Risk Perspectives of DNS Endpoint Activities
DNS endpoint activity plays a pivotal role in an organization’s cybersecurity posture. As the starting point
of nearly all network communications, DNS queries can also serve as a gateway for attackers to infiltrate
systems. Abnormal or seemingly benign DNS behavior at the endpoint level may indicate serious threats
such as data exfiltration (e.g., DNS tunneling), malicious command-and-control (C2) communication, or
access to harmful domains.
Proactively monitoring and analyzing DNS endpoint activity enables organizations to detect and mitigate
threats early—before they escalate into damaging incidents.
Impact of Unknown Risks in DNS Activities
Attackers are becoming increasingly adept at exploiting legitimate DNS mechanisms to conceal malicious activities. While many DNS requests may appear normal on the surface, they can in fact be used to control endpoints or exfiltrate sensitive data.
These “unknown risks” often bypass traditional security tools, making incidents difficult to contain once detected. To mitigate this, organizations must establish full visibility and interpretability of DNS activity, enabling faster threat detection and response before damage is done.
Endpoint DNS activity offers more than just domain resolution logs—it provides critical data that reflects user behavior, application operations,
and potential malicious activity. By deeply analyzing DNS traffic, organizations can:
Detect abnormal communication patterns (e.g., rare domain requests or high volumes of failed connections)
Establish behavioral baselines for devices and users
Identify access to high-risk or suspicious domains
Uncover undefined or previously unknown indicators of compromise (IOCs)
These insights form the foundation for building an organization’s own threat intelligence capabilities.
Why Self-Organized Security Intelligence
is Superior to Cross-Industry Common Intelligence?
While cross-industry threat intelligence sharing offers valuable high-level insights, every organization operates within a unique network environment, with distinct usage patterns and business processes.
By analyzing and correlating their own DNS activity, organizations can develop internal threat intelligence that more accurately reflects their specific risk landscape. For instance, certain domains that appear harmless to others may, within a particular industry or operational context, be tied to sensitive data exchanges, supply chain communications, or proprietary applications. Only through self-driven analysis can such context-specific significance be fully understood.
Advantages and Necessity of Governing
Self-Organized Security Intelligence
Establishing an internal threat intelligence governance capability is not only a strategic move to enhance cybersecurity defenses—it is also an essential foundation for future-ready threat management. Key benefits include:
- Timely and actionable risk insights: Intelligence derived from an organization’s own environment offers greater relevance and immediacy for decision-making.
- Reduced dependence on external threat feeds: By identifying and understanding its own core risks, the organization minimizes the risk of delayed or inaccurate threat information.
- Improved incident response efficiency: Enables faster threat attribution and targeted mitigation at the endpoint level.
- Informed security policy development: Empowers more accurate and evidence-based security governance and policy refinement.
In summary, by leveraging DNS endpoint activity, organizations can develop proprietary threat intelligence and risk insights—transforming their security strategy from purely reactive to proactively governed, context-aware, and intelligence-driven.
Comprehensive DNS Security, Threat Hunting,
and Intelligence-Driven Defense Solutions
Our SENTRY series product is equipped with core system capabilities including DNS security defense, threat hunting, and service performance optimization—empowering organizations to effectively counter known DNS-based threats. Beyond its foundational features, SENTRY offers advanced cybersecurity service modules—most notably, ScoutEye, which is specifically designed to support Risk Behavior Analysis and Threat Intelligence Governance.
ScoutEye is designed to provide organizations with complete visibility into the behavior of all network-connected devices, enabling the analysis of key risk indicators and the retention of detailed activity logs. At the same time, it facilitates the development of environment-specific threat intelligence, empowering organizations to detect and respond to emerging risks before they evolve into actual threats—supporting smarter, more proactive cybersecurity strategies.
ScoutEye – Behavior Risk Assessment & Threat Insight
ScoutEye channels all DNS activity into its proprietary analytical engine, where
multiple critical risk factors are correlated to evaluate the risk level of each event.
This significantly reduces the time, manpower, and cost typically required for
security teams to manually process vast amounts of data.
By focusing directly on high-risk behaviors and their associated DNS interactions,
ScoutEye shifts security operations from a reactive,compliance-driven approach to a
proactive, risk-driven defense strategy.
What critical risk factors that ScoutEye top-on:
- Connections to high-risk top-level domains (TLDs)
- Access to rare or newly registered risky domains
- Behavioral patterns indicative of DNS tunneling
- Correlation between DNS queries and known malicious IPs or domains
- Abnormally high DNS query failure rates from specific devices
- Access patterns involving public cloud services
