programs. Obviously, when running from a non-writable external device, they are more trustworthy tools, such as running from a CD or write-protected USB drive. I like the SD card because of the write protection switch. These two programs can search for known rooktkit, backdoor, and local vulnerability exploitation programs, and discover limited suspicious activities. The reason we need to run these tools is that they can view/proc, ps and other important activities on the file system. Although

PLUG-GW, because PLUG-GW do reverse IP lookup, If it is not found, record a warning message to the/var/log/maillog,logcheck default record all these warnings are sent to you, and you can ignore them by setting them. Use the Logcheck tool to analyze all your logfile and avoid checking them manually every day, saving time and improving efficiency. Third, tripwire Tripwire is a very useful tool for verifyin

Tripwire (http://www.tripwire.org ). The program periodically detects system files to determine if they are changed. 　　 If any unexpected change occurs, Tripwire generates a report for the user. To make Tripwire work properly, it takes some time to configure it, but it is indeed worth the time. 　　 A very important way to understand the system situation is to vie

1. aide OverviewAdevanced Intrusion Detection Environment (Advanced Intrusion Detection Environment) is an Intrusion Detection tool used to check the integrity of text. AIDE can construct a database for a specified document. It uses aide. conf as its configuration document. The AIDE database can store various attributes of a document, including permission, inode number, user, and group), document size, last modification time (mtime), Creation Time (ctime), last access time (atime), increased siz

connections are usually allowed. Finally, we should record all the prohibited connections to detect possible attack attempts. However, broadcast and multicast data packets should be discarded because these data packets may soon be filled with system logs. The following is an example of ipchains configuration (protecting the independent server system ): Bash # ipchains-lChain input (Policy deny ):Target prot opt source destination portsDeny all ------ 0.0.0.0 anywhere N/Deny all ------ anywhere

Many network administrators who are new to Linux have found that it is difficult for them to switch from a click-based security configuration interface to another interface based on complex and unpredictable text files. This article lists the seven steps that administrators can and can do to help them build more secure Linux servers and significantly reduce the risks they face. Ask the network administrator
