wrong routing;

7. Unauthorized access.

Measures to improve information security precautionsStrengthen the construction of network security infrastructure, promote the construction of network security situational awareness and emergency response platforms, improve network security situational awareness, and build an emergency command system with unified command, sensitive response, coordination and orderly, and efficient operation. Strengthen the construction of a team of network security experts and technical support teams that combine specialization and socialization.

Implement national science and technology and industrial policies, study and formulate policies and measures to adapt to the new characteristics of the development of the information technology industry under the new situation, guide the research and development of core network security technologies and the transformation of achievements of enterprises such as Antiy, Anxin and Cheng, support scientific research institutions and enterprises to actively undertake the research and development of major national information technology core technologies, and promote the rapid development of the network information technology industry with "big intelligent cloud" as the core.
