Interface (ACPI) and its programming language to enter rootkit code in BIOS memory, and hackers can even take advantage of the malicious features they write to replace the normal functionality in ACPI. The danger of such a BIOS rootkit attack is that it has no effect on the reboot and cannot be detected on the hard disk, even if reformatting the hard drive or reinstalling the operating system does not affect it. It does not exist in the form of a document. Every time the machine restarts, the e

: TripwireTripwire is one of the most well-known IDs implementations. Tripwire has compiled a database of system files and protected its configuration files and binaries with a set of keys. After the configuration of selections and exceptions is defined in detail, tripwire notifies them of any changes that occur to the files they monitor.Tripwire's strategy model is very flexible and allows you to shape its

, ensure that the data is not affected. Moreover, starting and running infected systems can only cause greater damage, especially when spam robots or similar software are running. Never forget tripwire The data integrity monitoring tool tripwire can be used to monitor file changes in a given Configuration System/directory. One of the main tasks of rootkit is to conceal the existence of malware. Normally, th

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

SSI also allows conditional execution of external programs, which attackers may exploit to allow the server to execute their malicious programs.

You can turn off the ability to execute an SSI file by using the INCLUDESNOEXEC directive in the access.conf file.

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

I have visited gamedev over the past few days and have reviewed almost all articles and posts related to scene management. I have benefited a lot from the discussion of various cool people and it is very useful for the design of research engines, list some particularly interesting posts and hope they will be helpful to you :) (the following order is different) (Update on 4.23.09) The technology of a 3D engine part 1, Part 2, Part 3 Scene Graph ResourcesHttp://www.gamedev.net/community/

, be cautious and be careful when your package is dropped! Citywide alert After the city wall is built, it is time to deploy the sentry. How can we monitor the health status of the server? There are still some tools available in linux. After some comparison, I finally chose tripwire. She can detect changes in key linux Files, such as files in the/usr/bin directory. So I configured a crontab and checked key files of the system every morning to see if t

2016 the eleven top-level network security conferences most worthy of participation With the rapid development of the information security market, annual information security conferences around the world have sprung up. However, corporate information security experts with urgent schedules can only choose to participate in a small number of high-quality security conferences, the following are the top-level security conferences recommended by Tripwire

systems trying to match complex patterns, most of which are only a small part of the key to matching attacks. 2. Use tabs in the command to replace SpacesBecause most of the current IDS systems do not check all the delimiters, using non-standard delimiters will escape IDs. In a Unix shell, you can also use "," instead of ";". Similar to the first one. Use tabs to run "tprof" instead of spaces. "tprof" appears in the command line ". In this way, the host or network-based IDS will discover this

during Apache installation and maintenance: 　　 Check whether the permissions of files and directories are appropriate. 　　 Whether the configuration files httpd. conf, srm. conf, and access. conf are set properly. 　　 Use password protection (. htaccess) for directories that require special protection ). 　　 Make the server log file as detailed as possible. 　　 Encapsulate the CGI script. If the CGI script is written in Perl, check its security in detail. 　　 Use TCP Wrappers and

intruders can report false intelligence to requests from the user space after controlling the operating system, without modifying netstat, ps, the binary files of the top and ls programs. Therefore, file system verification tools such as tripwire will be ineffective and cannot guard against the redirection function of knark. If the hacker connects hackme to cat, each time the cat is called, hackme is actually executing. In this way, cat is retained o
