Secure your DNS, Protect your network
DNS is mission-critical to access apps dynamically, if the DNS server experiences an outage, a firm can’t access any vital app or services. DNS data and servers have become paramount targets and entry points for data espionage. Businesses are making enterprise network security a major priority, they experienced DNS assaults and suffered irreparable losses such as huge business losses, application outages, and data theft. Traditional network security solutions have become unsuccessful when focusing on DNS protection. They are ineffective in response to copious DNS attacks, and are incapable of identifying DNS tunneling or attempts at data exfiltration.
DNS attacks are shifting from actual brute-force attacks to more intricated attacks within the internal network. It forces enterprises to employ smart mitigation solutions to easily cope with evolving threats. To manage DNS security, enterprises must inspect DNS traffic departing from their network and ensure access limits and proper hygiene for DNS-related accounts in order to remain vigilant, plug security holes, and patrol for potential breaches around the clock.

Types of DNS Security Threats
With the continually changing structure of the digital ecosystem, DNS security risks are also getting more sophisticated and challenging to detect. Here're some DNS security risks that DNS servers are susceptible to:
Typo squatting
Typo squatting is a method of registering a domain name that is extremely similar to an already-existing domain or a well-known brand. This is viewed as a security problem since it poses a serious threat to company confidentiality. Cybercriminals may use typosquatting as a means of information theft. Information about freshly registered domain registrations can easily be obtained, it is possible to register a domain that is quite close to a well-known brand or domain and nearly duplicate it for harmful intentions.
Distributed Denial of Service Attacks (DDoS)
Despite not being specifically malicious, distributed denial of service (DDoS) attacks hinder access to the website server. DDoS is a logical traffic bottleneck for websites and frequently occurs when businesses overlook their network’s capacity planning. For the servers to function successfully, the quantity of incoming requests must be carefully considered. Employing a DNS provider is crucial here to combating such threats.
DNS Cache Poisoning
A certain amount of data is cached on the server whenever a user accesses the internet. By lessening the burden on the DNS, caching primarily aims to improve internet performance. When a malicious website or domain is cached on the server, cache poisoning occurs.
DNS Amplification
DNS servers are frequently set up insecurely or with recursive configuration. The domain resolution process (converting the text information input to a machine language) is made more reliable by the DNS recursion scheme. Although the goal of DNS amplification is to secure DNS, open recursive DNS servers are more vulnerable to cyberattacks and can be used to intensify DDoS attacks.
Domain Hijacking
Domain hijacking involves altering DNS servers and domain registrar configuration to manage direct traffic away from the original servers and to new locations. When attackers have hijacked the domain name, they will use it to launch malicious operations like setting up a counterfeit page for payment processors like PayPal, Visa, or banking systems. Attackers will create an exact replica of the legitimate website reading sensitive personal data including email addresses, usernames, and passwords.
DNS Tunnelling
Organizations permit DNS traffic to freely access and exit their networks as it is a trustworthy protocol. Cybercriminals exploit DNS for data exfiltration by using malware whose DNS requests contain data being exfiltrated. As the target DNS server is controlled by the website’s owner, the attackers make certain that data reaches a server where attackers can process it and send a response to the DNS response packet.
Best Practices for DNS Security
DNS Security Extensions or DNSSEC
Implementing DNSSEC is recommendable to validate DNS information. DNCCEC employs public-key cryptography to verify the process. The root domain is validated using certificate-based authentication. An effective DNSSEC system confirms that the DNS server responding to a request is legitimate.
Data Encryption
The data provided in DNS requests and responses can be encrypted to provide the server with an additional layer of protection. Data encryption adds an extra degree of security by preventing hackers from stealing the data for malicious use. If the information is intercepted, even if it is encrypted, it cannot be replicated or used maliciously.
Deploying Secure DNS Configurations
DNS servers can be operated independently within an organization. It keeps DNS servers isolated and prevents relationships between them. Consequently, if one server is compromised, the effect will be limited and won't spread to the wider ecosystem. Secure DNS configuration can also restrict the amount of data each server stores to prevent the compromise of a larger collection of data.
Conducting System Updates Steadily
DNS servers follow a cadence for routine changes. It is crucial to regularly run these updates. Noval security protocols included in these upgrades allow the servers to identify any vulnerabilities and patch them before they affect the larger ecosystem.
Strengthening Detection Protocols
A strong detection protocol is critical to monitor and prevent malware attacks beforehand, for instance, increasing DNS activity from one source and about a particular domain. When attackers attempt to gain access to the DNS server for spoofing, there is an increase in malicious activities from one source with multiple domain names.
Security Training
IT security training is mandatory to ensure robust security maintenance for DNS servers. When users understand potential risks, they can use safe practices while accessing the internet. For example, verifying security certificates for websites they access, avoiding clicking unrecognized links, and performing security checks when required.

DNS Security Services - FAQs
-
What is DNS security?
-
The Domain Name System (DNS) security is the technique of defending DNS infrastructure from cyberattacks to support it operating fast and reliably. Establishing redundant DNS servers, using security technologies like DNSSEC, and mandating stringent DNS logging are all components of a good DNS security plan.
-
Why is DNS security important?
-
The DNS system has a number of architectural flaws. Due to these restrictions and technological advancements, DNS servers are susceptible to a variety of attacks, such as spoofing, amplification, DoS or the collection of sensitive personal data. Additionally, because DNS is a necessary component of the majority of Internet queries, it may be a target for attacks.
-
What is DNSSEC?
-
DNSSEC is the suite of extensions to the DNS standard. It uses digital signatures to authenticate the DNS responses. Several attacks like DNS spoofing, cache poisoning, and man-in-the-middle attacks etc. are prevented by DNSSEC from injecting incorrect information into DNS resolvers.
When DNSSEC is enabled, resolvers scan the DNS record provided by authoritative DNS servers for a legitimate digital signature. This signature cannot be faked by attackers, preventing users from being misdirected to harmful websites.
-
What is a DNS firewall?
-
A DNS firewall offers DNS servers several security and performance benefits. It sits between the user’s recursive resolver and the authoritative nameserver of the website or service. To stop attackers from overwhelming the server, the firewall offers rate-limiting services.
The DNS firewall can maintain the operator's website or service if the server goes offline due to an attack or for any other reason by providing DNS responses from cache. A DNS firewall can offer speed improvements like quicker DNS lookups and lower bandwidth costs for the DNS operator to its security capabilities.
-
Explaining DNS as a security tool
-
DNS resolvers offer security solutions to their end users who are browsing the Internet. Certain DNS resolvers offer capabilities such as content filtering preventing access to websites known to host malware and spam, and botnet prevention blocking contact with recognized botnets. A user can switch to one of these recursive DNS services by altering a single setting on their local router.
