DNS name lookup

DNS monitoring techniques used by cloud providers are a great way to prevent malicious hosts. Because malware uses DNS to look up IP addresses to refer to sites hosted on bullet-resistant hosts, DNS lookup for suspicious queries can help find systems that link to a malicious site. A DNS name lookup can be altered by a DNS server to redirect a potentially affected endpoint to a secure site, alerting the endpoint it was trying to associate with a malicious site. The above facts will help protect your server from malicious attacks.
