Unlocking Defense-in-Depth: A Protection That Exceeds Conventional Methods

DNS is mission-critical for dynamic app access; if the DNS server goes down, a company cannot access any key applications or services. DNS data and servers have become prime targets for data espionage and access points. Businesses are making corporate network security a top concern, since many have suffered catastrophic losses due to DNS attacks, including massive commercial losses, application disruptions, and data theft. Traditional network security solutions have failed while concentrating on DNS protection. They are inefficient against several DNS attacks and unable to recognise DNS tunnelling or data exfiltration efforts.

DNS assaults are changing from brute-force attempts to more sophisticated internal network attacks. It necessitates the use of intelligent mitigation solutions by businesses in order to efficiently deal with shifting dangers. To manage DNS security, companies must check DNS traffic leaving their network and maintain access limitations and adequate hygiene for DNS-related accounts in order to stay attentive, repair security gaps, and patrol for possible breaches 24 hours a day.

Threats to DNS Security, Classified

With the ever-changing structure of the digital ecosystem, DNS security threats are becoming more complex and difficult to detect. DNS servers are vulnerable to the following security risks:

Typo squatting

Typo squatting is the practise of registering a domain name that is almost identical to an existing domain or a well-known brand. This is considered a security issue since it presents a significant risk to corporate confidentiality. Cybercriminals may employ typosquatting to steal sensitive data. It is feasible to register a domain that closely resembles a well-known brand or domain for malicious purposes since it is simple to gather information about newly registered domains.

DDoS Attacks, or Distributed Denial of Service (DDoS)

Although not always malevolent, distributed denial of service (DDoS) assaults impede website server access. DDoS is a logical traffic bottleneck for websites, and it happens regularly when firms fail to prepare for network capacity. The number of incoming requests must be carefully examined for the servers to operate well. Employing a DNS provider is essential for defending against such attacks.

Amplification of DNS

Frequently, DNS servers are configured insecurely or with recursive setup. The DNS recursion strategy increases the reliability of the domain resolution process (turning text information into machine language). While the purpose of DNS amplification is to safeguard DNS, open recursive DNS servers are more susceptible to assaults and may be used to amplify DDoS attacks.

DNS Cache Pollution

Whenever a user visits the internet, a certain amount of data is cached on the server. Caching's primary goal is to increase internet speed by reducing the load on the DNS. Cache poisoning happens when a malicious webpage or domain is cached on the server.

DNS Tunnelling

As a trustworthy protocol, organisations allows DNS traffic to freely enter and depart their networks. Cybercriminals use DNS to exfiltrate data by using malware whose DNS queries include the data to be exfiltrated. As the target DNS server is under the control of the website's owner, the attackers ensure that data is sent to a server where they may analyse it and send a response to the DNS response packet.

Domain Hijacking

Domain hijacking is reconfiguring DNS servers and domain registrars to reroute traffic away from the original servers and to new ones. When attackers hijack a domain name, they utilise it to undertake fraudulent actions, such as establishing a fake website for payment processors such as PayPal, Visa, or banking systems. The attackers will develop an identical clone of the real website in order to steal sensitive information, such as email addresses, usernames, and passwords.

Best Security Practices for DNS

DNSSEC or DNS Security Extensions

Implementing DNSSEC to verify DNS information is recommended. To validate the procedure, DNCCEC uses public-key cryptography. Using certificate-based authentication, the root domain is verified. An efficient DNSSEC system verifies the legitimacy of the DNS server replying to a request.

Data Encryption

The data sent in DNS queries and answers may be encrypted to offer an extra degree of security to the server. Encrypting data increases security by preventing hackers from taking it for nefarious purposes. Even if the information is intercepted, it cannot be duplicated or used maliciously if it is encrypted.

Implementing Safe DNS Configurations

DNS servers may be separately administered inside an organisation. It stops DNS servers from interacting with one another and isolates them. As a result, if a single server is hacked, the impact will be restricted and will not affect the whole ecosystem. In order to avoid the compromise of a bigger collection of data, secure DNS settings may also limit the quantity of data each server maintains.

Continuously Conducting System Updates

DNS servers adhere to a schedule for regular modifications. It is essential to execute these updates periodically. Incorporating novel security protocols, these updates enable servers to discover and repair flaws before they impact the whole ecosystem.

Security Instruction

Training in IT security is needed to guarantee effective DNS server security maintenance. When consumers are aware of possible threats, they are able to browse the internet safely. For example, confirming website security certifications, avoiding clicking on unknown links, and executing security checks as necessary.

Improving Detection Protocols

A robust detection mechanism is essential for monitoring and preventing malware assaults in advance, such as an increase in DNS activity from a single source pertaining to a certain domain. When attackers try to access the DNS server for spoofing, malicious activity from a single source with several domain names increases.

DNS Security Services – FAQs

The Domain Name System (DNS) security is the method of protecting DNS infrastructure against cyberattacks to ensure its rapid and dependable operation. A solid DNS security strategy includes establishing redundant DNS servers, using security technologies such as DNSSEC, and demanding tight DNS logging.
There are a number of architectural problems in the DNS system. Due to these limits and technical improvements, DNS servers are vulnerable to several attacks, including spoofing, amplification, DoS, and the acquisition of sensitive personal data. In addition, since DNS is required for the vast majority of Internet searches, it may be a target of assaults.
DNSSEC is the set of DNS standard extensions. It employs digital signatures to verify DNS answers. DNSSEC prevents certain attacks, such as DNS spoofing, cache poisoning, and man-in-the-middle attacks, from introducing false information into DNS resolvers.

When DNSSEC is enabled, resolvers examine authoritative DNS servers' DNS records for a valid digital signature. This signature is unforgeable, protecting visitors from being diverted to malicious websites.
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.
DNS resolvers provide their Internet-browsing end consumers with security solutions. Certain DNS resolvers include features such as content filtering, which prevents access to websites known to house malware and spam, and botnet prevention, which prevents communication with known botnets. A user may switch to one of these recursive DNS providers by a single router configuration change.
