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 cannot verify the authenticity of a reply packet. Recursive resolvers are limited to checking if the response comes from the same IP address. This weak authentication mechanism means that forgers can easily forge responses, leaving resolvers unable to detect them.
SRV records
Domain names can have SRV records added to them. These records are used to secure DNS. SRV Records are usually provided by hosts. They are often associated with the name of the service that is provided and the priority number. Lower priority records are looked at earlier than higher priority records.
DNSSEC
DNSSEC is an authentication mechanism that requires DNS servers in order to sign responses to queries. This ensures that the identity of an application does not change based on a change in the DNS server's identity. DNSSEC can also be deployed on mobile devices or servers.
DNS Tunnelling
DNS tunnelling utilities aim to provide as much information as possible within the responses and requests. Requests and responses are often given long labels and names. This can indicate that the domain is malicious.
DNS Hijacking
DNS hijacking refers to cybercrime where an attacker intercepts a DNS query and redirects it towards 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. The spoof site looks like a legitimate site but collects sensitive information. In some cases the attacker may also install malware to the victim's system.
NXDOMAIN Attack
DNS servers are vulnerable to numerous attacks, such as the NXDOMAIN Attack upon DNS Security. These attacks are designed to disrupt DNS name resolution and prevent access to any services that fall under the domain. DNS servers can become overwhelmed with requests and may not be able handle all traffic.
Random Subdomain Attack
A Random Subdomain Attack is a method of disrupting DNS record lookups. The attackers use botnets of infected computers to send malicious DNS queries. Domain Name System Security Extensions are used by DNS servers to prevent this. DNSSEC digitally signs data for validity. This authentication must take effect at all levels of DNS lookup, from the DNS root down to the DNS client. DNSSEC works in conjunction with SSL/TLS to make the security of DNS records more robust.

What is a responsive design web design?
Responsive Web Design, also known as RWD, is a way of designing websites so that content displays on all devices. This includes desktop computers, tablets (tablets), smartphones, etc. This allows users the ability to view a website simultaneously on different devices and still have access to other features like navigation menus, buttons, and so forth.
