​What is a Botnet?

Have you heard the word Botnet? Sounds scary, doesn’t it? It is a network of infected devices that cybercriminals use for their malicious purposes. In the world, there are millions of infected devices, maybe even billions, and they are just a few clicks away from attacking their next target!

​What is Botnet?

A Botnet is a network of infected devices (a.k.a. hijacked devices or zombie computers) that cybercriminals first infect and later use for various cyberattacks, including DDoS attacks, SPAM spreading, phishing attacks, and more. The term Botnet is a combination of two words. The first is “bot” short of “robot”, which means an automated machine, that can perform a specific task.

What does DNSSEC mean?

DNSSEC meaning

Domain Name Security Extensions (DNSSEC) is a great way to add an extra security layer to your domains. It is an advanced DNS feature, which attaches digital signature (DS) records to the DNS information. So, that way, it can establish the authenticity of the source domain name.

The purpose of which it is designed is to protect Internet users from falsified DNS data. An example of such a case can be a misleading or malicious address rather than the actual address you wanted to visit.

Once you enable DNSSEC, the DNS lookups will have to use a digital signature to prove that the origin of the site’s DNS is accurate. It is very helpful for preventing some types of attacks. In case the digital signature does not match, the browsers will not open the site.
