Applying DNS Protection

Applying DNS protection is a vital part of internet security as it manages all attempted hackign attempts aimed at your IP addresses, the system that is used by a lot of Internet applications. Thus, any lapse in DNS security might have considerable consequences if a cybercriminal accesses a vulnerable DNS server.

With all the developments in remote working using 5G technology, a lot of the security world focus continues to be on preventing strikes and endpoint security against IoT networks.It has been reported that 45%of company data nowadays resides on endpoint systems, that almost 80% of employees use multiple unit to get into this information, and that cybercriminals are equipped to hack IoT equipment and infiltrate company networks to be able to look for insecure management level accounts.

Nevertheless, while securing endpoints as well as IoT networks is undoubtedly necessary, it is equally vital not to ignore DNS security. The web runs on DNS; and while many individuals realize the connection between web browsers and IP addresses, few recognize that DNS also plays a crucial part in how apps speak to one another. So, in case a DNS server is not fully secured, several kinds of security issues could occur.

While there are lots of diverse labels for DNS protection problems, they usually fall into two separate groups – ones that redirect services, apps, and users to an alternative location (DNS spoofing, DNS hijacking, etc.), along with those that overwhelm sites with DNS reply visitors (DNS amplification strikes, DNS DDoS attacks, etc.). Additionally, attackers are able to exploit unsecured DNS servers to bypass community security settings (DNS tunneling) or maybe launch Phantom Domain Attacks.

In 2020, IDC conducted a survey of 900 businesses to look at the scale of DNS attacks as well to gauge what actions businesses have been applying to mitigate DNS protection issues. 79% of respondents noted having encountered a single or even more DNS based attacks in the previous 12 weeks, with the most witnesses DNS protection challenges being:

  • DNS spoofing (39%)
  • DNS-based malware (34%)
  • DDoS attack (27%)
  • DNS amplification (21%)
  • Genuine requests being labeled as a threat/false positives (19%)
  • DNS tunneling (17%)

Although it could be the case that respondents had already implemented steps to mitigate DNS security consequences, the effects of the episodes included downtime, compromised sites, brand damage and the theft of very sensitive info. IDC calculated the typical price of each successful DNS attack at around $924,000.

Thoug 98% of respondents to the IDC survey claimed they had a number of processes for DNS security in place, many users had measures which alerted them retrospectively to a compromised DNS server, rather compared to proactive steps to stop DNS attacks achieving success in the very first place.

To proactively stop DNS attacks, security professionals suggest three DNS security best practices:

DNS Security Extensions (DNSSEC): DNS protection extensions use electronic signature main pairs to verify if the solution to a DNS query is originating from the correct source.

DNS above TLS: DNS above TLS encrypts basic text queries to avoid man-in-the-middle attacks as well as attackers tracking what websites a certain program or user visits.

DNS over HTTPS: DNS above HTTPS is a substitute to DNS above TLS – the real difference actually being that encrypted DNS queries as well as responses are camouflaged inside various other HTTPS visitors.

These DNS security very best practices solve the problems of Website Servers lacking encryption or authentication, and also add to a multilayered, zero trust strategy to DNS security. While it’s nonetheless recommended for organizations to feed DNS information into SIEMs for checking, evaluation, and also alerting, by using two of the three DNS protection best methods the quantity of DNS protection problem alerts must decrease significantly.
