The function principle of virus detection software

Computer virus detection software, usually from two aspects, effective detection of toxic files. 1. Closely monitor memory Ram area The monitoring of RAM mainly includes three aspects: (1) Tracking abnormal changes in memory capacity The memory capacity is represented by a word cell at the memory 0000:004bh. Normally, a word at this point represents the amount of memory in K. For example, if the memory

Intrusion Detection: The third force of Network Security

With the development of network security technology, apart from firewall and anti-virus system protection, intrusion detection technology has become an effective way to defend against hacker attacks. Although the intrusion detection technology is still evolving, the market for intrusion detection products is growing, and the third wave of network security has bee

A 3D Game collision detection Solution

Collision Detection on3DThe game is crucial. A good collision detection requires that the characters can be smoothly moved in the scene, and the steps within a certain height can automatically go up, while the high steps block people, when a slope with a small slope can be up, the slope is too large to block people, in the case of various forward direction is blocked, we should try to let the characters sli

Intrusion Detection Based on Wireless Networks

0. Introduction With the development of wireless technology and network technology, wireless networks are becoming a hot spot in the market. However, with the improvement of hacker technology, wireless LAN (WLAN) is under more and more threats. Wireless networks are not only attacked based on the traditional wired network's TCP/IP architecture, but may also be threatened by security issues based on the IEEE 802.11 standard. In order to better detect and defend against these potential threats, th

Measure the test taker's knowledge about how to use the intrusion detection system to prevent hacker attacks.

For the vulnerabilities in the intrusion detection system, let's take a look at hacker intrusion techniques. Once the network intrusion detection system is installed, the network intrusion detection system will analyze the online hacker attack events for you, and you can use the counterattack function of this intrusion detect
