Rule 1: Never trust external data or input The first thing you must realize about WEB application security is that you should not trust external data. External data (outside) includes any data that is not directly entered by the programmer in the PHP code. Any data from any other source (such as GET variables, form POST, database, configuration files, session variables, or cookies) is untrusted until measur

I. Introduction of PAM Authentication moduleThe PAM authentication module is called a pluggable authentication module. An important function is to enhance the use of the SU Command control, with the help of the PAM authentication module, only a very individual user can use the SU command to switch. Pam provides a central mechanism for authenticating all services for login, remote login (telnet,rlogin,fsh,ftp), Su and other applications where the system administrator formulates different authenti

there is at least one possibility.The process of application security is like a process in which you can master your applications from getting started with bicycles. When you first get in touch with a bicycle, there is usually a confusion: Why don't two wheels fall? They even questioned whether they could learn it. After you have learned it, you don't need to worry about it. Any kind of inclination to fall

Some time ago, the security vulnerability of Google's input method in Windows Vista was booming. Many users have such questions from csdn, Microsoft and Chinese colleagues I know? Is this a Google input method implementation problem or a Windows Vista system vulnerability? We know that in windows, Applications Program All must be run under the corresponding user account. For example, if you log on as a common user and execute an

Preface Security data show that 2014 of the year, Android users infected with malicious programs 319 million people, the average daily malicious program infection reached 875,000. At the same time, Android applications have been cracked and pirated and other events are also emerging. It is clear that the Android platform has become the target of malicious programs and attackers, and more and more Android developers are beginning to realize the importa

advantage of the 80% probability." " DTCC solves this problem by running about 9 different test products on its software source code. These products include the appdetective of application security (for checking database vulnerabilities), and a tool from Whitehat (for scanning web applications). "We started this work three years ago because trends in data threats show that applications are more commonly

Sandbox, process, and permission In Linux, a user ID identifies a given user. on Android, a user ID identifies an application. The application is assigned a user ID during installation. The user ID remains unchanged during the lifetime of the application on the device. Permission is about allowing or restricting applications (rather than users) to access device r

Statement: I am not very familiar with this part. The solution proposed here is just an idea of my younger brother. I hope experts from all parties can help me identify the problem. Difficulties: In normal times, web applications and websites generally have the user login function. Therefore, the logon password must be involved. How can we ensure that the user's password will not be obtained by third-party attackers? There must be more ways to break the law. For advanced users, they can

This article was intended to be written since very early last year and has never been available. It was just a short time when a salon talked about such things.In the past, security enthusiasts often studied local app security, such as remote control, application cracking, and information theft,Most people have not noticed the

Android Application Security-Data Transmission SecurityAndroid usually uses a Wi-Fi network to communicate with the server. Wi-Fi is not always reliable. For example, in an open or weak-encrypted network, the access provider can listen to network traffic. Attackers may set up WiFi phishing on their own. In addition, after obtaining the root permission, you can also listen to network data in the Android syst

As more and more people send confidential information through e-mail, it becomes increasingly important to ensure that documents sent in e-mail are not forged. It is also important to ensure that the messages sent are not intercepted or stolen by anyone other than the addressee. By using the digital ID of Outlook Express, you can prove your identity in an electronic transaction, as if you were to show a valid document when you pay a cheque. You can also use digital IDs to encrypt messages to pro

login:.To summarize:In the process of transferring trust information from a high trust domain to a low trust domain, the non-reversible hash encryption process can effectively control the high trust level of information that spreads directly to the lower trusting domain. Suppose there are multiple levels of such a scenario in a system. That should be done more than once using irreversible encryption.Note:1) The above mentioned one irreversible cryptographic processing does not mean that it can
