Network and Application Security Engineer certificate: This certificate trains network and application security engineers in basic knowledge and skills, including vulnerability scanning techniques, network security policies, application security vulnerability analysis and resolution, etc. These certificates are just the tip of the iceberg in the field of network security. If you are interested in network security, you can study and take more certificates to expand your skills and knowledge.

The management of the network in terms of security and efficiency can vary. It depends on factors like the type of network, the implemented security measures, and the level of optimization for performance.

There were many books related to computer network security and hacker knowledge. The following were some of the more classic ones: Computer Network Security: From Entry to Practice ( Kerrisk): This book provides a large number of computer network security practice cases suitable for beginners to read. 2 Hacker Attack and Defense Techniques: Network Combat ( ): This book is a comprehensive hacker attack and defense techniques, including all aspects of computer network security. 3. Computer Network Security: Operating System and Hacker Attack and Defense Techniques ( B Brown): This book introduced the basic knowledge of computer network security and hacker attack techniques, focusing on the security issues of the Windows operating system. 4. The authoritative guide to Web application security ( Heinemeier Hansson): This book is a very comprehensive guide to Web application security, covering all aspects of Web application security, including SQL injection, cross-site scripting attacks, XSS, and so on. 5 "Hacker Attack and Defense Techniques: Network programming"( ): This book introduced the network programming aspects of hacker attack and defense techniques, including the CPU/IP protocol, socket programming, etc. Other than that, there were many other classic books that could be chosen according to one's interests and needs.

If you like urban supernatural novels, I recommend Supercomputer Doppelgangers. The protagonist of this novel, Ye Cheng, has obtained a supercomputer clone. It involves knowledge of applications, software, hardware, systems, and network security. Perhaps it can satisfy your interest in computer network security! I hope you like my recommendation. Muah ~

Network security refers to the use of technical means to protect computer networks and systems from various attacks, threats, and destruction to ensure their normal operation and data security. The importance of network security is self-evident. Every field of modern society relies on the Internet and computer network. Network security has become one of the important factors for national security and economic development. The defense measures of network security include encryption technology, access control, network security tools, firewall, intrusion detection and prevention system, etc. These defensive measures can help protect the network and systems from various attacks such as viruses, hacker attacks, malicious software, fishing, and so on. At the same time, network security also involved the protection of users 'personal privacy, such as data encryption, privacy protection, and so on. In order to ensure network security, we need to take a series of preventive measures such as regularly updating the operating system and software, carefully opening emails and documents from unknown sources, using strong passwords and multi-factor authentication. At the same time, it was also necessary to strengthen the training and awareness of network security to improve the user's security awareness and defense ability.

One of the top stories could be the increasing threats of ransomware attacks. Hackers target various organizations, from small businesses to large corporations, encrypting their data and demanding ransom for its release.

Network security is a broad and important topic involving computers, networks, encryption, security protocol, vulnerability scanning and many other fields. The following are some topics that might be suitable for cybersecurity: 1. Cyber security strategy: Exploring how to develop and implement effective cybersecurity strategies, including risk assessment, security vulnerability management, access control, threat detection, and response. 2. Basic knowledge of encryption: Study the basic principles and techniques of encryption, including digital signatures, hashing functions, encryption algorithms, authentication agreements, etc. 3. Cyber attack and defense: Study the types and methods of network attacks and how to prevent these attacks through defensive measures. This included vulnerability scanning, network security tools, firewall, intrusion detection system, and so on. 4. Cyber security laws and regulations: Understand the relevant cybersecurity laws and regulations, including the CEH Act of the European Union, the cybersecurity laws of the United States, and national cybersecurity regulations. 5. Cyber security education and training: Exploring how to provide effective cybersecurity education and training, including introductory courses, security agreements, the use of security tools, security awareness, and so on. 6. Cloud security: Research on security threats and defense measures in the cloud computing environment, including data leakage, identity theft, network attacks, etc. 7. Blockchain Security: Exploring the security and defense measures of the Blockchain, including the Decentralized Network, smart contracts, consensus algorithms, etc. 8. Network security assessment: Research on how to assess network security systems, including vulnerability scanning, security audit, threat detection, etc. These topics are all hot topics in the field of network security. They can inspire you to study and understand the field. Of course, the specific topic will depend on your interests and professional background.

The network security algorithm was as follows: Suppose there is a network where every node can send messages to other nodes, but the message transmission between each node is irreversible. In other words, if a node receives an irreversible message, it cannot send it to other nodes. Assuming that node A wants to send a message to node B, node B wants to send the message to node C, but node B receives an irreversible message, then node C cannot receive the message. How do I design an algorithm to ensure the integrity of the message delivery? Answer: An algorithm called the " message integrity algorithm " was designed to ensure the integrity of message delivery. The steps of the message integrity algorithm were as follows: 1. Confirm message type: Confirm the message type such as message ID, message content, etc. 2. Confirm the message delivery rules: Confirm the message delivery rules between each node, such as the message type and delivery direction. 3. Design a verification mechanism: Design a verification mechanism to ensure the accuracy of the message passing rules. For example, the number of irreversible messages received by each node is calculated and compared with the number of messages received by the node that sent the message. 4. Realizing the message integrity algorithm: Realizing the message integrity algorithm and using the message passing rules for verification. 5. Test: Test the algorithm to ensure that it can ensure the integrity of the message delivery. Through the above steps, a message integrity algorithm can be designed to ensure the integrity of message transmission.
