  • Check the version of Apache currently installed on the server.
  • Check the version of PHP currently installed on the server.
  • Check whether the kernel version is update
  • Check for bad disk blocks in all partitions using SMARTD Health Check
  • Clean Spam, Frozen and unwanted mails in mail queue
  • Scan for suspicious files using maldet / clamav
  • Scan for files and directories with no user associated with them
  • Check for unsafe file permissions and Disabling some executables
  • Check the memory/CPU (system health check using systat)
  • Scan for files and directories with world-writable permissions

  • Check server load and partitions to perform maintenance activities
  • Scan for *.c or binary files (which have possible security issues)
  • Check dmesg output
  • Check history for root and su user
  • Change the permission of a directory and its subfolder to default permission
  • Examine common linux log files
  • Check tcp connections and make sure no unwanted ips or ports are listed
  • Check for Chargen

  • Performance checks
    iostat reports CPU, disk I/O, and NFS statistics
    vmstat reports virtual memory statistics
    mpstat reports processors statistics.
  • Turn off compilers. Most rootkits come precompiled but not all of them do. It will also prevent shell users from trying to compile any irc related programs.
  • Enable PHP open_basedir Protection : PHP open_basedir protection prevents users from opening files outside of their home directory with php.

  • Updated rules for mod security
  • Logcheck installation
  • Update php­pear and gem modules
  • Tackle down the currently infected files on the server by using AUTOBOTS
