SCAP is a line of standards managed by NIST. It was created to provide a standardized approach to maintaining the security of enterprise systems, such as automatically verifying the presence of patches, checking system security configuration settings, and examining systems for signs of compromise.
The SCAP suite contains multiple complex data exchange formats that are to be used to transmit important vulnerability, configuration, and other security data. Historically, there have been few tools that provide a way to query this data in the needed format. This lack of tools makes the barrier to entry very high and discourages adoption of these protocols by the community. It's our goal to create a framework of libraries and tools to improve the accessibility of SCAP and enhance the usability of the information it represents.
- Library - OpenSCAP library provides API to SCAP document processing.
- Toolkit - oscap is a command line tool that provides various SCAP capabilities; for instance: configuration scanner, vulnerability scanner, SCAP content validation and transformation etc.
Specifications supported by OpenSCAP:
- XCCDF: The Extensible Configuration Checklist Description Format (ver. 1.2)
- OVAL®: Open Vulnerability and Assessment Language (ver. 5.10.1)
- Asset Identification (ver. 1.1)
- ARF: Asset Reporting Format (ver. 1.1)
- CCE™: Common Configuration Enumeration (ver. 5.0)
- CPE™: Common Platform Enumeration (ver. 2.3)
- CVE®: Common Vulnerabilities and Exposures
- CVSS: Common Vulnerability Scoring System (ver. 2.0)
Furthermore, OpenSCAP also implements technology that is not included in SCAP standards:
- SCE - the alternative check engine. Allows you to use familiar scripting language of your choice instead of OVAL for checks.
- scap-workbench - a tool with a nice graphical user interface that provides scanning (both local and remote machine), content customization and machine remediation functionality.
- SCAP addon for Anaconda installer, which is used in Fedora and Red Hat Enterprise Linux, for applying SCAP content in the installation process.
- SCE Community Content - set of various security configuration settings (security controls) expressed in standardized format. Each security control can be evaluated by a small shell script which is executed via SCE.
- SCC - a compiler used for SC. SC is a small language intended to make the creation of OVAL content easier. The SC language is more "human readable" than the XML of OVAL.
- secstate - a tool that attempts to streamline the Certification and Accreditation (C&A) process of Linux systems by providing a mechanism to verify, validate, and provide remediation to security relevant configuration items.
- ruby-openscap - an extension of Ruby language adding OpenSCAP scanning capabilities
