A Basic Guide to SCAP

Posted March 24, 2011    Morey Haber

The Security Content Automation Protocol (SCAP, pronounced S-cap) is a suite of open standards that when referenced together, deliver an automated vulnerability management, measurement, and policy compliance evaluation for network assets. The first version of the suite specification focused on standardizing communication of endpoint related data and to provide a standardized approach to maintaining the security of enterprise systems. It provides a means to identify, express and measure security data in standardized ways such that products from multiple vendors can consume or produce SCAP content for correlation of security information. Each standard within the specification is individually maintained and provides revisions and updates independent of the SCAP specification.

Version 1.0 of SCAP includes the following standards and versions:

The draft version of 1.1 of specification expands the specification to include Open Checklist Interactive Language (OCIL, pronounced  O-sil) and changes specification to adhere to version 5.8 of the OVAL specification. OCIL is a new component that defines a framework for expressing a set of questions a user must answer and corresponding procedures to interpret responses to these queries.  OCIL was developed as a supplement for IT security checklists and is not restricted to IT security alone. It allows an assessment to occur and vital information entered that not can be observed electronically (i.e Is there a lock on the server rack door?). This information is then stored with the results to obtain a better picture of the assets security.

The two most common implementations of SCAP (so far) are for vulnerability assessment and configuration compliance. Using OVAL definitions, an SCAP compatible (certified) solution can ingest an XML file with vulnerability signatures or configuration benchmark checks and perform a local or network based assessment for systems that are non-compliant. The product will store the results of the scan in OVAL results and XCCDF results format and have references to CVE, CCE, CPE, and CVSS in the result XML file using standard nomenclature to describe the finding. Essentially, this process defines the check types and definitions using OVAL, and how those checks should be applied and reported using XCCDF, and that the contents of the results all contain the same parameters regardless of product. This makes interoperability between SCAP certified products possible for OVAL content creation to reporting on the end results and storage in a database.

Are Your Data Security Efforts Focused in the Right Area?

Posted January 28, 2015    Scott Lang

Vormetric Data Security recently released an insider threat report, with research conducted by HarrisPoll and analyzed by Ovum. Based on the survey responses, it is apparent that there is still a great deal of insecurity over data. However, the results also show that there may be misplaced investments to address those insecurities. I will explain…

GHOST Vulnerability…Scary Indeed

Posted January 28, 2015    BeyondTrust Research Team

A vulnerability discovered by Qualys security researchers has surfaced within the GNU C Library that affects virtually all Linux operating systems. The vulnerability lies within the various gethostbyname*() functions and, as such, has been dubbed “GHOST.” GHOST is particularly nasty considering remote, arbitrary code execution can be achieved. In an effort to avoid taxing DNS lookups, glibc developers introduced…

Your New Years Resolution: Controlling Privileged Users

Posted January 27, 2015    Dave Shackleford

Is 2015 the year you get a better handle on security? The news last year was grim – so much so, in fact, that many in the information security community despaired a bit. Really, the end-of-the-year infosec cocktail parties were a bit glum. OK, let’s be honest, infosec cocktail parties are usually not that wild…
