Each vulnerability is different, but it can be divided into local vulnerabilities and Remote

There are two types of Software defects that cause security problems: Deployment vulnerabilities and design defects. Most of the current focus in the software security market is on discovering and fixing vulnerabilities, mainly because the automated code review tool makes the process very simple. In fact, defects in software design and architecture also account for a large proportion, which accounts for 50%

Today, foreign media (the Register) reported that there was a huge design flaw in Intel's chips, and that Microsoft and Linux kernel developers were scrambling to fix it. Security vulnerabilities will eventually be fixed, but patches will slow down the PC (and MAC) chip speed. We don't know what the speed is going to be, but one developer says a 5% spin down is common-at least on Linux-and some tasks may slow down by as much as 30%. 　　What's going on?

vulnerabilities based on the information they collect and choose the best attack method for the selected target system. Denial of service attacks: Typically, hackers target specific systems and break into systems for specific purposes. The host security of those systems often prevents attackers from gaining control over the host. However, when a denial-of-service attack occurs, the attacker does not have to gain control over the system. The goal is t
