DNS security has been an ongoing problem for the Internet over 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 Records are used for DNS security. They can be added to domains. SRV record are usually provided and maintained by the host. These records often include the name of the service and the priority number. Higher priority records will be reviewed sooner than lower priority records.
DNSSEC
DNSSEC is a system for DNS security. It requires DNS servers signing their queries. This ensures that the identity of an application does not change based on a change in the DNS server's identity. DNSSEC may be used on both mobile devices and servers.
DNS Tunnelling
DNS tunnelling utilities attempt to put as much information as possible in the requests and responses. The requests and replies tend to have lengthy labels and general names. This can indicate a malicious domain.
DNS Hijacking
DNS hijacking refers to cybercrime where an attacker intercepts a DNS query and redirects it towards 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. While it looks legitimate, the spoof website collects sensitive information. In some cases, an attacker might also install malware on the victim’s computer.
NXDOMAIN Attack
DNS servers are vulnerable to numerous attacks, such as the NXDOMAIN Attack upon 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. 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. To send malicious DNS queries, the attackers use botnets that are made up of infected computers. Domain Name System Security Extensions are used by DNS servers 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 is used together with SSL/TLS for stronger security of DNS records.
