A qualified Web security engineer is required to have a lot of knowledge, not only familiar with the website architecture, communication protocols, testing procedures and testing tools, vulnerability exploitation scripting, but also the accumulation of experience.

As the Internet enters the second half, the competition becomes more and more fierce, and there are not many hot occupations that can compete with artificial intelligence. The more developed the Internet is, the more serious the network security problems faced by major enterprises will be, and the talent gap of Web security engineers is still expanding. Economic theory reveals the market conclusion that the supplier is bound to increase the price when the demand is greater than the supply, which lays the market foundation for the high salary of Web security engineers.

Security technology is a fully quantifiable skill, and with the continuous improvement of Web security skills, the predictable average monthly salary will rise.

Essential skills of Web Security engineer

A qualified Web security engineer is to have a lot of knowledge, not only to be familiar with the website architecture, communication protocols, testing procedures and testing tools, vulnerability exploitation scripting, but also need experience accumulation, each ability needs to be carefully crafted, in-depth research, can be advanced to a higher level, the process without the guidance of predecessors, personal efforts and persistence.

1. Basic Network Protocol / website Architecture

The essence of the Internet is a series of network protocols. No matter it is based on network communication, whether it is Cpuma S architecture or Bhand S architecture, * personnel need to understand the communication process and the direction of data packets before they can use the corresponding means and tools to do it. The common protocols and request methods of Web sites, which are essential when doing *. It is even possible to use the protocol for testing. All knowledge is closely related and indispensable.

two。 Basic programming skills

A Web*** tester must have some basic programming skills, deal with code every day, and suffer a lot if he can't write or understand the code. For example, you need to write a tool suitable for the loophole in the situation. If you don't know how to write, it will greatly reduce your efficiency. In addition, it is about the follow-up advanced code audit problem, if you can not write the code, the code does not understand, then you do not know how to audit the loopholes from the source code to find the cause. For people who can only use tools and testers who can write code, under certain circumstances, the advantage can be realized.

3. * Test tool

* * there are many open source testing tools on the Internet, which is essential for testers to use * testing tools. Learn to use some excellent tools, and learn to write your own tools. For example, in doing * testing, such as a large amount of data FUZZ, manual operation will be a great waste of time and efficiency. If the tools on the Internet do not match the situation of this vulnerability, you will need to write your own manual tools to debug. Of course, there are many excellent tools on the Internet, and giving priority to the use of them will greatly improve our efficiency.

4. Understand the composition of the website

Try to understand the architecture, language, middleware containers and so on of a website. If you don't know how a website is built, there is no corresponding test solution when you do it. For example, a website uses some kind of middleware, or some database, or uses online open source CMS. If you do not understand these, then you can only wander around the web page, or even have no way to start. Understanding the construction and composition of a website is of great help to yourself in the early stage of stepping on points and information collection, so that you can get twice the result with half the effort.

5. Vulnerability principle (important)

* testers are sure to delve into the principle of vulnerabilities so that they will find more "interesting" things. All the interesting things are that it is possible for you to cooperate with other vulnerabilities on the original basic vulnerabilities, so as to achieve a combination of vulnerabilities, so that the effect may be better, but if you do not understand the principle of vulnerabilities, the generation of vulnerabilities, and do not start from the code layer, then you do not know the cause of the vulnerabilities, and it will be difficult to use and repair them in the later stage. At this time, you may need to check the information. It reduces the speed and efficiency in some form, so knowledge and accumulation are essential.

6. Report writing ability

Every time you finish a test, you need a test report, so the report writing ability is also indispensable. For the carding of their own loophole mining, the impression of the network structure deepens, which is a great help to communicate with customers in the later stage and to make suggestions for repair with developers. These small details determine the quality of your service and your sense of responsibility. So these are a process that needs to be constantly accumulated and improved.

Learning advice for entry-level Web Security Engineers

For students who want to get started with Web security, don't give up in the learning process, especially in the early stages of learning. At the same time, notes with pictures and texts should be taken in the process of learning. As the accumulation of knowledge, the most important thing is to practice, practice! It is not an overnight thing to find and solve problems in practice.

If you are interested in getting started with Web Security, the following book resources can be recommended to you:

"White Hat on Web Security", "White Hat on browser Security", "Sql injection and Defense", "XSS Cross-site script * * Analysis and Defense", "A book to understand TCP/IP" and "Metasploit*** testing Guide"
