The Castle Analogy: How to Best Defend Against Cyber Attacks

Cyber-attacks are becoming an increasing threat to businesses of all sizes. Employees might notice simple changes to their homepage, endless pop-ups, strange new programs, phishing emails that look legitimate, frequent crashes or even complete file lockout due to ransomware. Unfortunately, these experiences are becoming more prevalent as technology evolves and is adopted by more businesses. According to research from Cyber security Ventures, a business fell victim to a ransomware attack every 40 seconds in 2016. They now predict that by 2021, that statistic will shrink to only 11 seconds on average between attacks. And, to make matters worse, it can be tough to choose the right cyber security strategy and to understand what is really needed. So, let’s break it down by examining Intechtel’s four cyber security layers using the analogy of a castle for the sake of this blog. The castle represents a computer or device within a network.

The 4 Layers of Protection

  1. Managed DNS Network Security – The Moat
  2. Managed Firewall with IPS – The Outer Wall
  3. Managed Anti-Virus – Castle Guard
  4. Ongoing Employee Training – The Royal Decree

The Moat: Managed DNS Network Security

Our managed DNS service could be compared to the moat surrounding the castle. The large protective moat is intended to keep the bad guys (hackers) from reaching the castle. Managed DNS network security blocks, detects and contains advanced attacks and potential threats before they can cause damage. This type of cyber-defense uses predictive security using machine learning and AI.

The Outer Wall: Managed Firewall with IPS

Like a moat, the outer wall is intended to keep the bad guys out. A managed firewall with IPS (intrusion prevention system) is like that tall outer wall surrounding the castle and provides an additional layer of security. And much like how the wall’s gates allow or deny access, firewalls use rules to allow in harmless traffic or to keep out unwanted visitors.

Castle Guard: Managed Anti-Virus

Knights were assigned to guard the castle whether the threat was inside or outside of the actual castle walls. In the same way, managed anti-virus is installed on a computer and either prevents attacks from entering or finds threats within the device to be eliminated. Intechtel monitors and eliminates identified malware providing a hassle-free experience for customers.

The Royal Decree: Ongoing Employee Training

Although “royal decree” may be a stretch, there are certainly some important rules that every employee needs to understand in order to keep hackers at bay. If employees aren’t careful, they may unknowingly invite the enemy right into the heart of the castle. That’s where Intechtel’s hands-on training and digital classes come in. Intechtel can ensure that each employee learns and demonstrates an understanding of cyber security risks and defenses. This layer of protection is vital in any business with multiple employees. In addition, Intechel can create parameters and access barriers to lower risk from inside threats.


Each layer of protection serves an important security purpose. While any one layer is effective, the combination of all four creates a powerful defense strategy. Keep in mind, Intechtel is ready to respond if or when your business is faced with a cyber threat. It should also be said that no company can guarantee 100% protection against cyber-attacks, but with a combination of software, services, and employee training, Intechtel can substantially mitigate potential cyber security risks to an organization. For more information call (208) 635-4400 to speak to a cyber security specialist.
