What is the impact of the digital economy on security management?

Security is the cornerstone of the industrial Internet

In the era of digital economy, digitization accelerates the transformation and upgrading of traditional industries: On the one hand, industrial digitization accelerates the digital economy to enter an advanced stage. A large number of devices are connected to the network, and production The improvement of efficiency relies on in-depth data mining and the integration of the entire process. On the other hand, the security protection capabilities of traditional industries are uneven. Massive devices are connected to the network. Network security and data security are involved in the whole process application scenarios. Therefore, network attacks, ransomware viruses, and DDOS attacks are gradually increasing, and the attack surface is gradually expanding. . Taking intelligent connected cars as an example, intelligence, networking, sharing, and electrification have become the main development trends of the industry, but they are accompanied by a large number of security loopholes and remote control risks. Attackers use the vehicle's own security system vulnerabilities to attack the vehicle's software and hardware, steal and send information, and even remotely control the vehicle. Once a safety incident occurs, it will pose a significant risk to consumers' personal safety.

Xinhua News Agency, Wuhan, February 12 Japan News (Reporter Fang Zhengjun) The Hubei Provincial Public Security Department announced on the 12th that according to unified deployment, the Hubei Internet Supervision, with the cooperation of the public security agencies in Zhejiang, Shandong, Guangxi, Tianjin, Guangdong, Sichuan, Jiangxi, Yunnan, Xinjiang, Henan and other places, launched the The case of creating and spreading the "Panda Burning Incense" virus was solved, and eight suspects including Li Jun (male, 25 years old, from Xinzhou District, Wuhan) and Lei Lei (male, 25 years old, from Xinzhou District, Wuhan) were arrested.

This is the first major case of computer virus production cracked in my country.

According to reports, at the end of 2006, there was a large-scale outbreak of the "Panda Burning Incense" virus and its variants on the Internet in my country. The virus spread through a variety of ways and changed all infected program files into pandas holding three sticks. It has a fragrant appearance, and at the same time, the virus also has the function of stealing users' game accounts and QQ accounts.

The virus spreads quickly and has a wide range of harm. As of the incident, millions of individual users, Internet cafes and corporate LAN users have been infected and damaged, which has attracted great attention from all walks of life. The "Rising 2006 Security Report" ranked it first among the top ten viruses, and it became the "King of Poisons" in the top ten viruses in the "2006 Computer Virus Epidemic and Internet Security Report in Mainland China".

In mid-January this year, the Hubei Provincial Internet Supervision Department launched an investigation into the creator of the "Panda Burning Incense" virus in accordance with the deployment of the Information Network Security Supervision Bureau of the Ministry of Public Security. After investigation, the creator of the Panda Burning Incense virus was Li Jun from Wuhan City, Hubei Province. According to Li Jun, he wrote the "Panda Burning Incense" virus on October 16, 2006 and spread it widely on the Internet. He also sold it himself and created it. Others sold the virus to more than 120 people on the Internet, making an illegal profit of more than 100,000 yuan.

Further spread by virus buyers, various variants of the virus spread widely on the Internet, causing serious damage to the computer security of Internet users. Li Jun also wrote the "Wuhan Boy" virus in 2003, the "Wuhan Boy 2005" virus and the "QQ Tail" virus in 2005. In addition, there are several other important suspects in this case: Lei Lei (male, 25 years old, from Xinzhou District, Wuhan), Wang Lei (male, 22 years old, from Weihai, Shandong), Ye Peixin (male, 21 years old, from Wenzhou, Zhejiang), Zhang Shun (male, 23 years old, from Lishui, Zhejiang) and Wang Zhe (male, 24 years old, from Xiantao, Hubei) built a "botnet" by rewriting and spreading viruses such as "Panda Burning Incense" and stole various games and QQ accounts. Making profits illegally.

Currently, 8 suspects including Li Jun and Lei Lei have been detained.

Laptop zombie virus?

Botnet virus, a botnet virus, controls the compromised computer by communicating with the irc server.

A botnet (English name is botnet) is a group of computers on the Internet that are centrally controlled by hackers. They are often used by hackers to launch large-scale network attacks, such as distributed denial-of-service attacks (DDOS), massive spam, etc. At the same time, hackers control The information stored in these computers can also be "accessed" by hackers at will. Therefore, whether it is the protection of network security operations or user data security, botnets are extremely threatening risks.

What does degraded Internet performance mean?

Performance degradation mainly refers to:

1. Network equipment (information sockets, crystal heads, network cables, interfaces, etc.) is aging.

2. There are more and more high-traffic applications, which occupy a large amount of bandwidth, causing the network to slow down.

3. Virus attacks in the intranet, such as arp viruses, ddos ??viruses, and syn attacks, will cause network congestion on computers in the intranet and reduce the performance of routers and switches.

If it is not a physical fault, it is recommended to upgrade the network to an immune network, with refined bandwidth management and powerful immune device, to solve network problems from the bottom layer of the protocol, stabilize the enterprise network, and improve network quality.

What is the difference between American cloud hosting and American virtual hosting?

1. Security and Reliability

Virtual hosts are relatively poor in security and reliability, and there is also the possibility of some downtime, and in terms of defense against viruses, Trojans, and DDoS It is relatively poor. Many virtual hosts do not have backup machines and data backup services, and data usually needs to be backed up manually.

Cloud hosts are relatively much more secure. They have built-in ARP protection, which effectively improves DDOS attack prevention capabilities. Moreover, website data in cloud hosts are backed up in multiple servers at the same time, even if one of the servers is Failure will not result in loss of website data.

2. Host performance and guarantee

Many resources used by the virtual host are shared. Due to the limitations of the host environment, the performance of the virtual host cannot be guaranteed. It's relatively poor.

Cloud hosts are actually not much different from physical servers, so the security of cloud hosts is very high.

3. The scalability space of the host

The scalability of the virtual host is relatively poor. If the space traffic of the selected hosting plan is insufficient, it is basically difficult to expand, and it is usually difficult to expand. You need to reselect a hosting plan.

The cloud host is also very scalable. The webmaster can expand according to the needs of the website without having to pay for the original rented host resources.

4. Management operability

Virtual host management is more convenient. You can usually install a control panel. For example, the cpanel control panel has a graphical interface with clear functions and simple operation.

The cloud host has built-in KVM, and customers can centrally and uniformly manage cloud hosts distributed in various places through the self-service system; they have full root or super administrator operating system permissions.
