in this project, you will implement a very simple system integrity verifier (SIV) for a Linux
system. The goal of the SIV is to detect file system modifications occurring within a directory
tree. The SIV outputs statistics and warnings about changes to a report file specified by the
user.
The SIV can be run either in initialization mode or in verification mode.
In initialization mode, the SIV program requires the user to enter a path to a monitored
directory, another path to a verification file (outside the monitored directory), a third path
to a report file and a hash function (e.g., the SIV must support at least MD-5 and SHA-1
message digests). The program will do the following:
a) Verify that the specified monitored directory exists
b) Verify that the specified location of the verification file and the report file are outside
the monitored directory
c) Verify that the specified hash function is supported by your SIV
d) If the verification file and/or report file exists already then they will be overwritten.
e) Recursively iterate through the directory contents (of arbitrary depth level) and for
each file/directory found record the following information in the verification file (it is
up to you decide the format used to store records in the verification file):
I. Full path to file/directory, including filename
II. Size of the file
III. Name of user owning the file/directory
IV. Name of group owning the file/directory
V. Access rights to the file/directory (either octal or symbolic)
VI. Last modification date
VII. Computed message digest with specified hash function over file contents
f) Write to the report file (this must be a text file) a summary of your findings:
I. Full pathname to monitored directory
II. Full pathname to verification file
III. Number of directories parsed
IV. Number of files parsed
V. Time to complete the initialization mode
Verification mode In verification mode, the user provides the path of the verification file and a path to a report
file. The program will do the following:
a) Verify that the specified verification file exists and, if true, begin parsing the file
b) Verify that the specified verification file is outside the monitored directory
c) Verify that the specified report file is outside the monitored directory
d) If the report file exists already then it shall be overwritten by the new report.
e) Recursively iterate through the directory contents (of arbitrary depth level) and
verify that it matches exactly the information from the verification file. A warning
must be printed to the report file for each entry that diverges from the records in the
verification file, along with information about what is different:
I. New or removed files/directories
II. Files with a different size than recorded (show old size and new size)
III. Files with a different message digest than computed before (show old digest
and new digest)
IV. Files/directories with a different user/group (show old user/group and new
user/group)
V. Files/directories with modified access rights (show old access rights and new
access rights)
VI. Files/directories with a different modification date (show old modification
date and new modification date)
f) Write to the report file (this must be a text file) a summary of your findings
I. Full pathname to monitored directory
II. Full pathname to verification file
III. Full pathname to report file
IV. Number of directories parsed
V. Number of files parsed
VI. Number of warning issued
VII. Time to complete the verification mode
The program is not allowed to change the verification file when executing in verification
mode.
