Rosecheckers Code

These checkers enforce the CERT C Secure Coding rules, and are freely available from their SourceForge project. For questions regarding the CERT ROSE checkers, contact secure-coding at cert dot org.

Running Rosecheckers (the ROSE CERT C Checkers)

Checkers for CERT C secure coding rules/recommendations/guidelines are built into a tool called Rosecheckers, which uses the ROSE compiler. The program is run using all-lowercase 'rosecheckers'.
To run the Rosecheckers program on a C or C++ file, simply pass the file as an argument:

rosecheckers hello.c

If the C file violates some secure coding rules, the Rosecheckers program will print them out. If the Rosecheckers program can not find any violations, it prints nothing.

Rosecheckers actually takes the same arguments as gcc. So if your code has special flags that must be passed to the compiler, such as locations of include files, you can pass them to Rosecheckers in the same manner as gcc. Likewise, if you have a makefile that indicates how your program is to be built, you can run ROSE on your source code merely by instructing to your make command to use Rosecheckers as a drop-in replacement for gcc. One way to do this is:

make CC=rosecheckers

There are three ways to run Rosecheckers. You can run Rosecheckers using a downloadable virtual machine. You can build Rosecheckers, as well as ROSE itself, from source. Finally, Rosecheckers is available on Carnegie Mellon University's Andrew system to students, faculty, and staff.

Getting Rosecheckers code from source

You can get the rosecheckers code from source (no VM) from https://github.com/coruus/rosecheckers

If you install rosecheckers code from source, you will should install ROSE first. After installing ROSE:

• Clone the rosecheckers repository from github
• Set the ROSE environment variable to point to the directory for ROSE that has the bin, include, etc. for ROSE
• To build the Rosecheckers program from the CERT C Checkers, go into the rosecheckers/rosecheckers directory and type: make pgms

Rosecheckers on a Virtual Machine

To run these checkers, you must use a virtualization system such as VMWare. The Sourceforge project provides a free example VM.

Once extracted, the rosebud directory is a VM image that can be powered on by VMWare. After logging in, you'll need to enter your login password again when the system asks for a sudo password. This is so the VM image can generate a unique SSH key.

After that, you should be able to access the VM from your host machine remotely using SSH. You'll need the VM's IP address for this, which you can learn with this command from the VM:

ip addr | grep /24

If it provides multiple IP addresses, select the one that begins
/192.168.../.

In the VM's home directory, there is a README file explaining what software is available there. It includes both ROSE and the CERT Secure Coding rule checkers.

Building Rosecheckers

To build the Rosecheckers program from the CERT C Checkers, type:

make pgms

To test Rosecheckers on the code samples from the CERT C Secure Coding Rules:

make tests

To build API documentation pages, you must have doxygen installed:

make doc

To clean documentation pages and build files:

make clean

Rosecheckers on Andrew

To run Rosecheckers this way, you must have an Andrew account at CMU, usually limited to faculty, students, and staff. The Rosecheckers program is available in:

/afs/andrew/usr/svoboda/public/c_rules

To run Rosecheckers, you simply add this directory to your PATH environment variable.

Secure Coding Rules Enforced by Rosecheckers

The C Secure Coding Rules are freely available.

Here is a breakdown of how thoroughly Rosecheckers enforces the C Secure Coding Rules:
