Mitigating Controls (NIST 800-53 r5) AI

AC-3 directly enforces logical access authorizations on resources, stopping unauthorized parties from reaching sensitive files stored under the web root.

AC-6 limits granted privileges to the minimum needed, reducing the chance that web-accessible paths expose sensitive data.

PR.AA-05 full match
prevents

Enforcing least-privilege access permissions directly prevents unauthorized retrieval of sensitive files stored under the web root.

PR.DS-01 mostly match
prevents

Protecting confidentiality of data-at-rest mitigates exposure of files that should never have been placed under the web root.

PR.PS-01 mostly match
prevents

Hardened configuration baselines and change control prevent placement of sensitive files in publicly served directories.

mitigates

Secure architecture principles discourage storing sensitive data in publicly served directories.

mitigates

Technical access restrictions can block direct HTTP access to sensitive files under the web root.

mitigates

Classification identifies sensitive data so it can be placed outside the web root.

mitigates

Access-control policy defines who may reach files under the web root.

mitigates

Granting only the minimum rights prevents unauthorized retrieval of sensitive files.

mitigates

Secure SDLC practices include placing sensitive data outside the document root.
