Enterprise Information Portal: Enterprise Information Portal, which effectively integrates and publishes data collected and processed by various internal information systems. An EIP is an application system that enables enterprises to release various internal and external information and allow customers to access their personal information from a single channel. Customers will use this personalized infor

In section 1.1 we say that we can use stack overflow to destroy the contents of the stack, and in this section we'll look at how to scramble for the return address (EIP) so that we can control its value at will, so we can program it. Take a look at a classic program:The Get_print function of this program defines an array of size 11 bytes, under normal circumstances our input should be up to 10 characters (there is also a \ s terminator), and the Get f

EIP, EBP, and ESP are system registers, and some addresses are stored in them.The reason is that the three pointers are inseparable from the stack implementation in our system. We talked about the data structure of the stack on DC, which has the following features. (This emphasizes too much) In fact, it has the following two functions: 1. the stack is used to store temporary variables and intermediate results transmitted by functions. 2. Operating Sys

issued a corresponding interrupt signal, then the CPU will suspend execution of the next command to execute the order to execute the processing program corresponding to the interrupt signal, If the previously executed instruction is a user-state program, then the process of the conversion will naturally occur from the user state to the kernel state switch. such as the completion of the hard disk read and write operation, the system will switch to the hard disk read and write interrupt handler t

Here, we can simply modify the return address of any function, and customize the EIP point to execute any commands of the current process space. Here, we just make everyone better aware of the stack frame structure, there are no Inline hooks related to cross-process operations. Later, we will explain how to read any process memory and modify the execution process of any process function. If you don't talk much about it, just serve it directly: # Incl

1. Foreword Due to the openness of Internet and the limitation of the original design of communication protocol, all information is transmitted in clear text, which leads to the security problem of Internet increasingly serious. Illegal access, network attacks and so on frequently, to the company's normal operation brings security hidden trouble even immeasurable loss, therefore must use the information security technology to ensure the network security problem. 2. Network Solution Description T

[System Principle] Campus Network Network system can be divided into Campus networks Center, teaching subnet, office subnet, library subnet, dormitory area subnet, logistics subnet and the original cable TV network transformation access network. The construction of campus network should follow the three principles of practicality, expansibility and reliability of the system: 1. Practicality: Education is an investment-oriented industry.

Security needs to be thoroughly understood and mastered, both in development and during interviews or technical discussions. GoalThe goal of this tutorial is to give you an idea of how you should protect your own built WEB applications. Explains how to defend against the most common security threats: SQL injection, manipulating GET and POST variables, buffer overflow attacks, cross-site scripting attacks, data manipulation within the browser, and remote form submission.Quick Introduction to Sec

Recently, a friend asked me how to add a domain name email address, so I sorted it out and posted it. It is very specific. You can compare it directly. What is a domain name mailbox? Suppose you have your own domain name. By setting the domain name DNS, you can create a mailbox with your own domain name as the mailbox suffix. Google, QQ, and Netease now provide similar applications. Google's domain name mailbox is part of Google's enterprise application
