Looking for ways to protect your business against the latest cybersecurity threats? Fast flux DNS attacks are making headlines, but NSA-recommended protective DNS measures can shield your network. Keep reading to learn how Capstone has implemented these security measures ahead of federal recommendations.
Fast Flux Protection: How Capstone Beats NSA Security Recommendations
In March 2025, the National Security Agency (NSA) and Cybersecurity and Infrastructure Security Agency (CISA) published updated guidance on protective DNS security. Their recommendations highlight what Capstone Technologies Group clients already know – DNS protection is fundamental to effective cybersecurity, especially against emerging threats like fast flux attacks.

What Are Fast Flux Attacks?
- What They Are: An evasion technique cybercriminals use to hide malicious websites behind rapidly changing IP addresses.
- Why They're Dangerous:
- Like a shell game that keeps moving the target, these attacks are designed to bypass traditional security measures.
- Recent headlines have highlighted several major breaches where fast flux techniques were used to evade detection.
- How We Protect You: Our protective DNS implementation specifically counters this threat by:
- Analyzing DNS patterns to identify suspicious behavior
- Checking domains against real-time threat intelligence
- Monitoring for abnormal DNS record changes
- Blocking access to domains showing fast flux characteristics
Example/Use Case: A healthcare organization might face attackers using fast flux techniques to hide malicious domains that attempt to steal patient records. With our Protective DNS implementation, these attempts are identified and blocked before they can reach your network.
Federal Recommendations vs. Capstone's Implementation
The NSA and CISA now recommend several protective DNS features that security-conscious organizations should implement:
- Block malicious domains ✓ Implemented for all Capstone clients
- Phishing protection ✓ Built into our standard security package
- Fast flux attack defense ✓ Actively protecting against this emerging threat
- DNS over TLS encryption ✓ Added at no cost to enhance security
- Detailed DNS logging/monitoring ✓ Providing visibility into potential threats
Example/Use Case: An accounting firm in Dublin can rest easy knowing that their network security is ahead of federal recommendations, protecting sensitive financial data from sophisticated attacks before they become widespread.
The Election Security Connection
- What Sets Us Apart: Our proven security expertise at the highest levels of infrastructure protection.
- Our Role:
- Capstone Technologies Group played a key role in the 2018 Ohio Election Audit in Clark County.
- We implemented comprehensive cybersecurity assessments based on an 88-point security checklist.
- How It Benefits You:
- The methodologies we applied to election security are the same ones now protecting your business.
- When you need security expertise you can trust, our experience securing democracy's infrastructure speaks volumes.
Example/Use Case: A law firm in Beavercreek benefits from the same rigorous security practices that protected Ohio's election systems, ensuring client confidentiality remains intact against sophisticated threats.
Why DNS Security Matters
- The Internet's Address Book: The DNS (Domain Name System) translates human-readable website names into machine-readable IP addresses.
- Your First Line of Defense:
- When properly secured, DNS becomes your first line of defense against various cyber threats.
- Prevents connections to known malicious sites
- Blocks command and control communications
- Stops data exfiltration attempts
- The Statistics:
- Up to 79% of cyberattacks can be prevented by properly securing the DNS layer.
- This fundamental protection is why federal agencies now recommend what Capstone has long provided.
Example/Use Case: A marketing agency in Grandview with multiple remote employees can protect their creative assets by implementing protective DNS that shields workers regardless of their location.
How Our Protective DNS Implementation Works
- Advanced Filtering: Every DNS query your network makes passes through sophisticated filtering.
- Real-Time Protection:
- Analyzes every website request before connection is established
- Checks against continuously updated threat intelligence
- Blocks malicious connections before they form
- Beyond Basic Security:
- Encrypted DNS over TLS prevents eavesdropping on your browsing activity
- Machine learning identifies new threats based on behavior patterns
- Comprehensive logging provides visibility and aids in security investigations
Example/Use Case: A healthcare office in Springfield can protect patient data by ensuring that staff computers can't connect to malicious websites, even if an employee inadvertently clicks a dangerous link.
