DNS Security Considerations and the Alternatives to BIND

Without DNS, the Internet users cannot access the Internet without resolving all the hostname into IP address while at the same time other external networks also cannot access your public servers. If the web server becomes inaccessible, people ...

Denial-of-service attack
In computing, a denial-of-service (DoS) attack is an attempt to make a machine or network resource unavailable to its intended users, such as to temporarily or indefinitely interrupt or suspend services of a host connected to the Internet. A distributed denial-of-service (DDoS) is where the attack source is more than one–and often thousands–of unique IP addresses.Criminal perpetrators of DoS attacks often target sites or services hosted on high-profile web servers such as banks, credit card payment gateways; but motives of revenge, blackmail or activism can be behind other attacks.
