Control response
Mitigating Controls (NIST 800-53 r5) AI
Directly requires cryptographic protection of session cookies in transit, eliminating the cleartext exposure that enables hijacking when the Secure flag is absent.
Enforces secure baseline settings for web-application cookies (including the Secure attribute) so the misconfiguration cannot be introduced or persist.
Requires timely remediation of the software flaw (missing Secure flag) that produced the vulnerable cookie-handling behavior.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Encryption of data-in-transit directly prevents cleartext transmission while the control also addresses integrity and availability.
Enforcing hardened configuration baselines includes requiring the Secure flag on sensitive cookies.
Secure SDLC practices explicitly require correct use of security attributes such as the cookie Secure flag.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Specifying encryption and other security technology for network services prevents transmission of sensitive information in cleartext over potentially untrusted channels.
Mandating cryptographic protection and stronger authentication on public networks stops the transmission of plaintext sensitive information.
Specifying communications-security requirements and secure remote-access methods (including encryption expectations) prevents the transmission of sensitive data in cleartext over home or public networks.
Armoured conduits, electromagnetic shielding and locked enclosures make passive eavesdropping on unencrypted traffic traversing the cables more difficult, mitigating exposure of sensitive data in transit.
Use of cryptography control mandates encryption in transit, which HTTPS provides, but does not specifically require the Secure cookie attribute.
Application security requirements can include cookie security settings, but the control is broader and does not explicitly mandate the Secure attribute.
