DNS security has become an issue that has plagued the Internet for many years. DNS's basic design relied on recursive address resolvers to resolve IP addresses. Security was not considered a primary concern. DNS does not verify the authenticity of a response packet; recursive resolvers can only check if it appears to come 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 record are usually provided and maintained by the host. They often have the priority number and the name of service. Lower priority records are more frequently reviewed 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 is available for both mobile and server devices.
DNS Tunnelling
DNS tunnelling utilities attempt to put as much information as possible in the requests and responses. Therefore, requests and responses often have long labels or overall names. This can be an indicator of 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. This malicious DNS server will then return the wrong IP address. The attacker uses this to redirect the user on to a fake web page. The spoof site looks like a legitimate site but collects sensitive information. Sometimes, malware may be installed on victim's computers by the attacker.
NXDOMAIN Attack
DNS servers are subject to a number of attacks, including the NXDOMAIN Attack on DNS Security. These attacks affect DNS servers by disrupting the name resolution for the domain, effectively blocking access from all services under that domain. DNS servers can become overburdened with requests, and they may not have the resources to handle all the traffic.
Random Subdomain Attack
Random Subdomain Attacks can be used to disrupt DNS records lookups. Botnets of infected computers are used by the attackers to send malicious DNS queries. Domain Name System Security Extensions can be used by DNS servers (DNSSEC). DNSSEC digitally signs data to ensure its validity. This authentication must be done at every level of the DNS lookup process from the DNS root up to the DNS client. DNSSEC is used together with SSL/TLS for stronger security of DNS records.
