The internal DoS / Proactive Bot Defense cookies are set without the 'secure' flag on HTTPS deployments. The relevant cookies are only internal ones that are used to maintain the state; they do not contain any user-data or any sensitive information.
Any of the Client-Side features are enabled in the DoS profile: Client-Side Mitigation, Proactive Bot Defense, or Device-ID-based detection. This is only a problem for deployments that use HTTPS.
The DoS / Proactive Bot Defense cookies can now be optionally set with the 'secure' flag, according to these new DB variables: DOSL7.use_secure_cookies enables the 'secure' flag on cookies that are set on a Virtual Server with a client-side SSL profile (default disabled). DOSL7.assume_https assumes HTTPS on all Virtual Servers, even those without an SSL profile (default disabled). This may be used in case the SSL proxy is performed on a different Virtual Server, or a different device.
