Prisma Session Cookies set by WAAS are encrypted and signed to prevent cookie tampering. In addition, cookies include advanced protections against cookie replay attacks where cookies are harvested and re-used in other clients.
Ban action is available in the App firewall, DoS protection and Bot protection tabs. If triggered this action would prevent access to the protected endpoints of the app for a time period set by users (default is set to 5 minutes.)
If Prisma Session Cookies are enabled, users are able to apply ban by either Prisma Session Id or by IP.

This option is intended to defend web applications running on remote hosts which can not be protected directly by WAAS (e.g. Windows Servers).
Remote host option is only available for WAAS host rules.
- A "middle-box" host instance with WAAS supported OS should be set up.
- Traffic to the web application should be directed to the "middle-box" host.
- Ports on the "middle-box" host to which traffic is directed to should be unused (WAAS will listen on these ports for incoming requests).
- Incoming traffic to the "middle-box" host will be forwarded to the specified address (resolvable hostname or IP address) by WAAS.
WAAS sets the original Host HTTP header value in the X-Forwarded-Host HTTP header of the forwarded request. The Host header is set to the hostname or IP mentioned in the WAAS settings.
