Protective DNS: Why Telcos Are Turning to DNS as the Platform for Consumer Security
For years, internet service providers have offered a range of consumer security services. These have typically focused on the endpoint and the home: secure residential gateways, parental controls and bundled antivirus or identity protection services. What they have not historically done is treat the network itself as the primary enforcement point for security. That is […]

Hiding in Plain Sight: Abusing Composite Domain Names
Abstract Many DNS-based services utilize composite queries, which are queries formed by embedding a referenced domain as a subdomain. For example, example-com.translate.goog refers to example.com as the source domain. The use of composite queries allows services to route users effectively on the Internet; however, these services can also present a security challenge by enabling actors […]

What You Cannot See is Hurting You Most
I was on a call last week with a vice president of IT operations who confidently told me their infrastructure visibility was “probably 85 percent, maybe 90 percent.” When I asked how they measured that, there was a pause. “Well, we run network scans weekly, we have got endpoint agents on most systems and our […]

Unified Asset Visibility: A Strategic Imperative for CIOs and CISOs
On Monday morning, the CIO sees one picture of the environment in the cloud console, another in the configuration management database (CMDB) dashboard and a third in a capacity-planning spreadsheet. An hour later, the CISO joins a security review with yet another set of “authoritative” numbers coming from endpoint detection and response (EDR) systems, security […]

Infoblox Partners with Leading SASE Vendors to Modernize DNS and DHCP for Distributed Enterprises
Ecosystem partnerships promise to bring cloud-based DDI to branch networks and introduce an Early Access Program for select customers. User experience determines the success of secure access service edge (SASE) programs, yet DNS and DHCP often go unnoticed until failures occur. These issues can appear as application outages, software-as-a-service (SaaS) slowdowns or site-specific problems that […]
