Title

Session only-based cookies must be enabled.

Control

Verify the policy value for "Computer Configuration/Administrative Templates/Microsoft Edge/Content settings/Configure cookies" is set to "Enabled" with the option value set to "Keep cookies for the duration of the session, except ones listed in 'SaveCookiesOnExit'". Use the Windows Registry Editor to navigate to the following key: HKLM\SOFTWARE\Policies\Microsoft\Edge If the value for “DefaultCookiesSetting” is not set to "REG_DWORD = 4", this is a finding.

Discussion

Cookies must only be allowed per session and only for approved URLs as permanently stored cookies can be used for malicious intent. Approved URLs may be allowlisted via the "CookiesAllowedForUrls" or "SaveCookiesOnExit" policy settings, but these are not requirements.
