NCSC Releases Fact Sheet on DNS Monitoring

release date: October 4, 2019

The Dutch National Cyber Security Centre (NCSC) has released a fact sheet on
the increasing difficulty of Domain Name System (DNS) monitoring. NCSC warns
that although modernization of transport protocols is helpful, it also makes it
more difficult to monitor or modify DNS requests. These changes could render an
organization’s security controls ineffective.

The Cybersecurity and Infrastructure Security Agency (CISA) recommends users
and administrators review the Dutch NCSC
sheet on DNS monitoring
for additional information and recommendations.
