What you Need to Know about DNS Security

By Bill Rollins 30 June, 2023 2 mins read

DNS security has become an issue that has plagued the Internet for many years. 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 allows forgers to easily forge replies, making it difficult for resolvers to detect them.

SRV Records

SRV files are used to protect DNS domain names. SRV records are typically provided by the host. These records are usually associated with the service name and 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 makes sure that an application's identity does not change due to a DNS server's identity changing. DNSSEC may be used on both mobile devices and servers.

DNS Tunnelling

DNS tunnelling utilities seek to give as much information and possible responses as possible. This is why the responses and requests tend to be long and have large names. This can indicate that the domain is malicious.

DNS Hijacking

DNS hijacking, a form cybercrime, is when an attacker intercepts DNS requests and redirects them to malicious DNS servers. This malicious DNS server then returns the wrong IP address, which the attacker uses to redirect the user to a fake website. Although it appears to be a legitimate website, the spoof site collects sensitive information. In some cases, the attacker may also install malware on the victim's computer.

NXDOMAIN Attack

DNS servers can be attacked by a variety of methods, including the NXDOMAIN Attack On DNS Security. These attacks disrupt the name resolution of the domain and block access to all services. Overburdened DNS servers may become overwhelmed by requests and not be able to handle all of the traffic.

Random Subdomain Attack

Random Subdomain Attacks are used to interrupt DNS record lookups. Botnets are infected computers used by attackers to send malicious DNS requests. To prevent this, DNS servers use Domain Name System Security Extensions (DNSSEC). DNSSEC digitally signs data for validity. This authentication must occur at all levels in the DNS lookup process, starting from the DNS root and ending with the DNS client. DNSSEC works in conjunction with SSL/TLS to make the security of DNS records more robust.

Static websites are becoming more popular due to their ease of maintenance. They're easier to update and maintain when compared to a fully-featured website with many different components (such as blogs).

They load much faster than dynamic counterparts. They are ideal for mobile users and those with slow Internet connections.
