computer security programs

The topic of script security seems to be endless forever. If you often go abroad to various types of bugtraq, you will find that more than half of them are related to scripts, such as SQL injection, XSS, Path Disclosure, remote commands execution is a word that can be used only to catch bots? For those who want to do web security, it is best to learn it. But what we want is not fish but fish. In China, a va

Thinking logic of computer programs (73) and thinking 73 In this section and the following sections, we will discuss the container classes in Java and package. This section describes two simple classes, CopyOnWriteArrayList and CopyOnWriteArraySet, and discusses their usage and implementation principles. Their usage is relatively simple. What we need to understand is their implementation mechanism: Copy-On-

latter is more flexible than the former. 3. afxmessagebox does not control the message box title. It is often used for internal data output or warning during program debugging. MessageBox is more formal and often used in the application version to be submitted, you can control the title content without using an executable file name with unknown meanings as the title. Vi. SummaryThrough the preparation of this immune program, it has played a very good role. Although this immune program is of li

Thinking logic of computer programs (36) and thinking 36 In the previous section, we introduced the basic concepts and principles of generics. In this section, we will continue to discuss generics and the wildcard concepts in generics. Wildcards have confusing and confusing syntaxes, but they are widely used in Java container classes. What is it? In this section, let's analyze it gradually. More concise par

is reduced and the start time is slow? It is a small cost for obtaining enhanced security and faster development advantages of the Java platform. 　　Open source code alternative In addition to the standard licensed JVM (free of charge, but restricted by source code; available for Linux in the Sun, IBM, BEA, and Blackdown organizations), there are several other alternatives to Linux. These options include the "Clean Room" open source JVM implementation

So here are some tips for beginners if the computer doesn't respond when you're doing something important, do not go to the mouse, try to close the window, because the program has no response has been explained that the computer's internal program is not smooth, and then to point the mouse is equivalent to increase the burden of the computer, is tantamount to worse, you say no response to the program

Thinking logic of computer programs (87) and thinking 87 In the previous section, we discussed dynamic proxies. in the previous sections, we mentioned ClassLoader for many times. This section will discuss in detail the class loading mechanism and ClassLoader in Java. ClassLoader is the Class for loading other classes. It is responsible for loading bytecode files to the memory and creating Class objects. Lik

Thinking logic of computer programs (24) and thinking Logic The basic types, classes, interfaces, and enumerations we introduced previously are all used to represent and operate data. There may be many errors during the operation process, and there may be many causes of errors, some are uncontrollable internal reasons, such as insufficient memory, full disk, and some are uncontrollable external reasons, suc

String operations are probably the most common operations in computer programs. Java indicates that the String class is String. This section describes String in detail. The basic usage of strings

Thinking logic of computer programs (30), thinking Logic The previous section introduced the String, and mentioned that if String modification operations are frequent, StringBuilder and StringBuffer classes should be used. The methods of these two classes are basically the same, and their implementation code is almost the same, the only difference is that StringBuffer is thread-safe, while StringBuilder is

To prevent external access or control, the system encrypts the data, such as qq passwords, chat records, and user information in web programs. For open-source programs, algorithms are open, and Data Encryption relies only on keys to protect

The concept of membership is a relatively low level concept in human society, originated from the consciousness of a group. Similarly, when ASP. NET 2.0 programs start to develop applications involving member relationships, they must first understand the key concepts of identity, authentication, and authorization.

Thinking logic of computer programs (23) and thinking 23 In the previous series, we introduced the basic data types, classes, and interfaces used to represent and operate data in Java. This section discusses enumeration types in Java. Enumeration is a special type of data. Its values are limited and can be enumerated. For example, a year has four seasons and a week has seven days, although classes can also

To facilitate data operations, the advanced language introduces the concept of data types. Java defines eight basic data types, A class is equivalent to a custom data type. It can represent and
