Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Forcing a decision on every access request, including direct ones, reduces the exploitability of forced browsing by ensuring no unchecked access paths.
Forces all accesses through the reference monitor, preventing direct or forced requests that bypass checks.
Enforcing access for all logical requests prevents unauthorized direct access to protected resources.
Displaying the notification before further access on public systems prevents direct resource requests from bypassing the required system use terms and consent.
Decoy endpoints catch forced browsing and direct requests, deflecting attackers from legitimate resources while enabling analysis.
Blocks unauthorized direct requests or forced browsing by denying input access to non-authorized actors.
