DNS security is a major problem that has plagued the Internet since its inception. DNS was designed with recursive resolutions to resolve addresses. Security is not an issue. DNS does not verify the authenticity of a response packet; recursive resolvers can only check if it appears to come from the same IP address. This weak authentication mechanism means that forgers can easily forge responses, leaving resolvers unable to detect them.
SRV records
SRV Records are used for DNS security. They can be added to domains. SRV records are typically provided by the host. These records are usually associated with the service name and priority number. Higher priority records will be reviewed sooner than lower priority records.
DNSSEC
DNSSEC entails that DNS servers must sign their responses to queries. This protects the identity of the application and prevents it from being changed by DNS servers. DNSSEC is available for both mobile and server devices.
DNS Tunnelling
DNS tunnelling utilities are designed to collect as much information possible from the requests and their responses. Therefore, requests and responses often have long labels or overall names. This can indicate that the domain is malicious.
DNS Hijacking
DNS hijacking is a form of cybercrime in which an attacker intercepts a DNS request and redirects it to a malicious DNS server. This malicious DNS server then returns the wrong IP address, which the attacker uses to redirect the user to a fake website. Although the spoof web site appears legitimate, it does collect sensitive information. In some cases, the attacker might also install malware onto the victim's computer.
NXDOMAIN Attack
DNS servers can be subject to many attacks, including NXDOMAIN Attacks on DNS Security. These attacks disrupt the name resolution of the domain and block access to all services. DNS servers can be overwhelmed by requests and may not have the resources necessary to handle all traffic.
Random Subdomain Attack
Random Subdomain Attacks are used to interrupt DNS record lookups. Botnets of infected computer computers are used to send malicious DNS query bots. Domain Name System Security Extensions for DNS Servers (DNSSEC), are used to prevent this. DNSSEC digitally signs data for validity. This authentication must be done at every level of the DNS lookup process from the DNS root up to the DNS client. DNSSEC is used in conjunction with SSL/TLS, to increase the security of DNS records.

How do I create my own website?
It all depends on which type of website it is. Do you want to sell online products, start a blog, build a portfolio, or both?
You can make an essential website using only HTML and CSS (a combination of HyperText Markup Language and Cascading Style Sheets). It is possible to make a basic website with HTML and CSS. However, many web developers recommend using a WYSIWYG editor, such as Frontpage or Dreamweaver.
If you don't have experience designing websites, hiring a freelance developer might be the best option. They will help you design a website that suits your specific needs.
A freelance developer may charge you either a flat-fee per project, or an hourly fee. The cost of hiring a freelancer varies depending on how much work they complete within a given timeframe.
For example, you might pay $50-$100 an hour to a company. Higher rates will be charged for larger projects.
A lot of freelance websites offer job listings. You can also search on those websites before you reach out to developers.

Can I use HTML & CCS to build my website?
Yes! If you've been following along so far, you should now understand how to start creating a website.
After you have learned how to structure a website, you will need to know HTML and CSS.
HTML stands for HyperText Markup Language. This is like writing a recipe. You would list ingredients, directions, etc. HTML also tells a computer what parts of text should be bolded, underlined or italicized. It is the language of documents.
CSS stands as Cascading Stylesheets. You can think of CSS as a style sheet for recipes. Instead of listing out each ingredient and instruction, you write down general rules for things like font sizes, colors, spacing, and more.
HTML tells the browser how to format a web page; CSS tells it how to do it.
Don't panic if either of these terms are confusing to you. Follow these tutorials, and you'll soon have beautiful websites.

How To
What is website Hosting?
Website hosting refers simply to the place that people visit when they visit a website. There are two types.
-
Shared hosting is the cheapest. Your website files will reside on a server belonging to someone else. When customers visit your site, their requests travel over the Internet to that server. The request is then handed to the owner of that server.
-
Dedicated hosting – This is the most expensive option. Your website will reside on a single server. Your traffic is private because no other websites have shared space on this server.
Most businesses choose shared hosting because it's less expensive than dedicated hosting. You can use shared hosting if the company owns the server to provide the resources required for your website.
However, both have their advantages and disadvantages. These are the key differences between them.
Sharing Hosting Pros
-
Lower Cost
-
It's easy to set up
-
Frequent Updates
-
It is available on many Web Hosting Companies
You can get shared hosting for as low as $10 per monthly. But keep in mind that this price usually includes bandwidth. Bandwidth is how much data you can transfer to the Internet. Even if you are only uploading photos to your blog site, high data transfer rates can still cost you extra.
You will quickly see why you paid so much for your former host once you have started. Most shared hosts provide very limited customer support. Their techs will occasionally walk you through setting up your site, but you're on your own after that.
It is important to find a provider that provides 24-hour support. They will attend to any issues you have while you sleep.
Cons of dedicated hosting
-
More Expensive
-
Less Common
-
Requires Special Skills
With dedicated hosting, everything you need for your website is at your fingertips. You won't worry about how much bandwidth you are using or how much RAM (random Access Memory) you have.
This means you'll have to spend more upfront. Once you get started with your online business, you will find that you don't require much technical support. You'll quickly become an expert at managing your server.
Which Is Better For My Business, So Which Is Better?
It all depends on the type of website you are creating. If you only want to sell products, then shared hosting might be the best choice. It's very easy to setup and maintain. Because you share a server, you will most likely receive frequent updates.
If you are looking to create a community around your brand, dedicated hosting is the best option. Instead of worrying about traffic, you can concentrate on building your brand.
