Under the Linux platform, worms are rampant, such as ramen, lion, and slapper, which use system vulnerabilities to infect a large number of Linux systems, causing huge losses.Script virusThere are many more viruses that are written in the Shell scripting language. This type of virus is simpler to write, but the damage is equally shocking. We know that there are many script files in the Linux system that end in. SH,

In a typical Linux system, there are at least two directories or partitions that hold temporary files. One of these is the/tmp directory, and/var/tmp. In the newer Linux kernel system, there may also be/dev/shm, which is loaded with the Tmpfs file system. The problem with storing temporary files is that these directories can be a hotbed of zombies and rootkit that compromise system security. This is because in most cases, anyone (or any process) can

TCPView browses the TCP and UDP communication endpoints of each process (similar to Netstat on Unix). The company that produced the software has been acquired by Microsoft in 2005, so its future product line features are unpredictable. ----------------------------------------

most significant feature of a temporary file is its non-persistent, and in addition to security, you can focus on the other features or risks of the temporary file from the following perspectives: 1. location of temporary files Temporary files are usually created and stored in the default path, and in a typical Linux system, at least two directories or partitions maintain temporary files. One of these is the/tmp directory, and/var/tmp. In the newer Linux kernel system, there may also be/dev/s

Once we have completed all of the system recovery and patching tasks shown above, we can make a full backup of the system and services and save the new full backup separately from the old full backup. It should be noted here that for the purpose of the control system for intrusion activities, attackers will find ways to hide themselves from the user discovery. In addition to modifying or deleting systems and firewalls and other related log files, smart Hackers will also use some

From the simple backdoor of adding system Super User account to the use of system service loading, shared library file injection, Rootkit Toolkit, and even loadable kernel module (LKM), the backdoor technology under Linux platform is very mature and difficult to clear. is a serious headache for Linux system administrators.
