Understand hacker skills Uncover mystery hacker veil

In recent years, with the Internet in all aspects of life, the computer network virus seems to have become an enemy that netizens can't face. How to win in the fight against hackers and viruses, and protect our computers from infringement, this requires a certain amount of wisdom. Xiaobian feels that knowing oneself and knowing oneself can win every battle, so to defeat hackers, we must first understand hackers. We really set foot on the road of learning hackers. The first thing to introduce is the basic skills that must be mastered as a junior hacker. You can learn from this that hackers are not mysterious, and it is easy to learn.

First, understand a certain amount of English:

Learning English is very important for hackers, because most of the materials and tutorials are now in English, and the news about hackers is also from abroad. A loophole takes about a week from discovery to Chinese introduction. During this time, the network administrator has enough time to fix the vulnerability, so when we see the Chinese introduction, the vulnerability may be early. It no longer exists. Therefore, learning hackers should try to read English materials, use English software, and pay attention to famous foreign network security websites in time.

Second, learn the use of basic software:

The basic software mentioned here refers to two contents: one is the common computer commands we use every day, such as ftp, ping, net On the other hand, we must learn about the use of hacking tools, including port scanners, vulnerability scanners, information interceptors and password cracking tools. Because these softwares are many different types and functions are different, so this book will introduce several popular software usage methods. After learning the basic principles, learners can choose either their own or the major security websites. Find a guide to developing software and write your own hacking tools.

Third, a preliminary understanding of the network protocol and working principle:

The so-called "preliminary understanding" is "in accordance with their own understanding of the way" to understand the working principle of the network, because the agreement involves Knowledge is complex and complex, so if you conduct in-depth research at the outset, it will definitely dampen your enthusiasm for learning. Here I suggest that learners have a preliminary understanding of the tcp/ip protocol, especially how the network communicates information when browsing the web, how the client browser applies for “handshake information”, and how the server side “answers the handshake information”. “ accept the request & rdquo; and other content.

4. Familiar with several popular programming languages ​​and scripts:

As mentioned above, there is no requirement for learners to learn in depth, as long as they can understand the language and know the execution of the program. The result is ok. It is recommended that learners initially learn C language, asp and cgi scripting language, and also have a basic understanding of htm hypertext language and php, java, etc., mainly learn the "variables" and "array" in these languages, because the language There is an intrinsic connection between them, so as long as you are proficient in one of them, other languages ​​can be the same. It is recommended to learn C language and htm hypertext language.

V. Familiar with web applications:

Network applications include various server software daemons, such as wuftp, Apache and other server backends; and various online forums and e-communities . Conditional learners should make their own computers into servers, and then install and run some forum code. After some attempts, they will be sensible to understand the working principle of the network, which is much easier than learning according to * theory. To achieve twice the result with half the effort!

As a hacker, it requires a certain depth of technology, although with the development of technology, hackers continue to learn and try to use newer and better technology, for this reason, we also Constantly learn some new knowledge to deal with the challenges of hackers.
