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 fact
sheet on DNS monitoring for additional information and recommendations.
