Compilation

Choose 1a or 1b depending on whether you want sources from a release tarball or the git repository.

1a) Get a release tarball

# replace ${version} with the desired version
wget https://fedorahosted.org/releases/o/p/openscap/openscap-${version}.tar.gz
tar -xzpf openscap-${version}.tar.gz
cd openscap-${version}.tar.gz

OR

1b) Get fresh sources from git repository and run ./autogen.sh

git clone https://github.com/OpenSCAP/openscap.git
cd openscap
./autogen.sh

The autoconf, automake, and libtool tools are required to be installed on your system.

2. Run the following commands to build the library:

./configure
make

Use cases

SCAP Content Validation

• The following example shows how to validate a given source data stream; all components within the data stream are validated (XCCDF, OVAL, OCIL, CPE, and possibly other components):

oscap ds sds-validate scap-ds.xml

Scanning

• To evaluate all definitions within the given OVAL Definition file, run the following command:

oscap oval eval --results oval-results.xml scap-oval.xml

where scap-oval.xml is the OVAL Definition file and oval-results.xml is the OVAL Result file.

• To evaluate all definitions from the OVAL component that are part of a particular data stream within a SCAP data stream collection, run the following command:

oscap oval eval --datastream-id ds.xml --oval-id xccdf.xml --results oval-results.xml scap-ds.xml

where ds.xml is the given data stream, xccdf.xml is an XCCDF file specifying the OVAL component, oval-results.xml is the OVAL Result file, and scap-ds.xml is a file representing the SCAP data stream collection.

• To evaluate a specific profile in an XCCDF file run this command:

oscap xccdf eval --profile Desktop --results xccdf-results.xml --cpe cpe-dictionary.xml scap-xccdf.xml

where scap-xccdf.xml is the XCCDF document, Desktop is the selected profile from the XCCDF document, xccdf-results.xml is a file storing the scan results, and cpe-dictionary.xml is the CPE dictionary.

• To evaluate a specific XCCDF benchmark that is part of a data stream within a SCAP data stream collection run the following command:

oscap xccdf eval --datastream-id ds.xml --xccdf-id xccdf.xml --results xccdf-results.xml scap-ds.xml

where scap-ds.xml is a file representing the SCAP data stream collection, ds.xml is the particular data stream, xccdf.xml is ID of the component-ref pointing to the desired XCCDF document, and xccdf-results.xml is a file containing the scan results.

Document generation

• without XCCDF rules

oscap xccdf generate guide XCCDF-FILE > XCCDF-GUIDE-FILE

• with XCCDF rules

oscap xccdf generate guide --profile PROFILE XCCDF-FILE > XCCDF-GUIDE-FILE

• generate report from scanning

oscap xccdf generate report XCCDF-RESULT-FILE > XCCDF-REPORT-FILE
