Abstract
In one implementation, a network device is configured to monitor communications associated with an endpoint and identify domain name service messages in the communications. Subsequently, the network device receives a hypertext transfer protocol (HTTP) request and determines whether a destination internet protocol (IP) address of the HTTP request is present in or absent from the domain name service messages. When the IP address is absent from the domain name service messages, the HTTP request is modified to trigger increased security.
