to which push needs to be droppedRetf This method lets you jump to a code snippet that has a lower privileged level. At the same time we need to provide two different stack segments for two different privileged levels of code snippets. However, because of the boot sector space limitation, it is no longer possible for the code to declare a space to be used as a stack, but rather to specify the unused memory as a stack using the macro directly. #define stackspace 0x7c00 //stack address #defin

Privileged transfer is more complex, but it can be summed up into two main classes.1. For code snippets, you can only access from low to high.2. For data segments, only high to low access. And then decompose:Code snippets are from low to high (consistent, target privilege level to visitor privilege level) or the same (

Tell me about some of the privilege of the 2000.

Serv-U securely to ensure the security of Serv-U and even servers. Come with me. "Go, go, go... "(CS has been playing a lot recently. Hee: P) Solution body: 1. We all know that Linux and UNIX systems are more secure than Windows systems because Linux and UNIX system services do not use root permissions, but are used by another individual user with relatively low permissions, for example, the Web Service uses the nobody user. By default, Serv-U runs as a system, and the system's built-in acc
