cia forensics

Brief introduction:　　Kali Linux is a Debian-based Linux distribution that is primarily used for penetration testing and hacking, designed for use in digital forensics operating systems. Maintained and financed by Offensive Security Ltd. The first Mati Aharoni and Devon Kearns by offensive security were done by rewriting backtrack, the Linux distribution they had written before for forensics. 　　Get ready:

language structure is clear and simple, the library is rich, mature and stable, scientific calculation and statistical analysis are very strong, production efficiency is much higher than c,c++,java, especially good at strategy backtesting.

Recently began to learn Python3 web crawler development direction, the beginning of the textbook is Cia Qingcai "Python3 Network crawler developmentpractice," as the temperature of the contents of the learning is also to share their own operation of some experience and confusion, so opened this diary, is also a supervision of their own to learn. In this series of diaries I will always add some of the books do not have the content as a supplement to th

Here is a few ideas:Games codecademy --walks you through making a couple of the simple games. Pygame Tutorials --Pygame (the Python library for making games) has a good list of tutorials Making Games with Pygame--the book looks like a great the to learn Python by Making Games Websites Flask Tutorial -The official Flask (Simple Python web framework)

Some people say that the QQ account appeals process "Wonderful" is the other as much as possible to collect your information, so that it is safe, because the password is easy to be stolen, and your so much information is not easy to be stolen. That's only half the way to know. The real security system is a security system that is coordinated with the entire society. Instead of doing everything on their own (of course

profitable. For example, a British electronic gaming website was reported to have been paralysed by DDoS attacks after rejecting demand for ransom. The attacks from unethical business rivals are more widespread than they are imagined. A job search found that more than half of all DDoS attacks on American companies were proposed by competitors to gain an unfair commercial advantage. Ideological incursions can be suggested by the government or grassroots hacker activists. Hackers have been know

Welcome to the world of Python!Python is a high-level programming language that has applications in the fields of Web programming, scripting, scientific computing, and artificial intelligence.It is very popular and is widely used by prominent organizations such as Google, NASA, the CIA and Disney.——————————————————————————————————————————————Python runs the code in real time through the interpreter, You do not need to compile the code before executin

The basic principle of reptiles Crawlers are automated procedures for acquiring and retrieving Web pages and storing information . Get Web page:Access to the Web page is to obtain the source code, as long as the source to get down, you can extract the desired message Crawler process: Want the site's server to send a request, the return of the response body is the source code of the Web page. ? ==>1, the construction request is sent to the server ===>2. Accept Response and resolve

The server provides a file download, typically using a URL pointing to a file in the server to provide downloads. But this can not be statistics, permission detection and other operations. Therefore, the general use of PHP to provide downloads, the code is as follows: process Chinese file name: Use PHP ReadFile, need to go through the PHP layer, if you can directly through Apache to send files to the user, not through the PHP layer, will improve download speed. use Apache mod_xsendfile, d

In that case, the data may not only come from the system administrator, because the client program needs to use the provided services, and system vulnerabilities may allow intruders to control the computer.This is why security is the most fundamental problem in the entire system lifecycle from planning to removing the system. But what exactly does security mean?Generally, data security and sys
