Backup DNS is also frequently called Slave DNS, and it holds a copy of all the information for a domain, including DNS records. That copy is received right away from the Master or Primary DNS. You are not able to perform any modification, and it acts only for storing the data. In case you desire to make some additional changes to the data, you should make them in the Primary DNS. Then they are going to propagate to the Slave DNS as well.
“Ping of death” sounds like the title of a scary movie. And if we follow that idea, yes, it’s a dangerous cyberattack, and victims definitely won’t experience a happy end.
Ping of death is a cyber attack that belongs to one of the most dangerous categories that exist, the denial of service (DoS) attacks. It takes advantage of a specific vulnerability and the ping command use. That’s the origin of its name.

The Teardrop has been bringing down computers in the past, but should we still be afraid? How does it work, and is there a way to prevent a Teardrop attack? Now you can learn the most important information about this DoS attack.
The Teardrop attack (also known as TCP fragmentation attack) belongs to the group of the Denial-of-Service (DoS). The attack uses fragmented data packets sent to the target that can’t reconstruct them successfully and fail to function. The vulnerability that the Teardrop attack exploits can be found inside the TCP/IP reassembly process. Those Teardrop fragmented packets overlap each other, and the target crashes in its attempts to process them.
The Internet is a land with plenty of opportunities, where the most innovative seeds (businesses) can grow really big! But, unfortunately, the coin has two sides. And this is also a land with many risks, where survival is not easy. There are already many predators to be aware of, like the bloody DDoS attacks.
Let’s have a look at the largest DDoS attacks in history.
