NCSC Releases Fact Sheet on DNS Monitoring
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.
