Expanding the knowledge about DNS records, we can’t skip another of the essential DNS CNAME record.
The full name of the CNAME record is Canonical name record. The Canonical Name is demonstrating which exactly is the real name of a domain. In that direction of thought, the DNS CNAME record serves the purpose to point which is the true canonical domain name of one domain name.
Such a title is the introduction to a really heavy menu. Both are perhaps, the most dangerous attacks that can be implemented online. Consequences for targets are absolutely not pleasant. Servers’ outages lead to big losses in terms of time, money, users’ and partners’ trust.
Criminals’ purposes define the strength of the attack.
DoS is an online attack that uses an infected source to send big loads of traffic to its target with the clear objective of shutting it down. Users won’t be able to access it until the situation is fixed.
Attackers use traffic in big amounts because they know systems will be overwhelmed while trying to handle it. Also, the resources of the system will be highly demanded. Then users won’t be attended. Everything will slow down until the point of crashing.
Besides flooding systems with traffic, DoS can work by exploiting vulnerabilities that can lead the target to crash. Knowing those, criminals choose a weapon to attack, a proper input to be sent. That way, they destabilize the victim’s system until it gets offline.
This cyber-attack is executed to totally stopping systems’, servers’ or networks’ functionality. Again, the means to attack is traffic. But in this case, we talk about massive loads of traffic driven from multiple infected devices. That is why it is “distributed”. Attack sources can be located at different points of the world. This makes it more dangerous than a DoS attack.
Sluggishness is a symptom that can alert the target. It can fight back, but if it doesn’t succeed, it will be shut down, and the service for users will be denied.
DDoS attackers have developed and mixed different techniques to attack. Based on the final purpose they have, they can hit their target really strongly. What makes this threat possible is the huge amount of devices connected to the Internet that exists. And it increases every day. Computers, wearables, millions of Internet of Things (IoT), servers… can be infected by criminals to direct all the needed traffic to drown their victim.
There are important differences between these evil attacks.
Let’s start with a big one between DoS vs DDoS attack. In DoS, the attack is directed from one infected system to a target. This means the attack can be really aggressive, but the target can still have more defense chances because the battle is one-to-one. DDoS operates the attack using multiple infected traffic sources from more than one location, which makes it harder to stop it.
To track the system where the DoS attack is coming from is not hard for technology currently. But imagine the time and resources that it will take to track the multiple sources of a DDoS attack. And if you manage to stop some, many more will keep attacking at the same time.
DDoS gets its malicious objective of shutting down targets so much faster than DoS can. While attacking from multiple sources simultaneously, resources of the attacked system will be strongly demanded, defenses weakened, and it will turn off. It takes longer for DoS to reach that point.
Both attacks use traffic to saturate targets. But the amounts of traffic a DDoS can reach are far larger and more dangerous than the ones DoS can produce.
DoS and DDoS mix different techniques to attack for successfully reaching their malicious purpose. The good news is security tech already offers you defense methods against them. To enhance your security shield always will be better and cheaper than paying for fixing the consequences.
To properly understand DNS and its function, we must investigate each of the DNS records, how they work, and why they exist. There are many, but there are a few that we must understand from the start. This is why we will begin by explaining the DNS SOA record.
The DNS SOA record is the start of authority. It is the beginning of the chain of authority that the DNS has. It will point which server, from all the nameservers that you have, contains the original zone file. This server will be the authoritative DNS server, and it will have all the important information about the zone.
Inside the DNS SOA record, there you can find information about the zone transfer, the rate of refreshing, and the rate for retry if not refreshed properly. Also, inside it, you will see the DNS administrator’s contact information.
The domain name system (DNS) always has something in store for us to learn. From its architecture to its functionality, different components, and records. And exactly today, it is the turn of DNS MX recorded to be explained.
MX stands for mail eXchange record. DNS records are vital for giving instructions for different DNS processes to happen. A DNS mail exchange record (MX) is a resource record that the domain name system uses to point correctly to the exact name of the incoming e-mail server where e-mails have to be sent. Yes, you got it! MX record indicates the responsible server that has to get the e-mails sent to a determined domain.
These are the 5, most essential ways that you can use to improve your website’s security. Apply all of these ways, so you could have far fewer security problems than an average website owner. Better security means fewer problems and better business results.

Whether your website has an attractive design or great promotions for users, if loading time takes too long, they will leave, and maybe, they won’t get back.
Speed has become a critical factor in guaranteeing a satisfactory user experience and better ranking on the search engines.
Whatever we do, there will be failures. The computer can break down; the connection can get saturated; a bug can cripple a server, or whatever other reason can lead to a big problem. But can a person stay 24-hour a day monitoring our DNS servers? There is a better solution, a service that will monitor your DNS traffic and act if there is a problem, and it is called DNS Failover.
To park a domain means you put it on hold. It’s like you get a domain name, but you don’t relate it with services (web hosting, email). You park it to use it later, so it just shows a landing or holding page on it. Commonly, it displays a message that can be your contact info or a specific reason for the domain to be parked, “under construction”.
The Dig command is one of the most popular NSlookup alternatives for Linux and macOS. Here we will show you how to use it for checking your domain and all its DNS records.
DIG is an abbreviation of Domain Information Groper, and it is a software with a command-line interface for domain probing. You can find the command on almost every Linux distro like CentOS, Ubuntu, Debian, Linux Mint, and more.
If you plan to build a website or you are already looking for a web hosting service, you must read this.
Choosing a web hosting provider and a suitable plan is critical for you to succeed online. But many people don’t choose well, because they don’t clearly understand how this service really works. Of course, you can change provider and plan if your initial decision doesn’t work, but to migrate from service to service will take you time, effort, and money that, honestly, you can save.
