DNSSEC Public Signing Key helps protect Internet against malicious acts who can spoof or manipulate a domain by forging DNS record signatures. This is done by adding a layer to the DNS and storing cryptographic signs in DNS records such as A, AAAA MX, and CNAME.
What is the dnssec protocol?
Domain Name System provides global connectivity and has done so for decades. It is also the basis for a number of new protocols which require secure communication. These include Transport Layer Security (TLS) and encryption keys that can only be validated in zones signed with cryptographic signatures.
In the old days, it took six messages and a lot of data transfers to change the public key of a zone. This was a problem because the DNS could not scale up to the size of the Internet.
Luckily, the IETF re-wrote DNSSEC's code to resolve this issue. This version is called DNSSEC-bis and it uses "delegation signer (DS) resource records" instead of the original six messages. These DS record publish a public KSK fingerprint in the parent zones, and resolvers verify that fingerprint matches DS records from the child zones to authenticate legitimacy of child's key pair.
How does dnssec function?
Dnssec adds an extra layer of trust for DNS records. This layer is designed to ensure that any answer received from a valid DNS resolver corresponds exactly with the authoritative status of the records.
This allows a resolver to verify the authenticity and validity of a zone, by comparing its signatures to its public key. It can also calculate the corresponding signatures in its copy of these tokens. This is an essential step for DNSSEC to be reliable. It stops man-in-the middle attacks from injecting fake data into the network to deceive resolution processes.
The signatures are encapsulated in a "reverse redistribution service identity" (RRSIG) record, which includes timestamps that limit replay attacks. These RRSIG timestamps, unlike DNS TTL values which are relative to the time of sending records, are absolute. The signatures need to be regularly re-signed, and then distributed to secondary servers. Otherwise they are rejected by validating resolutions.
Registrants are required to support DNSSEC. They must also have tools that allow them to sign zones, upload DS Records, and manage key rollsovers. These services are available from webhosting providers, DNS management companies and registrars.

UI designers design websites by designing user interfaces (UI), and visual elements.
They also ensure that the site meets users' needs.
This includes understanding the information that visitors require and how the site should function.
Wireframes are created by UI designers using a variety of tools. Before they begin designing, wireframing allows them to visualize the page's layout.
It is easy to create your own wireframes using the online templates.
Some designers only focus on UI design. Others combine UI and graphic design.
Graphic designers use software such as Photoshop to edit images.
They then use Adobe InDesign to lay out pages and layouts.
Photographers capture images using digital cameras or DSLRs.
They then upload the pictures to a photo editing program where they add text captions, filters, and other effects.
Afterward, the photographer saves the image in a file format compatible with the website.
When building a website, it is essential to consider all aspects of the design process.
This includes research planning, wireframing and prototyping, as well as testing, coding, content generation, and publishing.
Research – It is essential to do extensive research before you begin a new project.
Planning - Once your research is complete, you can begin to create a plan.
Wireframing – A wireframe is a preliminary sketch or drawing of a webpage or application.
Prototyping -- Prototypes allow you to make sure that your final product is exactly what you imagined.
Testing - The prototype should undergo multiple rounds of testing to ensure it works properly.
Coding: Coding is the process of writing code for computers.
Content Creation – Content creation includes everything, from the writing of copy to managing social networks accounts.
Publishing is the act of uploading files and making sure that the site can be accessed.
You'll need to be able to understand the different projects you work on as a freelance UX/UI Designer.
Some companies may only need wire frames while others require complete prototypes.
You may be required to perform specific tasks depending on the project you accept.
For instance, if your job is to create wireframes you might have to make several over the course of time.
If you're hired to create a complete prototype, you may be required to develop a fully functional version of the site.
It doesn't matter what kind of project it is, strong interpersonal skills are essential.
You need to build strong relationships with potential employers as freelancers are hired primarily through referrals.
Furthermore, you should be able and able to communicate both verbally AND in writing.
