What does a DDoS attack mean?
Distributed Denial of Service, which is for short, called DDoS, is a cyber-attack. It’s performed to disrupt essential targets like a network, system, or server. That is achieved by overwhelming them with lots of traffic, which is coming from many devices. The word “distributed” refers to the many various sources that are used to achieve the attack. When the target is down, the DDoS attack is complete. The outcome is simply not allowing any user to access it.
The DDoS attack can be of several kinds. Techniques can modify, or they could be mixed and accomplish a stronger hit to the target. Overall, any DDoS attack operates by infecting devices. If there are more connected to the Internet, more of them are going to attack the victim. This happens even globally and from any kinds of compromised sources like computers, servers, IoT devices, wearables. The target is not able to handle the traffic. It becomes sluggish and eventually becomes completely drowned.

What is a Secondary DNS service?
A Secondary DNS service is an addition to your Primary DNS service that provides extra name servers that have a copy of the zone file. Those servers will store the DNS records for your domain and resolve the domain when someone queries them. That way, they provide redundancy, better performance, hand increase your domain availability.

Ping of Death. It sounds as dangerous as it is. It can bring down your server and keep it that way for a long time using a simple tool like the ping command. A bit of modification of the packets of data and your server might have a serious problem.
What is Ping of Death?
Ping of Death or PoD is a Denial of Service attack (DoS attack) that uses a vulnerability connected to the ping command and the packet size. The attackers use the ping command and send data packets that are oversized. The normal size of an IPv4 packet of data, with its IP header, is 65 535 bytes, so everything that is above, like 65 536 bytes, will cause problems.

All types of cyberattacks are threats to take seriously. But DNS attacks directed to hit your DNS (domain name system) are like lethal RIP bullets impacting your system. Your online business can be fully damaged!
DNS cache poisoning.
DNS Cache Poisoning (DNS Spoofing) hits through the DNS resolver servers. They can temporarily save a copy of the DNS records related to domains in their cache memory. Those records get cached the time established in their time-to-live (TTL).

SSL certificate explained
An SSL (Secure Sockets Layer) certificate is a digital certificate that authenticates a website’s identity.
Secure Sockets Layer is an information file that generates an encrypted connection browser-server cryptographically. Once they connect, the SSL certificate is validated. That is the way to achieve protected communication between them. So, as a result, only the user and the website could access the user’s info, such as email address, payment details, etc.

DNS Spoofing explained
You can find DNS Spoofing, also called DNS poisoning. Don’t get confused. It is the same thing. It is a technique applied by hackers which includes imitating a device or a user. That is applied as a cover, with which the disruption of the regular flow of traffic or reaching protected data is not such a difficult task.

Cyber attacks are to be taken seriously. Even cute names can hide deadly poison. Today, let’s be aware of the smurf attack.
What is a Smurf attack?
A Smurf attack is a type of distributed denial of service (DDoS) attack. It took its name from the malware used to implement it, the Smurf malware. It targets computer networks to make them unavailable by exploiting vulnerabilities of the Internet Control Message Protocol (ICMP).
