The so-called rootkit is a type of tool frequently used by intruders. Such tools are usually very confidential and difficult for users to notice. Through such tools, intruders have established a way that can always intrude into the system or control the system in real time. Therefore, we use the free software chkrootkit to establish an

Thanks to the speed and reliability of the 802.11n technology, many companies are starting to use a wireless LAN with larger bandwidth to support new mobile services. However, this change requires more complex and reliable WLAN tests to verify network security, connectivity, and performance. Companies no longer need human tools to check for signal strength, server accessibility, and Wi-Fi vulnerabilities. Tests hundreds of thousands of access-side APS distributed across the enterprise network ge

Many people think that as long as the operating system is reinstalled, the virus can be completely removed.　　 But do not know that after the operating system reinstall, due to security settings and patches are not installed in time and so on, the most likely to cause the virus to invade, so some necessary complementary measures are very critical. first, do not rush to access the network after installing

Many people think that the virus can be completely cleared if the operating system is re-installed. However, I do not know that after the operating system is re-installed, due to security settings and patch installation failure, the virus is most likely to be infiltrated, therefore, some necessary supplementary measures are critical.1. Do not rush to access the networkAfter Windows is installed, do not imme

Group PolicyIt is a must-use tool for network administrator management systems. I believe everyone is familiar with group policy application skills, but we can also find new application skills from group policies. The specific content is as follows. Applications in the computer run according to the system time. If the virus modifies the Windows system time by itself, the operation of anti-virus

I found a website, which is a regular intrusion. Well, its FINGER is on, so I compiled a SHELL and the aaa account tried zzz (by the way, this is an online rule I found, that is, the length of the account is proportional to the strength of the password. If an account has only two or three digits long, the password is generally very simple, and vice versa, so it is also called the owner's theorem ), as a result, an account does not exist. I did not try

Sandboxie is a more popular security aid tool, using the technology called "sandbox". The main principle is to have the application run in a separate space and not allow applications to modify other programs and data. The changes that the application makes in the sandbox can all be undone, and the resulting change can be removed at any time. Sand box schematic diagram Applications running in the sandbox do not modify the system registry or perform
