DNS security is like air traffic control for the internet. It manages the flow of data to ensure safe and correct routing, just like planes in crowded airspace.
Without DNS security, your domain and website are at risk from bad actors looking to manipulate the DNS process and misdirect visitors.
Whether it’s making your website unavailable to users as a result of a distributed denial of service (DDoS) attack or swapping your contact information for a domain hijacker’s own and transferring domain ownership — bad actors can seriously damage your website, revenue, and business reputation.
DNS issues can also interfere with your day-to-day website performance, site uptime, website speed, and reliability.
In short, DNS security is about fortifying your entire digital identity.
Identifying common types of DNS attacks
Knowledge is power. Let’s look at the major types of DNS cyberattacks and how to defend against them.
DNS cache poisoning (also known as DNS spoofing)
What happens:
The DNS stores the wrong IP address, and users are redirected to fake (often malicious) websites without realising it.
Possible outcomes:
Loss of credibility, loss of business, and customer data vulnerability.
Solutions:
Choose a domain provider that offers Domain Name System Security Extensions (DNSSEC), where digital signatures ensure that it hasn't been tampered with when the DNS translates a website name to an IP address.
Distributed denial of service (DDoS)
What happens:
A DDoS attack is when multiple systems flood a website’s bandwidth or resources, overwhelming the server and preventing genuine visits (denial of service).
Possible outcomes:
Website downtime, reputational damage, and financial loss.
Solutions:
Choose a domain provider that ensures its DNS infrastructure is resilient and that your hosting provider has robust DDoS protection for servers. Regularly monitor traffic and update network security systems.
DNS sinkhole attacks
What happens:
DNS entries are corrupted, access to specific sites or services is blocked, and traffic is routed to a potentially malicious destination.
Possible outcomes:
Exposure to sites hosting malicious software (malware), data theft, and disruption of services.
Solutions:Choose a domain provider that offers Domain Name System Security Extensions (DNSSEC), use DNS servers from reputable providers, and regularly update DNS servers. Learn about phishing and DNS attacks and how to protect your devices and information.
DNS amplification attacks
What happens:
Small queries are turned into much larger payloads directed at the victim’s network, resulting in high traffic levels.
Possible outcomes:
Network overload, potentially leading to a denial of service and resource drain.
Solutions:Make sure your provider monitors network traffic, regularly updates network security systems, and sets up DNS servers to answer requests only from known or internal IP addresses.
Domain hijacking
What happens:
An attacker gains unauthorised access to a website’s domain registration account, allowing them to alter registration details, redirect traffic, or take complete control of the domain.
Possible outcomes:
Loss of site control, reputational damage, redirection to malicious sites, and theft of sensitive information.
Solutions:
Enable two-factor authentication (2FA), choose unique, strong passwords, choose a reputable domain registrar, keep contact information updated, and educate domain registration account users about phishing scams.
Zone transfer attacks
What happens:
Attackers obtain a copy of the entire DNS zone file from the primary DNS server (which includes domain information, including DNS records) and copy it to a secondary DNS server. They can then target IP addresses of important services.
Possible outcomes:
Exposure of sensitive information, increased vulnerability, and potential subsequent attacks.
Solutions:
Restrict DNS zone transfers by allowing only authorised servers, implement access controls to prevent unauthorised zone transfers, and use DNSSEC.
Phishing
What happens:
By impersonating a trustworthy entity in an email or through messages, attackers deceive users into providing sensitive data such as passwords or credit card numbers on fake websites.
Possible outcomes:
Identity theft, financial loss, data breaches, and loss of organisational trust.
Solutions:
Learn about phishing tactics, use spam filters, and keep security software and systems updated.
Typosquatting
What happens:
By registering minor typographical errors of well-known domain names (like spcship.com instead of spaceship.com), unsuspecting users are led to fraudulent websites.
Possible outcomes:
Redirection to malicious sites, brand damage, information theft, and ad revenue theft.
Solutions:
Register common misspellings of your domain name, educate users to check domain names before entering sensitive information, and enforce policies to prevent the registration of domain names that closely resemble well-known brands or trade marks.
Registrar data breaches
What happens:
Attackers gain unauthorised access to domain registrar systems, and data breaches can reveal sensitive information like usernames, email addresses, passwords, and payment details.
Possible outcomes:
Personal data exposure, identity theft, financial fraud, and domain hijacking risks.
Solutions:
Registrars must maintain robust security practices to protect customer data, and users must choose strong, unique passwords and use 2FA.
DNS tunnelling
What happens:
Using the DNS protocol, attackers can smuggle unauthorised data through a network, bypassing typical network security measures.
Possible outcomes:
Malware communication, data exfiltration, network security compromise, and bandwidth consumption.
Solutions:
Registrars must monitor DNS traffic for signs of DNS tunnelling, enforce restrictive DNS policies, and configure firewalls to look for unusual patterns.
Cache poisoning through malware
What happens:
Malware is used to corrupt the DNS cache of a user’s computer or network device, resulting in domain names resolving to incorrect IP addresses. Instead of the expected destination, users are redirected to a fraudulent or malicious site.
Possible outcomes:
Redirection, data theft, spread of malware, and loss of trust.
Solutions:
Registrars can collaborate with internet service providers (ISPs) and security organisations to identify and block malicious domains used by malware. Use anti-malware software and upgrade all software regularly.
DNS-related attacks on domain provider platforms
What happens:
A service provider's DNS infrastructure is targeted, with the intention of disrupting the provider’s platform and operations. Attacks may include DDoS attacks on DNS servers, DNS hijacking, and cache poisoning.
Possible outcomes:
Service disruption, data breach risk, reputational damage, and operational and financial losses.
Solutions:
Registrars must have high-security protocols and practices. Robust monitoring and incident response capabilities can help detect and respond to DNS security incidents promptly. Choose a provider with a strong reputation for security and trustworthiness.
Helping to protect your domain from attacks
Now you know more about DNS security attacks and why DNS security is important, here are two ways your chosen domain registrar can help keep your domain safe.
Zone file integrity
What happens:
Zone file integrity refers to maintaining the accuracy and security of the DNS zone file. A compromise in zone file integrity can occur due to unauthorised access, misconfigurations, or attacks, and can lead to users being redirected to incorrect IP addresses.
Possible outcomes:
Misdirection to unintended or malicious websites, damage to domain reputation, disruption to email delivery records due to MX record tampering, and the potential for further attacks.
Solutions:
Registrars must regularly audit DNS zone files for unauthorised changes or inaccuracies, implement DNSSEC, maintain backup and recovery plans, and limit access to DNS record modification.
DNS abuse reporting
What happens:
DNS abuse reporting is where users, IT professionals, or automated systems proactively flag DNS activity or misuse to organisations responsible for handling such issues.
Possible outcomes:
Without reporting, malicious activities can continue, compromising network security and spreading malware and phishing campaigns.
Solutions:
Education on reporting protocols, collaboration with DNS authorities, automated detection, and prompt response and action can help DNS abuse reporting succeed.
