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
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

Other security Tools
Using TCP wrappers and tripwire can provide additional protection for your system. You can use the TCP wrappers to control Telnet or FTP access rights. Tripwire is a data integrity detection tool that can help system administrators monitor whether the system has been altered, and you can set up a specific policy in the Tripwire configurat
with the root permission. Perl scripts are restricted to running under a specific directory.
9: Server-Side security des (SSI) Security
With SSI, programmers can create common routines and include them in their code as needed. SSI also allows conditional execution of external programs, which attackers may exploit to allow the server to execute their malicious programs. Use the IncludesNoEXEC command in the access. conf file to disable the SSI File Execution function. However, this command wil
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

. SSI also allows for the conditional execution of external programs that an attacker could use 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. However, this instruction will cause the server not to execute CGI scripts or programs.

In the design of various communication devices and terminal electronic products, more and more embedded systems are used to make the products have more powerful functions, as are WiMAX wireless communication devices. Therefore, when designing and developing security technologies in modern network and communication technologies, they must be integrated with embedded technologies. In this paper, a solution of WiMAX wireless access device encryption technology based on AES-

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
