With regard to cyber security technology, a newer and more detailed technology is required

Relatively new technology. Intrusion detection is OK (IDS), here is the introduction.

There are many types of IDS, such as intrusion detection technology based on artificial immune system. You can go to Wanfangshang or other places to find some** to see, and you don't need to spend money if you use the resources of the library.

Network security refers to the ability to prevent attacks, intrusions, interference, sabotage, illegal use and accidents on the network by taking necessary measures to ensure the stable and reliable operation of the network, as well as the integrity, confidentiality and availability of network data.

Article 76 of the Cybersecurity Law provides the following terms for this Law:

1) "Network" refers to a system composed of computers or other information terminals and related equipment that collects, stores, transmits, exchanges, and processes information in accordance with certain rules and procedures.

2) "Network security" refers to the ability to prevent attacks, intrusions, interference, destruction, and illegal use of networks, as well as accidents, to keep networks in a state of stable and reliable operation, and to ensure the integrity, confidentiality, and availability of network data by taking necessary measures.

3) "Network operators" refers to network owners, managers, and network service providers.

4) "Network data" refers to all kinds of electronic data collected, stored, transmitted, processed, and generated through networks.

5) "Personal information" refers to all kinds of information recorded electronically or otherwise that can identify a natural person's personal identity, either alone or in combination with other information, including but not limited to a natural person's name, date of birth, ID number, personal biometric information, address, ** number, and so forth.

Network security technology mainly includes physical security analysis technology, network structure security analysis technology, system security analysis technology, management security analysis technology, and other security services and security mechanism strategies.

Commonly used techniques such as the following:

1. Virtual network technology. The virtual network technology is mainly based on the LAN switching technology (ATM and Ethernet switching) that has been developed in recent years. Switching technology evolves traditional broadcast-based LAN technology into a connection-oriented technology.

2. Firewall technology. Everyone is familiar with the term firewall, which can be said to be synonymous with network security. A firewall (including a security gateway) in a network is a special network interconnection device and related technology used to strengthen access control between networks, prevent external network users from entering the internal network through the external network by illegal means, access internal network resources, and protect the internal network operating environment.

The institution is a leading vocational education company in the industry, committed to the IT Internet industry, training software development engineers, system administrators, UI designers, network marketing engineers, accountants and other workplace talents, with a strong faculty, practical lecturers to teach practical experience, some lecturers have worked in IBM, Microsoft, Oracle-Sun, Huawei, AsiaInfo and other enterprises, its teaching and research team with the chaotic team is an exclusive 26 major curriculum system, to help students learn systematically, At the same time, it also cooperates with major universities to help students develop their career directions.

Network security mainly includes key technologies such as authentication and authorization, encryption, security protocols, firewalls, intrusion detection, security management, and data backup and recovery.

1. Authentication and authorization technology: Authentication and authorization is the basic technology of network security, and it is a method to determine the identity of network users and authorize access to network resources.

2. Encryption technology: In network transmission, the data is converted into ciphertext through encryption technology, so as to prevent illegal users from stealing data and attacks.

3. Security protocol: The network protocol is the basic foundation of communication between devices, so the security protocol is a necessary technology to ensure network security.

4. Firewall: Firewall can monitor and filter network traffic, so as to ensure the security and legitimacy of the network system.

5. Intrusion detection: This technology can detect intrusion behaviors in the network, detect and block intrusions in time, and protect the security of network systems.

6. Security management: including the formulation of security policies, the handling of security events, the location and repair of security vulnerabilities, network monitoring, etc., so that network security management becomes more standardized and efficient.

7. Data backup and recovery: In the network system, data loss or data damage may occur at any time, in which case data backup and recovery is very necessary.

Cyber security issues to pay attention to

1. Be vigilant against social networks: Be vigilant against immoral and illegal behaviors in social networks, and report and prevent them in a timely manner.

2. Timely update of security software: Timely update of security software can protect the computer from new viruses, malware and spyware.

3. Avoid public WiFi: Try to avoid using public WiFi connections for network activities, as these connections may have security risks and data traffic can be easily stolen.

4. Strengthen password management: Password is the key to the protection of important personal and enterprise information, and it is necessary to formulate a secure password strategy to avoid the risk of leakage. For example, generate complex passwords randomly and change them regularly, don't use the same password or shout it out to multiple accounts.

Network information securityThe technical characteristics are integrity, confidentiality, availability, non-repudiation, and controllability.

Cyber security is a science that involves computers.

Network Technology, Communication Technology, Cryptography Technology, Information Security Technology, Lu Tong, Applied Mathematics.

Number Theory, Information Theory.

It is a comprehensive discipline of various disciplines.

It mainly refers to the protection of the hardware, software and data in the network system from accidental or malicious reasons, the continuous, reliable and normal operation of the system, and the uninterrupted network service. The continuous integration and development of information technology has led to the development of more security elements in information security, such as authenticity, non-repudiation and practicability.

The development of information technology and the acceleration of the process of digital file notification and calling in the promotion of the first and enterprise information system at the same time, but also brought greater security risks and risks, in order to reduce security risks, improve the security level, solve security problems, a new and huge industry was born - information security industry.

Today's cybersecurity has several main features:1Complexity:

With the development of technology and the popularity of the internet, cybersecurity threats have become more sophisticated. Hackers and malware developers are constantly exploring new attack vectors using advanced technologies and tactics to make cybersecurity more challenging. 2.

Global: Cybersecurity issues transcend national borders and become a global challenge. Cyberattacks can be launched from anywhere, and the Internet has made it possible for information to spread around the world in an instant.

As a result, cybersecurity requires cooperation and coordination on a global scale to address threats. 3.Diversity:

Cybersecurity threats come in many forms, including malware, phishing, data breaches, and more. At the same time, various fields and industries are facing different security challenges, such as financial institutions, Sui Roll ** institutions, enterprises, etc. Therefore, cyber security requires diversified defense measures for different scenarios and threats.

4.User Participation Families with Caution: Users play a key role in network security.

They need to be more aware of security and take the right security measures, such as using strong passwords, updating software regularly, and being wary of phishing emails. At the same time, users also need to actively participate in the discussion and decision-making process on cybersecurity compliance and privacy protection.
