Vulnerability discussion

The System Integrity Protection is vital to prevent unauthorized and unintended information transfer via shared system resources, protect audit tools from unauthorized access, modification, and deletion, limit privileges to change software resident within software libraries, limit the ability of non-privileged users to grant other users direct access to the contents of their home directories/folders.SIP also ensures the presence of an audit record generation capability for DoD-defined auditable events for all operating system components, supports on-demand and after-the-fact reporting requirements, does not alter original content or time ordering of audit records, and does not alter original content or time ordering of audit records.Satisfies: SRG-OS-000051-GPOS-00024, SRG-OS-000054-GPOS-00025, SRG-OS-000062-GPOS-00031, SRG-OS-000122-GPOS-00063, SRG-OS-000138-GPOS-00069, SRG-OS-000256-GPOS-00097, SRG-OS-000257-GPOS-00098, SRG-OS-000258-GPOS-00099, SRG-OS-000259-GPOS-00100, SRG-OS-000348-GPOS-00136, SRG-OS-000349-GPOS-00137, SRG-OS-000350-GPOS-00138, SRG-OS-000351-GPOS-00139, SRG-OS-000352-GPOS-00140, SRG-OS-000353-GPOS-00141, SRG-OS-000354-GPOS-00142, SRG-OS-000480-GPOS-00228, SRG-OS-000480-GPOS-00230

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.
