than 40 years ago, even though we still rely on operating systems designed decades ago. This is the challenge for Linux developers. To ensure Linux security, software engineers must insert security components around the Linux ker

security in the computing field. Platform-independent environments such as OpenOffice.org, Perl, and Firefox are not spared. For example, Dropper. MsPMs-a malicious Java archive (JAR) file was found on machines running Windows, Mac OS X, and Linux. Some malicious packages are specially written for GNU/Linux. Rootkit is a collection of tools that allow attackers

sell after-sales services. Therefore, the free software they use can be downloaded on their website (of course, the tool software developed by each vendor is not the GPL authorization software !). However, you can purchase their Linux CD. if you purchase the CD, they will provide the relevant manual instruction files,

As an open operating system, Linux is favored by many programmers. Many senior programmers prefer to write software related to the Linux operating system. This makes the Linux operating system rich in software support, and countless technical staff as technical support, whic

measures may be required. In the complete security audit process, we can connect our Linux server hard disk to another computer and check all the files on it manually or using mainstream Linux anti-virus software. In some cases, if the server suffers a serious fault, starting the computer through an external hard disk

copies/etc/passwd and then uses the dictionary file to unlock the password. 20. Thieves covet root permissions through Super User programs such as su or sudo. 21. Hackers often use Buffer overflow to manually intrude into the system. 22. cron is a tool used by Linux to automatically execute commands, such as regular backup or deletion of expired files. Intruders often use cron To leave backdoors. In addition to regularly executing broken decoding to

related derivative of the Java language. CLR may allow C # to be used on many platforms. CLR also provides many JVM execution-time security features (despite escaping from the exit that seriously weakens security assurance ). Microsoft. Net also supports the option to pre-compile the code into the local program for faster startup, which is the same as what GCJ does for Java bytecode. Of course,

cause any problems. In many cases, the entire/usr directory tree should also have unchangeable attributes. In fact, in addition to the chattr-R + ii/usr/command for the/usr directory, you can also use the ro option in the/etc/fstab file, load the partition of the/usr directory in read-only mode. In addition, setting the system log file to only append-only makes it impossible for intruders to erase their traces. Of course, if you use this security mea

Call server drive from external Mount The steps mentioned above are more than enough to cope with the risks in most Linux Server deployment, including web pages, emails, DNS and database tasks. however, if our Linux server stores sensitive information such as financial or important confidential files,

software packages During system planning, the general principle is to remove all unnecessary services. By default, Linux is a powerful system that runs many services. However, many services are not required and may cause security risks. This file is/etc/inetd. conf, which defines the services to be listened to by/usr/sbin/inetd. you may only need two of them: te

Linux as a free, open symbol, more and more users of the attention, but the real use of less personal users, mainly because of its system characteristics, and the surrounding software developers less, so that it only in the server system in the field of popularity. It's security protection, I do a little introduction: 1. Prohibit access to important files

on many platforms. CLR also provides many JVM execution-time security features (despite escaping from the exit that seriously weakens security assurance ). Microsoft. Net also supports the option to pre-compile the code into the local program for faster startup, which is the same as what GCJ does for Java bytecode. Of course, Linux users cannot directly use this

Thanks to the excellent network functions of the Linux operating system, most website servers on the Internet use Linux as the main operating system. However, because the operating system is a multi-user operating system, Hackers often choose Linux as the first target to attack in order to hide themselves in the attack. So, as a
