DNS Protection

In order to best tackle the threat posed by malware attacks trying to infiltrate your business networks you need to configure DNS malware.

In doing so you will be adding a tool that places an additional level of protection between a user and the web to stop the accessing of websites that have previously been leveraged to kick off spam campaigns attacks. It works as on each occasion that a page request is sent to a browser, a DNS lookup is completed to ascertain the unique IP address to find the website that the web user is asking to view. The IP address is then checked to and, if safe, will be displayed to the web user. This is a very quick process that takes less than one second to complete.

Cybercriminals sometimes target DNS servers in an attempt to send those using the Internet to their malicious websites -DNS hijacking. Along with this they may try to hijack control of the web portal by conducting DNS response traffic in Denial of Service campaigns.

Attacks such as these show why businesses need to use DNS malware protection services in order to keep the network safe. Most cybersecurity specialists recommend the addition of DNS security extensions which use digital signature key pairs to authenticate DNS queries and make sure that they are being sent from someone genuine. DNS over TLS encrypts plain text queries to prevent them from being captured and amended some way or another. DNS over HTTPS is similar to DNS over TLS as encryption is used and replies are hidden internally in other HTTPS traffic. A SIEM system and to share DNS data into the SIEM for additional monitoring and reviewing.

These activities are completed at the point that the DNS lookup is requested for a particular web site. The DNS does not spot the difference between genuine websites and malicious spam-laden web pages. However, as all websites have an IP address, and the DNS will share those addresses without question, DNS malware protection can review these IP addresses up to blacklists of recognized websites that have been linked with cyber attacks to ascertain if they are safe to use. If an IP address is malicious and blacklisted the request to load it or view it will be denied. A locally-hosted webpage will be served to inform the web user of this.

Why You Should Use DNS Protection Measures

DNS protection is the best system because:

  • Filtering takes place before content is displayed on a browser so there is no effect on internet bandwidth. There is more or less no latency registered.
  • Software installations are not necessary, saving any additional spending to bring servers up to speed with modern technology.
  • Quick and easy configuration process which involves pointing your DNS to the service provider’s DNS servers. The DNS servers used by vendors should be faster than those provided by your ISP.

Along with givingIn addition to protecting your DNS processes from malware, DNS malware protection measures will prevent attacks from known sources attempting to phish for log-in credentials and allow groups to manage the range of content that can be seen by staff members.
