Vulnerability discussion

Discretionary Access Control (DAC) is based on the premise that individual users are "owners" of objects and therefore have discretion over who should be authorized to access the object and in which mode (e.g., read or write). Ownership is usually acquired as a consequence of creating the object or via specified ownership assignment. In a DNS implementation, DAC should be granted to a minimal number of individuals and objects because DNS does not interact directly with users and users do not store and share data with the DNS application directly.

Check content

Verify that the core BIND 9.x server files are owned by the root or BIND 9.x process account. With the assistance of the DNS administrator, identify the following files: named.conf root hints master zone file(s) slave zone files(s) Note: The name of the root hints file is defined in named.conf. Common names for the file are root.hints, named.cache, or db.cache. If the identified files are not owned by the root or BIND 9.x process account, this is a finding.

Fix text

Change the ownership of the files to the root or BIND 9.x process account. # chown

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
