DNS security has been an ongoing problem for the Internet over many years. DNS's basic design relied on recursive address resolvers to resolve IP addresses. Security was not considered a primary concern. DNS doesn't verify the authenticity or origin of a response packet. Recursive solvers can only confirm that the packet appears to be from the same address. Because of this weak authentication mechanism, forgers can forge responses easily and resolvers are 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. They are often associated to the service number and the name. Higher priority records get reviewed faster than lower priority records.
DNSSEC
DNSSEC is a mechanism for DNS security that requires DNS servers to sign their responses to queries. This protects the identity of the application and prevents it from being changed by DNS servers. DNSSEC can also be deployed on mobile devices or servers.
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 a malicious domain.
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. The attacker then redirects the user to a fake site by using the incorrect IP address returned by this malicious DNS server. The spoof site looks like a legitimate site but collects sensitive information. In some cases, an attacker might also install malware on the victim’s computer.
NXDOMAIN Attack
DNS servers are subject to a number of attacks, including the NXDOMAIN Attack on DNS Security. These attacks cause DNS servers to be unable to resolve the name of the domain they are attacking, and thus block access for all domain services. DNS servers can become overburdened with requests, and they may not have the resources to handle all the traffic.
Random Subdomain Attack
A Random Subdomain Attack is a method of disrupting DNS record lookups. Botnets are infected computers used by attackers to send malicious DNS requests. Domain Name System Security Extensions for DNS Servers (DNSSEC), are used to prevent this. DNSSEC digitally certifies data in order to protect its validity. This authentication process must occur at each level of the DNS lookup process, from the DNS root to the DNS client. DNSSEC works with SSL/TLS in order to strengthen the security and integrity of DNS records.
FAQ
What is a responsive design web design?
Responsive web design (RWD), is a way to create websites that display responsively on all devices, including smartphones, tablets, desktop computers, laptops and tablets. This allows visitors to view the website on one device and access other features like buttons, navigation menus, etc. The goal of RWD is to ensure that when a user views a site on any screen size, they view the exact version of the site.
For example, if you were building a website for a company whose products sell primarily through eCommerce, you would want to ensure that even if a customer viewed your website on a smartphone, they could easily purchase items from your store.
A responsive website will adapt its layout to suit the device it is being viewed on. A website that is viewed on your laptop will display the same way as a desktop website. It will be different if the page is viewed from your phone.
This means you can make a website that looks amazing on all types of devices.

It is a good idea for potential employers to receive your portfolio via email.
Market yourself as a freelancer. You can also advertise your services via job boards like Guru, Indeed, Guru, Upwork, and Freelance.
Freelancers are often assigned by recruiters posting job openings online. These recruiters are looking for qualified candidates to fill certain positions in specific industries.
These recruiters typically provide the candidate with a project brief outlining the position's requirements.
Freelancers are not required by law to sign any long-term agreements. However, if you plan to move forward, it is best to negotiate an upfront payment.
Many designers prefer to work directly with clients rather than through agencies. This may sound ideal but many people lack the skills.
Agency workers are often well-versed in the industry they work in. They have access the right training and resources to ensure they produce high-quality results.
Agency workers also receive higher hourly rates.
You won't be able to get in touch with your employer directly if you work with an agency.
Being a successful UI designer requires you to be self-motivated, creative.
Excellent communication skills are also required.
UI designers are responsible in designing websites through the creation of user interfaces (UI), as well visual elements.
They are also responsible in ensuring that the site meets all users' requirements.
This involves understanding the information users need and how to make your site work.
Wireframes can also be created by UI developers using a variety o tools. Before beginning to design, they use wireframing.
It is easy to create your own wireframes using the online templates.
Some designers concentrate on UI design only, while others mix UI design with graphics design.
Photoshop is a popular software used by graphic designers for editing images.
They then use Adobe InDesign to lay out pages and layouts.
Photographers capture images using digital cameras or DSLRs.
The photos are then uploaded to a photo editing software where text captions, filters and other effects can be added.
The photographer saves the image to a file compatible with the website.
It is vital to consider all aspects in the web design process.
This includes research, planning, wireframing, prototyping, testing, coding, content creation, and publishing.
Research – Before starting any new project, it is important to conduct extensive research.
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 are used to verify that the final product is consistent with the original vision.
Testing - It is important to test the prototype several times in order to make sure it works.
Coding - Coding is the act of writing computer code.
Content Creation – This covers everything from creating copy to managing social accounts.
Publishing means uploading files onto a server and making the site accessible.
You'll need to be able to understand the different projects you work on as a freelance UX/UI Designer.
For example, some companies only require wire frames, whereas others require full prototypes.
Depending upon the type and scope of the project, you may be asked for specific tasks.
For example, if you're hired to create wireframes, you might be expected to create several wireframes over time.
If you're hired to create a complete prototype, you may be required to develop a fully functional version of the site.
Strong interpersonal skills are important regardless of the project type.
Since most clients hire freelancers based on referrals, you must build solid relationships with potential employers.
You must also be able communicate clearly both verbally as well as in writing.
A portfolio is an important component of any freelancers' arsenal.
It showcases the quality of your work as well as your ability and willingness to provide high-quality results.
This is possible by creating an online portfolio.
