Today, I will talk to you about the current situation of sql injection attacks, which may not be well understood by many people. in order to make you understand better, the editor has summarized the following for you. I hope you can get something according to this article.

With the rapid development of network technology and information technology in the world, Web applications have the advantages of unified interface, easy to use, easy to maintain, good expansibility, high sharing and so on. Web applications have been applied to every corner of life. However, the Web application is based on the wide area network, and its security control ability is weak. And the level and experience of developers are uneven, a considerable number of programmers do not make the necessary legitimacy judgment on the input data of users or the information carried on the page when writing code. Attackers take advantage of this opportunity to submit a database query code, according to the results returned by the program, they can get some database information.

Now the general database management system has some tools and functional components, which can be directly connected to the operating system and network, which undoubtedly provides us with a lot of convenience. But when an attacker attacks a database system through SQL injection, the harm is not limited to the data stored in the database, but the attacker can also try to gain interactive access to all hosts in DBMS, so that the harm spreads from the database to the operating system and even the whole network. Therefore, I should see SQL injection attacks not only as a threat to data stored in the database, but also as a threat to the entire network.

Network attack technology

This paper briefly analyzes some loopholes existing in the application status of SQL injection attacks, and puts forward some defense countermeasures, so that web applications can improve their security and expansibility while being easy to use and easy to maintain.

The concept of network attack

The modern word of network attack refers to the attack on the hardware, software and data of the network system by making use of the loopholes and security defects of the network.

Network attack trend

1. The degree of automation and the speed of attack are improved. With the advent of distributed attack tools, attackers can manage and coordinate a large number of deployed attack tools distributed across many Internet systems. At present, distributed attack tools can launch denial of service attacks more effectively, scan potential victims and harm systems with security risks.

2. Attack tools are becoming more and more complex. Attack tools are increasingly being developed to be executed on a variety of operating system platforms. Many common attack tools use protocols such as IRC or HTTP to send data or commands from the intruder to the attacked computer, which makes it more and more difficult for people to distinguish the attack characteristics from the normal and legitimate network transport flow.

3. Finding security loopholes is faster and faster.

4. Higher and higher firewall penetration. Firewall is the main protective measure that people use to prevent intruders. But more and more attack techniques can bypass firewalls. For example, IPP (Internet Printing Protocol) and WebDAV (distributed authoring and translation based on Web) can be used by attackers to bypass firewalls.

5. The threat of increasing asymmetry. Due to the progress of attack technology, an attacker can easily use a distributed system to launch a destructive attack on a victim. With the improvement of deployment automation and attack tool management skills, threats will continue to increase.

6. It will pose a growing threat to infrastructure. More and more users rely on Internet to complete their daily business, and infrastructure attacks cause more and more concern. The infrastructure faces distributed denial of service attacks, worms, attacks on the Internet Domain name system (DNS), and attacks on or using routers.

After reading the above, do you have any further understanding of the current situation of sql injection attack applications? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
