Abstract: A request from a computing device for accessing a resource is received by an edge server, where the request includes a cookie containing a first token value and a second token value. The edge server validates the first token value and a second token value using a third token value generated using hashing algorithm with a secret key and one or more other values. The edge server then compares the received token values with the third token value. When the request is validated, the edge server retrieves the request resource.

Abstract: Domain Name System (DNS) records of a single site are analyzed. A first one of the DNS records points to an IP address of a service. A second one of the DNS records is not pointed to an IP address of the service and is referencing the first DNS record. An electronic communication is transmitted to an operator for the single site that includes a notification that an IP address of the single site is exposed through the second DNS record.
