ObjectiveWhen the server is attacked by hackers, in most cases, hackers may modify some important files, such as system files, and so on. In this respect, we use tripwire to establish data integrity monitoring system. Although it can not protect against hacker attacks and hackers on some important files, but the change is able to monitor whether the file has been modified and which files have been modified, so that the attack after the targeted plan t
IntroducedWhen managing a networked server, server security is a very complex issue. Although you can configure firewalls, set up logging policies, buy security services, or lock apps, it's not enough if you want to make sure that every intrusion is blocked.A HIDS can collect your computer's file system and configuration, storing this information for reference and to determine the current state of operation of the system. If there is a change between the known safe state and the current state, i
Now that tripwire itself is fully ready, the next thing we need to do is use it to perform an integrity check.

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

Use the Logcheck tool to analyze all your logfile and avoid checking them manually every day, saving time and improving efficiency.

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 will cause the server to not execute CGI scripts or programs.

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