Security - Serie 1

Installation

Install it yourself as:

$ gem install file_checking

Usage in static mode: file_checking <task> <exception>

task can have three different values:

  • indexing (index all files but not folders in directory and sub-directories this tool is run)
  • analysing (analyse all files but not folders in directory and sub-directories this tool is run and which files have been modified, deleted or created)
  • help display this help message

OPTIONAL is the optional path of a file which indicate which file should not be indexed Each line of the file indicate the path relative to the current directory of a file which should not be indexed. For example, in your current directory you have the file not-to-index.txt. So you need to write in the file containing exceptions not-to.index.txt For prevented the file not-to-index.txt to be indexed

Usage in interactive mode: file_checking

You will be prompted to choose four tasks. The thirds one are these described above. The fourth is to quit the programm The path of the file containing the exceptions list will be asked in a second time (Leave it blank if you have none).

Note:

  • A file is modified if his content has changed but not his absolute path
  • A file is created if his absolute path is not indexed
  • A file is deleted if his absolute path is indexed but don't correspond with any file in current directory or sub-directories
  • Indexing is based on the MD5 algorithm

Limitations:

This program is mono-thread. For indexing a big amount of files, it can take hours
